Mixing and carbon processing in two natural ponds
收藏资源简介：
Ponds play an important role in global carbon (C) cycling due to high, but variable, C burial rates and emissions of carbon dioxide (CO2) and methane (CH4) to the atmosphere. Here, we sampled two ponds of similar size, but with contrasting stratification and dominant types of primary producers. We quantified organic C (OC) burial rates and CO2 and CH4 concentrations and fluxes. The dataset includes data on thermal mixing, water chemistry, carbon burial, CO2 and CH4 concentrations, and ebullitive CH4 fluxes. , See the associated manuscript in Limnology & Oceanography , , This readme.txt file was generated on 08-31-2024 by Meredith Holgerson GENERAL INFORMATION 1.
