Project
Pathways and emissions of climate-relevant trace gases in a changing Arctic Ocean (PETRA)
The Arctic Ocean is a rapidly changing environment, with rising temperatures leading to an ongoing decline in sea ice and shifting conditions for marine life. Despite the presence of important and complex ecosystems in Arctic waters, there are knowledge gaps in how the Arctic Ocean and its inhabitants will be impacted upon and respond to global climate change.
PETRA (Pathways and Emissions of climate-relevant TRace gases in a changing Arctic Ocean) will combine chemical and biological observations with modelling to investigate the impact of three important stressors – ocean acidification, warming waters, and elevated irradiation – on the cycling of key trace gases in the Arctic Ocean which play a large part in controlling our climate.
The project is funded by the Natural Environment Research Council and forms part of the Changing Arctic Oceans (CAO) programme, which aims to research Arctic Ocean ecosystems and the pressures that they face.
