Nordic Seas intermediate water leaves through the Denmark Straight and the Iceland Ridge. The densest overflow waters leave through the Faroe Bank Channel. The water masses that encompass the Nordic Seas are always changing in response to the local variations that occur between atmosphere-ocean fluxes and convection of intermediate to deep water. The Nordic Seas are found between the North Atlantic and the Arctic Ocean, both having variable surface water conditions. The Nordic Seas are complex in the variety of water masses it contains: two surface waters, three intermediate waters, and three deep waters. Figure 3 shows the water mass circulations that
Milky seas effect Milky seas effect Milky seas, also called mareel, is a luminous phenomenon in the ocean in which large areas of seawater (up to ) appear to glow brightly enough at night to be seen by satellites orbiting Earth. Modern science only tentatively attributes this effect to bioluminescent bacteria or dinoflagellates, causing the sea to uniformly display an eerie blue glow at night. However, no modern research proves that bioluminescent bacteria are capable of illuminating the ocean from horizon to horizon and for days at a time, as described in mariners' tales for centuries (notably appearing in chapter 23 of Jules
