| Summary: | Abiotic parameters were collected at 21 sites across two coordinated sampling efforts. In the first set of samples (summerlong set), data were collected from 29 April through 22 August 2017, where each site was visited once during that time frame. Data from this effort include seawater temperature (C), salinity (ppt), dissolved oxygen (mg per L), light (umol per meter squared), and nutrients (umol; nitrate + nitrite, ammonium, phosphate). In the second sampling effort, data were only collected on 14 August 2017 but all 21 sites were visited within an 8-hr time frame using two independently operating boats. Data from this effort include seawater temperature (C), salinity (ppt), dissolved oxygen (mg per L) for some sites, and nutrients (umol; nitrate + nitrite, ammonium, phosphate); light data were not collected. Site name, coordinates, sampling time, sampling dates, and sampled depths for each site are included in the data file for each data point. The purpose of these data was to characterize the fish assemblage within eelgrass communities so that analysis of trophic interactions could be assessed along a gradient of sea otter occupation for an NSF-funded project: Apex Predators, Ecosystems, and Community Sustainability (APECS, http://apecs-ak.org/). Other datasets to support this work are also archived with KNB.
