Hello ladies & gentlemen,
Does anyone know where I can source high resolution chlorophyll concentration data for the North Sea region from present day back to 2004 for free other than NASA Earth Observations (NEO)?
Any help would be greeted with the upmost appreciation.
Thank you,
Edward Lavallin
depends whether you search for larger scale spatially hires data or temporally hires data for specific locations (as to complement the NASA data).
Data are available from German Oceanographic data center:

e.g. data include data at Helgoland Reede on a 3-4 days resolution.
For other remote sensing data there is the VIIRS-sensor onboard Suomi NPP, see

Not sure, if/where/how to get the data set for the past years, but one can ask, I guess.
Give a lool to the Copernicus Marine Environmental Monitoring Service (CMEMS), formerly MyOcean.

There are various bio-physical parameters - including chlorophyll - obtained both from Earth Observation data and models which are provided at different resolutions. In some cases the data series start from earlier than 2000.

I think MODIS Chl-a is proper and free available. To gain more information, you can refer to the following publication:
