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 dissolved oxygen and temperature profiles. A YSI dissolved oxygen meter was used to record these measurements in the perennial ice-covered lakes of Taylor Valley. The measurements were collected from 1993 to 2000. Other methodologies to monitor temperatures and dissolved oxygen in lakes are being used.

A YSI Model 58 meter with a YSI 5739 probe was used to record temperature and dissolved oxygen profiles. Calibration of the meter and probe was performed in water saturated air, near 0 degrees C, with the salinity correction set to 0 ppt. All measurements were recorded with the same salinity correction (0 ppt). The probe was manually agitated by slowlay moving in an up and down motion (~2 cm). Once the probe stabilized, the data was recorded.
