These data are in three folders of Keyhole Markup Language (KML) geospatial polygons representing the outlines of walrus herds apparent in satellite imagery. Each KML file contains one or more geospatial polygons of walrus herd outlines created by one observer who visually interpreted the images. The attribute values from all KML files are collected in a CSV table included with this data package. Additional walrus satellite image-derived Chukchi Sea walrus haulout outlines are available in another USGS data release (Fischbach and Douglas 2022; https://doi.org/10.5066/P9CSM0KN)
