Mapping operations were conducted today following cancellation of the remotely operated vehicle dive due to heavy seas. Here, Mapping Team Lead Meme Lobecker conducts an XBT, or expendably bathythermograph cast, to measure conductivity, temperature, and depth to 760 meters in order to calibrate the mapping data. Due to the high sea state and heavy winds, she is accompanied by a team member (Expedition Coordinator, Kelley Elliott) to ensure safe operations. They are watching the incredibly thin copper wire as it pays out from the XBT to ensure it doesn’t contact the ship and corrupt the data.

Mapping operations were conducted today following cancellation of the remotely operated vehicle dive due to heavy seas. Here, Mapping Team Lead Meme Lobecker conducts an XBT, or expendably bathythermograph cast, to measure temperature down to 760 meters in order to correct mapping data for water column variability. Due to the high sea state and heavy winds, she is accompanied by a team member (Expedition Coordinator, Kelley Elliott) to ensure safe operations. They are watching the incredibly thin copper wire as it pays out from the XBT to ensure it doesn’t contact the ship and corrupt the data.
