Locked in Arctic Soils Into the Ocean, Researchers Say The Arctic Ocean receives about ten percent of Earths river water and with it some 25 teragrams [28 million tons] per year of dissolved organic carbon that had been held in far northern bogs and other soils. Scientists had not known the age of the carbon that reaches the ocean: was it recently derived from contemporary plant material, or had it been locked in soils for hundreds or thousands of years and therefore not part of
Period was previously thought to be ice-free
Arlington, Va.-Scientists using cores drilled from the New Jersey coastal plain have found that ice sheets likely caused massive sea level change during the Late Cretaceous Period -an interval previously thought to be ice-free. The scientists, who will publish their results in the March-April issue of the Geological Society of America (GSA) Bulletin, assert that either ice sheets grew and decayed in that greenhouse world or our understandin
The Mediterranean Sea was a desert, millions of years ago. In contrast, the Sahara Desert was once a lush, green landscape dotted with lakes and ponds. Evidence of this past verdancy lies hidden beneath the sands of Egypt and Libya, in the form of a huge aquifer of fresh groundwater. An international team of geologists and physicists has found that this groundwater has been flowing slowly northward (at about the rate grass grows) for the past million years. Their findings have been accepted for March
Scientists at international conference release strategy to save them
The leatherback turtle, a gentle giant weighing close to a ton (907 kg) and measuring eight feet (2.4 meters) in length, may be extinct within a decade in the Pacific Ocean.
The news was released at the 24th Annual Symposium on Sea Turtle Conservation and Biology, a weeklong conference in San Jose, Costa Rica attended by more than 1,000 experts from 70 countries.
Named for its smooth, leathery ski
Provides new look at conservation of threatened coral species
An international research team has identified a family of corals found only in the Atlantic Ocean-a first for such classifications in that ocean-in a study that could transform how corals are viewed and classified. The scientists, who will publish their results in the Feb. 26 issue of the journal Nature, say the findings are also important for future decisions about coral conservation and the preservation of threatened biod
“Nature was nano before nano was cool,” stated Henry Fountain in a recent New York Times article on the proliferation of nanotechnology research projects. No one is more aware of this fact of nature than Dan Morse of the University of California, Santa Barbara. His research groups have been studying the ways that nature builds ocean organisms at the nanoscale for over ten years.
For example, they have studied the abalone shell for its high-performance, super-resistant, composite mineral str
