This dataset, SummerSimplified.csv, contains the bird and marine mammal data collected during the 1997-2002 aerial summer Southeast Alaska Nearshore Waterbird Survey, edited for quality-control (QC) purposes. During the QC process, observations of the same species that were less than 0.3 nautical miles apart were merged. Species codes of certain species were changed to a group code, e.g., scoter-specific species (BLSC, SUSC, WWSC) to SCOT. Species that were considered inadequately surveyed due to detection issues or inappropriateness of the survey design were removed.
