Wefer Gerold gwefer@marum.de 0000-0002-6803-2020 2022 Multibeam bathymetry raw data (Atlas Hydrosweep DS 2 echo sounder entire dataset) of RV METEOR during cruise M46/4 dataset https://doi.org/10.1594/PANGAEA.943133 2022-04-07T11:31:41 Multibeam bathymetry raw data using the ship's own Atlas Hydrographic Hydrosweep DS 2 multibeam echo sounder was almost continuously recorded during RV METEOR cruise M46/4. Data was recorded on 27 days between 2000-02-11 and 2000-03-09. This dataset contains a transit survey in the Southern Atlantic Ocean . The approximate average depth of the entire dataset is around 6200m. The data are archived at the Federal Maritime and Hydrographic Agency of Germany (Bundesamt für Seeschifffahrt und Hydrographie, BSH) and provided to PANGAEA database for data curation and publication. No ancillary sound velocity profiles (SVP) files from the cruise are archived at the BSH, thus no SVP files are added to this dataset. This publication is conducted within the efforts of the German Marine Research Alliance in the core area 'Data management and Digitalization' (Deutsche Allianz Meeresforschung, DAM). Data are unprocessed and therefore contains incorrect depth measurements (artifacts) without further processing. Note that refraction errors can be expected due to the lack of proper SVP. Overall, it appears that the data quality is rather poor since the gridded hillshade data showed relatively many obstacles. Data can be processed e.g. with the open source software package MB-System (Caress, D. W., and D. N. Chayes, MB-System: Mapping the Seafloor, http://www.mbari.org/products/research-software/mb-system/, 2022). -52.0595 -12.22976667 -44.51681667 -27.9344 -26.205744770686277 -38.3016080062745 2000-02-11T11:51:07 2000-03-09T05:36:09 -15452.5283 -692.6869 uncoded table DAM_Underway DAM Underway Research Data https://www.allianz-meeresforschung.de/en/activities/data-management-and-digitalisation/underway-research-data DataHub DataHub Earth and Environment of the Helmholtz Association https://helmholtz.software/projects/datahub Bundesministerium für Bildung und Forschung BMBF https://www.bmftr.bund.de https://doi.org/10.13039/501100002347 03F0880E DAM-Unterwegsdaten; Vorhaben: Aufbereitung und Kuration von Bathymetrie-, Unterwegs- und Forschungsmissionsdaten, Mitarbeit am DAM-Portal https://foerderportal.bund.de/foekat/jsp/SucheAction.do?actionMode=view&fkz=03F0880E M46/4_0_Underway-1 -38.251 -52.059 2000-02-11T11:51:07 -38.311 -50.684 2000-02-11T17:50:57 M46/4 M46/4 Mar del Plata 2000-02-10T00:00:00 2000-02-10 Salvador, Brazil 2000-03-13T00:00:00 2000-03-13 Meteor (1986) https://en.wikipedia.org/wiki/RV_Meteor_(1986) DBBH 8411279 Wefer, Gerold Wefer, Gerold doi:10.2312/cr_m46 20000104 Meteor (1986) https://en.wikipedia.org/wiki/RV_Meteor_(1986) DBBH 8411279 Swath-mapping system Atlas Hydrosweep DS-2 hdl:10013/epic.38032.d001 Atlas Hydrographic {Teledyne Reson} Hydrosweep DS 2 multibeam echo sounder http://vocab.nerc.ac.uk/collection/L22/current/TOOL0910/ Hydroacoustic devices Event shows start/end point (date/time & coordinates) of first/last data record using Atlas Hydrographic Hydrosweep DS 2 multibeam echo sounder during cruise M46/4 1734 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ These data should not be used for navigational purposes.
