Abstract

Datasets from a 4-year monitoring effort at Lake Peters, a glacier-fed lake in Arctic Alaska, are described and presented with accompanying methods, biases, and corrections. Three meteorological stations documented air temperature, relative humidity, and rainfall at different elevations in the Lake Peters watershed. Data from ablation stake stations on Chamberlin Glacier were used to quantify glacial melt, and measurements from two hydrological stations were used to reconstruct continuous discharge for the primary inflows to Lake Peters, Carnivore and Chamberlin creeks. The lake's thermal structure was monitored using a network of temperature sensors on moorings, the lake's water level was recorded using pressure sensors, and sedimentary inputs to the lake were documented by sediment traps. We demonstrate the utility of these datasets by examining a flood event in July 2015, though other uses include studying intra- and inter-annual trends in this weather-glacier-river-lake system, contextualizing interpretations of lake sediment cores, and providing background for modeling studies. All DOI-referenced datasets described in this paper are archived at the National Science Foundation Arctic Data Center at the following overview web page for the project: https://arcticdata.io/catalog/view/urn:uuid:df1eace5-4dd7-4517-a985-e4113c631044 (last access: 13 October 2019; Kaufman et al., 2019f).

Datasets from the Lake Peters watershed were collected with the help of numerous field assistants, including Zak Armacost, Mindy Bell, Ashley Brown, Anne Gädeke, Jeff Gutierrez, Rebecca Harris, Stacy Kish, Lisa Koeneman, Anna Lil-jedahl, Maryann Ramos, Doug Steen, and Ethan Yackulic. Sedimentary grain-size data were processed with assistance from Daniel Cameron and Katherine Whitacre. Water isotope analyses were performed with assistance from Jamie Brown at NAU’s Colorado Plateau Stable Isotope Facility, and major cation and anion analyses were performed by Tom Douglas of the U.S. Army Cold Regions Research and Engineering Laboratory. We thank the U.S. Fish and Wildlife Service – Arctic National Wildlife Refuge for use of the G. William Holmes research station and for permitting our re- search; Polar Field Services, Inc./CH2M Hill for support and outfitting while in the field; Dirk Nickisch and Danielle Tirrell of Coyote Air for safely flying our field teams to and from Lake Peters; Lac-Core/CSDCO for assistance with processing and archiving of sedimentary sequences from Lake Peters; and PolarTREC for a productive partnership that contributed greatly to the broader impacts of this project.
