While the ocean as a whole is losing oxygen due to warming, oxygen minimum zones (OMZs) are maintained by a delicate balance of biological and physical processes; it is unclear how each one of them is going to evolve in the future.

Professors Laure Resplandy and Daniel Sigman explain how the ocean absorbs heat and carbon dioxide, providing a buffer against climate change. Researchers are modeling the long-term impacts to marine ecosystems and climate. (Video by Video Production Support and the Office of Communications)

Looking for Postdoctoral Researcher in the area of ocean physical and biogeochemical coupling to work with Professor Resplandy in the Princeton University Geosciences department.

In 2001, off India’s coastal state of Goa, the shrimp catch dropped by 80 percent in just a few years. The die-off was later traced to a dip in the ocean’s oxygen level. “It was a massive event that almost collapsed the fisheries on the western Indian coast".

New study estimate ocean warming using atmospheric O2 and CO2 concentrations. We are aware the way we handled the errors underestimated the uncertainties.  We are working on an update that addresses this issue.  We thank Nicholas Lewis for bringing this to our attention.

From September 2-7, 2018 more than 300 scientists from 33 countries met in Kiel, Germany, to discuss the decline of ocean oxygen, its causes and consequences.  Prof. Resplandy's keynote presented how we can monitor oceanic oxygen loss using atmospheric measurements.
