Alaska Fisheries Science Center, National Oceanic and Atmospheric Administration. --doi:TBD, contact authors for updated citation details-- Aerial surveys of coastal Alaska are the primary method for estimating abundance of harbor seals. A particular challenge associated with aerial surveys of harbor seals is maintaining consistent spatial representation of haul-out locations (waypoints). In some cases, seals aggregate into a single large grouping at a particular area. In other cases, seals aggregate into several smaller groups spread over a particular area. To establish geo-spatial consistency, the Alaska Fisheries Science Center (AFSC) maintains a list of haul-out locations that represent known harbor seal aggregations in Alaska. Haul-out locations were identified through aerial survey efforts and historical knowledge. Locations are assigned a unique alphanumeric identifier, based on the survey unit they fall within, and the spatial data are provided in the geographic (epsg:4326) coordinate reference system. These haul-out locations are used to inform management decisions pertaining to coastal activities (presence/absence of seals in a particular area) and to facilitate AFSC field work that includes both aerial and vessel surveys. Haul-out locations are updated annually based on information obtained from aerial survey observations. This dataset contains Alaska harbor seal haul-out locations that are recorded primarily to support aerial survey efforts in August and (in some areas, June). Harbor seals are known to use various haul-out locations seasonally and, thus, this is likely not a complete collection of harbor seal haul-out locations. Some haul-outs that are close together may be combined and represented as one site or waypoint. Important haul-out locations have been identified in the "status" field of the attribute table and are labeled as "key haulout" if a particular location contains 50 or more harbors seals. A haul-out location containing less than 50 harbor seals is labeled "not key haulout". This number may change as more in depth analysis continues. This geospatial dataset describes observed haul-out locations used for coastal aerial surveys of harbor seals in Alaska. London, J.M., K.M. Yano, E.L. Richmond, D.E. Withrow, S.P. Dahle, J.K.

During aerial surveys, an observer photographs all haul-out locations within a given survey unit and is also responsible for recording any new haul-out location information that is observed. Survey unit boundaries were optimized to limit the number of known haul-out locations near the boundary. otherRestrictions otherRestrictions Access Constraints: no metadata access constraints | Use Constraints: Metadata are subject to revision at any time and information within the metadata record should not be cited without author consent.
