In First, NASA Probe Detects 'Alien Matter' Entering Our Solar System (VIDEO)

Two hundred thousand miles (322,000 km) above the earth, the Interstellar Boundary Explorer (IBEX) drifts in space, quietly “sniffing” the interstellar wind that continuously streams into our solar system from far beyond. The probe is designed to detect minute traces of matter (electrically neutral atoms and molecules, know as interstellar material) that originated in supernovae

Oxygen-Free Oceans Wrought Changes on Early Earth

Geologists at the University of California, Riverside, have discovered chemical evidence that indicates Earth’s ancient oceans were not only oxygen-free, but also contained large quantities of hydrogen sulphide in some areas. “We are the first to show that ample hydrogen sulfide in the ocean was possible this early in Earth’s history,” said Timothy Lyons, a

Lack of Oxygen Challenged Early Life on Earth

Earth’s oceans are teeming with life thanks to the oxygenated waters which allow that life to grow and thrive: just as animals on land need oxygen to survive, so too do the fish and mammals beneath the sea surface. However around 499 million years ago the oceans suffered an event which turned them into a

An Ice-Free Arctic Ocean Will Not Absorb More CO2

An international team of climate and ocean scientists, led by Wei-Jun Cai (U of Georgia, Athens), predicts that the “Arctic Ocean basin will not become a large atmospheric CO2 sink under ice-free conditions.” Using data from a 2008 high-resolution survey of the entire Canada Basin, the team explains the complex “air-sea flux” and other reasons why sea-surface CO2 continues to increase.

World's Marine Plankton in Peril – 40% Decline Since 1950

Phytoplankton–tiny, marine plants that formthe basis of our oceans’ food chain–absorb and sequester large amounts of CO2 from the atmosphere and generate half of the world’s oxygen supply. Given such an important ecosystem service as this, one would hope that our oceans’ algae numbers stay high…but, the results of a three year data analysis are anything but encouraging.

Baltic Sea "Dying" from Lack of Oxygen

It’s not only the Gulf of Mexico that’s suffering from “dead zones” caused by  excess nutrients, such as nitrogen and phosphorus used as fertilizers. Marine dead zones are spreading in the Baltic sea, and that could cause the entire ecosystem to collapse for lack of oxygen.  Dire warnings from Lasse Gustavsson, Swedish head of the
