🌊📊 #SOOS_DATAMonday | #SOOSmap_Month Spotlight!
Today we’re diving into two powerful datasets available through #SOOSmap from @noaa.gov !

🟦 SOCAT v2024 – The Surface Ocean CO₂ Atlas
➡️ Provides high-quality surface ocean carbon dioxide (CO₂) analysis

Introducing the "tree ring plot": a new way to visualize global surface temperatures. Each ring is a year, and each colored cell represents a day in global average temperatures (compared to a 1850-1900 preindustrial baseline).

Bootstrap analysis for the origination rates and extinction rates of calcareous (dotted lines) and agglutinated (dashed lines) foraminifera. (A) Expected (light orange shading) versus actual (dark orange dotted line) calcareous extinction rates, (B) expected (light blue shading) versus actual (dark blue dotted line) calcareous origination rates, (C) expected (light orange shading) versus actual (dark orange dashed line) agglutinated extinction rates and (D) expected (light blue shading) versus actual (dark blue dashed line) agglutinated origination rates. Vertical dashed lines indicate the Big Five mass extinction events; the Phanerozoic time scale is at the bottom of the figure; transitions between calcite and aragonite seas are indicated at the top of the figure and the black gradient bar (middle) represents the approximate duration of the Mesozoic Marine Revolution (MMR). p̂ = origination rate; q̂ = extinction rate.

#WeekendReading: Faulkner et al. (w/
@rowanmartindale.bsky.social;
@chrislowery.bsky.social) on how the test walls of foraminifera change through the Phanerozoic and what might that have to do with ocean chemistry. 🧪⚒️🌊

Map Antarctica without ice

Antarctica without ice🧊🧊🧊🧊

#AWI scientists have developed a new map of #Antarctica in collaboration with @bas.ac.uk. 🇦🇶

It shows the landscape beneath the Antarctic ice sheet more precisely than ever before: the topography of the mountains, canyons and depressions.

Calcium Carbonate to store CO₂ ? The earth’s oceans contain a great deal of dissolved inorganic carbon (DIC) and a decent concentration of calcium (about 10mM).Furthermore the ocean has a hu...

Does making seashells 🐚 in the ocean to drawdown atmospheric CO₂ sound like a good climate solution to you?

Then you’re the target audience of this blog from @mtyka.bsky.social explaining how precipitation of calcium carbonate to make shells uses bicarbonate and actually releases CO₂. 🌊
