Abstract submission is open for #EGU26 (3 - 8 May 2026) 🚨 Are you working with #microfossils and have a story to tell about the #paleoenvironment and/or #paleoclimate? Then join our session to put a focus lens on these amazing micropaleontological proxies!
Show PostAgglutinated forams (forams that make their shells by adding or agglutinating sorrounding stuff) make their shells by gluing things they find around them: sand, minerals, and skeletons of other organisms! This includes other forams, sponge spicules, even radiolaria! 😱😱
Show PostIn the deep ocean, density differences drive thermohaline circulation as ocean layers have different temperature & salt content. In the shallower ocean, winds also drive circulation & supply oxygen! Today, areas with little oxygen (Oxygen Minimum Zones-OMZ) form where subsurface circulation is slow
