Bonanza Creek LTER: Hourly Soil Temperature Measurements at Various Depths from 1998 to Present in the Caribou-Poker Creeks Research Watershed near Fairbanks, Alaska

Hourly soil temperature is recorded at several sites within CPCRW. A variety of sensors are alo used including Campbell Scientific CS107's as well as a variety of thermistors.

Bonanza Creek LTER: Hourly Precipitation Measurements from 1988 to Present in the Bonanza Creek Experimental Forest near Fairbanks, Alaska

Precipitation is measured at many sites within BCEF using TE525 tipping buckets. These sensors are able to detect .254mm of precipitation and record hourly totals of rainfall or throughfall. It should be noted the tipping buckets within forested sites are subject to clogging by forest debris whcih can result in under reporting of rain events as well as over reporting upon release of the collected precipitation. There is data from floodplains to upland sites along a range of successional gradients.

Toklat River Fire in Denali National Park and Preserve: Site level environmental, soil, tree, vegetation, and fire characteristics measured in 2016

This dataset contains site-level average estimated of environmental, soil, tree, vegetation, and fire characteristics measured in 2016, three years after the Toklat River Fire in Denali National Park and Preserve. Measured parameters include latitude, longitude, slope, aspect, elevation, moisture classification, bulk density of the surface soil, residual organic soil depth, thaw depth, burn depth, density and basal area of all tree species pre-fire, the density of all tree species post-fire, estimates of above- and below-ground carbon combustion, and understory vegetation turnover from pre-fire to post-fire. There is also data on seed trap collection and experimental regeneration of seedlings collected in 2017 and 2018 at a subset of sites.

Continuous salinity, temperature and depth measurements from moored hydrographic data loggers deployed at GCE10_Hydro (Duplin River west of Sapelo Island, Georgia) from 01-Jan-2004 through 31-Dec-2004

Conductivity, temperature and pressure were measured continuously at Georgia Coastal Ecosystems LTER sampling location GCE10_Hydro (Duplin River west of Sapelo Island, Georgia) from 01-Jan-2004 through 31-Dec-2004. Observations were logged at 30 minute intervals by moored Sea-Bird Electronics MicroCAT 37-SM data loggers and downloaded approximately bimonthly. Salinity, depth and sigma-t were calculated from the measured parameters using standard UNESCO algorithms. This data set was collected as part of the GCE-LTER Project continuous salinity, temperature and water level monitoring program.

Sediment elevation measurements for 10 GCE-LTER sampling sites from December 2001 to December 2020

Soil surface elevation was measured in tidal marshes at 10 GCE-LTER sampling sites from December 2001 to December 2020 using a sediment elevation table method. The sites represent three estuaries of the Georgia coast (USA) that vary in delivery of freshwater and sediment. The study was conducted to evaluate the effects of freshwater input on marsh accretion and subsidence. In 2013, rod SETs were added at site 11 and installed to replace broken SETs at sites 7 and 9 (which broke in 2012).
