Thermistor Array Deployed for 1 Year

During VISIONS’13 ROPOS Dive R1636, the battery-powered version of the thermistor array was deployed at a small diffuse flow site at the base of the hydrothermal chimney called Mushroom. The thermistor array will provide a 3-dimensional view of the temperature structure at this site, which will help inform the community about the environmental conditions under which the biological assemblages thrive and evolve.

Deploying Thermistor Array

A 3D thermistor array designed by RSN Project Scientist Dr. Giora Proskurowski is deployed in the ASHES vent field for testing. A similar system will be deployed and powered up next summer, providing real-time 24/7 temperature data over the Internet for all to use/see. The blue cable holds 24 temperature sensors and was provided by RBR Ltd. The array will be placed in a diffuse flow site at the base of the vent called Mushroom, a site hosting abundant vent fauna. These data, coupled with seismic information, fluid chemistry, and HD imagery will be used to see how these systems evolve over time and how earthquakes influence chemical and biological processes.

Thermistor Array Ready for Testing

The 3D thermistor array designed by RCA Project Scientist Giora Proskurowski is attached to the Medium Powered J-BOx (MJ03B) in the ASHES hydrothermal field. The array will be tested on a follow-on dive, and in 2014 it will be deployed in a diffuse flow site at the base of the vent called Mushroom, along with a high-definition video camera and an osmo vent fluid sampler.
