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 nutrients for the Relict Channel in the Fryxell basin.
Dataset Results
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.

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.

This data package includes ecological parameters of biocrust and soil from samples collected in-situ within the Lake Fryxell Basin of the McMurdo Dry Valleys, Antarctica during December of 2019. Parameters include biological (ash-free dry mass, pigment concentration, and counts of soil invertebrates), physical (water content, electrical conductivity, and pH), and chemical properties (inorganic nitrogen, inorganic phosphorous, total nitrogen, and total organic carbon) of the surface soil, biocrust, and underlying soil.
