West Coast Harmful Algal Bloom
Over the past few months, a massive toxic bloom of the marine diatom *Pseudo-nitzschia*, stretching from central California to the Alaska Peninsula, has resulted in significant impacts to coastal resources and marine life. NOAA has been working closely with federal, state, tribal, academic, and other partners to respond to this unprecedented harmful algal bloom (HAB).

Best sockeye return in 100 years
Fisheries Minister Gail Shea is crowing about the opportunities with the 2010 return of sockeye to the Fraser river, calling it a  banner year for Fraser River sockeye salmon. This year's return is currently set at just over 25 million fish, one of the highest returns in the last hundred years. Several fishery openings for Fraser River sockeye have already occurred in 2010 and more are planned, she said.

With no dam to stop it, the Eklutna River is temporarily reborn. Many people hope to keep it alive for good.
Conservation and tribal groups in 2018 removed a downstream dam in the river northeast of Anchorage. But an upriver dam provides the cheapest energy in Southcentral Alaska. For people from the Native Village of Eklutna the river’s rebirth was an important moment. They want the 12-mile-long waterway permanently restored, along with the salmon their late elders once described as abundant.

Corals in peril at a popular Hawaiian tourist destination due to global climate change
Researchers from the Coral Reef Ecology Lab at the Hawai'i Institute of Marine Biology documented the third global bleaching event as it occurred from 2014 to 2016 at the Hanauma Bay Nature Preserve (HBNP) on the island of O'ahu, Hawai'i. Their findings, published in the international journal PeerJ, show that temperature is by far the most influential factor in coral bleaching at this well-managed location where corals, fish, and all other organisms are protected.
