Lee Siegel, University of Utah Global warming may bring more curvy jet streams during winter Last winter's curvy jet stream pattern brought mild temperatures to western North America and harsh cold to the East. A University of Utah-led study shows that pattern became more pronounced 4,000 years ago, and suggests it may worsen as Earth's climate warms. "If this trend continues, it could contribute to more extreme winter weather events in North America, as experienced this year with...

MIAMI, April 15, 2014 /PRNewswire-USNewswire/ -- Miami could know as early as 2020 how high sea levels will rise into the next century, according to a team of international researchers including FIU Earth and Environment Professor Rene Price. Sea level rise is one of the most certain consequences of climate change. But the speed and long-term height of the rise is one of the great scientific unknowns. Some scientists believe sea level rise is accelerating, some suggest the rate is...

What Lives In The Deepest Part Of The Ocean?
2014-04-11 11:44:48

National Science Foundation "Telepresence" capability will bring mysteries of The Deep to the computer screen A team of researchers funded by the National Science Foundation (NSF) will use the world's only full-ocean-depth, hybrid, remotely-operated vehicle, Nereus, and other advanced technology to find out. They will explore the Kermadec Trench at the bottom of the Pacific Ocean. The trench, located off New Zealand, is the fifth deepest trench in the world. Its maximum depth is...

Reef Fish Arrived In Two Waves
2014-04-11 10:11:10

University of California, Davis The world's reefs are hotbeds of biological diversity, including over 4,500 species of fish. A new study shows that the ancestors of these fish colonized reefs in two distinct waves, before and after the mass extinction event about 66 million years ago that wiped out the dinosaurs. Reef fish represent one of the largest and most diverse assemblages of vertebrates, according to Samantha Price, a postdoctoral researcher in the Department of Evolution and...

Titanic Sailing Conditions Were Not As Extreme As Modern Day
2014-04-11 09:01:42

Brett Smith for redOrbit.com - Your Universe Online One hundred and two years ago this week, the Titanic set off on its fateful maiden voyage from the United Kingdom. Coinciding with that anniversary is a new report from British researchers who have determined the conditions surrounding the iceberg that would eventually take 1,517 lives. According to the report, which was published in the journal Weather, 1912 was not an exceptionally high year for icebergs – particularly in light of...

The extreme cold weather observed across Europe and the east coast of the US in recent winters could be partly down to natural, long-term variations in sea surface temperatures, according to a new study published today. Researchers from the University of California Irvine have shown that a phenomenon known as the Atlantic Multidecadal Oscillation (AMO)—a natural pattern of variation in North Atlantic sea surface temperatures that switches between a positive and negative phase every 60-70...

Chilean M8.2 Earthquake May Be Forewarning Of A Larger Event
2014-04-02 07:51:51

Lawrence LeBlond for redOrbit.com - Your Universe Online Chile is beginning to dig out from a massive 8.2 magnitude earthquake that struck the region at 8:46 p.m. local time Tuesday evening about 52 miles northwest of the mining town of Iquique, according to the USGS. At least five people are confirmed dead and tens of thousands have been evacuated from their homes. The earthquake touched off tsunami warnings and, according to the BBC, waves up to six feet battered the shoreline in some...

Test shows it could have accurately forecasted flooding in NYC during Sandy The water that surged into the intersection of New York City’s Canal and Hudson streets during Hurricane Sandy—to choose just one flood-ravaged locale—was ultimately driven ashore by forces swirling hundreds of miles out in the Atlantic. That simple fact shows not only the scale and power of a tropical cyclone, but the difficulty of modeling and forecasting its potential for coastal flooding on the fine...

HOBO® U22 Data Loggers Monitor Potentially Damaging Increases in Local Sea Temperature and Determine Effects on Coral Bourne, MA (PRWEB) March 25, 2014 At Naitauba, Fiji, a 2,000-acre island completely encircled by a coral reef, the Naitauba Reef Initiative is working with researchers from the University of the South Pacific (USP) School of Marine Studies to learn as much as possible about all aspects of the reef. Onset’s HOBO U22 Water Temperature Pro v2 data loggers are being...

El Nino Forecast A Sign Of Relief For Drought-Stricken Californians
2014-03-07 10:37:54

Brett Smith for redOrbit.com - Your Universe Online California residents plagued by drought just got some good news from the National Oceanic and Atmospheric Administration (NOAA): El Niño is coming – maybe. El Niño is a weather-generating phenomenon based on the surface water temperatures off the western coast of South America and NOAA’s long-range forecast has said there is about a 50-50 chance that it will form this summer or fall – potentially bringing wetter weather to the...

Coral Reef
2013-04-20 15:49:21

Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...

Current Sea Level Rise
2013-04-01 10:39:21

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...

Basic Ocean Terms
2013-02-05 12:52:11

Image Credit: Meteorologist Joshua Kelly When meteorologists are forecasting for ocean-going vessels, there are a few terms that we need to understand. The first term is wavelength. Wavelength is defined as the distance between two crests or between two troughs as seen in the image above. The example above highlights the crest to crest concept of wavelength. The next term that we use is wave height, and to determine this, we first must look at the wave when it passes our station. When...

Climate Impact On Your Budget For Billings Montana
2012-12-29 12:40:14

If you live in or around Billings, Montana the above graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. In Billings during a normal phase of the ENSO your heating degree days pass 900HDD. However, when El-Nino phase is present the monthly average dropped to around 650.5HDD, which is a pretty significant amount especially when you are talking about paying that heating bill. When the La-Nina phase sets up the heating degree...

Climate Impact On Your Budget For Bismarck, North Dakota
2012-09-18 13:29:03

If you live in or around Bismarck North Dakota the graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. Bismarck North Dakota, with its northern latitude, does have an impact on what type of heating and cooling it sees. During an Normal Phase the HDD for the region hits about 1348 on average. When the region enters into an El-Nino they can expect the amount of HDD’s to decrease to around 970 which really helps cut down on the...
