High-frequency, hourly, and daily measurements from the East Lake Bonney "Blue Box" (ELBBB), McMurdo Dry Valleys, Antarctica (1994-2024, ongoing)
As part of the McMurdo Dry Valleys Long Term Ecological Research program, continuous measurements have been collected from a network of automated lake monitoring platforms in the McMurdo Dry Valleys of Antarctica. These lake-based stations, commonly referred to as “blue boxes” due to their historically blue instrument enclosures, provide high-frequency observations of key limnological variables essential for understanding physical drivers of aquatic ecosystem dynamics in the perennially ice-covered, meromictic lakes of this polar desert environment. This data package includes measurements from the East Lake Bonney “blue box” lake monitoring platform (ELBBB), established during the 1994-1995 austral summer in East Lake Bonney, Taylor Valley. Parameters include air and water temperature, surface and underwater photosynthetically active radiation (PAR), continuous stage (lake level), ice surface ablation, and, beginning in the 2022-2023 austral summer, dissolved oxygen (DO), reported as percent saturation due to the unavailability of continuous salinity measurements required for computing concentration. Data are provided at high frequency (typically 15-minute intervals), along with hourly and daily summaries. Users should note that summary statistics may be affected by periods of missing data. As there is no universally accepted standard for handling gaps in time-series data, users are encouraged to use the high-frequency data and establish their own criteria for acceptable data completeness to minimize potential bias.
Soil Lake Inundation Moat Experiment (SLIME): Continuous environmental measurements from the North Shore East Lake Bonney (NELB) Active Layer and Moat Monitoring Station (ALMMS), McMurdo Dry Valleys, Antarctica (2018-2022, ongoing)
The Soil Lake Inundation Moat Experiment (SLIME) was developed by the McMurdo Valleys LTER project to investigate the ecological function of lake moats in Antarctica. These moats form during the austral summer when the edges of permanently ice-covered, closed-basin lakes melt, creating open-water zones, or ‘moats,’ between the shoreline and the thick (3-5 m) perennial ice cover. Extensive microbial mats are found across these moatbeds, yet their ecological dynamics remain poorly understood. To study these habitats, we established sampling transects on the north and south shores of Lake Fryxell and the East Lobe of Lake Bonney. At each transect, we manually sample soils, sediments, microbial mats, and the water column during the austral summer. To complement these efforts, Active Layer and Moat Monitoring Stations (ALMMS) continuously measure key environmental variables, including moatbed temperatures, incoming and underwater photosynthetically active radiation (PAR and UW-PAR), subsurface temperatures, soil volumetric water content, and soil electrical conductivity across a moisture gradient from wet (near the lake shore) to dry (further inland). These measurements help us understand environmental and ecological changes as shoreline soils transition between aquatic and terrestrial habitats, whether through inundation from rising lake levels or drying as moatbeds are exposed. The North Shore East Lake Bonney SLIME transect is located approximately 2000 m west of the Priscu Stream inflow to the East Lobe of Lake Bonney. Sensor deployments along the transect follow a wet-to-dry gradient, capturing environmental transitions in real time.

McMurdo Dry Valleys site, station East Lake Bonney, study of calcium in lake water in units of milligramsPerLiter on a yearly timescale
The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from McMurdo Dry Valleys (MCM) contains calcium in lake water measurements in milligramsPerLiter units and were aggregated to a yearly timescale.
