Chlorophyll-a concentrations estimated from particulate absorption coefficients and collocated particulate beam-attenuation coefficients between 620 and 710 nm.

The dataset was produced using measurements collected from the NASA SeaBASS database and during three Atlantic Meridional Transect cruises (https://www.amt-uk.org/) and it is described in more details in a paper currently under review [1]. The dataset consists of chlorophyll-a concentrations estimated from particulate absorption coefficients using the line-height method [2]. The dataset also contains the latitude, longitude, UTC timestamp and the name of the research expeditions during which each point was collected. Finally, the dataset contains collocated particulate beam-attenuation coefficients at 620 nm to 710 nm every 2 nm.
