From Belize to Barbados, tourist beaches have been swamped by huge tides of foul-smelling sargassum – and climate change could make the problem worse
Proliferation of thick brown algae is affecting fishing, tourism and marine life on both sides of the Atlantic, say scientists
Fuel shipments normally take place during autumn from departure ports such as Murmansk and Arkhangelsk. However, last fall saw a sudden freeze-up and quickly accumulating sea-ice on the Northern Sea Route, including the Kara Sea. Of the two rescued barges, one contained 7,000 tons of diesel fuel, while the other was loaded with 170 tons of kerosene.

High concentrations of harmful algae called Alexandrium catenella have been detected in the Bering Strait waters near St. Lawrence Island, Wales, and Little Diomede, posing a potential danger to human health and urging caution when consuming certain seafood.
Researchers stepping off the research vessel Norseman II in Nome last weekend, brought significant news of having found very high concentrations of a phytoplankton called Alexandrium catenella in regional waters. Alexandrium is an algae that can produce saxitoxins, which can cause dangerous paralytic shellfish poisoning in people. The scientists issued an advisory, notifying Norton Sound Health Corporation, UAF Sea Grant and the Alaska Division of Public Health.
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.
On Sunday night, a plump ringed seal pup was spotted on the ice in front of Breaker’s Bar on Nome’s Front Street. UAF Alaska Sea Grant agent Gay Sheffield was called and moved the pup to a more secluded beach. The ice had likely gone out too fast and the mother finished up the normal weaning process on the ice chunks in front of Nome.
Two more Russian LNG tankers made history earlier this month passing through the North Sea Route, which extends along the northern coast of Russian Asia, in late January, the latest commercial ship
St. Lawrence Island, home to two native villages in the region, is also the summer home of several migratory seabird species, including kittiwakes, auklets, murre and shearwaters. Over the last several years, though, the bird colonies on the island have been shrinking, and no one has been able to determine why.
A research vessel, Norseman II, was trapped in unusually dense sea ice for 14 days off the Seward Peninsula coast during a Pacific walrus study, but is now en route to Nome for repairs.
High winds that pushed water high up on south facing shores of the Seward Peninsula cause shoreline erosion on the Chukchi Sea coast of Shishmaref, last week.
The number of ships entering Canada's Northwest Passage, and the distances sailed, are all increasing, says a new report from the Arctic Council.
Graves at the historic St. Michael cemetery in Alaska are eroding due to increased storms and erosion, prompting an archaeologist to recover exposed remains and coordinate efforts to re-bury them. Tom Wolforth’s prime mission was to appropriately handle the remains and make sure they could be reburied. He has been working closely with the tribe and the municipality to address their concerns. One concern, Martin said, was that these exposed remains could pose a risk of disease, especially if the dead had been buried during the time of the 1918 flu pandemic. But Wolforth assured them that if properly handled this shouldn’t be a problem.
On Sunday, Nomeites noticed that their internet wasn’t working and that cell service was spottier than usual. Large fiberoptic line was damaged by sea ice deep underneath the moving sea ice above.
Looking seaward over the last week from almost all points along the coasts of Norton Sound, folks have been dazzled by bright blue horizons colored by open water.
Conception Bay South was dealt a hard hand by what some have dubbed the ‘storm of the century.’ At least two local churches, Topsail United and All Saints in Foxtrap saw siding ripped off their steeples by the 120 kph winds.The most extensive damage was along the coastline, with both CBS mayor Terry French and Royal Newfoundland Yacht Club Commodore Larry LeDrew estimating millions of dollars worth of damage.
After alerting the region to very high levels of harmful algal blooms west of Kotzebue and Gambell two weeks ago, scientist onboard the research vessel Norseman II have found even higher numbers of Alexandrium catenella algae cells near Wales, Diomede and Shishmaref.
