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). -117.0131667 -117.01245 11.86268333 11.86436667 -117.01290334000001 11.863263333999999 2019-04-12T10:51:48 2019-05-16T10:39:25 not specified 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 5 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ Station label | Station | Area/locality | Area | Core | ex-situ | Oxygen | O2 | Amperometric Clark-type oxygen microelectrode, Unisense, Denmark citable Anthropogenic disturbances Clarion Clipperton Fracture Zone deep sea mining deep sea sediment Geochemical data method14508 param102005 param15373 param48492 param754 pi66739 author10649 author34470 author61745 author66739 author671 author83967 award352 funder20473 geocode1599 geocode1600 geocode1601 inst20147 inst32 license21 project4206 project4275 term49772 term51350 term54071 term67507 term69997 topotype1
