Circumpolar Flaw Lead (CFL) Photosynthesis-Irradiance Experiments
The objective of the Circumpolar Flaw Lead (CFL) project is to examine how physical changes affect biological processes within the flaw lead. The CFL system is formed when the central pack ice (which is mobile) moves away from coastal fast ice, opening a flaw lead. The CFL forms in the fall and continues as thin ice or open water throughout the winter. The flaw lead is circumpolar, with recurrent and interconnected polynyas occurring throughout the Arctic. The overarching objectives of the CFL project were to contrast the physical and biological systems of the flaw lead open water and thin ice to the adjacent landfast ice cover. The system will be studied throughout its yearly cycle, to determine the effects of global warming.
This data set contains results of photosynthesis-irradiance experiments. This dataset has the data formatted as an Excel document and as a CSV document (delimited by tabs and double quotes).
