Investigating Coral Reef Acoustics to Aid Reef Restoration

Words by Ben Williams, 2019 BioScience Graduate

Most people are aware coral reefs throughout the world are struggling one way or another. A range
of issues are responsible including overfishing, pollution and climate change induced bleaching to
name a few. However, coral reef communities provide valuable ecosystem services to a vast number
of individuals, it’s estimated One Billion people have some degree of dependence on these
ecosystems. With much of the world’s reefs degraded or lost it makes conserving those that remain
vital, and restoration of former reefs an important endeavour to many individuals.

The Marine Bioacoustics group in Exeter focuses much of their efforts on understanding the
soundscapes of coral reefs. These soundscapes encompass the entirety of the sound that can be
heard on particular spots of the reef and can be collected using underwater microphones we call
hydrophones. Emerging research suggests a lot can be determined about a reef from a few key
parameters within its soundscape which could be used to indicate the health of the surrounding
reef. A great example is shown in the spectrograms below, where you can hear an audible difference
between the soundscape of a healthy reef and that of a degraded reef:

This short acoustic clip first plays us the buzz of a healthy reef, followed by the quieter setting heard on a degraded reef

A group of us from Exeter’s Marine Bioacoustics group are currently out in Indonesia exploring reef
acoustics further. We’re collaborating with a project set up by Mars™, who have been working on an
intuitive way to restore the reefs in South Sulawesi. They use two key methods in doing so, the first
is coral propagation, where small samples of coral are clipped off live colonies and transported
somewhere new where they grow back at a faster rate than if left on their original colony. The next
step is to attach these to a skeleton system they call ‘Spiders’, which provide a substrate for new
corals to colonise and elevate them slightly above the reef bottom to provide the water flow needed
to bring nutrients to the growing coral. The Mars™ project has implemented large areas of these
spiders around two islands off Makassar with an impressive degree of success in their ability to
restore the reef.

This photo shows some of the several month old spiders placed by the Mars™  team which are showing an impressive rate of growth.

Our team from Exeter is particularly interested in the difference between the soundscapes of healthy and degraded reefs. We’re visiting the Mars™ restoration efforts to help explore the differences in soundscapes between their restored sites, degraded sites and baseline healthy sites. The hope is that in the future we will be able to show restored sites match the soundscape of healthy sites, and a quantifiable difference between the restored sites and degraded sites will be observable. We’re trialing this out using hydrophones which we’ve been placing daily on different sites within the reefs to determine whether this is a feasible methodology in comparing the reef soundscape.

We’re also exploring the possibility of using ‘soundscape enhancement’ to help fine tune the ecology of the reef at a local scale to bring about restorative impacts. This is a highly innovative approach in which submersible loudspeakers are placed on patches of degraded reefs where they play recordings that may help recovery of the reef. A proof of concept of this was only recently provided in a 2018 study authored by Tim Gordon, who is now leading the expedition out here in Indonesia, and other members of the
Marine Bioacoustics group. The study found that larval and juvenile recruitment was greater at sites where healthy reef noise was played compared to sites where degraded reef noise was played. The use of soundscape enhancement is therefore of a great interest to restoration programmes like Mars™ in Indonesia, and we’re also out here to help them investigate whether this could be a potentially useful tool for their restoration. This time we’re trialing playback methods that could be used to affect the ecology of adult fish within the reef, primarily regarding their grazing behaviour which is a key process in controlling algae overgrowth at degraded sites.

A Day in the Life of a Marine Bioacoustics Intern

Words by Ellie May and Ben Williams, ExeterMarine Undergraduate Students

 

Hi there, this is Ellie May and Ben Williams giving you an update on our current trip to the Indonesian island of Sulawesi to assist Tim Gordon and Lucille Chapius in looking at the soundscapes of healthy and degraded reefs. We are currently based in the city of Makassar, where we take one of MARS symbioscience’s boat out to the islands of Bontasua and Badi to measure the acoustic complexity, richness and invertebrate snap rates of different spots around the reef. Our first day out on the islands consisted of observing and understanding the scale of restoration provided by MARS via their spider systems, in which they attach fragments of healthy reef colonies to a metal spider structure in order to promote growth in degraded areas. Our interest is understanding whether adult fish respond to the soundscapes of different reefs, and whether playing recordings of healthy soundscapes will increase not only the abundance of fish but also their rate of grazing.

