Hydrothermal plume dispersion model outputs for the Endeavour Segment of the Juan de Fuca Ridge for the years 2016, 2021, and 2023

This dataset contains model output files from numerical simulations of hydrothermal plume dispersion at the Endeavour Segment of the Juan de Fuca Ridge, spanning two one-year periods in 2016 and 2021, as well as a 2.5-month period from mid-July to late September 2023. The simulations capture the complex interactions among seafloor hydrothermal discharge, deep-sea ocean currents, and mid-ocean ridge topography, and they illustrate the dispersion of hydrothermal plumes from the ridge segment into the surrounding ocean interior. Furthermore, the 2023 simulation was conducted in support of the research expedition AT50-15 to the Endeavour Segment in September 2023. Its outputs were used to guide at-sea autonomous underwater vehicle (AUV) surveys of hydrothermal plumes during the cruise. Following the expedition, the simulation was refined to improve its fidelity and the updated outputs were used to inform analysis of plume biogeochemistry. The model output files included in this repository are from the post-cruise refined simulation. All simulations were conducted using the Regional Ocean Modeling System (ROMS). The outputs, provided in NetCDF format, include three-dimensional fields of velocity, temperature, and salinity, along with additional model variables.
