Tags on leatherback turtles reveal by-catch hotspots
A study using satellite data from tagged leatherback turtles has identified possible “by-catch hotspots” in the Pacific Ocean.
By tracking 135 turtles, researchers highlighted areas where the critically endangered animals were likely to come into contact with fishing vessels.
The authors hoped the findings could be used to help cut the number of turtles accidentally killed as by-catch.
The paper appears in the Proceedings of the Royal Society B journal.
The species, scientifically known as Dermochelys coriacea, is globally listed as vulnerable by the International Union for Conservation of Nature’s Red List of Threatened Species.
However, conservationists have identified a number of distinct populations in the world’s various oceans. Within the Pacific, the two populations – eastern and western – are considered to be critically endangered.
For this study, data was collated from numerous projects between 1992 and 2008, explained lead author John Roe from the University of North California’s Pembroke campus.
“To really get an idea about where the leatherbacks go, you have got to have turtles tagged from multiple locations,” he said.
“So it took getting just about everyone who has put a satellite tag on a leatherback for other research purposes to collaborate to get a sample size large enough to allow us to answer that question.”
Dr Roe and his colleagues from a range of US and Costa Rican institutes then integrated the turtle location data with similar data of where the longline fishing activity in the Pacific Ocean was highest.
“We used that data to overlay with the data of the areas the turtles were using in order to figure out where the turtle hotspots matched with the fisheries hotspots to identify the areas where by-catch was most likely to occur.”
Writing in their paper, the team observed: “For East Pacific nesters, an area of potential risk occurs along the primary leatherback migration corridor between Costa Rica and the Galapagos Islands.
“For the West Pacific population, …the greatest by-catch was predicted to occur adjacent to nesting beaches in north-west New Guinea.”
They added that the analysis represented the largest compilation of data of its kind.
However, Dr Roe said that more tagging data was required in order to establish a more detailed picture.
“We need to target these areas to see if the turtle persistently use these areas over and over again,” he said.
“That would provide really useful information in the management of by-catch because the fisheries authorities would have that knowledge and adjust their fishing efforts accordingly.”
He added: “We are just trying to highlight some areas to make it easier to look for these needles in a haystack.
“The idea now is to try and get some more refined information in those targeted areas but we now know where and when to look, and where to concentrate our efforts.”

Reefs Go Live returns for new season
CCMI brings the ocean directly to classrooms around the world through live-stream lessons from underwater
In 2018, the Central Caribbean Marine Institute (CCMI) launched Reefs Go Live, their innovative, flagship education programme that live-streams directly from underwater on the coral reefs in Little Cayman to students in classrooms around the world in real time. For the 2022 season, the four episodes of Reefs Go Live reached more than 107,000 viewers in 22 countries. CCMI’s Reefs Go Live team hopes to expand their reach with four new episodes and supplemental teaching resources to help integrate the material into classroom lessons.
Science Communications & Development Manager for CCMI, Beth Chafin, is excited to be part of another year of Reefs Go Live:
“Knowing we have an audience that spans the world, our team is energised as we plan and implement our Reefs Go Live season for 2023! We feel that creating a connection to the ocean and sharing the beautiful coral reefs of Little Cayman with others, both locally and abroad, is one of the most important ways to increase support for critical, timely issues such as marine protection and sustainability. At CCMI, we are fortunate to have these stunning reefs at our doorstep; not everyone is so lucky to be this connected to coral reefs, but healthy coral reefs are vitally important to everyone on earth. Bringing the ocean into classrooms and homes through Reefs Go Live allows us to share the work we do at the Little Cayman Research Centre, facilitate real-time interactions between viewers around the world and our experts in the field, and inspire the diverse audience to take positive action for the future of coral reefs.”
The first episode of 2023 will take place on Friday, 31st March at 10 am Cayman time (UTC -5h). The episode, ‘Finding Hope on our Reefs’, will feature what CCMI’s long-term monitoring of Little Cayman’s reefs shows us. The data from the annual surveys reveals important trends in reef health over time that reflect global threats and the benefits of strong local protection. Reefs Go Live hosts will explain why this annual monitoring is important and what the results tell us about the future of our coral reefs that we all depend upon. Viewers of each episode will be able to ask questions of the diver and participate in polls through the online platform to make Reefs Go Live an interactive experience.
