Vincent Saba, a fisheries researcher with the National Oceanic and Atmospheric Administration’s Northeast Fisheries Science Center, said he’s worked on related studies showing that weakening of the Gulf Stream system leads to regional warming of the waters along the continental shelf of Northeastern North America, prime grounds for commercial and recreational fishing.
The Ocean Cleanup, which has raised $35 million in donations to fund the project, including from Salesforce.com chief executive Marc Benioff and PayPal co-founder Peter Thiel, will deploy 60 free-floating barriers in the Pacific Ocean by 2020.
Between 1982 and 2016, the number of “marine heat waves” roughly doubled, and likely will become more common and intense as the planet warms, a study released Wednesday found. Prolonged periods of extreme heat in the oceans can damage kelp forests and coral reefs, and harm fish and other marine life.
more than 120 others from conservation, business, science, social justice, youth and student groups, along with public officials from both parties (and independents) will be attending March for the Ocean. This will take place Saturday June 9, World Oceans Day weekend, in Washington DC and other locations around the world. It will be the first ever mobilization on behalf of a healthy ocean and clean water for all. Half a century ago we marched to save the whales. Now we’re marching to save it all.
Human actions have already increased carbon on the planet by about 40 percent. A quarter of that goes into the ocean. And the ocean has decreased by about .2 pH units, which may not sound like a lot. But, pH is a logarithmic scale like the Richter scale. So .2 pH is about 30% more acidic than it was before the Industrial Revolution.
A slogan of the last century was ‘think globally, act locally.’ But if we’re to deal with the collapse of living systems today we have to think and act locally, regionally and globally simultaneously. That would probably not be possible without the communications tools we now have on our laptops and other devices.
Editor’s Note: The Chumash Heritage National Marine Sanctuary Nomination has been proposed to NOAA. The proposed marine sanctuary would begin at Santa Rosa Creek in Cambria at the Monterey Bay National Marine Sanctuary southern boundary, and end at Gaviota Creek in… Read More ›
Water is much denser than air, so its molecules are packed tighter together. This means that sound (which relies on molecules vibrating and pushing against one another) propagates muchfurther and faster under water than in air.
