MSM15/1 raw data of EM120 multibeam echosounder (bathymetry & beam time series)
Authors:
Boetius, Antje, Albrecht, Sebastian
Abstract:
Multibeam echosounder (MBES) data recorded during RV MARIA S. MERIAN cruise 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). CI Citation: Paul Wintersteller (seafloor-imaging@marum.de) as responsible party for bathymetry raw data ingest and approval. (...)
Multibeam echosounder (MBES) data recorded during RV MARIA S. MERIAN cruise 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). CI Citation: Paul Wintersteller (seafloor-imaging@marum.de) as responsible party for bathymetry raw data ingest and approval. Description of the data source: 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 about 5 knots over ground. Responsible person during this cruise / PI: Sebastian Albrecht (info@fielax.de). Chief Scientist: A.
