Specific conductance and temperature data from I8 Outlet near Toolik Field Station, Alaska, summer 2012
As a part of the CSASN project, background (or ambient) specific conductance and stream water temperature was continuously monitored in three streams within the Toolik Inlet watershed from 2010 - 2012 summer/fall seasons. HOBO U24 data loggers were used for data acquisition. The data included in this file is from I8 Outlet stream, 2012 season.
discharge data from Peat Inlet near Toolik Field Station, Alaska, summer 2010
As a part of the CSASN project, daily average discharge was estimated in three streams within the Toolik Inlet. HOBO U20 data loggers were used for stage (water depth) data acquisition, and a rating curve relationship between stage and occasional dilution gauged discharge measurements was established to transform continuous stage measurements to continuous discharge measurements. The data included in this file is from Peat Inlet stream, 2010 season.

As a part of the CSASN project, daily average discharge was estimated in three streams within the Toolik Inlet watershed from 2011 - 2012 summer/fall seasons. HOBO U20 data loggers were used for stage (water depth) data acquisition, and a rating curve relationship between stage and occasional dilution gauged discharge measurements was established to transform continuous stage measurements to continuous discharge measurements. The data included in this file is from Peat Inlet stream, 2011 season.

Permafrost soil database with information on site, topography, geomorphology, hydrology, soil stratigraphy, soil carbon, ground ice isotopes, and vegetation at thermokarst features near Toolik and Noatak River, 2009-2013
This database contains soil and permafrost stratigraphy associated with thermokarst features near Toolik Lake and the Noatak River collected by Torre Jorgenson and Andrew Balser during summers 2009-2011. The Access Database has main data tables (tbl_) for site (environmental), soil stratigraphy, soil physical data, soil chemical data, soil isotopes (ground ice), soil radiocarbon dates, topography and bathymetry, and vegetation cover. The site data includes information of location, observers, geomorphology, topography, hydrology, soil summary characteristics, pH and EC, soil classification, and vegetation cover by species. Soil stratigrapy has information on soil texture and ground ice. Soil physical and chemical data includes lab data on bulk density, moisture, carbon, and nitrogen. The database has 37 reference tables (REF_) that have codes and descriptions for variables used in site, soil stratigraphy, and vegetation cover tables.
Surface soil characteristics for six thermokarst chronosequences near Toolik Field Station and Noatak National Preserve, Alaska
Surface organic and mineral soil layers were sampled in retrogressive thaw slump disturbance scars and nearby undisturbed tundra to estmate the influence of this thermo-erosional--thermokarst--disturbance type on soil carbon (C) and nitrogen (N) pools. Within six independent sites, we identified multiple thaw slump scars and determined time after disturbance for each scar by (1) aging the population of tall deciduous shrubs rooted in the mineral soil and (2) by dating the basal layer of the re-accumulating soil organic matter. Within each scar or paired undisturbed tundra site, we sampled replicate soil profiles volumetrically and analyzed samples for horizon depth, coarse, fine and rock fractional contribution, pH, bulk density, moisture content, and C and N concentration.
Weekly biomass and abundance of sweepnet-captured aboveground arthropods at four sites near Toolik Field Station, Alaska, summers 2010-2014
The abundance and dry biomass of canopy-dwelling arthropods (insects and small spiders) was tracked over five summers (2010-2014) at four sites near Toolik Field Station, Alaska. At each site, a shrub-dominant and tussock-tundra habitat was chosen for sampling, for a total of 8 sampling locations. At each sampling location, a 100-meter transect was established. Arthropods were sampled along the transect weekly by passing a sweepnet through and over the vegetation. After killing the arthropods with pest strips and freezing, they were sorted from the associated leaf litter and counted. Dry biomass of the arthorpods was estimated in one of two was: using family-level identification, digital microscope measurement, and published allometric length-mass equations; or, arthropds were weighed directly on a microbalance following 48 hours in a drying oven at 50°C.
Dissolved organic carbon (DOC) measurements from Toolik Lake Inlet and Toolik Lake main, Toolik Field Sation, North Slope Alaska for 2005-2008.
Dissolved organic carbon (DOC) measurements from Toolik Lake Inlet and Toolik Lake main sampling station for 2005-2008. The earliest measurements were in May and with the latest in September.
Plant biomass in moist acidic tussock tundra experimental small mammal exclosures, 1999 Arctic LTER Toolik, Alaska.
Above ground plant and below ground stem biomass was measured in Arctic LTER tussock tundra experimental small mammal exclosures. Treatments included Control, Nitrogen plus Phosphorus with both fenced and unfenced plots. In addition a moist non-acidic tussock tundra site was harvested. Leaf areas were also measured for each quadrat but are in a separate file.
