Schematics of the upwelling circulation in submarine canyons

Submarine canyons are incisions of the continental slope that favor exchange of coastal and abyssal waters. Brun et al., present new work from the Cassidaigne canyon showing its key role for vertical exchange in the Mediterranean 🌊

A surface drifter floating in the blue sea. The drifter is a wood and fabric construction, mostly white, with 4 yellow buoys and an emerged case with a white box and a red light on top.

ok, this is maybe a long shot, but anyone here using GPS tags (the ones you can put in luggage etc) for self-built surface drifters? 🌊 So far we've used raspberry-pi with a GPS module, but we have lots of connection problems, so we're looking to simplify this....

Depth-time sections from Seaglider data

Episodic events, such as swirling water from eddies, fronts, and strong winds, can transport large amounts of organic carbon into deeper waters on short timescales. Kheireddine et al., deploy gliders to study these events in the Red Sea 🌊

A visualization of a hydrothermal vent plume

Hydrothermal vent fields on the ocean floor release hot, mineral-rich water that forms rising plumes, known as black smokers. Lemaréchal et al., use computer simulations to investigate plume behavior near the seafloor 🌊
