Ocean biologists are starting to learn about the world’s largest fish, and the information should help efforts to protect endangered whale sharks.
Giant whale sharks, up to 60 feet long, feed mostly on tiny drifting animals and small fish like sardines. To find enough food, they endlessly cruise vast reaches of ocean to find dense swarms of prey. The learn more, scientists have been tracking the whale sharks in the eastern tropical Pacific, finding that they spend most of their time along ocean fronts, which are dynamic boundaries of cold and warm water masses that stimulate life.

Environmental attorneys are going to be busy the next few years under an onslaught of proposed fossil fuel development projects, including offshore oil and gas drilling.
As part of the Trump administration’s misguided push for “energy dominance,’ the federal government is preparing to create a new new nationwide offshore leasing plan that could open all U.S. waters to dangerous drilling. Last week, the administration said it will ask the fossil fuel industry where it wants to drill. Continue reading “Is offshore drilling coming to a beach near you?”→
Major study shows need for expansion of protected areas
As much as a third of the world’s oceans should be protected to help buffer against long-term climate change impacts, scientists said in a new study, calling for an expansion of protected areas, as well as better management.
Globally, coastal nations have committed to protecting 10 percent of their waters by 2020, but only 3.5 percent of the ocean has been set aside, and less than half of that (1.6 percent) is strongly protected from exploitation.
Results of the study, which evaluated 145 peer-reviewed studies on the impact of marine reserves, is being published this week in Proceedings of the National Academy of Sciences.
“Marine reserves cannot halt or completely offset the growing impacts of climate change,” said Oregon State University’s Jane Lubchenco, former National Oceanic and Atmospheric Administration (NOAA) Administrator and co-author on the study. “But they can make marine ecosystems more resilient to changes and, in some cases, help slow down the rate of climate change.

Defying local communities, Trump seeks to open area for oil drilling
In the bizarro alt-reality universe of Trumpistan, there’s nothing like celebrating the world’s oceans by opening them up for oil drilling — and that’s just what the oil-stained kleptocrat wants to do by authorizing five companies to search for oil off the Atlantic Coast — from Florida to Delaware — using loud seismic airgun blasts that hurt whales, dolphins and other animals. The exploration activities are the first step to opening the Atlantic to new oil drilling.
The move comes even as communities up and down the Atlantic Seaboard have said loud and clear they are not interested. Nearly 100 municipalities from New Jersey to Florida have adopted resolutions rejecting seismic blasting off the East Coast. And more than 40,000 local businesses and business associations have publicly opposed it, citing threats to marine life and local economies.

Pollution from Chinese factories is changing the nutrient balance in the ocean, say scientists who studied depositions of chemicals and plankton blooms in the East China Sea. These waters are increasingly threatened by harmful algal blooms that choke off vital fish populations, according to the new study, led by researchers at the University of California, Irvine.
“There has been massive growth in emissions from China’s factories and cars over the past few decades, and what comes out of the smokestacks and tailpipes tends to be richer in nitrogen than phosphorus,” said Katherine Mackey, assistant professor of Earth system science at UCI and lead author of the study, published recently in Frontiers in Marine Science.

With perhaps fewer than 100 vaquitas remaining in the Gulf of California, conservation experts say they will start a last-ditch recovery effort by trying to capture several of the marine mammals and keeping them in a temporary sanctuary. The emergency action plan will be led by the Mexican government and supported by a consortium of marine mammal experts from more than a dozen organizations around the world.
Despite substantial efforts by the Mexican government to protect vaquitas, the recovery team recently reviewed the latest results from advanced acoustic monitoring technology that showed the vaquita population continuing to rapidly decline.
“We are watching this precious native species disappear before our eyes,” said Rafael Pacchiano, Mexico’s secretary of the environment and natural resources. “This critical rescue effort is a priority for the Mexican government and we are dedicated to providing the necessary resources in order to give the plan its best chance of success.” The plan will be implemented in tandem with ongoing efforts to remove the threat of gillnets in the Upper Gulf of California and eliminate illegal fishing.

Ocean animals along the Atlantic coast of the U.S. will remain safe from excessive noise pollution at least for the foreseeable future, as President Obama last week moved to deny six permit applications for oil and gas exploration from Florida to Delaware — including requests to use intrusive seismic blasting.
