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
