Short summary
Short summary
Understanding past iceberg activity during the Quaternary is key to constraining ice‑sheet dynamics and freshwater release during melting. We document ice‑rafted dropstones dredged at 36° N on the Mid‑Atlantic Ridge that form a calc‑alkaline magmatic series and yield ages of ~1700–1630 Ma. This indicates derivation from the Labradorian arc‑accretion orogeny in eastern Canada, implying a source in the Gulf of Saint Lawrence that favored southward iceberg transport to lower latitudes.

Short summary
Short summary
We use the Minerve virtual reality software to bring undergraduate students to an unusual field trip at 1200 m below sea level in the Lesser Antilles area. This region is located above an active subduction zone responsible for intense volcanic and seismic activity. In particular, we focus on the Roseau submarine fault that ruptured during the Mw 6.3 Les Saintes earthquake and presented a fresh scarp that the students can analyze and map in VR. They compile their results in a GIS project.

Short summary
Sediments accumulated in accretionary prisms are deformed by the compression imposed by plate subduction. Here we show that deformation of the sediments transforms some minerals in them. We suggest that these mineral transformations are due to the proliferation of microorganisms boosted by deformation. Deformation-enhanced microbial proliferation may change our view of sedimentary and tectonic processes in subduction zones.
