Underwater photosynthetically active radiation (PAR) vertical profiles collected from lakes in the McMurdo Dry Valleys, Antarctica (1993-2023, ongoing)

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, lakes are monitored for photosynthetic active radiation (PAR) levels. This data set exemplifies the vertical profile of underwater PAR profiles in perennial ice covered lakes and ambient PAR measured at the air-ice interface. Profile data can be used to calculate extinction coefficients for the water column and ice layer.

Summer Phytoplankton Densities 1992-2001

Phytoplankton were collected over four austral summers (1991-92 through1994-95) to examine seasonal and annual fluctuation in species composition and biovolume in Lakes Fryxell, Hoare, West Lake Bonney, and East Lake Bonney. All of these lakes are perennially ice-covered lakes located in the Dry Valleys of South Victoria Land, Antarctica.

Summer vs Winter Phytoplankton Presence 1989-1991

Using automated overwinter sampling devices, we collected preserved phytoplankton samples from multiple depths in Lake Fryxell, a permanently ice-covered lake in southern Victoria Land, Antarctica. Photosynthetic algae were maintained in a stable water column throughout winter darkness. The algal taxa overwintered in different ways in a species-specific manner. Typical vegetative cells were the most abundant form for all species found in the water column. Populations of one chlorophyte, Stichococcus sp., were observed in winter, but the species was absent in both summers.

Winter Phytoplankton Densities during the 1990-1991 season

Using automated overwinter sampling devices, preserved phytoplankton samples were collected from multiple depths in Lake Fryxell, a permanently ice-covered lake in southern Victoria Land, Antarctica. Photosynthetic algae (i.e. algae possessing chloroplasts) are maintained in a stable water column throughout winter darkness. The algal taxa "overwinter" in different ways, in a species specific manner. Typical vegetative cells were the most abundant form for all species found in the water column.

Aeolian Distribution of Soil Biota from Airborn Sediment Traps

Dispersal of soil organisms is crucial for their spatial distribution and adaptation to the prevailing conditions of the Antarctic Dry Valleys. This study investigate the possibility of wind dispersal of soil invertebrates within the dry valleys. Soil invertebrates were evaluated in wind-transported dust particles in collection pans (Bundt pans) 100 cm above the soil surface. Three species of nematode were recovered and Scottnema lindsayae was the most dominant. There were more juveniles (71%) in the transported sediments than adults (29%).

The percent of anhydrobiotic nematodes with relation to soil moisture, temperature, and salinity was determined. The study began in the austral summer of 1996/1997. Locations: South side Lake Hoare and Fryxell, and moss site near Canada Glacier.

Soil wetting Effects on Anhydrobiosis of Nematodes

Investigation of the effect of short-term variation in soil moisture and soil temperature on nematode anhydrobiosis as part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project. The percent of anhydrobiotic (coiled) nematodes with relation to soil moisture and temperature was determined. The study began at 1030 on 10 December 1997 and ended on 11 December 1997. The samples were taken at 0, 6, 12, 18, and 24 hrs. Samples were collected in the south side of the Lake Hoare, Taylor Valley, Victoria lands, Antarctica
