Helen Findlay completed an MSc in oceanography at the National Oceanography Centre, Southampton before moving to Plymouth to do a PhD in biological oceanography at Plymouth Marine Laboratory (PML). During her PhD Helen carried out laboratory and field research in the UK and in the Arctic. In 2010 she was awarded the Lord Kingsland Fellowship at PML to continue investigating the impacts of climate change and ocean acidification on marine ecosystems. Her current research involves fieldwork in the Arctic Ocean, teaming up with the Catlin Arctic Survey, but also involves research in the UK Shelf Seas. Helen has been a STEM Ambassador and involved in outreach activities for the past 5 years.

Ceri Lewis is an experienced marine biologist with expertise in how environmental change and pollution affects reproductive processes in marine animals. Ceri currently holds a lectureship position at Exeter University and is conducting research into how marine animals adapt and respond to environmental change, such as ocean acidification, climate change and increasing pollution. As part of this research Ceri joined the Catlin Arctic Survey in 2010 and 2011 to study ocean acidification processes in the High Arctic during the winter-spring transition period, enduring temperatures as low as -40°C in the pursuit of vital scientific data on climate change. She also helps run a tropical marine ecology field trip to study the coral reefs in the Bahamas and recently did a research cruise into marine microplastics off the coast of Maine from a 60ft yacht.

Emily Penn is a skipper, ocean advocate and artist. She spends her time leading expeditions and taking a wide variety of people to incredible places to address key global issues as part of Pangea Explorations, an organisation she helped to establish. Emily has also led the largest ever community-led clean-up from a Tongan Island, trawled for microplastics in the Arctic North-West passage and sailed the globe on Earthrace. She is the youngest, and only female, to be awarded Yachtmaster of the year.

Alex is Professor of Conservation Biology at the University of Oxford. His research focuses on biodiversity hotspots in the oceans. This work has focused on the deep sea and also on tropical coral reef ecosystems. He also works on marine policy specifically related to the sustainable management of marine resources, particularly deep-sea fisheries. Alex is an advisor to the Global Ocean Commission and on the Programme Committee of WWF. In the past, Alex has been a key scientist involved in the Core Programme on Biodiversity at the British Antarctic Survey and has worked with the Zoological Society of London.

Mark Brandon is an award winning Reader at the Open University. His particular interests lie in using robotic and remote sensing technologies to investigate the interactions between the sea and the ice in the Arctic.

He is also a pretty nifty photographer and has taken some incredible images for #icephoto Wednesday.

Anjani Ganase grew up in the twin island nation of Trinidad and Tobago. Her grandfather was a fisherman and taught her to appreciate just how important our coral reefs are.

Coral reefs are facing unprecedented threats from human activities, but in order to protect them properly, we need to understand more about their structure and function. Anjani is adding to this knowledge base as part of her PhD in Australia.

Jo Royle is on a mission to raise ocean ecosystem awareness at a global scale. As an experienced skipper, Jo has visited some of the most beautiful and remote places on Earth.

Jo took part in the Plastiki expedition, sailing for five months across the Pacific on a boat floating on 12,000 reused plastic water bottles! On board the team pioneered sustainable technologies aimed at reducing the impact of single use plastics.

Being a field assistant means Lucy Quinn spends much of her time outside of the UK, visiting some incredible places. She describes her job as being in a “living nature documentary”!

Currently she studies ecology on Bird Island for the British Antarctic Survey. Her interests lie in different species of albatross which are facing many threats, from fishing, changes in food supply, species introduction and marine pollution.
