High-resolution record of surface seawater carbon dioxide (CO2) content, water temperature, sea surface salinity and other parameters collected in Sitka Harbor, Alaska, USA from 2017-06-01 to 2021-04-27 (NCEI Accession 0247208)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 04:03 AM | Dataset Last Updated: February 11, 2022 at 12:00 AM
This dataset includes measurements of partial pressure of carbon dioxide (pCO2), sea surface salinity, sea surface temperature and other parameters collected in Sitka Harbor, Alaska, USA from 2017-06-01 to 2021-04-27. Sitka Tribe of Alaska’s Environmental Research Laboratory adjacent to Sitka Harbor, has been a site for shore-based and high-resolution measurement of surface seawater CO2 content since June 2017. Temperature, salinity, and CO2 partial pressure measurements are made near-continuously from a seawater sample line with an intake 50 m from shore and at a depth of 1 m in Sitka Harbor. The effort to collect these data is a collaboration between the Sitka Tribe of Alaska and the Hakai Institute with support from the Alaska Ocean Observing System
