Interested on whether oceanic DMS concentration can be detected by satellite image. Only found a couple of inconclusive references from 1990s. While I have your attention, is DMS and Chla correlated? Many thanks!
The relationship between DMS and chlorophyll-a is complex. There are some relationships between both that can be used to derive fields of DMS from RS. But these relationships usually collapse when applied in areas where the phyto community is very different (from the original analysis) or in highly productive areas. Check out paper below
Hope this helps

To date the only climatologies that I'm aware of come from dynamic simulations, or through statistical models.
There are a lot of studies that have tried to link chla to dms, but there are also relationships with mixed layer depth, as well as species composition of phytoplankton. And all those relationships differ by region as well.
So in short, no, DMS cannot be measured from satellite (but who knows where technology may go!)
Thanks for your reply. Nice book. I could not find any reference to DMS but I assume you are saying in your book that only Chla can be reliably detected by satellite:
"Chlorophyll is the only biological component of the marine ecosystem accessible to
remote sensing (via ocean colour).."
