Climate change effects on ocean biogeochemistry


Project Description

Human-induced climate change is expected to affect ocean biogeochemistry through increasing temperature, ocean acidification and deoxygenation. However, the implications of these changes for marine ecosystems are not well understood. We need to know when climate change effects will become apparent in the marine environment and how combinations of conditions (such as deoxygenation and ocean acidification) will arise. To do this, we need to quantify the expected climate change related signals in the ocean from predicted changes to the Earth system between the current day and the future. In addition, we need to improve our understanding of what is required (in terms of observational coverage, frequency, length of record etc.) to detect climate change signals in ocean biogeochemistry, which will allow optimal sampling strategies to be devised. Global climate models allow the natural variability and climate change trends in marine biogeochemistry to be explored, both in the recent past and into the future under different anthropogenic emissions scenarios. As part of the Intergovernmental Panel on Climate Change (IPCC) process, output from multiple different models run under several future scenarios is available which allows assessment of the future state of ocean biogeochemistry.
