Andrew K. Sweetman is the leader of the Deep-Sea Ecology and Biogeochemistry research group and a professor of deep-sea ecology at the Lyell Centre for Earth and Marine Science and Technology, Heriot-Watt University, Edinburgh, UK. He holds a PhD in deep-sea ecology from the Max Planck Institute for Marine Microbiology (Germany), and has held research positions at various world-leading research institutions including Woods Hole Oceanographic Institution, Florida State University, the University of Maine, the University of Hawaii at Manoa, and the University of Bergen (Norway).
Andrew is an expert on seafloor biodiversity and ecology and has a strong focus on the impact of anthropogenic stressors on shallow and deep-sea benthic ecosystems. Over the last 12 years, he has generated approximately 10 million GBP of research funding and led/ co-led a total of 27 research projects (funded by National Oceanic and Atmospheric Administration [USA], the Norwegian Research Council, the European Union, the Malaysia Research Council, UK Seabed Resources LTD/Lockheed Martin, Gordon and Betty Moore Foundation [USA], DeepGreen Metals Inc, Natural Environment Research Council [UK], Engineering and Physical Science Research Council [UK], Global Challenges Research Fund [UK]) on diverse topics including assessing the effects of i) invasive species (and their removal) on benthic biogeochemistry and ecosystem functioning, ii) aquaculture on deep-sea fjord ecosystems, iii) carbon dioxide release from carbon capture and storage (CCS) reservoirs on continental shelf ecosystems, iv) mine-tailings deposition, massive sulfide and polymetallic nodule mining on deep-sea ecosystems, v) global warming on polar ecosystems and vi) synergistic climate change stressors on shallow and deep-ocean systems. He has also been leading projects to assess the importance of jellyfish blooms in the biological C-pump, and the effect of dead jellyfish (from jellyfish blooms), wood and kelp material on deep-sea benthic environments.
