Field sampling of macroalgae hosting EBF in Carmel Head (a); The brown native non-calcifier macroalga Halopteris scoparia meadows (b) and the EBF attached to it (b1); The brown invasive non-calcifier macroalga Lobophora schneideri meadows (c) with few EBF attached to it (c1, white arrows). L. schneideri covered by sand (C2).

There are #foraminifera living on seaweed, we call them epiphytes. You'd think that these forams would each have a favorite algae, but not. If any, the two groups seem to share more common responses to external forcing than on each other. 🧪🌊

Part of the #legolab team, lego Jaime and lego Tom start looking at some new lego sediment core. They are surrounded by the tools of their trade; a giant 3D printed foram and lego mass spectrometer.

Watch this space for more #foraminifera, #CO2, and of course... more lego scientists @exoceanlab.bsky.social.

I've taken quite some sediment samples and it's as if I've been either blind all this time or #foraminifera have suddenly flourished. #sediment #citizenscience #protists #amoeba

New in @science.org: Calcifying plankton #coccolithophores, #foraminifera & #pteropods quietly drive the ocean carbon pump. Their traits (incl. “shallow dissolution”) are missing from many climate models. Time to put CaCO₃ back in the picture. #ClimateScience 🌊 doi.org/10.1126/scie... #protistsonsky

How Foraminifera and Their Symbionts Support Coral Reef Conservation

Foraminifera, microscopic organisms some reaching 5 mm, build calcium‑carbonate shells that add to reef limestone and serve as bio‑indicators of water quality. Read more: getnews.me/how-foraminifera-and-the... #foraminifera #coralreef

Microscope images of Globigerinoides ruber (pink) shells from Bay of Bengal core MGS30. Panels show the same specimens in different orientations: umbilical, spiral, and ventral views. Left side: light microscope and high-resolution color images showing pink to orangish-pink shell tint. Right side: scanning electron microscope (SEM) images highlighting surface texture and chamber structure.

Map of the Bay of Bengal and Arabian Sea showing sea surface salinity in winter (left panel) and summer (right panel). Core site MGS30 is marked with a star in the eastern Bay of Bengal, with additional sites U1457, U1446, MD77, and RVS2 labeled. Seasonal arrows show East India Coastal Current (EICC) and West India Coastal Current (WICC) flow directions. Color shading indicates salinity, with fresher water in blue and saltier water in yellow.

Detailed programme 👇🏼

Pretty cool, right? Can you think of other shell features or clues that could serve as proxies? Share your ideas in the comments!

Fossil - Japanese Star Sand Fossil star sand from Japan – microscopic sea creatures in the shape of tiny stars. A unique and beautiful piece of natural history in miniature.

Fossils, myths, and tiny stars.

This “sand” from Okinawa is made of marine microfossils shaped like stars – loved by both scientists and storytellers.
A magical gift for the curious.
