Gridded bathymetry from multibeam echosounder EM120 data of the cruise MSM15/1 (2011)
Bathymetry based on data recorded during MSM15-1 between 12.04.2010 and 08.05.2010 in the Black Sea. The aim of this cruise was to quantify the concentration and uptake of oxygen at the anoxic boundaries in the water column and at the sediment water interface of the Black Sea, in parallel with the measurement of nitrogen, carbon, sulfur and iron fluxes (HYPOX project).

- Description of processed data sources
-
Description of processed data sources : During the cruise MSM15-1 the Kongsberg EM120 multi-beam echo sounder was used. The EM120 uses a nominal sounding frequency of 12 kHz. 191 beams with a 2°/2° footprint are formed for each ping while the seafloor is detected using amplitude and phase information for each beam sounding. For further information consult https://epic.awi.de/26725/1/Kon2007a.pdf
Three bathymetric datasets were surveyed during MSM15-1 with the EM120, while the main focus lay on the data acquisition with the shallow water multi-beam echo sounder EM1002. All surveys were run at a speed of 5 knots over ground. Responsible person during this cruise / PI: Sebastian Albrecht ( info@fielax.de ).
- Description of data processing
-
Description of data processing : Postprocessing and products were conducted by the Seafloor-Imaging group of MARUM, responsible person: Paul Wintersteller ( seafloor-imaging@marum.de ). The open source software MB-system (Caress, D.W., and D.N. Chayes, MB-System Version 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. In general, there is a tide differences of less than 20 cm in the Black Sea. Further roll, pitch, heave and SVP corrections were not applied for the MSM15-1 data. Bathymetric data has been manually cleaned for existing artefacts with mbeditviz. NetCDF (GMT) grids of the product and the statistics were created using mbgrid. Quality assurance was furthermore proven by visual and statistical comparison of crossing survey-lines from different cruises throughout the Black Sea. 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.
