Eastern Boundary Upwelling Systems (EBUS) disproportionately contribute to global productivity and fisheries. We looked at response of phytoplankton to climate change in these regions and found that productivity declines in 25% of the area, which would impact livelihoods of coastal communities.🌊

🌊 The GO-BGC @globaloceanbgc.bsky.social project nears its end on Oct. 31 when 500 @bgc-argo.bsky.social floats with chemical and biological sensors for ocean health will have been deployed. The array will then begin to decline as there is no future funding to replace floats as batteries are 1/2

Fantastic review on the ocean carbon cycle and climate led by Laure Resplandy that pulls together impressive budgets and tackles some key narratives 🌊 www.science.org/doi/pdf/10.1...
Integrated perspective on ocean carbon cycle:
Untangling facts, fluxes, and fictions
Laure Resplandy1*, Marina Lévy2, Laurent Bopp3
The ocean carbon cycle spans multiple scales and reservoirs, challenging efforts to build a coherent picture and
fostering misconceptions or fragmented narratives in science and public discourse. Common examples include
the belief that the biological processes control the ocean’s carbon sink (i.e., fraction of human CO2 emissions ab-
sorbed by ocean), that restoring coastal ecosystems is highly effective at mitigating climate change, or that whales
substantially contribute to carbon sequestration. We provide a comprehensive review of living and nonliving
ocean carbon stocks and fluxes—from plankton to mangroves, whales, fish, and plastics—and an integrated per-
spective on global ocean carbon cycling, disentangling well-­ supported insights from misconceptions. This syn-
thesis reaffirms the ocean’s key role as a physics-­ and chemistry-­ driven carbon sink, while clarifying the limited
contribution of coastal and open-­ ocean ecosystems to carbon sequestration and climate mitigation. We caution
against frameworks that justify marine conservation through climate mitigation—a narrative useful to draw
attention, but not always robust and unnecessary, since marine biodiversity is worth preserving regardless of its
impact on carbon.
