Two North Atlantic right whales ( Eubalaena glacialis ) swim at the surface of the water. Learn more about this species in the North Atlantic Right Whale section.
Through the use of satellites and land survey tools, scientists are learning about the effects of climate change on our ocean. By combining data regarding sea level and land elevation, they can see...
The ocean holds a lot of history. Warships from World War II have been found on the floor of the Atlantic Ocean through the use of sonar technology and are being explored before they give in to the...
This Marine National Monument protects a chain of atolls and reefs 1,931-kilometers (1,200-miles) long. The Hawaiian name for this chain is “Papahanaumokuakea,” which joins the Hawaiian words for...
