Descritivo da Vaga:
Tipo de Atividade: Circulation of hydrothermal fluids through the oceanic crust at mid-ocean ridge (MOR) axes accounts for up to 10% of 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 sub-surface and the overlying ocean, and supports complex chemosynthetic ecosystems that are likely analogues for possible life in other parts of our solar system. The impact of hydrothermal circulation on each of the above processes or systems is directly linked to the magnitude and variability of volume, heat, and chemical fluxes exiting the seafloor, which are notoriously difficult to quantify. A first step toward characterizing those fluxes is to quantify exit-fluid vent velocities and volume fluxes. The analysis will consist mainly in estimating fluid flow velocities from high-resolution underwater videos using Particle Imagery Velocimetry theory and software (Davis LaVision), as well as working with plume theory and temperature data (Matlab or Python) among other tasks. The dataset spread over many different vent environments on the ridge system and covers almost a decade of monitoring. This part of the work involves some data mining and compilation, looking at deep-sea HD videos, and processing and analyzing chosen videos. A second step will be to study the dynamic behavior of those estimated black smoker velocities both in time and space and to compare results from different places across the Earth. This part will consist in interpreting and comparing different results from step one and carrying out time-space analysis on chosen cases. Finally, one could carry out an inversion of those results (velocities) -from PIV analysis- through plume modeling in order to estimate heat fluxes and therefore better constrain the total amount of heat lost by the planet at the ridge. This part consists in modeling a plume system (Matlab) and inverts previous results in order to obtain estimates on released heat.
