Deep Sea Currents may be Slowed by Climate Change

Ocean currents act as conveyor belts that channel heat, carbon, oxygen and other nutrients around the world's seas, and the slowdown of deep sea currents is worrisome, scientists say.

Diving shrews: Heat before you leap

How does the world's smallest mammalian diver survive icy waters to catch its prey? A recent study of American water shrews has surprised researchers by showing that the animals rapidly elevate body temperature immediately before diving into cold water.

Fish learn to cope in a high carbon dioxide world, new study suggests

Some coral reef fish may be better prepared to cope with rising carbon dioxide in the world's oceans -- thanks to their parents. Encouraging new findings show that some fish may be less vulnerable to high CO2 and an acidifying ocean than previously feared.

Humans are primary cause of global ocean warming over past 50 years, research shows

Scientists have shown that the observed ocean warming over the last 50 years is consistent with climate models only if the models include the impacts of observed increases in greenhouse gas during the 20th century.

Oceanic circulation: Heat loss strengthens the gyre circulation

A new study explains decadal variations in the oceanic circulation south of Greenland and Iceland. 

New Ecological Model for Deep-Water Oil Spills

On the second anniversary of the Deepwater Horizon oil platform blowout, a national panel of researchers is providing new insight into what happened in the disaster, as well as a guide for how to deal with such events in the future, and why existing tools were inadequate to predict what lay before them.

Potential for a 'Moderate' New England 'Red Tide' in 2012 

 

New England is expected to experience a "moderate" regional "red tide" this spring and summer, report NOAA-funded scientists working in the Gulf of Maine to study the toxic algae that causes the bloom.

We can extract oil from our far south basin - here’s how

I've recently returned from the “Our Far South” trip to the Southern Ocean and Antarctica, a month-long journey led by Gareth Morgan and populated    with 49 other opinionated people, many of them scientists and industry experts. For me, the most pressing ...

USM sets sights on further research in Antarctica (2)

Universiti Sains Malaysia (USM) aims to help Malaysia become a major contributor to global knowledge and scientific research in the world's fifth largest continent (and the coldest in the world) Antarctica.

Tropical Cyclone Iggy to Pound Indian Ocean Coast for Another Three Days

The weather bureau on Friday warned that Tropical Cyclone Iggy would continue to pound the Indian Ocean coast, affecting areas in Java and Bali for at least the next three days.

NASA Study Solves Case of Earth's 'Missing Energy'

Two years ago, scientists released a study claiming that inconsistencies between satellite observations of Earth's heat and measurements of ocean heating amounted to evidence of "missing energy" in the planet's system. Where was it going? Or, they wondered, was something wrong with the way researchers tracked energy as it was absorbed from the sun and emitted back into space? An international team of atmospheric scientists and oceanographers set out to investigate the mystery.

River running under Antarctica's ice discovered

Though Antarctica has a varied topography including mountains and valleys and has been known to have massive lakes deep beneath the ice, the team of glaciologists and cryosphere specialists say finding running water in liquid form in the area they did ... 

NASA Infrared Satellite Instrument Sees Tropical Storm Iggy Growing in Strength

The AIRS infrared instrument that flies on NASA's Aqua satellite has been providing forecasters with the cloud top temperatures in the Southern Indian Ocean's ninth tropical cyclone, which has officially been renamed Iggy. AIRS data showed that the area of strong thunderstorms around Iggy's center has expanded in area over the last day.

Scientists detect large build-up of water in the Arctic Ocean

 

Scientists at University College London and the UK’s National Oceanography Centre have discovered that a large dome of water has been building up in the western Arctic Ocean over the past 15 years.

Multiple Partners Not the Only Way for Corals to Stay Cool

For the first time scientists have shown that corals hosting a single type of zooxanthellae can have different levels of thermal tolerance – a feature that was only known previously for corals with a mix of zooxanthellae. This finding is important because many species of coral are dominated by a single type of zooxanthellae.

NASA sees repeating La Niña hitting its peak

La Niña, "the diva of drought," is peaking, increasing the odds that the Pacific Northwest will have more stormy weather this winter and spring, while the southwestern and southern United States will be dry. Sea surface height data from NASA's Jason-1 and -2 satellites show that the milder repeat of last year's strong La Niña has recently intensified, as seen in the latest Jason-2 image of the Pacific Ocean.

Ice Age Findings Forecast Problems: Data from End of Last Ice Age Confirm Effects of Climate Change On Oceans

The first comprehensive study of changes in the oxygenation of oceans at the end of the last Ice Age has implications for the future of our oceans under global warming. The study looked at marine sediment and found that that the dissolved oxygen concentrations in large parts of the oceans changed dramatically during the relatively slow natural climate changes at the end of the last Ice Age.

Strong quakes rattle remote Antarctica

Two strong earthquakes 40 minutes apart rocked the remote South Orkney Islands in Antarctica on Sunday, experts from the US Geological Survey said. The epicenter of the first, a magnitude 6.6 temblor, was at a depth of 10 kilometers (six ...

 Workshop on seismic hazard assessment

According to him, the country is under the threat of tsunamis from distant sources such as the Sunda-Java Trench in Indonesia and closer sources such as the Makran Subduction Zone in the northern Arabian Sea. In the first session, Dr Issa El Hussain ... 

Supraglacial lakes moving along Antartic ice shelf

Satellite images have revealed a sequence of lakes on top of the George VI ice shelf in Antarctica moving along the boundary of the ice shelf with Alexander Island. It was observed when LaBarbera and MacAyeal analyzed satellite images of ..

Joint Oceanography expeditions by Sri Lanka and China

This agreement marks a milestone in the Faculty of Fisheries and Marine Sciences and Technology of the University to engage in marine sciences and oceanography. The MoU has been signed by the Vice Chancellor of University of Ruhuna Senior Professor ...

UK & Australia. Acclaimed Metocean crourse comes to Perth

The effects of meteorology and oceanography (metocean) have a major impact on design and operations in all offshore industries. If users of metocean information are not aware of the implications that the weather, waves, currents and water levels can ...

   20,000 Robots Under the Sea

Jules Jaffe of the Scripps Institution of Oceanography is developing an army of underwater explorers that researchers hope will produce a fine-grained, real-time map of the movements of the sea. By Vince Beiser An artist's rendering of what the ...

Study Shows Health, Food Security Benefits from Climate Change Actions

A new study building on previous findings by scientists at Scripps Institution of Oceanography, UC San Diego, highlights 14 key air pollution control measures that if implemented could slow the pace of global warming, save millions of lives and boost ...
