A Plan to Mute Ocean Noise for Marine Life
June 15, 2016 06:37 AM - Laura Goldman, Care2

Imagine trying to relax in your home while being bombarded with the explosive sounds of shotgun blasts as well as freight trains rumbling by. For many whales, dolphins and other marine life that depend on their hearing to survive, there is no way to escape the loud, human-made noises in their ocean home. The main culprits are vessels like cargo ships, along with sonar guns used by the U.S. Navy and air guns used in seismic oil and gas exploration. Their blasts are so loud that they are known to change the behavior of blue whales. But now, in what Michael Jasny, director of the Natural Resources Defense Council’s Marine Mammal Protection Project, Land & Wildlife Program, referred to as “a sea change in the way we manage ocean noise off our shores,” NOAA has announced it plans to take action to reduce the noise in entire marine ecosystems.

CDC publishes new map showing US locations of potential Zika-carrying mosquitoes

A few months ago, the Centers for Disease Control and Prevention published a startling map that showed the parts of the U.S. that could harbor mosquitoes capable of carrying Zika. The map made it look like a vast swath of the country was at risk for Zika, including New England and the Upper Midwest. Well, not quite. On Thursday, CDC scientists published another mosquito map for the U.S. And it paints a very different picture.

Popcorn-like fossils provide evidence of environmental impacts on species numbers
June 10, 2016 04:31 PM - University of Southampton via ScienceDaily

The number of species that can exist on Earth depends on how the environment changes, according to new research led by the University of Southampton.

By analysing the fossil record of microscopic aquatic creatures called planktonic foraminifera, whose fossil remains now resemble miniaturised popcorn and date back millions of years, the research provided the first statistical evidence that environmental changes put a cap on species richness.

NOAA, USGS, partners predict an average 'dead zone' for Gulf of Mexico
June 10, 2016 10:53 AM - NOAA Headquarters

Scientists forecast that this year's Gulf of Mexico dead zone--an area of low to no oxygen that can kill fish and marine life - will be approximately 5,898 square miles or about the size of Connecticut, the same range as it has averaged over the last several years.

Is sunscreen bad for coral reefs?
June 10, 2016 07:01 AM - Natalia Lima, Care2

You only use a little bit of sunscreen — a squeeze of the bottle or two or three sprays. Sure, it has some chemical ingredients, but it won’t kill anyone, right? Wrong. Sunscreen is actually one of the culprits of putting over 60 percent of the planet’s coral reefs in critical danger — and bringing a whole lot of other wildlife down with them.

The role of dam removal in river management in New England
June 9, 2016 01:48 PM - Dartmouth College via ScienceDaily.

Dam removal in New England is not only an important aspect of river restoration but it also provides an opportunity to enhance the magnitude and rate of river re-connection, and improve watershed resilience in response to human impact on the environment, if a broader strategic removal approach is implemented throughout the region, according to a new Dartmouth-led study published in Elementa: Science of the Anthropocene.

The study is the first interdisciplinary, region-wide assessment of the social and biophysical impacts of dam removal and was conducted by researchers at Dartmouth, American Rivers and the USDA Forest Service.

 

Not So Healthy: Young Fish Eat Microplastics Like Fast Food
June 6, 2016 05:06 PM - Steve Williams, Care2

New research shows that young fish are eating tiny pieces of plastic instead of their regular food — with potentially devastating consequences.

A study published this month in the journal “Science” explains that juvenile perch larvae appear to be eating microplastics in place of their usual food sources, like free-swimming zooplankton. This hinders fish development, leaving them more susceptible to predators.

Microplastics — plastic particles that measure below 5mm — infiltrate our environments as a result of litter, such as plastic bags, packaging and other materials, that eventually end up in the sea. Microbeads — tiny plastics often found in health products, such as face scrubs and even some toothpastes — represent another major source of pollution. For this reason, a number of governments have either banned or are considering banning microbeads.
