Opportunities for earth observation to inform risk management for ocean tipping points
RA Wood, JA Baker, G Beaugrand, J Boutin… - Surveys in …, 2024 - Springer
As climate change continues, the likelihood of passing critical thresholds or tipping points
increases. Hence, there is a need to advance the science for detecting such thresholds. In …

Characterizing the marine iodine cycle and its relationship to ocean deoxygenation in an Earth system model
K Cheng, A Ridgwell, DS Hardisty - Biogeosciences, 2024 - bg.copernicus.org
Iodine (I) abundance in marine carbonates (measured as an elemental ratio with calcium,
I/Ca) is of broad interest as a proxy for local/regional ocean redox. This connection arises …
