Soil accretion at 10 GCE marsh sampling sites from December 2011 to December 2016
The accretion of soil was measured in tidal marshes at 10 GCE-LTER sampling sites from December 2011 to May 2016 Feldspar marker layers were deposited in 0.25m by 0.25m quadrats in the marsh plain at each site in December 2011, then replicate soil cores were removed at approximately 6 month intervals to measure accretion above the marker layer. Due to bioturbation disturbing the sediments, Feldspar was re-deposited after cores were taken approximately every 6 months. This study is part of the GCE sediment monitoring program, and was conducted to evaluate the effects of freshwater input on soil accretion.
Fall 2019 grasshopper monitoring -- mid-marsh grasshopper abundance and species diversity at eight GCE LTER sampling sites
Grasshopper abundance and species diversity were investigated at eight sampling sites within the Georgia Coastal Ecosystems (GCE) LTER study area in August 2019. Visual surveys were conducted along 8 2m by 10m transects randomly allocated within the mid-marsh zone at each site. All grasshoppers observed within each transect were counted and identified to species, if possible. This survey was conducted as part of the GCE invertebrate monitoring program, and will be performed annually to assess long-term changes in relative species abundances across the GCE study area.
Fall 2000 plant monitoring survey -- biomass calculated from shoot height and flowering status of plants in permanent plots at GCE sampling sites 1-10
The biomass of plants surveyed in permanent plots at 10 GCE LTER sampling sites in October 2000 was estimated based on allometric relationships between biomass and shoot height and flowering status derived for each site, zone, and species in October 2002.

BSNE aeolian dust collector sample weights from the three ConMod Pilot study locations at Jornada Basin LTER, 2008-2016
This data package contains measurements of dust collected by BSNE collectors for the Connectivity Modifier (ConMod) Pilot study plots from 2008-2016 on the Jornada Experimental Range. There were 3 sites for this study: Gravelly Ridges, Aeolian, and Dona Ana. Within each site, there were 8 plots. The plots are 8 x 8 meters and have an 8 x 8 buffer zone on both sides of the plot (up and down). There are four BSNE (aeolian dust collector) stands for each plot, 2 in each of the 2 buffer zones (8 collectors per plot). Each stand contains 2 BSNE collectors at a 30cm height with the collection opening at 10cm x 2 cm wide x 5 cm height. These BSNE collectors are in a fixed position pointing into the direction of the prevailing wind, which corresponds to the plot alignment. The collectors in the upwind buffer are facing away from the plot and the collectors in the downwind buffer are facing into the plot. Upwind BSNEs collect the amount of dust entering the plot, and the downwind BSNEs collect the amount of dust moving off the plot. These collectors estimate the effectiveness of the plot surface in obstructing wind blown dust. This study is complete (finished in 2016) and was the pilot study to the newer Cross Scale Interactions Study.

CFC01 Kings Creek long-term fish and crayfish community sampling at Konza Prairie
Prairie stream fish communities have been monitored seasonally at multiple sites within the Kings Creek watershed since 1995. The objective of this sampling is to evaluate how these communities respond to seasonal and annual variation in environmental conditions. Specifically, we are interesting in testing the resistance and resilience of stream communities in response to flood and drought disturbances. One site in a downstream perennial reach of the watershed has been sampled since 1995. Five sites have been sampled in smaller tributaries in the watershed, two were discontinued due to often lack of flow, two have been sampled since 1995 and one was added in 2008. Sampling is conducted with backpack electrofishing with at least one person dip netting. At each site, multiple habitats (pools and riffles) are sampled. Length of all fish and crayfish are measured.

CSM08 Small mammal host-parasite sampling data for 16 linear trapping transects located in 8 LTER burn treatment watersheds at Konza Prairie
Data set contains summaries (summer) of the number of individuals of each species of small mammal captured (relative abundance) on each transect. Each record contains date, treatment, transect, trap station, species, specimen number, recapture status, specimen disposition, external body measurements (where applicable), reproductive information, and miscellaneous associated comments. These sampling records are based on nightly captures during one 4-night trapping period in summer (June through August) for each of 16 permanent transects established on eight fire treatments (two transects per treatment). These treatments include two seasonal burn watersheds (SpB, SuB), two reversal burn watersheds (R1A, R20A), one annual burn watershed (1D), two 4-year burn watersheds (4B, 4F, and one 20-year burn watershed (20B).
