Description:
The deployment of LOOME was performed by lowering the LOOME frame by winch, followed by positioning of the surface sensors across the most active site by ROV. The frame was placed on an inactive slab of hydrates, eastwards and adjacent to the hot spot. As part of the LOOME-frame Sun & Sea multi parameter probe CTD 60M was deployed approximately 3 m above the seafloor. The device was rated to 2000 m water depth. As energy supply a DeepSea Power & Light SeaBattery (12V) was used, which allows a run time of the CTD 60M of more than a year. The memory capacity of the probe is sufficient to allow data storage for more than a year as well, applying a time resolution of better than one measurement per minute. The probe was configured to start running when the energy supply is connected and a magnetic switch is closed. An LED on top of CTD is indicating the current state of the probe. The major aim was to record the temperature and pressure regime in the bottom water at the Håkon Mosby Mud Volcano.
