Busy Microbial World Discovered in Deepest Ocean Crust Ever Explored

microbial life interactions going on in the deepest ocean crust ever explored!

The first study to ever explore biological activity in the deepest layer of ocean crust has found bacteria with a remarkable range of capabilities, including eating hydrocarbons and natural gas, and “fixing” or storing carbon.

Reverse Circulation in Atlantic Ocean

this wil make your toilet spin the other direction upon a flush. Fear not.

Universitat Autònoma de Barcelona scientists have researched how ocean currents in the Atlantic were affected by climate change in the past. The study shows that there was a period when the flow of deep waters in the Atlantic was reversed. The results are relevant for the near future since similar changes are expected to occur in the course of climate warming over the next 100 years.

Upside-Down Answer for Deep Mystery: What Caused Earth to Hold Its Last Breath?

100217131140-large

Volcano eruption

When Earth was young, it exhaled the atmosphere. During a period of intense volcanic activity, lava carried light elements from the planet’s molten interior and released them into the sky. However, some light elements got trapped inside the planet. In the journal Nature, a Rice University-based team of scientists is offering a new answer to a longstanding mystery: What caused Earth to hold its last breath?

This is Prussian blue. This salt could cause substances essential for life.

A team of researchers from the Astrobiology Centre (INTA-CSIC) has shown that hydrogen cyanide, urea and other substances considered essential to the formation of the most basic biological molecules can be obtained from the salt Prussian blue. In order to carry out this study, published in the journal Chemistry & Biodiversity, the scientists recreated the chemical conditions of the early Earth.

African Desert Rift Confirmed As New Ocean In The Making

New research confirms that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world’s oceans, and the rift is indeed likely the beginning of a new sea.

In 2005, a gigantic, 35-mile-long rift broke open the desert ground in Ethiopia. At the time, some geologists believed the rift was the beginning of a new ocean as two parts of the African continent pulled apart, but the claim was controversial.

Tsunami Waves Reasonably Likely To Strike Israel, Geo-archaeological Research Suggests

Ancient port city of Caesarea, Israel.

“There is a likely chance of tsunami waves reaching the shores of Israel,” says Dr. Beverly Goodman of the Leon H. Charney School of Marine Sciences at the University of Haifa following an encompassing geo-archaeological study at the port of Caesarea. “Tsunami events in the Mediterranean do occur less frequently than in the Pacific Ocean, but our findings reveal a moderate rate of recurrence,” she says.

Banded Rocks Reveal Early Earth Conditions, Changes

091011184428

Pictured in 2008, a banded iron formation about 2.5 billion years old near Soudan Underground Mine State Park in Minnesota shows alternating layers of silica-rich (red) and iron-rich (gray) minerals.

The strikingly banded rocks scattered across the upper Midwest and elsewhere throughout the world are actually ambassadors from the past, offering clues to the environment of the early Earth more than 2 billion years ago. Continue reading… “Banded Rocks Reveal Early Earth Conditions, Changes”

Largest Dinosaur Footprints Ever Found Discovered Near Lyon, France

091009132928

Plagne site where sauropod dinosaur tracks were discovered. September 2009.

Footprints from sauropod dinosaurs, giant herbivores with long necks, were found in Plagne, near Lyon, France. Discovered by Marie-Hélène Marcaud and Patrice Landry, two nature enthusiasts, the dinosaur footprints have been authenticated by Jean-Michel Mazin and Pierre Hantzpergue, both of the Paléoenvironnements et Paléobiosphères laboratory

Ancient Earth’s Magnetic Field Was Structured Like Today’s Two-pole Model

091002132350

The well-exposed layering of basalt flows in formations near Lake Superior is aiding scientific understanding of the geomagnetic field in ancient times. Nicholas Swanson-Hysell, a Princeton graduate student, examines the details of the top of a lava flow.

Princeton University scientists have shown that, in ancient times, the Earth’s magnetic field was structured like the two-pole model of today, suggesting that the methods geoscientists use to reconstruct the geography of early land masses on the globe are accurate. The findings may lead to a better understanding of historical continental movement, which relates to changes in climate.

Super-computer Provides First Glimpse Of Earth’s Early Magma Interior

Earth…

By using a super-computer to virtually squeeze and heat iron-bearing minerals under conditions that would have existed when the Earth crystallized from an ocean of magma to its solid form 4.5 billion years ago, two UC Davis geochemists have produced the first picture of how different isotopes of iron were initially distributed in the solid Earth.
