Dataset Overview | National Centers for Environmental Information (NCEI)

Surface underway measurements of pH, salinity and water temperature during R/V Xue Long CHINARE2018 Expedition (EXPOCODE 76XL20180723) in the Japan Sea, Sea of Okhotsk, North Pacific Ocean, Bering Sea, Chukchi Sea and Arctic Ocean from 2018-07-23 to 2018-09-22 (NCEI Accession 0233453)

Preview graphic

This dataset includes surface underway measurements of pH, salinity and water temperature obtained during R/V Xue Long CHINARE2018 Expedition (EXPOCODE 76XL20180723) Japan Sea, Sea of Okhotsk, North Pacific Ocean, Bering Sea, Chukchi Sea and Arctic Ocean from 2018-07-23 to 2018-09-22. The instrument used to measure pH data is an advanced spectrophotometric loop flow analyzer for high-precision seawater pH (LFA-pH). The pH data are calibrated with respect to discrete measurements of spectrophotometic pH during the cruise. The descriptions of data quality-control are given in a recently submitted manuscript to Geophysical Research Letters.
