Physical oceanography, current meter data, and microstructure measurements 180 km downstream of Denmark Strait sill during Maria S. Merian cruise MSM21/1b

The main objectives of the cruise MSM21/1b were to characterize the spatio-temporal variability of the Denmark Strait overflow and to identify processes responsible for the exchange of the overflow plume with ambient water downstream of Denmark Strait. A multi-platform approach was taken to achieve the goals, based on moorings, an autonomous underwater vehicle (AUV), as well as lowered and vessel-mounted observations. From these platforms, measurements of temperature, salinity, dissolved oxygen, current velocity, dissipation of turbulent kinetic energy, and bottom pressure were obtained.

Nematode abundance of the Eastern Mediterranean Sea in cold seep sediments collected during Maria S. Merain cruises MSM13/3 and MSM13/4 in 2009

Sediment was collected by either push cores operated by the ROV Quest or by a television guided Multicorer. Nematodes abundance were calculated of the top 5 cm of the sediment to gain individual abundance per 10 cm**2.
