MERIAN cruise MSM36 between 18.02.2014 and 17.03.2014 at the Moroccan continental margins. The cruise carried out multidisciplinary research on the long-term development of cold-water coral ecosystems in selected areas along the Moroccan continental margins in the Mediterranean Sea and in the Atlantic Ocean. The key instrument to be used during this expedition was the Bremen Deep Sea Drill Rig MeBo. CI Citation: Paul Wintersteller (seafloor-imaging@marum.de) as responsible party for bathymetry post-processing and its products. Description of processed data sources: During the RV MARIA S. MERIAN cruise MSM36 the moon pooled Kongsberg EM1002 shallow multi-beam echo-sounder was utilized. The EM1002 uses a nominal sounding frequency of 95 kHz. 111 beams are formed for each ping while the seafloor is detected using amplitude and phase information for each beam sounding. For further information consult http://www.tdi-bi.com/downloads/EM1002_Product_specification.pdf. The EM1002 delivered in general reliable data, problems during the acquisition only occurred during bad weather conditions. Responsible person during this cruise / PI: Stefanie Gaide (s.gaide@uni-bremen.de). Description of data processing: Postprocessing and products were conducted by the Seafloor-Imaging & Mapping group of MARUM/FB5, responsible person: Paul Wintersteller (seafloor-imaging@marum.de). The open source software MB-System suite (Caress, D.W., and D.N. Chayes, MB-System Version 5.5, open source software distributed from the MBARI and L-DEO web sites, 2000-2012.) was utilized for this purpose. A tide correction was applied, based on the Oregon State University (OSU) tidal prediction software (OTPS) that is retrievable through MB-System. CTD measurements taken during the MSM36 were sufficient to represent the changes in the sound velocity throughout the study area. Further tide, pitch and heave corrections were not applied for the MSM36 data. But a roll correction of -0.25° was applied (mbset). Bathymetric data has been manually cleaned for existing artefacts with mbeditviz. NetCDF (GMT) grids of the product and the statistics were created using mbgrid. No total propagated uncertainty (TPU) has been calculated to gather vertical or horizontal accuracy. The currently published bathymetric grid of the cruise has a resolution of 125 m. A higher resolution is, at least partly, achievable. A higher resolution is, at least partly, achievable. The grid extended with _num represents a raster dataset with the statistical number of beams/depths taken into account to create the depth of the cell. The extended _sd -grid contains the standard deviation for each cell. All grids produced are retrievable through the PANGAEA database (www.pangaea.de). Chief Scientist: D.
