attribute NC_GLOBAL history String Created with 03b_create_new_chl_files_gridded.R. Input data are 1km-resolution level-3 mapped remote sensing reflectances (Rrs) from the OC-CCI multisensor product (www.oceancolour.org) generated by the Plymouth Marine Laboratory (PML) as part of the European Space Agency (ESA) climate change initiative. Rrs are subset to the region of interest and used in conjunction with the most recent set of regionally-tuned parameters to create the level-3 mapped product.

attribute NC_GLOBAL summary String Chlorophyll-a concentration (Chl-a) is used as a proxy for phytoplankton biomass to track blooms and monitor the state of the ecosystem. This dataset is made of daily 1-km resolution images containing satellite Chl-a values computed using the OCxSPM-cor algorithm, covering the period from Sep 1997 to present day over the Bay of Fundy (43.1-46.2°N, 63.1-68.8°W). Regionally-tuned coefficients for OCxSPM-cor Chl-a (Wilson et al., 2024, see resources) were obtained by matching satellite pixels to in situ Turner fluorometry Chl-a samples within the region of interest. OCxSPM-cor Chl-a optimization used a linear regression of OCxSPM-cor against Turner that was forced to the 1:1 line to reduce the negative bias observed in higher concentrations in the default global Chl-a models. Daily Chl-a images were generated by applying the optimized OCxSPM-cor algorithm on level-3 binned remote sensing reflectance (Rrs) data from the OC-CCI multisensor product generated by the Plymouth Marine Laboratory (PML) as part of the European Space Agency (ESA) climate change initiative. The Chl-a data were then projected onto an Equidistant Cylindrical grid (1x1 km per pixel) using a nearest neighbour method. This model and the coefficients computed for the Northwest Atlantic and Bay of Fundy are available in the R package oceancolouR (https://github.com/BIO-RSG/oceancolouR).
