From 6/10. Mackenzie river coming in on left side of image. Note the bright green colors coming up in the water along the coast, and just big chunks of ice floating around (thin cirrus clouds interfere a bit with the view). This is actually a perfect environment for phytoplankton growth
Here's a satellite image of the Mackenzie River delta on June

That's the East Siberian Sea.
I think the darker color results mainly from the fact that the ice there is rapidly getting thinner, while sea currents are also contributing to the ice getting fractured into ever smaller pieces.
On the left is Chaunskaya Bay, where the East Siberian Sea is very shallow. The Bay is still covered with very thin ice. Underneath the ice warm water of the Chaun River is flowing into the Arctic Ocean.
On the right, warm water from the (ice-free) Kolyma River is flowing into the East Siberian Sea