The spider structures used by MARS to promote coral growth.

A typical dive day consists of being up at 7.30am to prepare our equipment and make any final adjustments before we head out to the islands at 9am. A member of the MARS team will take us to the relevant reef spot, where we deploy hydrophones to sample the baseline of the reef at various times of the day. GoPro’s are set up adjacent to the hydrophones in order to test the quality of sound they record in comparison to the hydrophones. Both Ben and I have our own side projects we are working on throughout the duration of our time here. I’m trying to prove that GoPro’s can be just as useful as hydrophones in recording reef soundscapes, which then allows any individual with access to a GoPro and free coding applications to discriminate between key components of sound, massively increasing the data sets researchers can use to measure reef health.

Our daily commute!

 

During our first week, our time was split between days in the water and daily trips to the local hardware stores in order to find extra bits of equipment we needed, and safe to say we had to be pretty inventive! However, as the days pass, we’re all getting into the swing of things and learning which tasks need prioritising and where we individually fit in to the project. During our days in the water we are constantly moving between locations to record as much as possible, as well as setting up quadrats to measure fish grazing rate in response to healthy reef sound played through our underwater speaker.

Part of our Speaker system that needs to stay dry!

 

We usually return to Makassar’s port by 5pm, cram all our equipment into a ‘Grab’ taxi and head back to our accommodation for a debrief and evening plan. Luckily as food is so cheap we tend to go out for dinner every night, and try to sample a mix of local Indonesian food as well as a few more Western cuisines. Gado-Gado is our favourite local dish and we have a tally of how many our team can eat within the approximate month we are all staying here, as this is the only vegetarian Indonesian dish we have found as of yet!

After supper and a debrief we get on with preparing everything for the next day in the field, whether that be making slight adjustments to the equipment to decrease set up time or cutting and editing our audio recordings to make the data analysis in the future a lot less time consuming. We tend to get relatively early nights here as everyone is usually shattered after a long day that is both mentally and physically taxing! Often in the evenings Ben and I reflect on how truly privileged we are to be able to learn about bioacoustics on such beautiful and diverse reefs, and be able to have a first-hand insight into the incredible work MARS are doing on coral restoration. To be able to see both the logistical planning and fieldwork skills it takes to organise and run such a project is amazing, especially as a current undergraduate. Observing the differences between the restored and untouched reefs really consolidates how important restoration projects are, and hopefully there is a much wider community finally realising that big changes are needed in order to save the biodiversity of our reefs.

Happy #SeaTurtleWeek! Check out these turtle-y awesome Sea Turtle researchers!

As we segway from #WorldOceansDay into #SeaTurtleWeek we though we would share with you all an insight into just some of the research being carried out by @ExeterMarine at the Univeristy of Exeter!

Below, members of the Marine Turtle Research Group led by Profs Annette Broderick and Brendan Godley share their research and why they enjoy working with these ancient animals.

Ceren Barlas, PhD student 

Hello! I am a Ph.D. Biological Sciences student in the Marine Turtle Research Group at the University of Exeter, supervised by Brendan Godley and Annette Broderick. My research focuses on the marine plastic pollution in the Mediterranean and how it affects the physical and biological environment. The recent experiments at Alagadi beach investigated the effect of macroplastic contamination on the beach, where we compared the effects of different contamination levels and different plastic types on sand temperature. This type of contamination and resulting effects are important for sea turtles, as a change in sand temperature can change the sex ratios of the hatchlings and affect the reproductive success of future generations.

Find out more about the turtle conservation project at Alagadi Beach here.

 

Dr Ana Nuno, Research Fellow

How can we better protect sea turtle populations worldwide? We need to understand the root causes of problems affecting them… and that often means understanding how people use them (e.g. diet and culture). My research combines information about sea turtles and people so that we can design robust conservation programmes. For example, my research explored sea turtle farming as a way of promoting sustainable use of turtles in the Caymans Islands and assessed drivers of the illegal trade of marine turtle products in Cape Verde. There are so many different ways people value sea turtles… it’s crucial understanding these different perspectives so that we can find ways forward!

