A Russian village swallowed by sand

Excerpts;

Shoyna, a Russian fishing village on the frigid shores of the White Sea, is slowly vanishing under sand that engulfs entire houses, their roofs just barely visible above the dunes…

Overfishing not only depleted local stocks; it probably ruined the area’s ecosystem. Trawlers scraped the sea floor clean of silt and seaweed. And with nothing to hold the sand in place anymore, waves started washing it ashore, each of the trillions of grains a reminder of the reckless depredation of the seas.

This disruption of the seabed, perhaps combined with a natural change in the bed of the river that flows through Shoyna and into the White Sea, is the best suspect to blame for the sand invasion, said Sergey Uvarov, the marine biodiversity project coordinator for the World Wildlife Fund in Russia…

Marine Protected Areas overlook a large fraction of biodiversity hotspots

Excerpts;

Current marine protected areas (MPAs) leave almost three-quarters of ecologically and functionally important species unprotected, concludes a new performance assessment of the Finnish MPA network.

Published in Frontiers in Marine Science, the study finds the MPAs were designated with little knowledge of local marine biodiversity — and that increasing existing networks by just 1% in ecologically most relevant areas could double conservation of the most important species.

In addition to identifying areas of high conservation value, the methodology — which uses a unique new dataset of 140,000 samples — can also be used in ecosystem-based marine spatial planning and impact avoidance, including siting of wind energy infrastructure, aquaculture and other human activities…

Modern slavery promotes overfishing

Excerpts;

Labour abuses, including modern slavery, are ‘hidden subsidies’ that allow distant-water fishing fleets to remain profitable and promote overfishing, new research from the University of Western Australia and the Sea Around Us initiative at the University of British Columbia has found…

Dolphins are simplifying their calls to be heard over shipping noise

Excerpts;

The world’s oceans are getting noisier, humming with the near-constant sounds of ship engines, seafloor mining, and oil and gas exploration.

Now, a new study published in the journal Biology Letters has found that dolphins are being forced to simplify their calls in order to be heard over the noise…

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…

“FREIGHTENED – The Real Price of Shipping,” a movie by multi award-winning filmmaker Denis Delestrac-©-2016; (03-31-2016)
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…

Salty water causes some freshwater harmful algae to release toxins

Excerpts;

A new U.S. Geological Survey laboratory study of two potentially toxic types of freshwater cyanobacteria, or blue-green algae, found that exposure to salty water can damage the cyanobacteria cells’ walls, causing them to release their toxins into the water.

The finding suggests that understanding the mixing of fresh and salt water, which takes place in many coastal water bodies around the world, will help researchers understand the toxic effects of these harmful algal blooms…

Save Lighthouse Point, a true Bahamian treasure!

Excerpts;

Lighthouse Point is one of the last great remaining wilderness places in The Bahamas. Located at the southernmost tip of Eleuthera, it is home to incredibly diverse and unique terrestrial and marine ecosystems as well as cultural and historic resources.

Unfortunately, this outstanding Bahamian treasure is at risk of being lost to externally-driven, large-scale commercial development…
