The chemistry of various glaciers (Canada, Commonwealth, Howard, Suess, Taylor) in Taylor Valley was measured for the following analytes between 1993 and 1997: Alkalinity, Ca, Cl, F, K, Mg, Na, NO3, Si, and SO4.
Dataset Results
The McMurdo Long Term Ecological Research (LTER) project monitors patterns of inorganic material transport in perennial ice-capped lakes. This data set addresses this core area of research and quantifies dissolved inorganic carbon concentrations at specific depths in McMurdo Dry Valley lakes. Dissolved inorganic carbon is also necessary for the computation of primary productivity.

As part of the McMurdo Long Term Ecological Research (LTER) project in the Dry Valleys of Antarctica, hydrogen ion concentrations were monitored in various lakes of the region. An Orion portable pH meter was used to record hydrogen ion concentrations at depth specific intervals in perennial ice-covered lakes.

An important part of the McMurdo Long Term Ecological Research (LTER) project is identifying patterns and movements of nutrients in perennial ice-covered lakes. This dataset addresses this core area of research and quantifies macronutrient concentrations (NH4+, NO3-, NO2, SRP) found at specific depths in McMurdo Dry Valley lakes.

As part of the 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 from the stream waters.

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 glacial meltwater streams in that region. This table contains macronutrient concentrations (nitrate, nitrite, ammonium, soluble reactive phosphorus) found at specific locations in McMurdo Dry Valley streams.

As a part of the McMurdo Dry Valleys LTER program, isotope ratios have been determined for 166 samples of stream water in Taylor Valley, Antarctica. Hydrogen/deuterium isotope ratios are given for all samples, and for a subset, there are oxygen isotope ratios, and a deuterium-excess. Values are reported relative to VSMOW, +/- 1.0 per mil for hydrogen, and +/- 0.1 for oxygen.
