Abstract
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).
Highlights
Arctic glacier-fed lakes are complex and dynamic systems that are influenced by diverse physical processes
We present the results of a 4-year instrumentation campaign in the watershed of Lake Peters, a large glacierfed lake located in the northeastern Brooks Range within Alaska’s Arctic National Wildlife Refuge
The meteorological, glaciological, fluvial, and lacustrine datasets from Lake Peters and its catchment presented in this paper offer a unique and valuable opportunity to study an Arctic glacier-fed lake system
Summary
Arctic glacier-fed lakes are complex and dynamic systems that are influenced by diverse physical processes. Long-term instrumental datasets that document how weather and climate impact glaciers, basin hydrology, and sediment transport through rivers and lakes are rare, especially in the Arctic. Such datasets are critical for studying how Arctic glacier– river–lake catchments operate as a system, for understanding the processes that control sediment accumulation in lakes, and for contextualizing modern climatic and environmental change relative to past centuries. We present the results of a 4-year instrumentation campaign in the watershed of Lake Peters, a large glacierfed lake located in the northeastern Brooks Range within Alaska’s Arctic National Wildlife Refuge.
