Details of CTDO Sections at the Udintsev Fracture Zone


Dataset identification

Title of datasetCTDO Sections at the Udintsev Fracture Zone
Narrative summary of datasetAs part of the ongoing PHANTOM (Poleward Heat Transport across the ACC) program of LOCEAN/Sorbonne University, we have recently occupied two full-depth Conductivity-Temperature-Depth (CTD) sections in the Udintsev Fracture Zone region during a current-meter mooring deploying cruise in February 2016 and a mooring recovery cruise in December 2017 on board the Korean icebreaker Araon, in collaboration with physical teams of Korea Polar Research Institute (KOPRI) and Korea Institute of Ocean Science and Technology (KIOST). Several hydrographic sections have been made in the upstream and downstream areas of the UFZ especially during the 1990s World Ocean Circulation Experiment (WOCE) period, such as WOCE P16 at 150°W and WOCE P17 at 135°W. However, no high-quality top-to-bottom hydrography has ever been performed in the UFZ itself at 144°W, despite its narrowest circumpolar choke point. Ref: Park et al. (2019), Observations of the Antarctic Circumpolar Current over the Udintsev Fracture Zone, the narrowest choke point in the Southern Ocean, JGR, in review. Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.
