Whales
Whales are among the largest and oldest animals on Earth. They can be found in every ocean and range in size from the smalldwarf sperm whale to the massiveblue whale, the largest animal on the planet. Whales belong to a group of marine mammals called cetaceans.Marine mammals in the cetacean family include whales,dolphins, and porpoises.
There are two types of cetaceans: baleen and toothed. Baleen whales, or Mysticetes,have baleen plates which sieve prey, like krill, from the water.Toothed whales, or Odontocetes, have teeth and feed on fish, squid, and other marine mammals such as seals and sea lions.
Together with our partners, we work to ensure the conservation of whales which are all protected under theMarine Mammal Protection Act, and protect and recover those that are listed under theEndangered Species Act.

A gray whale and her calf migrate north along the California coast on their way to summer feeding grounds in the Arctic. Scientists are using an unmanned aerial vehicle to produce very precise overhead images of gray whales, then analyzing the images to understand how environmental conditions affect the health of adult females and ultimately the reproductive success of the population.

Research
Monitoring the Ecosystem in the Northeast
The most comprehensive, ongoing program exploring marine resources and oceanographic conditions in the Northwest Atlantic. Our analyses inform local and international fisheries management, protected species research, and climate science.
Surveys in the Northeast and Mid-Atlantic
We conduct research and monitoring surveys to better understand the physical, biological, economic, and social components of marine ecosystems found in the Northwest Atlantic Ocean from the Canadian Scotian Shelf to Cape Hatteras, North Carolina.
