Duck bill and echidna – are they our ancestors or relatives?

People, as they belong to the mammals, should be particularly interested in the problem of origin of this class in the animal kingdom that has conquered the entire world through evolution: not only the land, but, partly the ocean and the air. We have already known our ancient ancestors for long – these are medium-sized animals – eutherapsida (which means “real Synapsida”), they appeared at the end of the palaeozoic, approximately 270 million years ago, and continued to develop in the Age of

Scientists penetrate fossil magma chamber beneath intact ocean crust — achieving scientific ’first’

PACIFIC OCEAN, approximately 800 km west of Costa Rica¡ªAn international team of scientists aboard the research drilling ship JOIDES Resolution has¡–for the first time¡–recovered black rocks known as gabbros from intact ocean crust. Supported by the Integrated Ocean Drilling Program (IODP), the scientists drilled through the volcanic rock that forms the Earth’s crust to reach a fossil magma chamber lying 1.4 kilometers beneath the seafloor.

Geologists drill into fossil magma chamber deep under the ocean

International collaboration brings up first samples of hard rock called gabbro in intact ocean crust

Scientists aboard the research drilling ship JOIDES Resolution have, for the first time, drilled into a fossil magma chamber under intact ocean crust. There, 1.4 kilometers beneath the sea floor, they have recovered samples of gabbro: a hard, black rock that forms when molten magma is trapped beneath Earth’s surface and cools slowly.

Geologists: Opening of passage may be tied to Antarctic cooling

Ancient fish teeth are yielding clues about when Antarctica became the icy continent it is today, highlighting how ocean currents affect climate change.

University of Florida geologists have used a rare element found in tiny fish teeth gathered from miles below the ocean surface to date the opening of a passage at the bottom of the globe between the Atlantic and Pacific. The opening, which occurred millions of years ago in a much warmer era, allowed the formation of an ocean c

ERS-2 helps detect massive rivers under Antarctica

British scientists have discovered rivers the size of the Thames in London flowing hundreds of miles under the Antarctica ice shelf by examining small changes in elevation, observed by ESA’s ERS-2 satellite, in the surface of the oldest, thickest ice in the region, according to an article published in Nature this week.

The finding, which came as a great surprise to the scientists, challenges the widely held assumption that subglacial lakes evolved in isolated conditions for severa

Low cost internet access at sea

Through a project supported by the European Space Agency, the UK-based company Wired Ocean Ltd can now provide enhanced Internet access for ships at sea at a much lower cost than was previously possible.

Although satellite links at sea are quite common, the speed of data transmission for most users is very low, from 600 bps to 64 kbps, with around 10 kbps being a typical speed. This, combined with usage costs of around € 20 per megabyte, has created an environment in which many s
