Are changes in surface water chlorophyll fluorescence related to metabolism metrics across lake types and seasons? #ChlF>=<Met

High frequency dissolved oxygen (DO) are now commonly used to examine whole-lake metabolism.  This project is using high frequency data from a set of lakes to calculate metabolism estimates (GPP, NEP and R) for the same time period for which chlorophyll (Chl) fluorescence data are available.  The project is exploring periods of coupling and decoupling between proxies for phytoplankton growth rates and metabolism metrics at a daily time step across lake types . Additional questions which will be addressed include relationships to local weather and thermal structure, and relationships to species composition (where these data are available). The project is using an archive of data on Chl fluorescence, DO, temperature profiles, and associated meteorological variables from 18 lakes which has been collated by signal processing working group.
