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.
Dataset Results
During the 2017-2018 austral summer, a survey of soil invertebrate diversity and abundance was conducted throughout the Shackleton Glacier region of Antarctica to investigate whether habitat suitability, taxonomic diversity, and community composition follow predictable temporal patterns after the Last Glacial Maximum (LGM). Soil samples were collected along elevation transects from twelve ice-free areas to capture maximum variation in soil properties, geochemistry, and surface exposure age.

This data package consists of video footage of a rare rain event that occurred in the Fryxell and Hoare Basins of Taylor Valley, located in the McMurdo Dry Valleys region of Antarctica, on December 21, 2018. Footage was captured at 0600 NZDT at Lake Fryxell camp by Laura Smarrito, a Leidos contract carpenter. Permission was granted to publish this footage for the purposes of obtaining a DOI to properly cite this occurence in a scientific manuscript under revision by JE Barrett et al.
