Lake level surveys in the McMurdo Dry Valleys, Antarctica from 1991 to present

Summary

Abstract: 

Manual lake level surveys are conducted each season for several lakes across the McMurdo Dry Valleys of Antarctica. This dataset includes lake levels for Lake Fryxell, Lake Hoare, and Lake Bonney, located in Taylor Valley; Lake Vanda and Don Juan Pond, located in Wright Valley; Lake Vida, located in Victoria Valley; Lake Miers, located in Miers Valley; and Lake House and Lake Joyce, located in Pearse Valley.

Variables (click to expand): 

DATASET_CODE
  • Label:
  • Definition: Code that identifies the table in the database. LIMNO_LAKE_LEVELS, in this case.
  • Type: Nominal
  • Missing values: None specified
LAKE
  • Label: Lake
  • Definition: Name of lake where measurement was made
  • Type: Nominal
  • Missing values: None specified
DATE_TIME
  • Label: Date
  • Definition: Date on which measurement was made
  • Type: Date/time
  • Date format: mm/dd/yyyy
  • Missing values: None specified
REFERENCE BENCHMARK
  • Label: Reference Benchmark
  • Definition: This is the old benchmark used for lake leveling that the new measurements are corrected to
  • Type: Nominal
  • Missing values: None specified
SURVEYING BENCHMARK
  • Label: Survey Benchmark
  • Definition: This is the benchmark the optical survey was actually performed on. The lake level below this datum is recorded with level and stadia rod
  • Type: Nominal
  • Missing values: None specified
LAKE LEVEL(masl)
  • Label: Lake Level (masl)
  • Definition: Lake level below datum is expressed as meters above sea level (masl) in terms of the reference benchmark.
  • Type: Physical quantity
  • Unit: meter
  • Maximum: Not specified
  • Minimum: Not specified
  • Precision: Not specified
  • Missing values:
    • Required entry = None given
COMMENTS
  • Label: Comments
  • Definition: usually lists the surveyors. All measurements are made to true water level in drilled holes or in a connected moat. Some are shot to the surface of the moat ice and if so, that is noted here (rare)
  • Type: Nominal
  • Missing values: None specified