Julia Haywood, PhD Student

I am a marine spatial ecologist working on female loggerhead turtles in the Mediterranean Sea. Using satellite telemetry, stable isotope analysis, and satellite remote sensed data I aim to unravel the mystery of what they get up to when they aren’t nesting. Where do they go, how do they find their way there, what is so special about that place, and how do human activities affect them?

Dr Rita Patricio, Postdoctoral Researcher

Dr. Patricio is a Postdoctoral researcher at MARE-ISPA, Instituto Universitário, Portugal and University of Exeter, UK.

I research the green turtle connectivity along the West African coast and the Atlantic, using satellite telemetry, to assess their migratory routes, and genetic analysis, to investigate their origins. Other aspects we are also looking into include climate change impacts on the greatest green turtle population in Africa, habitat selection, and status of the critically endangered hawksbill turtle in the Bijagós Archipelago, Guinea-Bissau.

I work with an amazing team of students, researchers, national technicians and community members. Our work contributes to improve sea turtle protection, for example informing the zonation of MPAs, or suggesting regulations at priority sites, it helps to raise awareness, through the participation of local communities in conservation work, and it builds the capacity of national teams involved on research. Plus, disseminating our research results and activities boosts visibility enhancing funding opportunities for conservation.

It is fascinating to work so close to these charismatic and ancient-like creatures. Marine turtles are very symbolic to many coastal African communities, representing abundance, power, and fertility. Understanding local cultures and working together for the conservation of marine turtles for the coming generations it is most fulfilling.

Casper van de Geer, PhD student

I have recently started my PhD, where I will be looking into the ecology and conservation of marine turtles in Kenya. The fieldwork and data collection has been carried by the team at Local Ocean Conservation (LOC), founded in 1997 and based in Watamu, and is ongoing. Before starting my PhD I was the manager at LOC for four years.
I will be investigating turtle nesting trends and incubation temperatures, as well data collected through the LOC’s Bycatch Release Programme. The Bycatch Release Program aims to minimize mortality of turtles resulting from interactions with the artisanal fishing sector, which has been recognized as one of the major threats to marine megafauna in the Western Indian Ocean region. I will also be carrying out an assessment of this program to see if it should and could be replicated elsewhere.

There is still much we do not know about turtles in Kenya or indeed the wider Western Indian Ocean, so I’m excited that my research will be able fill some of these knowledge gaps and contribute towards effective conservation strategies for these incredible marine reptiles. These contributions will also demonstrate how important local grassroots conservation efforts, like those of Local Ocean Conservation, can be if they are carried out properly and consistently.

Dr Liliana Poggio-Colman, Postdoctoral Researcher

I’m a postdoc researcher working with the ecology and conservation of a small and critically endangered leatherback turtle population nesting in Espírito Santo, Brazil. We work together with @ProjetoTAMAR in Brazil to monitor them and investigate their nesting ecology, population trends, habitat use and threats. I love being able to work with such magnificent creatures.

#WorldOceansDay – gender and the oceans

This #WorldOceansDay we want to celebrate our academics who are working on understanding gender roles and how this impacts both the individual and society in coastal communities. In this post we introduce you to four researchers who are all working on different aspects of the influence gender has on roles, livelihoods and wellbeing within coastal communities.

 

Dr Tomas Chaigneau

Lecturer in Social Sciences for our Environment at the University of Exeter, Environment and Sustainability Institute (ESI) in Cornwall.

I am a social scientist who studies the relationship between the natural environment and peoples’ wellbeing. This involves understanding how individuals derive wellbeing from the coast but also how their actions can impact their adjacent environment. Through an interdisciplinary approach, I explore how conservation and natural resource management measures are contributing to wellbeing and poverty alleviation. In particular, the disaggregated and gendered nature of this work uncovers important trade-offs between the needs and wants of different individuals within communities and environmental management. This work seeks to find ways to reconcile these whilst minimising negative consequences for current and future generations.

