Abstract

This data set contains the raw data for measurements of carbon fluxes at four field sites along a successional gradient near Palmer Station, Antarctica. At the beginning of the experiment, field site 1 (youngest site, closest to the glacier) was approximately 2 years since deglaciation, field site 2 about 30 years since deglaciation, field site 3 about 60 years since deglaciation, and Litchfield Island: hundreds of years since deglaciation. These sites have each: 5 control plots and 5 warmed plots (warmed via open-top chambers, OTC). Carbon flux measurements were taken weekly at most sites (40 plots total). A custom chamber connected to a LI-COR 6800 was placed on a stainless steel ring. Then measurements were taken over a 90 second or 120 second interval. Measurements were taken with a transparent chamber to obtain net ecosystem exchange (NEE; micromols CO2/m2/s), and then covered with dark cloth to obtain ecosystem respiration (ER) measurements. The incoming carbon fluxes was then obtained based on the NEE and ER.
