The scientific work during cruise SO268 was part of the second phase of the MiningImpact project (Environmental impacts and risks of deep-sea mining) and is designed to assess the environmental impacts of deep-sea mining of polymetallic nodules in the Clarion-Clipperton Zone (CCZ) in the Pacific Ocean. Ex-situ oxygen was determined onboard using amperometric Clark type oxygen microelectrodes (Unisense, DK). -117.01245 -117.01245 11.86321667 11.86321667 -117.01245 11.86321667 2019-05-12T04:47:29 2019-05-12T04:47:29 0.05 0.26 vertical profile JPIO-MiningImpact JPI Oceans - Ecological Aspects of Deep-Sea Mining https://miningimpact.geomar.de GEOMAR - Helmholtz Centre for Ocean Research Kiel GEOMAR http://www.geomar.de https://ror.org/02h2x0161 AWI_MarGeoChem Marine Geochemistry @ AWI https://www.awi.de/en/science/geosciences/marine-geochemistry.html Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Bremerhaven AWI https://www.awi.de/ https://ror.org/032e6b942 Federal Ministry of Education and Research BMBF https://www.bmbf.de/ https://doi.org/10.13039/501100002347 03F0812F JPI-O MiningImpact: Auswirkungen von Manganknollenbergbau auf biogeochemische Prozesse und die Ausbreitung von Stoffen in der Tiefsee https://foerderportal.bund.de/foekat/jsp/SucheAction.do?actionMode=view&fkz=03F0812F SO268/2_186-1 MUC-37 11.86321667 -117.01245 Clarion-Clipperton Fraction Zone, North East Pacific Ocean -4116.5 2019-05-12T04:47:29 SO268/2 SO268/2 Manzanillo, Mexico 2019-03-30T00:00:00 2019-03-30 Vancouver, Canada 2019-05-27T00:00:00 2019-05-27 Sonne_2 https://uol.de/icbm/forschungsplattformen-schiffe/sonne DBBE 9633927 Haeckel, Matthias Haeckel, Matthias doi:10.3289/GEOMAR_REP_NS_59_20 20190057 https://www.ldf.uni-hamburg.de/sonne/wochenberichte/wochenberichte-sonne/so267-2-268-3/expeditionsheft-so-267-2-268-3.pdf https://maps.geomar.de/mapgen_ds/maps/legMap?lang=en&render=true&leg=SO268/2 Sonne_2 https://uol.de/icbm/forschungsplattformen-schiffe/sonne DBBE 9633927 Multicorer with television TVMUC GER Dredge; Position USBL; TV-MUC 88 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ Station label Station Volz Jessica B jessica.volz@awi.de 0000-0002-7825-2174 Station Area/locality Area Area http://dbpedia.org/resource/Area Volz Jessica B jessica.volz@awi.de 0000-0002-7825-2174 Area Core Core Volz Jessica B jessica.volz@awi.de 0000-0002-7825-2174 Core DEPTH, sediment/rock Depth sed m depth http://purl.obolibrary.org/obo/PATO_0001595 sediment http://purl.obolibrary.org/obo/ENVO_00002007 rock Length L http://dbpedia.org/resource/Length Volz Jessica B jessica.volz@awi.de 0000-0002-7825-2174 Depth sed [m] Oxygen O2 µmol/l oxygen O https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:25805 Molar Concentration Amperometric Clark-type oxygen microelectrode, Unisense, Denmark Volz Jessica B jessica.volz@awi.de 0000-0002-7825-2174 ex-situ O2 [µmol/l] CurationLevelC Enhanced curation https://wiki.pangaea.de/wiki/Curation_levels citable Anthropogenic disturbances Clarion Clipperton Fracture Zone deep sea mining deep sea sediment Geochemical data author10649 author34470 author61745 author66739 author671 author83967 award352 basis5064 campaign3390190 campaign46192 curlevel30 event2913323 funder20473 geocode1 geocode1599 geocode1600 geocode1601 geocode8128 inst20147 inst32 license21 method11340 method14508 param102005 param15373 param48492 param754 pi66739 project4206 project4275 term1073131 term26027 term28162 term38263 term38494 term41056 term43770 term43863 term44030 term49772 term51350 term54071 term67507 term69997 term77594 topotype3
