A very nice image indeed

clear skies, no wind, lots of photons




An excellent calibration, particularly for the Soil Line, thanks to extensive very dark dry marshes.

Jerlov's water type OII+0.8: waters are not very clear in this isolated water mass with no major pass.

Some water masses are locally less clear: they cause some falsely darker bottom reflectances at places.
