New Sea Level Threat Created From Changing Antarctic Winds
2014-07-07 03:55:30

Australian Research Council's Centre of Excellence for Climate System Science New research shows projected changes in the winds circling the Antarctic may accelerate global sea level rise significantly more than previously estimated. Changes to Antarctic winds have already been linked to southern Australia’s drying climate but now it appears they may also have a profound impact on warming ocean temperatures under the ice shelves along the coastline of West and East Antarctic....

How Does Algal And Coral Cover Affect Microscopic Life That Call The Reef Home?
2014-07-07 03:56:00

By Michael Price, San Diego State University A new study by biologists at San Diego State University and Scripps Institution of Oceanography shows that inhabited coral islands that engage in commercial fishing dramatically alter their nearby reef ecosystems, disturbing the microbes, corals, algae and fish that call the reef home. The study’s lead author, Linda Wegley Kelly, is a postdoctoral scholar in the lab of SDSU virologist Forest Rohwer. She's been involved in some capacity...

Malaspina Expedition Finds World's Oceans Littered With Microplastics
2014-07-01 11:18:07

Brett Smith for redOrbit.com - Your Universe Online The result of a 2010 ocean voyage around the world, a new study has found evidence of tiny “microplastics” in five large accumulations across the world -- accumulations that match the five large open-ocean currents called gyres. According to the study, which was published in the Proceedings of the National Academy of Sciences, large amounts of these microplastics could be moving through the marine food chain or sinking to the ocean...

tsunami earthquakes
2014-06-28 05:08:15

redOrbit Staff & Wire Reports - Your Universe Online “Sticking points” in the Earth’s tectonic plates caused by extinct undersea volcanoes could be responsible for producing tsunami earthquakes, a discovery which could lead to improved detection of these rare seismic events. Tsunami earthquakes typically occur at relatively shallow ocean depths and are typically of lower magnitude. However, they can create extremely large tsunamis, with earthquakes measuring as little as 5.6...

Greenland Ice Sheet Collapse Linked To Sea Level Rise 400,000 Years Ago: Study
2014-06-26 03:26:40

Oregon State University A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some 4-6 meters. The study is one of the first to zero in on how the vast Greenland ice sheet responded to warmer temperatures during that period, which were caused by changes in the Earth's orbit around the sun. Results of the study,...

Analyzing The Role Of The Ocean In Greenland Ice Sheet Melting
2014-06-24 06:51:19

redOrbit Staff & Wire Reports - Your Universe Online Ice loss from the Greenland Ice Sheet has increased four-fold over the past four decades, and while warmer atmospheric conditions are to blame for increased melting at the glacier’s surface, scientists now report that oceans play a vital role in how quickly the ice sheet will melt and how much total mass will be lost. According to researchers from the Woods Hole Oceanographic Institution (WHOI) and the University of Oregon,...

The UC Santa Barbara Current A graduate student assesses the underlying assumptions and predictive ability of functional-group models used to study seabed communities UC Santa Barbara doctoral candidate Caitlin Fong travels to French Polynesia often but not for vacation. She goes there to study a coral reef ecosystem influenced by human impacts such as overfishing and nutrient pollution. Her work focuses not only on biological changes but also methods scientists use to determine...

Juvenile Corals Fed Prior To Transplantation To New Reef More Successful
2014-06-06 14:57:37

PLOS Feeding juvenile corals prior to transplantation into a new reef may increase their survival, according to a study published June 4, 2014 in the open-access journal PLOS ONE by Tai Chong Toh from the National University of Singapore and colleagues. The global decline of coral reefs and the loss of associated ecological services have necessitated immediate intervention measures to try to reverse their further deterioration. Scientists have attempted to recolonize damaged reefs by...

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

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...
