GCE-LTER Signature Data Sets
Signature data sets are the data streams that the GCE maintains to document long-term changes in external drivers and to assess the spatial and temporal variability of key ecosystem variables within the GCE domain. Some examples are:
External Drivers
Long-term sea level observations in the GCE domain
Weather station data from Sapelo Island
Freshwater discharge from the Altamaha River
Salinity, temperature, and pressure records at GCE hydrographic moorings
Ecosystem characteristics tracked at long-term sites
Soil accretion at GCE salt marsh sites
Salt marsh fluxes of heat, water and carbon
