Womble J, Hoekman S, Ziomek T. 2024. Glacier Bay, Alaska murrelet survey detection function (KM_J) for survey year 2023. NPS Southeast Alaska I&M Network, Juneau, Alaska.
Program DISTANCE generates three output files for each year that are used for producing estimates of murrelet population status and trends. They are packaged together in a zip for downloading. The first file is named DFStats_yyyy.csv, which contains the estimates and related statistics used for Trend analyses and whose content is defined in Table SOP 11.3 of the protocol document. DFStats_status_yyyy.csv contains similar information, but is relevant to Status analysis. DFPlot_yyyy.png is a graphic depicting the detection function for a year, as illustrated in protocol Figure SOP 11.22. These data products have been compared against the formal quality criteria specified in the protocol in use at the time of product creation, found to be in complete compliance, and accepted by the program lead for public dissemination.
