Excerpts;

A penguin colony in Antarctica has suffered a massive breeding failure, with only two chicks surviving the disaster.

Terre Adélie (Adélie Land) is home to more than 18,000 pairs of Adélie penguins, but this year almost all the seabirds’ babies starved to death.

The World Wildlife Fund said unseasonably extensive amounts of sea ice around the colony in East Antarctica had forced the adult penguins to travel further than normal to forage for food…

What happens to marine wildlife during hurricanes?

Excerpts;

Hurricanes are incredibly powerful storms that wreak havoc on marine and coastal ecosystems as they work their way from deeper water toward land. The force of the storm churns up water, mixing warmer water at the surface with cooler water from farther down the water column. In all this churning, what happens to the wildlife living in the storm-tossed waters?

Excerpts;

Marine authorities in the U.S. and Canada said Friday they will marshal resources to try to find out what’s behind a string of deaths of endangered North Atlantic right whales.

The animals are among the rarest marine mammals in the world, with only about 500 still living…

A variety of maritime activities contribute to sea turtle deaths

Excerpts;

Ask what water-based activity interacts the most with threatened and endangered sea turtles and many will reply without hesitation: commercial fishing.

But state records show that to be incorrect.

In the eight-week period beginning May 21, reports produced by the North Carolina Wildlife Resource Commission show a total of 101 incidental takes which are interactions with sea turtles. “Takes” mean any type of interaction and aren’t equated to mortality.

During that time frame, about five dozen are attributed to the beach nourishment projects in the northern municipalities…

Rob Young, who heads the Program for the Study of Developed Shorelines at Western Carolina University, said the government is subsidizing coastal development with renourishment money – and that’s costing taxpayers. Communities across the country have spent millions of dollars renourishing beaches. Those efforts encourage people to rebuild after every major hurricane…

Whales turn tail at ocean mining noise

Excerpts;

A new international study has measured the effect of loud sounds on migrating humpback whales as concern grows as oceans become noisier. Scientists have said one of the main sources of ocean noise was oil and gas exploration, due to geologists firing off loud acoustic air guns to probe the structure of the ocean floor in search of fossil fuels…

Accoustic Pollution and Marine Mammals, Nature
In the Canary Islands, 14 beaked whales washed ashore bleeding from the ears. All eventually died. A post-mortem examination revealed that the whales showed signs of decompression sickness (what scuba divers call “the bends”). Decompression sickness can occur when a mammal swims to the ocean’s surface too quickly, and the change in pressure produces lethal nitrogen gas bubbles that clog its blood vessels. Evidence of acute decompression sickness indicates unusual behavior. Over the past 40 years, cumulative research across the globe has revealed a coincidence between naval sonar testing events and acute decompression sickness in beached marine mammals…

90% of the goods we consume in the West are manufactured in far-off lands and brought to us by ship. The cargo shipping industry is a key player in world economy and forms the basis of our very model of modern civilisation; without it, it would be impossible to fulfil the ever-increasing demands of our societies. Yet the functioning and regulations of this business remain largely obscure to many, and its hidden costs affect us all. Due to their size, freight ships no longer fit in traditional city harbours; they have moved out of the public’s eye, behind barriers and check points…

Migratory seabird deaths linked to hurricanes

Excerpts;

Stronger and more frequent hurricanes may pose a new threat to the sooty tern, a species of migratory seabird found throughout the Caribbean and Mid-Atlantic, a new study reveals. The study is the first to map the birds’ annual migratory path and demonstrate how its timing and trajectory place them in the direct path of hurricanes moving into the Caribbean from the Atlantic. Climate change may increase the risk.

Although sooty terns are neither rare nor endangered — 80,000 or more of them are estimated to breed in the Dry Tortugas each year — they have long been used by scientists as an indicator species to determine the health of the region’s marine environment…
