When a whale dies at sea, its body often sinks to the seafloor. There, its carcass becomes what is known as a whale fall. The whale’s body provides a sudden, concentrated food source — a bonanza for organisms in the deep sea for years to come.
Our ocean is in constant flux. The National Marine Sanctuary System works to help sensitive habitats respond to human-made threats like climate change and pollution, and safeguards habitats you’ll find in surprising places. It’s all part of protecting Life in the Blue.
Each day, researchers in the National Marine Sanctuary System work diligently to uncover new information about our ocean and Great Lakes. They track enormous sharks and disentangle whales.
