New Calves Provide Hope

Each year from December through March, pregnant North Atlantic right whales head to warmer Southeastern waters to give birth. This time of year is known as calving season. Whales and their young can be seen gliding through the water, spurring optimism for this critically endangered marine mammal.

Tracking Right Whale Sightings Since 1935

Curated by the Aquarium, the North Atlantic Right Whale Catalog is a directory of more than a million photographs of right whales dating back to 1935. The catalog is considered an invaluable data source and relies on contributions of photographs from as many people and groups as possible. If you think you saw a right whale, submit your photo to the catalog. Every photo counts!

Researching the Ocean’s Biggest Residents

In addition to our right whale research, the Aquarium's dedicated research arm, the Anderson Cabot Center for Ocean Life studies a variety of other whale species to determine how humans and climate change are impacting their populations and habitats.
