Lake ice thickness and density measurements, McMurdo Dry Valleys, Antarctica (1989-2025, ongoing)
As part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project, ice thickness and density are measured annually for several lakes located throughout this region of Antarctica. Ice thickness is measured from the bottom of the ice cover to the piezometric water level and to the top of the ice cover. Because most limnological sampling holes are drilled in low-lying areas, it was thought that ice thickness measurements were biased. Therefore, random ice thickness measurements were performed in a 1000 m2 sampling grid on each lake in past years. Statistical analyses by Dr. Priscu have shown that measurements from three ice holes are representative of the ice thickness measured by this grid system.
High-frequency, hourly, and daily UV measurements from Lake Hoare Meteorological Station (HOEM), McMurdo Dry Valleys, Antarctica (2015-2022, ongoing)
As part of the McMurdo Dry Valleys Long-Term Ecological Research program, total ultraviolet (UV) irradiance has been measured since 2015 using an independent UV radiometer system co-located with the Lake Hoare Meteorological Station (HOEM) in Taylor Valley, McMurdo Dry Valleys, Antarctica. Data are provided at high frequency (5-minute intervals), along with hourly and daily summaries. Users should note that summary statistics may be affected by periods of missing data. Since there is no universally accepted standard for handling gaps in time-series data, users are encouraged to work with the high-frequency data and establish their own criteria for acceptable data completeness to minimize any potential bias.
