Alligators on the beach? Killer whales in rivers? Get used to it

Excerpts;

Sightings of alligators and other large predators in places where conventional wisdom says they ‘shouldn’t be’ have increased in recent years, in large part because local populations, once hunted to near-extinction, are rebounding.

A new article finds that far from being outliers, these sightings signify the return of highly adaptable predators to prime hunting grounds they occupied long ago — a trend that opens new opportunities for future conservation…

Growing ‘dead zone’ confirmed by underwater robots in the Gulf of Oman

Excerpts;

New research reveals a growing ‘dead zone’ in the Gulf of Oman. Little data has been collected in the area for almost 50 years because of piracy and geopolitical tensions. The area devoid of oxygen was confirmed by underwater robots. Reasearchers found an area larger than Scotland with almost no oxygen left.

The environmental disaster is worse than expected with dire consequences for fish and marine plants, plus humans who rely on the oceans for food and employment…

County Starts Dumping-Related Clean-up Work at Goleta, Carpinteria Beaches; CA


As of January 12th, 2018, approximately 800 cubic yards has been transported to Goleta Beach, California. Photo courtesy of: © Adam Hogue, Shani Asayag & Vanessa Lytle, Santa Barbara High School Seniors, MAD Academy.

Excerpts;

Truckloads of mud from debris flow removal was transported to local beaches following Montecito debris flow.

Two months after trucks stopped dumping loads of Montecito mud onto the shore at Goleta Beach County Park, the ocean waters remain closed because testing shows bacteria levels significantly exceed standards.

Ocean waters are closed if they have been contaminated by fecal bacteria or raw sewage, and they will stay closed until sampling results show the water meets state health standards, according to the county Public Health Department.

There are red warning signs posted along the beach, and Public Health also advises people to avoid eating raw fish and shellfish caught close to ocean waters with elevated bacteria levels…

Mapping Beach Changes After Devastating Montecito Debris Flows, USGS (03-26-2018)
During the week of March 26, scientists from the U.S. Geological Survey carried out four days of mapping selected beaches and the adjacent seafloor in Santa Barbara and Ventura counties. Results will be compared to surveys from last fall to highlight changes due to winter waves, and to sediment inputs from area streams…

Trucking Mud to the Beaches Means More Sand but Dirtier Waters, CA; Santa Barbara Independent (02-08-2018)
When Santa Barbara County dumps tons of mud from the catastrophic debris flow of January 9 on the shores of Goleta and Carpinteria, this wasn’t like anything that’s happened before. So residents are asking, “Will there be long-term effects? Might there be other locations that can share the impacts..?”

Estuaries may experience accelerated impacts of human-caused CO2

Excerpts;

Rising anthropogenic, or human-caused, carbon dioxide in the atmosphere may have up to twice the impact on coastal estuaries as it does in the oceans because the human-caused CO2 lowers the ecosystem’s ability to absorb natural fluctuations of the greenhouse gas, a new study suggests…

Dolphins tear up nets as fish numbers fall

greenpeace-dolphins-trawler
“As the super trawler Margiris steams towards Australia’s shores, a series of concerns have been raised. One is the impact on marine life, like dolphins and seals, that invariably are caught in the vessel’s enormous nets. These pix were taken by researchers on board Dutch super trawlers while conducting peer-reviewed studies.” August, 2012. Captions and Photo source: © Greenpeace

Excerpts;

University of Exeter researchers studied the impact of bottlenose dolphins on fisheries off northern Cyprus and said Mediterranean overfishing had created a “vicious cycle” of dolphins and fishers competing for dwindling stocks.

The researchers estimate that about ten dolphins are accidentally caught in the study area each year, but under-reporting by fishermen and possible deaths due to swallowing plastic from nets may mean this is an under-estimate…

Inability of phytoplankton to acquire iron imperils marine ecosystems.

A team led by scientists from Scripps Institution of Oceanography at the University of California San Diego and the J. Craig Venter Institute (JCVI) has demonstrated that the excess carbon dioxide added to the atmosphere through the combustion of fossil fuels interferes with the health of phytoplankton which form the base of marine food webs…

Phytoplankton are microscopic plants whose growth in ocean surface waters supports ocean food webs and global marine fisheries. They are also key agents in the long-term removal of carbon dioxide (CO2)…
