These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program, nearshore monitoring component. The dataset has one comma separated values (.csv) table with estimates of eelgrass (Zostera marina) percent cover. Eelgrass cover was estimated from sonar and video drop cameras deployed from boats following prescribed survey transects.

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program, nearshore monitoring component. The dataset is comprised of six comma separated values (.csv) file exported from a relational database. The data consist of 1) summer marine bird and mammal densities, 2) winter marine bird and mammal densities, 3) summer marine bird and mammal observations, 4) winter marine bird and mammal observations, 5) summer marine bird and mammal survey strip transects, and 6) winter marine bird and mammal survey strip transects.

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and describe bivalve count and size sampling and observations conducted at intertidal soft-sediment sampling sites in the northern Gulf of Alaska. This dataset consists of five comma separated files (.csv): 1) bivalve taxonomy table, 2) bivalve sampling site table, 3) bivalve count table, 4) bivalve size table, and 5) list of Gulf Watch Alaska principal investigators and collaborators.

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program, nearshore monitoring component. The dataset is comprised of six comma separated values (.csv) file exported from a relational database. The data consist of: 1) transect summary, 2) nest details, 3) egg float and stage data, 4) chicks diets, 5) chick diet taxonomy, and 6) Gulf Watch Alaska contributors. Version History: First release: April 2017 Revised: November 2023 (ver. 2.0)
These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program. This dataset consists of date, time, and temperature measurements from intertidal rocky sampling sites, including predicted tide height at the time of the reading, which is used to distinguish air from water temperature readings. The data are provided as comma separated values (.csv) files derived from data downloaded from HOBO temperature loggers. This dataset includes previously released data and supersedes the USGS data release (https://doi.org/10.5066/F77S7KXH).

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program. This dataset consists of observations of sea otter (Enhydra lutris) fecal samples (spraint). Observers examined fresh spraint piles to identify major prey classes in the samples and to determine sea otter diets in the Gulf of Alaska region.
