    AbstractBathymetry based on data recorded during M72-1 between 07.02.2007 and 20.02.2007 in the Black Sea. The main focus of the cruise were gas vents and seeps in the north-western Black Sea below 700 m water depth which is the zone of gas hydrate stability. The main target area was the deep Dniepr Canyon west of the Crimea Peninsula where previous investigations had indicated the occurrence of gas seepage. CI Citation: Chris dos Santos Ferreira (seafloor-imaging@marum.de): Owner of the end grid. Paul Wintersteller (seafloor-imaging@marum.de): Responsible party for bathymetry post-processing and author of the product. Detailed description: During the cruise M72-1 the Kongsberg EM120 multi-beam-echo sounder was used. The EM120 uses a nominal sounding frequency of 12 kHz. 191 beams with a 1°/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 . The EM120 was used mainly in order to detect, localize and quantify methane fluxes at cold seeps in major investigated areas.

    QI_Lineage2015-07-16Description 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 suite (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 difference of less than 20 cm in the Black Sea. Further roll, pitch, heave and sound velocity corrections were not applied for the M72-1 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 70 m. 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 archive (dos Santos Ferreira, Christian; Wintersteller, Paul (2016): Gridded bathymetry from multibeam echosounder EM120 data of the cruise M72/1 (2007) [dataset]. PANGAEA, https://doi.org/10.1594/PANGAEA.860081).
