Caltech Researchers Use Stalagmites To Study Past Climate Change
2012-05-04 05:39:29

There is an old trick for remembering the difference between stalactites and stalagmites in a cave: Stalactites hold tight to the ceiling while stalagmites might one day grow to reach the ceiling. Now, it seems, stalagmites might also fill a hole in our understanding of Earth's climate system and how that system is likely to respond to the rapid increase in atmospheric carbon dioxide since preindustrial times. Many existing historical climate records are biased to the high latitudes–...

Gulf Oil Spill Seriously Impacted Deep-sea Corals: Study
2012-03-27 07:34:00

Scientists reported on Monday that they have found “compelling evidence” that the Deepwater Horizon oil spill in the Gulf of Mexico has seriously impacted deep-sea corals. "These biological communities in the deep Gulf of Mexico are separated from human activity at the surface by 4,000 feet of water,” she said,” said Helen White, Assistant Professor of Chemistry at Haverford College and lead author of the study. “We would not expect deep-water corals to be...

Glacier Cores From Eastern European Alps May Yield New Climate Clues
2012-01-10 05:41:00

Researchers are beginning their analysis of what are probably the first successful ice cores drilled to bedrock from a glacier in the eastern European Alps. With luck, that analysis will yield a record of past climate and environmental changes in the region for several centuries, and perhaps even covering the last 1,000 years.  Scientists also hope that the core contains the remnants of early human activity in the region, such as the atmospheric byproducts of smelting metals. The...

Coral reefs are among the most diverse ecosystems on the planet, second only to tropical rain forests. Bird's nest coral (Seriatopora hystrix) is common throughout the Indo-Pacific and is able to live across a range of depths. However, there is little gene flow between the coral populations at each depth and even the algal endosymbionts (Symbiodinium), which provide energy for the corals to survive, are genetically different across habitats. New research published in BioMed Central's open...

A group of researchers have studied the history of drought in the Pacific Northwest during the last 6,000 years, a time that spans the mid-Holocene geological epoch to the present. The goal of the research was to improve the understanding of drought history because the instrumental record of drought only goes back a few hundred years and at relatively few locations. Their work extended the drought history of the Pacific Northwest back much longer than the tree ring record, which provides...

New research reveals that weather-battered northern Australia could be in for more extreme weather events. Researchers studied coral cores that reveal a centuries-old climate record for the region, according to a recent Reuters report Corals can help scientists go back in time by revealing years that were unusually wet or dry.  The annual changes or variations in weather are recorded in growth rings that can be studied by drilling and extracting long cores. "The corals are providing...

The world's corals not only display stunning beauty and diversity "“ they also have rhythm, man. And that helps to keep them going through the lonely low-­"point of the night, when their partner robs them blind. That corals, among the simplest of Earth's creatures, have some curiously human-­"like attributes is emerging in a fresh set of revelations from by an international team of Australian and Israeli coral geneticists at...

Scientists in Australia have found a cluster of dazzling shallow-water corals that could help with the production of possible cancer-fighting drugs and may help to understand global warming, a researcher frmo the University of Western Sydney said Saturday. The fluorescent cluster of corals was found off Lord Howe Island, 400 miles east of the Australia. Some displayed rich reds that proved hard to find and are in high demand for cancer cell studies, said researcher Anya Salih. The...

Glaciologists who drilled through an ice cap perched precariously on the edge of a 16,000-foot-high Indonesian mountain ridge say that the ice field could vanish within in the next few years, another victim of global climate change. The Ohio State University researchers, supported by a National Science Foundation grant and the Freeport-McMoRan mining company and collaborating with Meteorological, Climatological and Geophysical Agency (BMKG) Indonesia and Columbia University, drilled three ice...

Biologist Mikhail Matz uses next-generation sequencers and a massive, NSF-supported supercomputer to study corals at the genomic level and look for evolutionary changes Our oceans are getting warmer and more acidic every year; as a result, coral reefs are rapidly declining. Biologist Mikhail Matz is monitoring this process at the genomic level, in anticipation of evolutionary developments that may signal better news. "Corals have a substantial potential to evolve, and this is the high time...

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...
