The changing polar oceans and why their biology matters to us all

Talk and discussion with Oceanographer, Prof Geraint Tarling

The polar oceans are inhospitable, inaccessible and remote. They remain the least studied of all ocean regions. They also play a crucial role in how our planet operates. Data and samples from these regions are hard won by scientists who have toiled over many decades to obtain them. What has been revealed is an underwater world, teaming with life, containing species with adaptations found no-where else on Earth. The ecosystems they are part of have a global influence on both the productivity of all other ocean regions and the levels of CO2 in our atmosphere. The polar regions are also experiencing some of the most rapid environmental changes on Earth and there are big questions on how quickly its biology can adapt. In this talk I will describe the latest research we are carrying out in ice-edge environments and consider the future fate of these globally important ecosystems.

Professor Geraint Tarling has been a biological oceanographer for over 25 years, and has carried out research at the National Oceanography Centre, the Scottish Association for Marine Science and the British Antarctic Survey, where he now heads the Ecosystems team. Over his career, he has tackled a number of issues considering how influences on marine organisms at small scales have major impacts on large-scale processes. His research has contributed particularly to our understanding of how carbon (C) is transported through the marine system and sequestered (i.e. taken out of the system), which is important to regulating global climate. Most recently, he is the Principal Scientist for BIOPOLE, a £9M multi-institute UK programme that is determining how marine ecosystems in both polar regions regulate the balance of carbon and nutrients in the world’s oceans and their influence on global fish stocks and carbon storage.
