High latitude deep water upwelling has the potential to control global climate over glacial timescales through the biological pump and ocean-atmosphere CO2 exchange. However, there is currently a lack of continuous long nutrient upwelling records wit... Read More about Coupled climate and subarctic Pacific nutrient upwelling over the last 850,000 years.

Journal Article
Kender, S., Ravelo, A. C., Worne, S., Swann, G. E. A., Leng, M. J., Asahi, H., Becker, J., Detlef, H., Aiello, I. W., Andreasen, D., & Hall, I. R. (2018). Closure of the Bering Strait caused Mid-Pleistocene Transition cooling. Nature Communications, 9(1), Article 5386. https://doi.org/10.1038/s41467-018-07828-0

The Mid-Pleistocene Transition (MPT) is characterised by cooling and lengthening glacial cycles from 600–1200 ka, thought to be driven by reductions in glacial CO2 in particular from ~900 ka onwards. Reduced high latitude upwelling, a process that re... Read More about Closure of the Bering Strait caused Mid-Pleistocene Transition cooling.
