As part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project, ice thickness and density are measured annually for several lakes located throughout this region of Antarctica. Ice thickness is measured from the bottom of the ice cover to the piezometric water level and to the top of the ice cover. Because most limnological sampling holes are drilled in low-lying areas, it was thought that ice thickness measurements were biased. Therefore, random ice thickness measurements were performed in a 1000 m2 sampling grid on each lake in past years.
Dataset Results
Manual lake level surveys are conducted each season for several lakes across the McMurdo Dry Valleys of Antarctica. This data package 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.

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a series of Taylor Valley lakes have been monitored for conductivity, temperature, and depth (CTD). A Seabird instrument was used to record CTD profiles in these perennial ice covered lakes.

This data set includes the deployment of anchored thermistors Lake Vanda, Wright Valley, as part of an Antarctica New Zealand project. Thermistors were positioned at the sediment-water interface and 10 cm above the lake bottom within the thermocline at 24 m depth.
