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.
Dataset Results
This data set includes the deployment of an anchored pressure transducer and suspended thermistor string in Lake Joyce, Pearse Valley, as part of a NASA Astrobiology: Exobiology and Evolutionary Biology project. Instruments were deployed prior to summer melt in December 2014 near a melt water stream and retrieved in December 2015. Thermistors were positioned in the fresh water lens under the ice cover, within the water column, and on the lake bottom.

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.

As part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project, we investigated relationships between wind conditions and barotropic seiches within Lake Hoare, located in Taylor Valley, Antarctica, during the 2012-2013 austral summer. Temporal changes in the water column were measured using a rugged, handheld, CastAway CTD (conductivity-temperature-depth probe, manufactured by SonTek), deployed through the Lake Hoare Limno Hole (note, this is a separate instrument from the SeaBird CTD used as part of the MCM LTER core limnological monitoring program).
