Midway Atoll Albatross Survey Sectors Three albatross species breed at Midway Atoll: black-footed (Phoebastria nigripes), Laysan (P. immutabilis), and short-tailed (P. albatrus). This dataset contains the boundaries of survey area sectors used during the USFWS albatross censuses at Midway Atoll National Wildlife Refuge. The entire area of the atoll is divided into 61 unequal-area sectors. Sector boundaries were established by the USFWS. USGS digitzed the sector boundaries using satellite imagery and data points collected during the 2011-2012 albatross breeding season (hatch year 2012).

As part of an effort to monitor albatross at this globally important site, USFWS personnel and volunteers conduct an annual, spatially-explicit, atoll-wide albatross census during the peak nesting when albatrosses are attending an egg (December-January). During the 2011-2012 breeding season (hatch year 2012) the census was conducted December 16, 2011–January 8, 2012. Albatross nest counts during the census were divided into 61 historically established, spatially-explicit sectors of unequal area. Within a sector, surveyors walked parallel transects approximately...
