Mixing Zephyr Program
Temperature Probes
Temperature is one of the most important parameters needed to
characterize the behavior of a hydrothermal system. The systems we use
for this purpose were designed and built in 1991 as part of the Flange
Fluid Fluxes program. They consist of a pressure housing containing a
Onset Computer Tattletale IV single board data logging computer,
necessary condition electronics, and a bank of 5 Ah lead-acid batteries
connected to an array of type K thermocouples. The array consists of
four thermocouples in a 1/8" o.d. Iconel sheath, arranged in two pairs of two
separated by ~4 cm. The thermocouple wires are connected to copper in a
molded junction which during deployment will be bathed in seawater. A
10 kohm thermistor is located at this junction so that the temperature
of the junction is known. The system is programmed to record
temperatures at a period appropriate to the memory available for data
storage and the length of deployment anticipated.
Deployments During the Mixing Zephyr Program
