Notes

This folder contains maps showing bird distribution and abundance based on at-sea observations from February 1963 through August 1965 for the Pacific Ocean Biological Survey Program. Distribution and abundance data are represented by symbols, numbers, and colors added to printed maps of the central Pacific Ocean. Each map records data from one calendar month, with one map for each month of the year. No year information is shown on the maps, although an explanatory page in the folder says that the maps represent observational data from February 1963 through August 1965. Each map may therefore represent data collected during that month in one year or more than one year. Each symbol (square or circle) on the map represents one day's observations; symbols are color coded to represent number of birds per hour of observation. The map legends and explanatory sheet in the folder provide additional information on interpretation of the maps.
