This dataset contains current data acquired between july 2023 and august 2024 using 5 TCM-3 Ocean Bottom Tilt Current Meters installed next to the Tour Eiffel, hydrothermal vent site and near the SeaMon west station.
The TCM-3 Ocean Bottom Tilt Current Meter from Lowell Instruments LLC (North Falmouth, MA, USA) measures current using the drag-tilt principle. The logger is buoyant and is anchored to the bottom via a short flexible tether. Drag from moving water tilts the logger in the direction of flow. The logger’s accelerometer and magnetometer channels are used to record the amount of tilt and direction of tilt (compass bearing). The currentmeter's internal clocks are set to UTC time before deployment. Clock drift after recovery is not implemented in data but added as metadata in metadata file.
Data are provided for each deployed instrument as two text files:
- current data
- temperature data