Dr Madeleine Gustavsson

Research Fellow at the Univeristy of ExeterMedical School, European Centre for Environment and Human Heath (ECEHH) in Cornwall.

My research focuses on fishing families and communities – particularly concentrating on the small-scale fishing sector. I hold an ESRC New Investigator research grant titled: “Exploring the changing role(s), identities and wellbeing of women in small-scale fishing families.” The study focuses on how women in both the UK and Newfoundland, Canada, are sustaining small-scale fishing families. The project’s main goal is to investigate the role of women in responding to financial pressures in the fishing sector and to understand what this means to these women in terms of identity and wellbeing. 

We’ll be collecting data by interviewing people and listening to their experiences. This kind of research is called a qualitative study and our participants are the experts. We listen to their voices so we can include their knowledge in our research. We will talk to women about their experiences in the forefront of fishing businesses, and also learn about their roles in areas related to fishing—such as working in fish processing, markets, and restaurants

In the coming year we will conduct semi-structured interviews with policy makers and government representatives in the UK. We will explore how women can be supported by future fishing policies, particularly those following the UK’s exit from the European Union.

A further goal of the project is to establish a UK-wide network for women in fishing families. The Women in Fishing Network will help women to connect with each other, share experiences, and offer support.

More information is available here.

Timur Jack-Kadioglu

PhD researcher at the University of Exeter Medical School, European Centre for Environment and Human Heath (ECEHH) in Cornwall.

My research, part of the UKRI GCRF Blue Communities Programme, is focused on how coastal communities in Palawan, the Philippines, perceive and experience livelihoods, and how these are linked with people’s wellbeing. In particular I am exploring how these are shaped by people’s gender, age, ethnicity, and class background.

Through empirical research in a municipality undergoing rapid change, I am seeking to explore how government and NGO narratives compare and contrast with the perceptions and experiences of different community members, and whether there are barriers or facilitators that influence people’s livelihood choice, in particular the most marginalised community members.

Dr Rebecca Short

Research Associate at the University of Exeter Medical School, European Centre for Environment and Human Heath (ECEHH) in Cornwall.

Coming from a marine biology background I have developed an interest in how people and the oceans interact, particularly the balances between the benefits we derive and the impacts we have on the oceans. Recently this has focused on the role women play in the fisheries sector; how we can improve gender equity and generate win-wins for coastal communities. My PhD focused on the use of mosquito nets as fishing gear, an activity of underappreciated importance to women in developing nations which represents both and ecological risk and a socioeconomic opportunity. I am now additionally researching broadly across topics linking human health and the oceans with the European centre for Environment and Human Health SOPHIE project where we aim to set an agenda for the EU that secures the health services we critically rely on from the oceans. 

As I continue my research, both further in to mosquito net fisheries elsewhere and also more generally in to links between the oceans and human health with the SOPHIE project at ECEHH, I know that gender will be a key focus for me. Importantly I also believe it should be a key focus in all research of this kind; whilst I may seem obvious to us now that leaving out half of the picture leads to terrible policies and results we have several centuries of half-baked research to backfill with the full picture!

It’s #WorldOceansDay! A focus on gender and fisheries in Mozambique

This #World oceans Day, Dr Rebecca Short from the University of Exeter Medical School, European Centre for Environment and Human Health (ECEHH) talks to us about her PhD research focusing on gender roles in coastal fishing communities in Mozambique.

Words by Dr Rebecca Short, Research Associate, ECEHH, University of Exeter

I did not know that the women of Cabo Delgado, Mozambique would be so central to my PhD research when I began investigating the coastal fishing communities of this remote part of the country. I was there to take a first look at an issue that has been in the background for a long time, but seldom a main focus for those interested in fisheries; the use of mosquito nets as fishing gear. This is assumed to be a terrible idea. By putting your net in the water with a goal of feeding your family or making a small income you are not only reducing protection from malaria-carrying mosquitoes, but also jeopardising the future sustainability of the fishery by sieving the fragile coral reef waters of fish of any size. This has been much discussed, though little scrutinised, with the result usually being to make it illegal – the case in Mozambique despite this impacting some of the poorest people. This I did know when I began and I must admit I presumed was a necessary evil to preserve the fish stocks for future generations.

