We should study this change as scientists. Monitor the intended outcomes of NSF-funded research: Discovery (probably measured by proxy via publications and by expert elicitation), training graduate students, and outreach/public-facing events. Then compare outcomes pre- and post these changes.
🧵 NSF is reducing external review requirements and eliminating routine expert panels, citing staff shortages that this administration implemented. This change expands program officer authority. But the solution to flawed accountability isn't less public accountability.

NEW from me - NSF cancels grant scheme for social science research.
Seems the NSF quietly archived ALL calls for DDRIG grants in the SBE directorate. This is a massive blow for PhD students wanting to do cutting-edge social science research. 🏺🧪

Marine heatwaves modulate food webs and carbon transport processes - Nature Communications
A decade of BGC-Argo and plankton records shows North Pacific heatwaves reshape food webs and trap small particles in midwater, slowing deep-ocean carbon export. Impacts vary by event, underscoring the need for sustained ocean monitoring.
