Isn't that water a bit ...blue?
It depends on one's position in relation to the Island. That's the actual color of the Gulf Stream. The surface color of the 'Stream stays pretty much the same, irregardless of one being off the East coast of Florida, East of North Carolina, SE of New Jersey, South of Nova Scotia, or South of Iceland.

"SeaWiFS. The Gulf Stream waters are warm and oligotrophic, low in nutrients. They are deep blue while the cooler, more-nutrient-rich waters to the north are milky blue due to the phytoplankton. (click on image for a larger version) Source: NASA Visible Earth."
And from this site:
http://old.fisheries.is/ships/grounds.htm"Looking at Iceland's northerly position on the map, one would expect the ocean around it to be icy cold and that very little production of phytoplankton could take place and become the basis for the food chain. One would expect the ocean to be rather lifeless. The fact is, however, quite the contrary because the ocean around Iceland is teeming with life. The explanation lies in the system of ocean currents around the country. As the warm Gulf stream approaching from the southwest meets the polar current from the north a huge amount of upwelling of nutrients takes place from the deeper layers to the surface. The nutrients feed microscopic life in the surface layers, notably phytoplankton and zooplankton and thus the ocean's entire food web.
The Gulf stream warms the ocean south off Iceland and flows north along the west coast and east along the north coast. It meets the polar current off the north and west coasts and also in the southeast."
Besides, if one does not like the water surface color in a Third Wire sim, it's not all that hard to "personalize" it to suit one's taste.
