Boaters in Skolebukta outside Larvik opened their eyes when they were visited by the famous beluga whale. The marine biologist fears the whale's journey could soon be over for good.

"My son found this helmet floating here in Prince William Sound."

A NOAA Ocean Exploration-led team has discovered what appears to be evidence of a large gas seep at a depth of nearly 1.4 miles (2,300 meters) along the Aleutian Trench. The discovery was found in data collected during the Seascape Alaska 1: Aleutians Deepwater Mapping expedition.

However, numerous fishermen say the assessment of a decline in the stock doesn't match what they're seeing on the water, where haddock appear to them to be plentiful.

When the fisherman Lars-Ivar Dale pulled up his net, he suddenly saw a species of fish he had never seen before. Fish scientist is now asking for help.

Researchers at UiT The Arctic University of Norway have found a new volcano at Bjørnøya in the Barents Sea. "Seeing an underwater mud eruption in real time reminds me how 'alive' our planet is," says the expedition leader.

Experts say Thursday's flight wasn't supposed to have gone off without a hitch, and still offers SpaceX valuable data. A space industry analyst explains why it was so significant.

"In our country Afghanistan I have observed that the level of water is decreasing day by day."

It’s only the second time in history that the ocean salmon fishery has been closed in California, and the decision reflects a major decline in fish populations after the state’s driest three-year period on record.

Testing has revealed black algae washing on Waiheke shores is toxic. “Currently the algal bloom on some Waiheke beaches could lead to skin or eye irritation if you are in contact with the water,” said Dr David Sinclair, Te Whatu Ora’s Northern Region medical officer of health.

There are miles of dead fish washing up on the beach. That's not all. Just breathing the air can be harmful.

A red tide bloom was found in multiple areas of coastal Collier County. Individuals with chronic respiratory problems should be cautious and stay away from this location, as red tide can affect breathing. Residents near the beaches are encouraged to close windows and run the air conditioners.

ABL Space Systems is still investigating the crash, but says the rocket rose more than 700 feet before its engines shut down 11 seconds after launch.

Test results show the bloom was almost certainly to blame for mass deaths of kina as well as crayfish, starfish and sea cucumber which washed ashore at Hardinge Rd, including Sandy Beach, and on a small part of Westshore Beach eight days ago.

A Wales resident shot and killed the bear. With the loss of sea ice and the ocean staying open later in the year, polar bears have been spending more time on land, which increases the chance of human encounters.

For the first time ever recorded, orca washes ashore in Florida.

A rare sighting is possible indicator of prey abundance.

The lack of winter sea ice is keeping temperatures warm. Climatologist Rick Thoman says it's a "very clear climate change signal."

December should have sea ice development in Norton Sound. But no sign of ice yet this year. Several storms have moved northward across the western Bering Sea and brought strong winds and bouts of above freezing weather to the Teller area and all of the Bering Strait region.

The Bering Sea’s cold pool, a critical part of the seafloor ecosystem, had shrunk to a worrying degree in recent years, but it is continuing to slowly return, according to the latest results of NOAA’s bottom trawl survey. Saffron cod, also called tomcod, seems to be bouncing back after a few bad years, and Arctic cod and blue king crab numbers were also better.
