Distribution of thermochemical output and associated ecosystems at the Loki's Castle hydrothermal field

MSc project of Rasmus Rikter-Svendsen

Project title

Distribution of thermochemical output and associated ecosystems at the Loki's Castle hydrothermal field

Supervisors

Thibaut Barreyre, Eoghan Reeves

Project description

Circulation of hydrothermal fluids through the oceanic crust at mid-ocean ridges account for ~10% of the Earth's internal heat loss, controls the thermo-mechanical state and degree of hydration of newly formed oceanic lithosphere, plays a major role in solute transfer between the subsurface and the overlying ocean, and supports complex chemosynthetic ecosystems. The goal of the master project is to quantify the different types of hydothermal outflow at the Loki's Castle hydrothermal vent field using photomosaic imagery, and to constrain the heat-, mass- and chemical flux by integrating in-situ measurements.
