Lake basin water level and ground temperature data in Arctic Alaska, 2019-2020
Lakes are abundant features on coastal plains of the Arctic and most are termed "thermokarst" because they form in ice-rich permafrost and gradually expand over time. The dynamic nature of thermokarst lakes also makes them prone to catastrophic drainage and abrupt conversion to wetlands, c...

Lakes are abundant features on coastal plains of the Arctic and most are termed "thermokarst" because they form in ice-rich permafrost and gradually expand over time. The dynamic nature of thermokarst lakes also makes them prone to catastrophic drainage and abrupt conversion to wetlands, called drained thermokarst lake basins (DTLBs). Together, thermokarst lakes and DTLBs cover up to 80% of arctic lowland regions, making understanding their response to ongoing climate change essential for coastal plain environmental assessment. Datasets presented here document water level and temperature (surface and ground) regimes for a large (23 sites in 2019-2020) array of lake with high drainage potential and lake basin (DTLBS), which have already drained, located on differing terrain units of Alaska's Arctic Coastal Plain. Lake data was measured along deep protected shorelines using pressure transducers to record hourly water level and bed temperature. Wetland (DTLB) data was also measured with pressure transducers and ground thermistors at 25 and 100 centimeters (cm) depth. Of special interest at some DTLB sites was the potential occurrence of snow-dam outburst events during the early summer snowmelt periods. In these cases, pressure transducers were set to log at 10 minute intervals for this period. All data archived here are summarized at daily average values. |
