| Gaius Shaver, 2005 Daily summary of 10 cm soil temperatures in the Arctic LTER moist acidic experimental plots from 1998 to present, Toolik Lake Field Station, Alaska.. 10.6073/pasta/89b6208bc6631129949eeca791063ed3 |
Daily summary of 10 cm soil temperatures in the Arctic LTER moist acidic experimental plots for the control (CT), greenhouse (GH), greenhouse plus nitrogen and phosphorus (GHNP) and nitrogen and phosphorus (NP) plots. Soil temperature probes in the tundra soil were problematic with frost heaving causing the depth of measurements to change. In order to provide a consistent year to year temperature record notes on changes in depths were used to select the temperature sensor that was within + or – 3 cm of the 10 cm and then averaged daily. |
| Gaius Shaver, 2019 Soil and canopy temperature data from the Arctic LTER Moist Acidic Tussock Experimental plots (MAT89) from 2012 to 2018, Toolik Field Station, North Slope, Alaska. 10.6073/pasta/5394ebed0c558da5882a456d7f4da9f3 |
Soil and canopy temperature data from the Arctic LTER 1989 Moist Acidic Tussock Experimental plots(MAT89). The station was established in 1990 in block 2 of a 4 block random block design. The plots are located on a hillside near Toolik Lake, Alaska (68 38' N, 149 36'W). Treatments include - control (CT), greenhouse (GH), greenhouse plus nitrogen and phosphorus (GHNP) shade (SH), shade plus nitrogen and phosphorus (SHNP) and nitrogen and phosphorus (NP). Profiles include above and within canopy, 10, 20 and 40 centimeter soil depths. Not all treatments have a complete profile. |

We measured the flux of bulk material and major macronutrients (carbon, nitrogen and phosphorus) from the water column to the benthos in four separate lakes during the summer of 2009. The lakes were chosen to investigate the impacts of disturbance on lake sedimentation. Two of the lakes, Dimple and Perched, were within catchments that were burned by the 2007 Anaktuvuk River wildfire. Two of the lakes, NE-14 and Perched, were receiving elevated sediment loads from thermokarst failures on their shorelines, and Toolik Lake was used as a reference lake. |

| Gaius Shaver, 2022 Late season thaw depth measured in the Arctic Long Term Ecological Research (ARC LTER) moist acidic tussock experimental plots at Toolik Field station, Alaska Arctic 1993 to 2021. 10.6073/pasta/e24f9ed96718c7a6d020c1be6ae5853f |
Late season thaw depth was measured in the Arctic Long Term Ecological Research (ARC LTER) experimental plots (1981 Moist Acidic Tussock, 1989 Moist Acidic Tussock, 2006 Low Fertilization Moist Acidic Tussock, 1989 Moist Non-acidic Tussock, 1989 Moist Non-acidic Non-tussock and 1989 Wet Sedge tundra) at Toolik Lake, Alaska using a steel thaw probe. Note: for 2017-2018 only 1989 Moist Non-Acidic Tussock Tundra and 2006 Low fertilization Moist Acidic Tussock Tundra were measured. For other sites it has become difficult to distinguish rocks from frozen soil with a steel thaw probe. |
