Summary: The Oxford Lake-Level Data Bank comprises records of lake status, a measure of relative water depth, for lake basins which
have been closed for part, or all, of their Late Quaternary history. The data base is arranged regionally in the following
order: Africa; South and Southwest Asia (including Afghanistan
and India); China; Soviet Union; North America (U.S.A. and Canada, in that
order); Mexico; South and Central America; Australasia (Australia, New Zealand and Papua
New Guinea, in that order); Europe and Greenland. Within each regional block the order of the basins is alphabetical.
For North America, basins are listed alphabetically by state or province. The full data bank is stored, in slightly different
formats, in the files LAKEDATA.DAT and LAKERES.DAT. These files contain the lake status and trend codes, with information
about supporting radiocarbon dates for each 1000-year time slice for each basin. Each basin is uniquely identified by a COHMAP
Basin number, called the Brown Master Number (BMN) (see Appendix C). This number permits quick reference to be made between
the full data bank and supporting files (Appendices C, D and E). LAKERES.DAT contains headings to help the reader understand
the data. However, LAKEDATA.DAT contains the raw data without descriptive headings. Therefore, its format is described below.