Additional episodes for this year will run at 10 am (UTC -5h) on the following dates:
Thursday, 11th May: Adaptation on Coral Reefs
Wednesday, 24th May: Reef Resiliency & Restoration
Thursday, 8th June: World Ocean Day – 25 Years of Coral Reef Research
Registration for Reefs Go Live is free and is only required once to receive access to all episodes: https://donate.reefresearch.org/rgl2023.
Reefs Go Live provides an opportunity for students from all over the world to engage with the stunning ocean environment in its most natural format. As coral reefs around the world face unprecedented pressure, generating increased engagement with these precious ecosystems creates an opportunity to promote marine sustainability in a positive and fun way.
Reefs Go Live utilises streaming technology with underwater video and audio equipment to enable real time broadcasting from Little Cayman’s stunning coral reefs. Little Cayman, a Mission Blue Hope Spot, hosts one of the healthiest reef ecosystems in the Caribbean, which overall remains healthy and shows resiliency to climate change impacts. The broadcasts and education materials draw connections from CCMI’s current research conducted in Little Cayman to the national science curriculum and key ocean literacy principles, making CCMI’s work relevant and accessible to students and viewers of all ages, and emphasizing the relationship that we all have to coral reefs, no matter where we are.
Reefs Go Live is a free education programme that is made possible by the generosity of The Edmund F. and Virginia B. Ball Foundation. To register for the broadcasts and teaching resources, please visit: https://reefresearch.org/what-we-do/education/reefs-go-live/

PADI partners with global skincare brand Medik8
PADI®’s global non-profit the AWARE Foundation™ is teaming up with leading sustainability-focused skincare brand Medik8 to save our most critical ecosystem on the planet – the ocean.
As the new corporate sponsor of the PADI AWARE Foundation’s 2023 Community Grant Programme, Medik8 will be supporting four grassroots conservation projects that range from protecting megafauna like turtles and whales from entanglement to fuelling hands-on citizen science initiatives like seagrass restoration.
The PADI AWARE Community Grant Programme is designed to award ocean protection initiatives that are in direct support of the United Nations Decade of Science for Sustainable Development in five distinct categories: coral restoration, developing marine protected areas, eliminating marine debris, reducing the effects of climate change, and protecting species threatened with extinction like sharks and turtles. In 2022 PADI AWARE™ dedicated nearly one-quarter of its public funds to empower local communities to take action for our shared blue planet.
“Last year we launched the Grant Programme to directly support PADI Members and NGOs driving meaningful conservation projects, often who have little or no funding support,” says Danna Moore, PADI AWARE Foundation’s Global Director. “This year, due to the collaboration with Medik8, we can provide more resources directly to local communities that need them most. Medik8 is a like-minded organisation that shares our science-based, sustainability-driven, and community-oriented values – and will be a strong partner committed to helping us create positive ocean change.”
Medik8’s support of the PADI AWARE Community Grants programme is in line with their ethos of making a positive impact through driving sustainability strategies with everything they do – from reducing carbon impact and waste to investing in being an ethical business with direct social investments. Their connection and deep love for the ocean is rooted in Medik8’s founder Elliot Isaacs, who is a PADI Master Scuba Diver™.
“As a brand, we strongly believe that increased social investment will allow us to make a more significant mark on wider society,” says Alexandra Florea, Head of Sustainability at Medik8. “Working with grassroots organisations who understand exactly what is needed on the ground will mean we can generate the greatest impact. We chose PADI as our long-term charitable partner because, like us, they put science at the heart of everything they do to bring about positive results.”
The PADI AWARE Grantee projects Medik8 is sponsoring fuel the impact of local citizen science initiatives driving global change like Kosamare Seagrass Restoration in Greece, a grant recipient from 2022 and now 2023. The other three grantee projects have also been selected and range from marine debris removal to climate change mitigation – and are set to be announced in the coming months.
The PADI AWARE Community Grant programme is open to all PADI Dive Centres around the world, along with locally-based NGOs and charities working on marine conservation issues that operate on a budget below $1 Million USD.
“With incredible partners like Medik8 who are equally committed to creating positive ocean change, a swell of hope for our shared blue planet is becoming stronger with every project we support – further proving that the ripples from local action really do have a global impact for us all,” says Moore.
The next round of proposal submissions is on 4 April 2023, with more information at www.padi.com/aware/grant-funding-criteria.
