No, this is Odyssey II, an autonomous sub developed at MIT's Sea Grant lab. Three of these robotic fish will swim through the Labrador Sea next winter for some cold-weather oceanography.
Arrows show the cold plumes that interest oceanographers.
Going down In the frosty Labrador Sea, up near Greenland, there's a curious region that climate experts would love to study. Like atmospheric winds, ocean currents are part of a global climate machine that distributes heat around the planet. Since oceanic heat transfer is a key component of computer climate models, currents and plumes are intensely important to anybody who worries about global climate change. But studying the plumes is a nasty job, since they form in bitter February cold, when the wind is frothing a sea of whitecaps. But until scientists can observe and measure them, the picture of how Earth's climate works will remain incomplete.
