Tsunamis, giant waves caused by underwater earthquakes, speed across the ocean at 400 miles per hour. Early warning systems, such as NOAA’s DART systems, are key to saving lives. Today, 47 DART...
What reef animal comes in a rainbow of crazy colors, can throw out its stomach to immobilize predators, then creep away and regrow a brand-new stomach? It’s the sea cucumber, prized as a gastronomic...
Ocean conditions change every hour of every day. Tides, currents, and winds are constantly in flux. NOAA’s real-time data helps huge ships navigate safely under bridges and around obstacles. Explore...
A dive tender monitors the line connected to ice divers studying creatures living on the underside of the Arctic Sea ice .
Both humans and sea lions get sick from eating fish and shellfish that have been feeding on harmful toxic algae. Studying the sick sea lions brings scientists closer to understanding and preventing...
The Kemp’s ridley is a “riddler” among sea turtles . Although the species was initially recognized in 1880, scientists didn't know where it nested until 80 years later, when a film documenting about...
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...
Two events made me passionate about deep-sea corals . One was my first submarine dive in a deep-sea coral bed off the Hawaiian island of Oahu. There was an incredibly lush community of corals and...
This whale is entangled in fishing gear. Entangled whales often need human help to break free from the fishing gear . But the job is hard one that requires handling a small boat near the large (and...
Nine years ago I was invited by a colleague to join a research team investigating deep-sea coral habitats . I was asked to examine the invertebrates associated with these ecosystems. After my first...
