Organic carbon burial in fjords of South Georgia

Despite their limited surface area, fjords play a disproportionately large role in the global organic carbon cycle. Those in the remote regions of the Southern Ocean are particularly poorly understood.

At the origin of cowries

Colombellinidae was a family of small marine snails that inhabited warm shallow seas during the Jurassic and earliest Cretaceous. This extinct group was revised based on all known fossils. The family included only two genera. Additionally, a new species from Bulgaria was described.

Antarctic Cretaceous and Paleogene crinoids

Research conducted on Seymour Island has shown that stalked crinoids continuously inhabited the shallow seas of Antarctica from the Late Cretaceous through the Paleogene.

Morphogenesis of the echinoderm diamond-type stereom

The echinoderm skeleton has a remarkable microstructure known as stereom. It is composed of calcitic trabeculae with curvatures close to “saddle-shaped” forms, characteristic of minimal surfaces, whose classical physical model is soap films stretched across wire frames, and whose mathematical example is the catenoid.

Coatings on shells from hydrothermal vents

Shells of marine gastropods from hydrothermal vent environments are coated with inorganic materials of unknown composition. Conversely, their fossil equivalents are known exclusively from outer moulds in pyrite (FeS₂), with no shell material left.

Methanogenic carbonates

Methane (CH₄) is largely built from the light carbon isotope (¹²C). When emitted from the seabed, methane is oxidized by sediment-dwelling microorganisms, with one of the byproducts being methanogenic carbonate cements, themselves with large amounts of the ¹²C.
