PI supplied instrument name: Alvin High Temperature Probe
Dataset-specific description

The high temperature probe has a type-K thermocouple located at the tip, with a tolerance of +/-3 up to 400 degrees C. To measure temperature profiles with this probe, the tip touched the sediment surface for the first reading before inserting the probe sequentially to desired depths and taking readings.
