Predictions of sea level rise could become more accurate, thanks to new insight into how glacier movement is affected by melting ice in summer Predictions of sea level rise could become more accurate, thanks to new insight into how glacier movement is affected by melting ice in summer. Studies of the Greenland ice sheet, including during a record warm summer, are helping scientists better understand how summer conditions affect its flow. This is important for predicting the future...

Iceberg Breaks Off Pine Island Glacier, May Disrupt Shipping Lanes
2013-11-14 15:21:30

Lee Rannals for redOrbit.com - Your Universe Online Researchers from the University of Sheffield and Southampton were awarded an emergency grant to study how an iceberg that recently separated from an Antarctic glacier could disrupt shipping lanes. Scientists were given $80,000 to fund a six-month study that will predict the movements of a 270-square-mile iceberg that began drifting away from Pine Island Glacier in Antarctica back in July. A NASA image (above) taken by the Aqua...

Feast And Famine For Animals Living On The Abyssal Plain
2013-11-12 11:57:06

[ Watch The Video: Feast and Famine on the Abyssal Plain ] Monterey Bay Aquarium Research Institute Animals living on the abyssal plains, miles below the ocean surface, don’t usually get much to eat. Their main source of food is ”marine snow”—a slow drift of mucus, fecal pellets, and body parts—that sinks down from the surface waters. However, researchers have long been puzzled by the fact that, over the long term, the steady fall of marine snow cannot account for all the...

Amazon Deforestation Could Mean Droughts For Western United States
2013-11-07 12:22:13

Princeton University In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report that the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires. The researchers report in the Journal of Climate that an Amazon stripped bare could mean 20 percent less rain for the coastal...

Recent El Nino Patterns More Active Than In Past 600 Years
2013-10-29 07:31:26

April Flowers for redOrbit.com - Your Universe Online Scientists from the University of New South Wales, the University of Hawaii International Pacific Research Center and the NOAA Geophysical Fluid Dynamics Laboratory have developed a new approach to analyzing paleo-climate reconstructions of the El Niño Southern Oscillation (ENSO) phenomenon. Their findings, published in Climate of the Past, resolve disagreements and reveals that ENSO activity during the 20th century has been unusually...

Scientists have fingerprinted a distinctive atmospheric wave pattern high above the Northern Hemisphere that can foreshadow the emergence of summertime heat waves in the United States more than two weeks in advance. The new research, led by scientists at NCAR, could potentially enable forecasts of the likelihood of U.S. heat waves 15-20 days out, giving society more time to prepare for these often-deadly events. BOULDER, CO (PRWEB) October 28, 2013 Scientists have fingerprinted a...

GOCE Mission Data Used To Study Ocean Currnets
2013-10-28 12:57:20

[ Watch The Video: Ocean Currents In 1993 Through 2011 ] Lee Rannals for redOrbit.com - Your Universe Online Although the European Space Agency’s (ESA) Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite has completed its mission and is heading back to burn up in Earth’s atmosphere, it will be living on in spirit through another mission. The primary objective of the GOCE mission was to map Earth’s gravity with great precision. GOCE has been orbiting Earth...

Predicting Heat Waves
2013-10-28 10:37:52

Brett Smith for redOrbit.com - Your Universe Online New research published on Sunday in the journal Nature Geoscience could give meteorologists the ability to predict deadly summer heat waves more than two weeks ahead of time. In the study, scientists at the National Center for Atmospheric Research (NCAR) used a 12,000-year simulation of atmospheric patterns over the Northern Hemisphere to identify a distinctive "wavenumber-5" pattern that significantly increased the odds of a major...

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...
