Dissolved lead and manganese in the western Bering Sea

This repository contains data on dissolved lead and manganese distributions in the western Bering Sea, collected during the Mu-18 cruise onboard R/V Professor Multanovskiy between August and October 2018. Sampling was carried out along 5 transects (B, C, E, F, and CN lines). Sample collection was carried out using acid-clean Teflon-coated 12 L X-Niskin bottles, which were mounted onto a modified clean conductivity-temperature-depth carousel (Nishioka et al., 2021). The maximum sampling depth was 3000 m. The dissolved fraction was obtained through filtration through a 0.2 µm pore-size capsule filter (Acropak, Pall Industries) immediately after sample collection. Samples were acidified (pH < 2) for storage. Dissolved Mn and Pb concentrations in the samples were analyzed by high resolution inductively coupled plasma mass spectrometry following a pre-concentration step using a NOBIAS PA-1 chelating resin column (Kondo et al., 2016; Wong et al., 2021).  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.
