During the 95/96 Austral summer, the depth of the Lake Hoare and Lake Fryxell was measured at several points and dates using a piezometer. Lake Joyce and the West Lake Bonney's depth were also measured using this instrument at one location.

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been undertaken to monitor the abundance and species distribution of algal mats in glacial meltwater streams of the region. This data set includes results from light and dark incubations of algae to calculate net and gross primary productivity versus light curves of algal communities from Green Creek in Fryxell basin during January 1995. This data set constitutes the LTER algal primary productivity data for streams.

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, water was diverted to a relict stream channel in order to reactivate the streamflow. The purpose of this experiment was to quantify the time scales of response to the arrival of water after many years of dessication. This table contains data showing the ash-free dry mass represented by algal type (brown-colored, red-colored, orange-colored, or green-colored, filamentous, sand, rock or moss) and incubation type (light, dark, or none) for the Relict Channel in the Fryxell basin.

The purpose of this experiment was to quantify the time scales of response to the arrival of water after many years of dessication. This table contains data showing the chlorophyll, carbon, nitrogen, and hydrogen concentrations of algal communities and some mosses from the relict channel.

As part of the McMurdo Dry Valleys Long Term Ecological Research program, meteorological data are collected from various locations throughout the McMurdo Dry Valleys of Antarctica. This package contains monthly measurement summaries derived from 15-minute data generated by the Explorers Cove Meteorological Station (EXEM), located in Taylor Valley (Latitude: -77.588733, Longitude: 163.417523, Elevation: 25 meters above sea level). EXEM was acquired from USGS in 1997, during the 97/98 field season.

As part of the new Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic aqueous geochemical sampling program has been undertaken. A series of terrestrial water samples have been collected and analyzed for major ion chemistry by ion chromatography. The concentrations of ions cover a wide range of total dissolved solids (TDS) from relatively pristine glacier ice to hypersaline lake waters.

As part of an ongoing long-term sampling effort conducted by the McMurdo Dry Valleys Long Term Ecological Research (LTER) project, the top 10 cm of soil was collected from sampling sites across the McMurdo Dry Valleys region of Antarctica. A subset of these samples representing each valley and a differing disturbance legacy from the last glacial maximum were analyzed for this data package. Samples were collected between 1995 and 2022.

Concerns over environmental disturbance in the McMurdo Dry Valleys are increasing with increasing foot traffic from tourists and scientist. The effect of pedestrian disturbance was monitored by comparing the species composition, depth distribution and soil properties between adjacent high-, low- and no- traffic sites. This study began in the austral summer 1995/1996.

In the Antarctic Dry Valleys, soil polygons are prominent features of the landscape and may be key units for scaling local ecological information to the greater region. We examined polygon soils in each of the 3 basins of Taylor Valley, Antarctica. Our objectives were to characterize variability in soil biogeochemistry and biodiversity at local to regional scales, and to test the influence of soil properties upon invertebrate communities.
