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 (μmol per meter squared), and nutrients (μmol; 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 (μmol; 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. These data were collected to compliment a study that investigated the influence of sea otters on the ecological interactions within and ecosystem services of seagrass habitats.
