This offshore cage is stocked with 70,000 Pacific threadfin ( Polydactylus sexfilis ), or moi. Aquaculture can provide a sustainable way to satisfy the demand for this Hawaiian delicacy, once...
Marine biologist Mette Kaufman measures the temperature of a recently-drilled ice core . Variations in temperature at different points of the ice core provide information about the living conditions...
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...
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 Arctic is one of the most remote and uncharted areas of the world. With all the amazing discoveries hidden in the ice and water, Arctic exploration is truly a new scientific frontier.
The National Ice Center’s work is focused on ensuring safe and efficient navigation, but it also supports scientific research and provides crucial information used by scientists to better monitor and...
It takes special equipment and many warm layers of clothing to dive safely beneath Arctic sea ice . Ice divers look for holes in a melt pond in order to enter the frigid waters.

Did you know that 80 percent of the volcanic eruptions on Earth take place underwater? These underwater eruptions occur regularly, forming new landmasses and providing a living environment for deep-...
When most people think of iconic American landscapes, we think of places on land. Yellowstone, the Great Smoky Mountains, the Grand Canyon—these national parks are household names. But many Americans...
Forensics is a key tool for enforcing the laws and treaties that protect marine animals. Investigators in a recent case used DNA analysis to track down and convict sea turtle poachers. All seven...
Dr. Clyde Roper (top left), of the Smithsonian Institution, and scientists from NOAA and the Delaware Museum of Natural History dissect a giant squid specimen donated by NOAA. Everything we know...
Ocean debris is a global problem that is slowly destroying the biological aspect of our waters. With the help of our communities we can start making the right decisions to keep our oceans clean and...
How many animals swim in the sea? It's not easy to count them all. To get a feel for the ocean's diversity, scientists, such as those involved in the Census of Marine Life , sail out on research...
Instead of adding castaway fishing nets to already crowded landfills, Hawaii’s multi-partner marine debris group has developed a method of converting marine debris into usable electricity. The Nets-...
Bycatch, the name given to fish and other ocean animals that are caught unintentionally, is a huge problem. Scientists and fishermen are joining forces to design new nets that catch only the targeted...
Ice divers Katrin Iken (left) and Elizabeth Siddon are about to descend through a hole in the Arctic ice and into the frigid world below.
Several species of deep-sea corals form a garden 165 m (540 ft) below the ocean’s surface off the coast of Alaska’s Aleutian Islands. Explore more in the multimedia feature " Coral Gardens of the...
