A NASA-sponsored expedition is set to sail to the North Atlantic’s saltiest spot to get a detailed, 3-D picture of how salt content fluctuates in the ocean’s upper layers and how these variations are related to shifts in rainfall patterns around the planet.

The research voyage is part of a multi-year mission, dubbed the Salinity Processes in the Upper Ocean Regional Study (SPURS), which will deploy multiple instruments in different regions of the ocean. The new data also will help calibrate the salinity measurements NASA’s Aquarius instrument has been collecting from space since August 2011. (more…)

Prey-tell: Why Right Whales Linger in the Gulf of Maine

As they might with most endangered animals, scientists consider the whereabouts and activities of right whales extremely important. “It is helpful to know where they go, why they go there and what they do when they’re there,” says Mark F. Baumgartner of the biology department at the Woods Hole Oceanographic Institution (WHOI).

Baumgartner and his colleagues studied the behavior of right whales and sei whales—both endangered species of baleen whales—in the waters of the Gulf of Maine to the east of Nantucket. They found that the location, the length of stay, and perhaps the very abundance of the whales may be dependent on an interesting vertical migration pattern by the copepods on which the whales feed. It seems to be a case, he said, of “how the behavior of the prey influences the behavior of the whales.” (more…)
