The discovery of 160 year old records in the archives of the Royal Society, London, has given scientists further evidence that Australian sea levels are rising.

Observations taken at Tasmania’s Port Arthur convict settlement 160 years ago by an amateur meteorologist have been compared with data from a modern tide gauge.

“There is a rate of sea level rise of about 1mm a year, consistent with other Australian observations,” says Dr David Pugh, from the UK’s Southampton Ocean

Promising cancer-fighting candidates emerge from tropical ocean ‘mud’

Although the oceans cover 70 percent of the planet’s surface, much of their biomedical potential has gone largely unexplored. Until now.

A group of researchers at Scripps Institution of Oceanography at the University of California, San Diego, have for the first time shown that sediments in the deep ocean are a significant biomedical resource for microbes that produce antibiotic molecules.

Findings detailed in Jan. 16 issue of Nature; greenhouse gases implicated

A study by University of Massachusetts Amherst geoscientist Robert DeConto posits an alternative theory regarding why Antarctica suddenly became glaciated 34 million years ago. The study challenges previous thinking about why the ice sheet formed and holds ramifications for the next several hundred years as greenhouse gases continue to rise. DeConto, who collaborated with David Pollard of Pennsylvania State Univ

Climate change had little to do with the demise of the dinosaurs, but the last million years before their extinction had a complex pattern of warming and cooling events that are important to our understanding of the end of their reign, according to geologists.

“The terrestrial paleoclimate record near the K-T is historically contradictory and poorly resolved,” says Dr. Peter Wilf, assistant professor of geosciences at Penn State. “In contrast, the resolution of K-T marine climates that has

Local fisheries part of bigger cycle affecting entire Pacific Ocean

In the late 1930’s, California’s sardines supported the biggest fishery in the western hemisphere, with more than half a million tons of fish caught each year. By the mid-1950s, the sardines had virtually disappeared. Although fishing pressure may have played a part in this process, new research published in the current issue of Science indicates that the sardines’ demise was part of a 50-year cycle tha

Using a state-of-the-art computer model of the lunar interior, geophysicists at the University of California, Berkeley, have shown that a mighty burp early in the moon’s history could account for some of its geologic mysteries.

The burp of hot rock, like a blob rising to the top of a lava lamp, would have lifted a blanket covering the moon’s core, allowing the core to cool quickly enough to produce a magnetic field.

The moon has long since cooled off and the global magne
