This group of instruments was all deployed within a few meters of each other in a diffuse vent site near the black smoker "Easter Island".
Main Endeavour Field 6
Top Panel: Hourly values of temperature at the seafloor (red), velocity sensor ~0.5 m height (green), and near the top of the instrument stand ~1 m height (blue).
2nd Panel: 2-day running mean of temperature records.
3rd Panel: Hourly values of horizontal speed (colored) and the vertical component of velocity (black). Bottom Panel: 2-day running mean of horizontal speed and direction.

Main Endeavour Field 11
Top Panel: temperature at the seafloor (red), velocity sensor ~0.5 m height (green), and near the top of the instrument stand ~1 m height (blue). Middle panel: heat flux determined by direct correlation from ~2Hz vertical velocity and temperature data, averaged over 17 minute ensembles. Lower panel: horizontal current speed color-coded by direction and vertical velocity (black). All curves have been smoothed with a 10-ensemble running mean.
The record mean current at 0.5 m height is 2.8 cm/s directed toward 012°T, with friction velocity u* = 0.68 cm/s (Garcia-Berdeal 2006). The record mean heat flux is 4700 ± 660 W/m2 (Pruis 2004).
