Measuring chlorophyll concentration is the primary goal of most ocean colour (OC) studies.

Sentinel-3 OLCI is the workhorse for this task, as it is the best OC radiometer we have in space. However, OLCI has 300 m resolution. Though not designed for marine work, the S2 MSI radiometer has 10 m resolution. This work shows how ML can be used to seamlessly combine the two, delivering results that are much better than classical approaches. ML approaches like this are likely to become the mainstay of any coastal OC work. The technique is highly relevant to any researcher or agency that is investigating or monitoring the coastal or inland water domain.
