12 Things I Found on the California Seafloor (and You Can Too)

by Elizabeth Preston in Inkfish

If for some reason you haven't been invited on a submersible ride-along, the next best thing is probably 340 miles' worth of raw video footage from the ocean floor.

The U.S. Geological Survey just released a whole mess of data from its California Seafloor Mapping Program. Together with many partners, it's working on building maps of the California coast that include seafloor depth, habitat type, and other geological features. There's also video footage from cameras towed a few feet above the........ Read more »

What’s Up with the Bad Chemistry?

by csoeder in Topologic Oceans

Watts Up With That is a very, very silly website. Here’s what I mean: In a recent article at WUWT, chemical engineering graduate Steve Burnette tries to dismiss concerns about ocean acidification, but his claims are outright wrong when they are coherent. The centerpiece of the article is a calculation meant to estimate the change […]... Read more »

Black Dog Syndrome: A Bad Rap?

by Cobb & Hecht in Do You Believe In Dog?

Hi Mia & Julie – Firstly, thanks so much for letting me drop a verse in the rap song of your blog! I feel so awesome being featured. It’s like being Lil Wayne or something. Anyway…I’m just recently back from ISAZ 2013, where I had a most excellent time chatting with other anthrozoologist-y types. As you know, I just graduated from the Anthrozoology Master’s Program at Canisius College, so I was uber-excited to have a chance to share my research with colleagues in the fiel........

Cottonmouths in the Ocean: Fact or Fiction?

by David Steen in Living Alongside Wildlife

           We know that some reptiles love the water. Alligators,
turtles, snakes, the swamps are crawling with them. But what about the ocean?
Are there any reptiles that use saltwater habitats?

            Of course. Sea turtles are well-known for spending their lives in the ocean (aside
from their brief trips to the beach to lay eggs). Not technically a sea turtle

Why Yellowstone's Grizzlies Should Be Grateful for Wolves

by Elizabeth Preston in Inkfish

There's only one time a giant domino chain isn't fun: when you're a domino. Humans are great knockers-down of ecosystem domino chains, and sometimes we don't even know which species we've felled until we start propping things back up. When we knocked every last wolf out of Yellowstone National Park, for example, we didn't know how we were hitting bears at the other end of the chain.

When Yellowstone was first created, visitors were free to kill the animals. Then in the early 20th century, go........ Read more »

What Comes First: The Signal or the Response?

by Miss Behavior in The Scorpion and the Frog

Jewel wasps show us how new communication systems may have come to be. Photo by M.E. Clark at Wikimedia Commons.Finding and attracting a mate is tricky business for most species. It can be quite helpful then to have a species-specific signal that is sent and received by members of your own species, but not perceived as well by predators. Chemical signals (those we perceive through smell and taste) are among the most diverse and specific signals produced in the animal kingdom, so they make good c........ Read more »

Biodiversity of Ecosystems Decrease in a High-CO2 Ocean

by Guillaume Cote-Maurais in United Academics

Climate change resulting from increased atmospheric carbon dioxide (CO2) and other greenhouse gases could also have other consequences.
Scientists are concerned that the absorption of atmospheric CO2 in the oceans could have an impact on marine ecosystems. This would result from absorption of atmospheric CO2, which causes a decrease in seawater pH and carbonate ion concentrations, while increasing CO2 and bicarbonate ion concentrations.... Read more »

4 Things Keystone XL Doesn't Have

by Whitney Campbell in Green Screen

For the past five years, the Keystone XL pipeline has been in the news. Since a permit to build it was first sought in 2008, the construction project has increasingly become iconic to environmental and energy groups alike. For many advocates, the pipeline is a tipping point toward an irrevocable future, a shift either disastrous or essential depending on one's beliefs about sustainable power.... Read more »

Arctic methane and global economy

by Perikis Livas in Tracing Knowledge

Ice melting releases methane stored in the form of hydrates in glaciers.
It has been estimated that there is a 50 gigatonne reservoir of methane on the East Siberian Arctic Shelf.

Researchers have for the first time calculated the potential economic impact of a scenario some scientists consider increasingly likely: that the methane below the East Siberian Sea will be emitted, either steadily over the next 30 years or suddenly and it will aggravate global economy as the estimated cost of miti........

Heavy Metals in Fish: Toxicity and Tolerance

by Melissa Chernick in Science Storiented

Today I found an interesting paper that fits right in to my new job in the field of aquatic ecotoxicology. As the name suggests, this field is a combination of ecology and toxicology that deals with the nature, effects, and interactions of harmful substances in the environment. In my case, it is aquatic, freshwater systems in particular. The paper I came across looks at the effects of metal contamination and tolerance in freshwater fish.Metal contamination is something that occurs worldwide. A n........ Read more »

Researchers Identify Best Microbial Species for Biofuel Production

by dailyfusion in The Daily Fusion

One of the keys to commercialization of advanced biofuels is the development of cost-competitive ways to extract fermentable sugars from lignocellulosic biomass. The use of enzymes from thermophiles—microbes that thrive at extremely high temperatures and alkaline conditions—holds promise for achieving this. Finding the most effective of these microbial enzymes, however, has been a challenge. That challenge has now been met by a collaboration led by researchers with the U.S. Departmen........

The Future Will Bring Hurricanes to Europe

by Reindert Haarsma. in United Academics

Damaging hurricanes are familiar along the US east coast, with the recent hurricane Sandy a dramatic example. In Europe we are unused to such dramatic weather and the widespread destruction that hurricanes can, and do, cause. However, our new research suggests that this is likely to change as Earth’s climate warms over the next century.

Hurricanes are powered by warm sea water and characterised by heavy rainfall. The energy that is released during this rainfall is the thriving force of ........ Read more »
