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.
The purpose of this experiment, performed as part of the McMurdo Dry Valleys Long Term Ecological Research (MCM LTER) program, was to investigate the impact of lake level rise and moat expansion on microbial community diversity and function in the East Lobe of Lake Bonney, located in Taylor Valley, Antarctica. The “tLICE” experiment tested the following MCM5 Hypotheses: H3-Disturbance increases connectivity and accelerates shifts towards homogeneity, and H4-Decreased heterogeneity reduces community resistance and resilience.
