This is the YKD egg observation data summarized into yearly stats on mean initiation and hatch dates for various species. This file is produced from the R code eggs.R.

This is the quality controlled YKD salinity data for fixed and random plots 2006 - 2019. These data are quality controlled using the R code in the file 'YKDsalinity_QC.R' to produce the data used for analysis and sharing ('YKDsalinity_QC.R'). These data should be what is used for analysis or distributed on request.

The daily boat tracks of the 2000-2002 winter skiff-based double-sampling surveys were recorded to an onboard computer using the custom survey software RECORD (John I. Hodges, FWS-MBM-Alaska, retired). The tracks were recorded by capturing the skiff’s location from a GPS every five seconds as long as the software was running. The software was started at some time between the boat’s engine start and the start of the survey, and was shut down at some time between the end of the survey and engine shut-down. The tracks may thus include the boat’s travel to and from the home base. Note that the 2001 boat tracks are missing.

The Alaska Swan Survey Protocol was first produced by MBM-AK sometime in the 1980s to describe a standardized method of conducting aerial swan surveys in Alaska. It was last updated in 2007. The protocol was not exclusive to the statewide Alaska Trumpeter Swan Surveys described in these metadata; however, it did generally describe these surveys’ flying technique and data collection methods.

The Alaska Trumpeter Swan Survey was an aerial survey conducted by the U.S. Fish and Wildlife Service, Division of Migratory Bird Management, Alaska Region (MBM-AK) and partners to monitor the status of trumpeter swans (Cygnus buccinator) in Alaska. It was first conducted in 1968 and then repeated at five-year intervals from 1975 through 2015. The objectives of the survey were to estimate the abundance, distribution (1968–2005 only), and productivity of trumpeter swans in late summer, when the swans were dispersed on breeding territories and cygnets were large enough to be easily counted from the air. Estimates were obtained for the abundance of white swans (swans >1 year old), cygnets, and total swans, as well...
