Researchers Track Singing Humpback Whales on a Northwest Atlantic Feeding Ground

The Stellwagen Bank National Marine Sanctuary is an important feeding ground for Humpback whales who can be found there between April and December. By using passive acoustic monitoring techniques, researchers found that the humpbacks sing from April through May, following the spring migration from southern waters, and from August to December before they return south in the fall. Researchers also found that most of the singers were actively swimming. Although the humpbacks remain in the sanctuary throughout the summer, no singing has been recorded during that time when they are feeding.

Sea Turtles Benefiting From Protected Areas

A new study from the U.S. Geological Survey found that green sea turtles are benefiting from marine protected areas. The results show that nesting green turtles use habitats found within the MPA boundaries. This study is important because it shows policy-makers and managers that MPAs are effective and it helps researchers understand what kinds of habitats the turtles use the most.
