Mooring data from Harrison Bay, Alaska, July-August 2021

Four small coastal moorings were deployed in water depths of ~5-6 meters (m) on the Colville Delta front and one site farther west for a period of approximately one week in Jul/Aug 2021. Moorings were outfitted with sensors to collect a variety of data including water levels (at all sites), turbidity/total suspended solids, water velocity, salinity, temperature, and light intensity. Light intensity measurements were also collected from a vessel-mounted sensor (included in the MM3 data package) to allow for calculation of light attenuation at the mooring. These data are described more fully in a companion publication (Eidam, "Summertime water and particle properties on an ice-influenced Arctic shelf", in prep as of March 2025).
