New research, which reconstructs the extent of ice in the sea between Greenland and Svalbard from the 13th century to the present indicates that there has never been so little sea ice as there is now. The research results from the Niels Bohr Institute, among others, are published in the scientific journal, Climate Dynamics.There are of course neither satellite images nor instrumental records of the climate all the way back to the 13th century, but nature has its own 'archive' of the climate...

The thought of coral reefs tends to conjure up images of tropical vacations, complete with snorkeling among tropical fish in crystal clear waters.Rapid climate change, and increased pollution, ocean acidification and overfishing threaten to darken this picture considerably. These factors heavily stress corals, and thus put both the countless marine organisms that count on corals for habitat and shelter, and the $1 billion dollar tourism industry fueled by coral reefs at significant...

Two abrupt and drastic climate events, 700 years apart and more than 45 centuries ago, are teasing  scientists who are now trying to use ancient records to predict future world climate. The events "“ one, a massive, long-lived drought believed to have dried large portions of Africa and Asia, and the other, a rapid cooling that accelerated the growth of tropical glaciers "“ left signals in ice cores and other geologic records from around the world. Lonnie Thompson, University...

U.S. scientists have used deep ocean sediment to reconstruct an ancient climate record dating to more than 500,000 years. Ohio State University researchers said the sediment -- trapped within the top 65.6 feet of a 1,312-foot sediment core drilled in 2005 in the North Atlantic Ocean -- has provided new information about the four glacial cycles that occurred during that period. We've now generated a climate record from this core that has a very high temporal resolution, one that is...

When the climate warmed relatively quickly about 14,700 years ago, seasonal monsoons moved southward, dropping more rain on the Earth's oceans at the expense of tropical areas, according to climate researchers. If the same pattern occurs in the coming decades as the Earth's temperatures rises due to climate change, the highly-populated regions of the world that depend on monsoons could face more wildfires, water shortages and lower agricultural production.In an article to be published in the...

Scientists identified seven new species of bamboo coral discovered on a NOAA-funded mission in the deep waters of the Papahānaumokuākea Marine National Monument. Six of these species may represent entirely new genera, a remarkable feat given the broad classification a genus represents. A genus is a major category in the classification of organisms, ranking above a species and below a family. Scientists expect to identify more new species as...

A research team returned from a month long underwater voyage that shed the light on never before seen species of fish and the effects of climate change in the deepest areas of the ocean. Scientists from the California Institute of Technology and an international team of collaborators traveled around Tasmania, Australia with a 502-pound video camera. The Eye-in-the-Sea is part of a new brand of scientific investigation to evaluate how global warming affects marine life. "It was truly one of...

Cooperative agreements signed with teams from the University of Wisconsin, Dartmouth College, University of New Hampshire are vital to climate studies The National Science Foundation (NSF)'s Office of Polar Programs (OPP) announced today the signing of cooperative agreements, one with a university collaboration comprising Dartmouth College, the University of New Hampshire, and the University of Wisconsin-Madison, and the other with the University of Wisconsin-Madison alone, that together...

The discovery of two species of coral once thought to be extinct provide an important link between the Atlantic and Pacific oceans, U.S. scientists said. The U.S. scientists -- Ann Budd from the University of Iowa and Donald McNeill of the University of Miami -- and Carden Wallace of the Museum of Tropical Queensland, Australia, sampled 67 locations around Curacao, Netherlands Antilles, and found the Isopora ginsburgi and Isopora curacaoensis. Until the discovery, the coral genus Isopora was...

Nephtheidae is a family of soft corals known as carnation corals, tree corals or colt soft corals. These corals are very striking and show a wide range of rich colors including red, pink, yellow and purple. These corals are mainly tree-like in that they branch out and have little knobs on the end of their rubbery branches. Another name given these animals are broccoli corals, due to the fact that their polyps retract in the daytime, giving them the resemblance of the vegetable. The polyps...

Fungia scutaria is a species of mushroom coral in the family Fungiidae. It is found in the Indo-Pacific oceanic region. It occurs on upper reef slopes especially where there is considerable water movement. It is typically found on sand beds or coral fragments. It lives as a single individual rather than as a colony and is detached from the seabed. It has an elongated shape and can grow quite large. The polyp can be up to 6.7 inches long and is embedded in a cup-shaped hollow known as a...

Astrocoeniidae is a family of stony corals endemic to the waters around Papua New Guinea and northern Australia. Their habitats are steep slopes where strong currents rise from below, in crevices and below overhangs. These are reef-building colonial corals containing an algae known as zooxanthallae. These algae typically encrust corals up to 20 inches in diameter. On reef slopes, where water is more turbid (cloudy/murky), they are much smaller, only reaching 2 inches across. The World...

Alcyoniidae is a family of leathery corals that occur globally in temperate and tropical seas. These reef dwellers are often found in wave-exposed areas of reef crests, less turbid waters in lagoons, on steep slopes, under overhangs, and at depths of 100 feet and deeper. A colony of leathery coral is stiff, hard, and inflexible. It is composed of tiny polyps projecting from a shared leathery tissue. There are two kinds of polyps seen in Alcyoniidae corals: autozooids have long trunks and...
