The MARUM Camera System was developed by Dr. Yann Marcon, Professor Gerhard Bohrmann, and a team of engineers at the MARUM Center for Marine Environmental Sciences and the Department of Geosciences, University of Bremen, Germany. It was funded by the German Federal Ministry of Education and Research (BMBF) within the scope of the “M³: Monitoring Marine Methane” projects (grants 03F0765A and 03F0854A). The MARUM Camera System focuses on the Summit-A vent site at the summit of Southern Hydrate Ridge. It monitors the short-term variability of methane bubble plumes and changes in the seafloor morphology related to the venting activity.

The MARUM Camera System is a 4K camera with a LED lamp mounted on a pan-tilt unit on a 1.3 m-high tripod (Figure 1). The camera can record 4K videos and 21 MP photographs.

The MARUM Camera System was set to record 30-second 4K videos bihourly and three consecutive stills every 30 minutes.

Instrument Models & Deployed Locations

The MARUM Camera System was installed at the Summit-A vent site at the summit of Southern Hydrate Ridge at a water depth of 780 m. The instrument is connected to the medium-powered junction box MJ01B. It consists of a Rayfin Camera (SubC-Imaging), a Aquorea Mk3 LED lamp/strobe (SubC-Imaging), a titanium pan-tilt unit (Sidus Solutions SS120) and a titanium pressure vessel containing the on-board electronics. The instrument control and data collection scheduling is run remotely on a shore-side computer located at the Regional Cabled Array Operations Center, University of Washington.
