SOCAT v2026 is released today, with 2.8 million new observations! Download the new version from socat.info/index.php/ve... The annual poster summarising the key points of the release (including the continued decline in observation coverage) is available: socat.info/wp-content/u...

Many years in the making, this new synthesis puts a more accurate number on soil organic C and N stocks stored away in Arctic river deltas large and small: Fuchs et al have collected soil data from these deltas and estimate a pool of ~57.7 billion tons of carbon. www.nature.com/articles/s41...

Everyone, take a note of this, please. Ocean alkalinity enhancement does hardly counter ocean acidification.

Jens Daniel Müller@jens-d-mueller.bsky.social · 7mo ago

🧪 Why? This outcome follows directly from marine CO₂ chemistry: under constant atmospheric pCO₂, even substantial increases in alkalinity lead to only small changes in pH and carbonate ion concentration.
