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).

B.C.'s wild bighorn sheep are facing a deadly threat from a pneumonia-causing bacterial disease

A bighorn sheep herd in B.C.’s interior is in trouble after coming into contact with domestic sheep and the contagious disease they carry.

Appears to be smothering all aquatic plant life.

Update: Aug. 16. Mainstream Canada has announced that the Millar Channel fish farm is now empty. The fish, infected with the IHN virus,were taken to a rendering facility. Mainstream Canada is developing a plan for cleaning and disinfecting the farm site, as per the requirements of the Canadian Food Inspection Agency. “This is an unfortunate incident, but we are pleased with how smoothly the depopulation procedure went considering the situation,” said Fernando Villarroel, Mainstream Canada’s managing director.

The Shuswap Nation Tribal Council is very concerned about the conclusive finding of the European Strain of Infectious Salmon Anemia virus (ISA) in sockeye in Rivers Inlet. The Secwepemc, like "most BC First Nations, have relied on salmon as the life blood of our people. Between 50 and 90 per cent of our people's diet consisted of salmon at the time of contact.

Cyanobacteria blooms usually occur in summer.

Some residents in B.C.'s Central Interior are being told to avoid drinking or bathing in their tap water following an outbreak of potentially toxic algae blooms.

Halobacteria thrive in bodies of water with high levels of salt. The salinity inside the Kealia Pond outlet area is currently greater than 70 parts per thousand, twice the salinity of seawater. Maui's drought is likely contributing to the situation. Normally Waikapu Stream feeds into Kealia Pond and raises water levels there, but Wolfe said that hasn't happened in a long time.

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.

The river, which starts at the Saskatchewan Glacier in the Columbia Icefields and flows through to central Saskatchewan, is usually murky brown by the time it reaches Edmonton in summer. In recent weeks, however, the water has taken on the hues of Alberta's glacial lakes, thanks to dry, hot weather combined with maintenance at a major dam.
