Data from: Carbon burial in Cornell's experimental ponds

Ponds are globally abundant and important to the global carbon cycle.
While ponds have large greenhouse gas emissions, they may also sequester
large amounts of carbon in their sediments. Here, we studied carbon burial
rates in 22 experimental ponds without watersheds, where carbon
sequestration comes solely from autochthonous primary production. The
ponds were built identically in 1964 at Cornell University, and have since
experienced different management strategies. This dataset includes two
files: (1) spreadsheets related to carbon burial calculations (e.g.,
measuring sediment thickness, estimates of loss-on-ignition, and carbon
burial rates), and (2) spreadsheets of historical management practices for
our study ponds. These datasets accompany a manuscript accepted at
Limnology and Oceanography Letters.

池塘在全球分布广泛，对全球碳循环至关重要。尽管池塘会排放大量温室气体，但其沉积物中亦可固存大量碳。本研究针对22个无集水区的实验池塘开展碳埋藏速率研究，这些池塘的碳封存仅来源于原地初级生产。这批池塘于1964年在康奈尔大学（Cornell University）按统一标准建造，此后实施了各不相同的管理策略。本数据集包含两类文件：（1）与碳埋藏计算相关的电子表格（涵盖沉积物厚度测量、烧失量估算以及碳埋藏速率测算等内容）；（2）本研究涉及池塘的历史管理措施电子表格。本数据集配套一篇已被《湖沼学与海洋学通讯》（Limnology and Oceanography Letters）接收的研究论文。