It was therefore a bit of a surprise when on my very first day in the city of Pemba, having some lunch near the beach, when I saw a group of women very obviously fishing with their bright blue mosquito nets right by the shore. Surely this was quite risky? When I arrived in the much smaller villages north of the city which were to be my focus much of the same; women in the shallow waters, up to about chest height fishing with several mosquito nets sewn together in groups of three or four. Some days, groups of women fishing as far as the eye could see. Not an objection to be heard or fisheries official to be seen.

My first objective was to try to understand better the who, what, why and how of mosquito net fishing the only way I could think of; by going fishing with them. Whilst making a complete idiot of myself by apparently hauling in the net like a hapless baby, I saw a totally different side of the activity; it was fun. The groups of women were clearly good friends and laughed and joked whilst fishing (with or without my influence I should mention). This, I reflected, was in such contrast to their other main occupation of farming where they spend much of their time alone or with family on a small plot of land.

Early on in my research it was obvious there was more to it for women in what is a very conservative, patriarchal culture. Enabled by the free availability, lack of necessary fishing skills, and importantly perception of mosquito net fishing as acceptable ‘women’s work’ this has become their opportunity to make their own money (which can be more likely to contribute to community development than patriarchal income), to feed their children what is actually particularly a nutritious meal (Kawarazuka &  Béné, 2011), and of course a chance to have a break from the demands of their families! On top of this they had figured out their own economics; allotting catch according to net ownership, friendship loans of cash and food, and divisions of labour. Generating their own small industry. The significance of this should not be underestimated. Mozambique was recently rated 15th lowest in the world in the Girl’s Opportunity Index (Save The Children, 2016), and Cabo Delgado so remote from the capital of Maputo has some catching up to do with the rest of the country. Girls grow up here told that their best bet at a good life is to find a good husband, though divorce is not uncommon. To have an independent way to support your family can be more than survival but a way out of abject poverty.

If you’re wondering where the men are in this story – good question. I couldn’t really find them, and this alludes to the crux of the issue with mosquito net fishing. Because the men were using mosquito nets for fishing, you just probably won’t see them. They are further offshore, fishing with much bigger nets adapted for use over coral reefs where they would normally snag and tear, fishing in bigger groups with much larger catch sizes. This is what is seen as the problem with mosquito net fishing. Accordingly, a taboo is attached to this activity which does not exist for the women and the men hide what they are doing.

These differences are well known to the local people, and women fish so brazenly because they are not seen as a threat to the fishery. Yet nowhere in my preparation for this research, within the media, peer review literature or indeed by talking to officials did this come up. And I shouldn’t have been surprised – women are so often excluded from fisheries research. This may be because globally they play mostly secondary roles as traders, processors or indeed cooks. But even primary activities such as mosquito net fishing and what is probably one of the most widespread activities in small-scale fisheries, gleaning, are routinely disregarded in management and policy formation, whatever the governance system. This is reflected in research which focuses almost exclusively on male fisheries. But we are wising up! The field of gender and fisheries, and indeed gender and the oceans is rapidly growing. Not just as an area of interest, but driven by our increasing understanding of the critical role women play in successful development, conservation and sustainable management.

As I continue my research, both further in to mosquito net fisheries elsewhere and also more generally in to links between the oceans and human health with the SOPHIE project at ECEHH, I know that gender will be a key focus for me. Importantly I also believe it should be a key focus in all research of this kind; whilst I may seem obvious to us now that leaving out half of the picture leads to terrible policies and results we have several centuries of half-baked research to backfill with the full picture!

A Day in the Life of an Arctic Field Scientist

Words by Clara Nielson, University of Exeter PhD Student

A day in the life of an Arctic field scientist

Hello! My name is Clara Nielson and I am a PhD student from Exeter University studying the impacts of global change on marine species in Dr Ceri Lewis’s lab. We are currently at 78 degrees north in a place called Ny Alesund, in Svalbard at the UK NERC Arctic Station for AXA XL Arctic Live with Encounter Edu. We are here to both conduct important research but also to communicate what we are doing to schools around the world.

