An annual time-series of Chlorophyll-a and Sea Surface Temperature measurements collected between 2017 and 2018 by a surfer at Bovisand Beach, Plymouth, UK.

This dataset consists of 67 Chlorophyll-a and Sea Surface Temperature (SST) measurements collected by a surfer at Bovisand Beach in Plymouth, UK, between September 2017 and September 2018. These data were collected as part of a research project supported by University of Exeter and Plymouth Marine Laboratory, and in collaboration with Scripps Institution of Oceanography, University of North Carolina Wilmington, and Nova Southeastern University. Chlorophyll-a concentrations were derived through collection of a water sample, subsequent filtration of the sample, extraction of pigment in solvent, and analysis using in-vitro fluorescence. SST data were primarily collected (65 measurements) using a Smartfin, though two samples were derived using a calibrated and protected UTBI-001 Tidbit V2 Temperature Data Logger attached to the leash of the surfboard. SST measurements represent the median temperature collected during the surfing session. Uncertainties in both SST and Chlorophyll-a are provided with the dataset.