Clara Nielson and Dr Ceri Lewis in the Arctic

Pulling open the curtains to a view of snow covered mountains and glaciers on the edge of a fjord will guarantee to put a smile on your face and put you in a good mood for the rest of the day. Our usual day starts waking up in the base and heading to the canteen for breakfast. Ny Alesund is home to a range of international scientists all coming and going at different parts of the year and the canteen is the communal hub where everyone can share a meal, and a story or two, before heading off for the day.

Arctic View

Weather permitting (we have had a few base days where we are unable to get out onto the boat due to high winds) we usually spend the day out on Teisten, the research boat, collecting water samples from different parts and depths of the fjord. We are out here to monitor the pH and carbonate chemistry of the seawater, as part of a global ocean acidification project. Ocean acidification is the change in ocean chemistry as a result of increasing atmospheric carbon dioxide levels and this process is happening fastest in the Arctic. The samples we are taking will help fill in the global picture of just how fast this process is happening. We are also sampling for any microplastics that may be in the seawater as the Arctic is also thought to be a hotspot for microplastic accumulation due to ocean currents. We were here last year doing the same sampling, and we did find some plastic, so it will be really interesting to compare our data and that of other long term projects to see how the Arctic is changing. Today it was -7oC, which is pretty cold but add to that the wind chill and we were out in temperatures of about -25 oC. This made sampling slightly trickier than at home as the seawater and all of our sampling gear was freezing pretty quickly, not to mention how cold my hands were getting! Its hard to describe how that sort of temperature feels but basically it’s painfully cold. Thankfully team work, biscuits and a kettle kept everything working!

 

The cold is soon forgotten as once the days sampling is over we can head back to our heated base but the hot shower has to wait just a little longer! First, we need to make sure all our kit is cleaned ready to go again tomorrow and the samples are stored away correctly.

After dinner we spend a bit of time looking through samples and manage to show our Arctic base manager Nick his first sea angel! This is a type of zooplankton called a pteropod, which flapped around our petridish and made this seasoned field man swoon at its beauty.

Frozen equipment is a daily challenge.

Before bed I spend a bit of time with Jamie, from Encountered Edu, going through what I shall be doing tomorrow as it is my day to take part in Arctic Live. Arctic Live is the other important reason we are all here, as alongside our research we are taking part in a live streaming educational lessons and question and answer sessions where we speak to school children live from around the world about our experiences and answer their questions about the Arctic and what it is like to work here. I am looking forward to hearing what questions the children have come up with! Its really cool that we can share what we are doing live from this amazing place, I hope it inspires them.

It is time for bed once we are all set for tomorrow, the 24-hour daylight is making it slightly harder to get to sleep as you feel like it should be the middle of the afternoon, not 11pm but it is important that we all get a good rest.

I feel very privileged to be out in such a stunningly beautiful place and it is without doubt the best place I have ever done field work in. The wildlife here is amazing too, today we saw a Minke whale from the end of the boat which was incredible. The Arctic is at the forefront of climate change where the impacts are being felt first and fastest and is also a hotspot for plastic pollution so it is probably the most important place to be doing this kind of science right now.

It’s World Penguin Day!

 Today is World Penguin Day!

 
Penguins are some of the most recognisable characters amongst the cast of species that call the oceans their home. Whether they love them (almost everyone!) or hate them, people I meet rarely fail to register an emotional response when I tell them I work on penguins. And that’s got to be a good thing this World Penguin Day because, globally, penguins are not fairing well. Of the 18 species of penguin, 11 are undergoing population declines and 10 are considered as threatened on the IUCN Red List. Penguins are threatened by climate change, pressure from fisheries interactions and pollution, amongst other things. But there are successful conservation stories for penguins species too and teams of dedicated people are working to ensure these charismatic species stick around to see many a more World Penguin Day in future.
Have a look at this blog post to find out more about our work to conserve African penguins: http://multimedia.earthwatch.org/a-comeback-story-in-the-making
or this recently accepted review for more information on all 18 species: https://www.frontiersin.org/articles/10.3389/fmars.2019.00248/abstract.
A Penguin-eye view: foraging for fish

Happy World Penguin Day!
