A new survey of barrier islands published earlier this spring offers the most thorough assessment to date of the thousands of small islands that hug the coasts of the world's landmasses. The study, led by Matthew Stutz of Meredith College, Raleigh, N.C., and Orrin Pilkey of Duke University, Durham, N.C., offers new insight into how the islands form and evolve over time "“ and how they may fare as the climate changes and sea level rises. The survey is based on a global collection of...

Forecasting the state of the sea is important for shipping, offshore and coastal engineering, management of coastal zones and tourism. This is set to become easier through ESA's GlobWave project, which offers a one-stop shop for satellite data on ocean waves. Safety and financial losses associated with rough seas are a real concern. Ocean waves slow down the passage of ships, endanger marine industries such as oil and gas extraction, damage aquaculture and offshore wind farms, and erode...

Venice "“ the City of Dreams "“ may have one less nightmare to deal with following a finding that the frequency of extreme storm surge events generated by Adriatic Sea tempests could fall by about 30 percent by 2100. A team of international scientists led by CSIRO's Dr Alberto Troccoli studied atmospheric circulation in the Mediterranean region to assess climate impacts through changes in storm surge frequency in Venice "“ a World Heritage-listed city built on 117 small...

An unusual signal detected by the seismic monitoring station at the Smithsonian Tropical Research Institute's research facility on Barro Colorado Island results from waves in Lake Gatun, the reservoir that forms the Panama Canal channel, scientists report. Understanding seismic background signals leads to improved earthquake and tsunami detection in the Caribbean region where 100 tsunamis have been reported in the past 500 years.As part of a $37.5 million U.S. presidential initiative to...

Salt is essential to human life. Most people don't know, however, that salt -- in a form nearly the same as the simple table variety -- is just as essential to Earth's ocean, serving as a critical driver of key ocean processes. While ancient Greek soothsayers believed they could foretell the future by reading the patterns in sprinkled salt, today's scientists have learned that they can indeed harness this invaluable mineral to foresee the future -- of Earth's climate. The oracles of modern...

With an estimated 34,000 square miles of ice, an area about the size of Maine, Alaska's multitude of glaciers have a global impact. Anthony Arendt, an assistant research professor at the University of Alaska Fairbanks Geophysical Institute, has outlined the complexity and influence of Alaska glaciers in last week's issue of the journal Science. In his article, Arendt explains the importance of integrating field observations and more precise glacier simulation models. "We have used satellites...

Thirty-eight million years ago, tropical jungles thrived in what are now the cornfields of the American Midwest and furry marsupials wandered temperate forests in what is now the frozen Antarctic. The temperature differences of that era, known as the late Eocene, between the equator and Antarctica were half what they are today. A debate has been ongoing in the scientific community about what changes in our global climate system led to such a major shift from the more tropical, greenhouse...

Data from a radar network operated by a consortium of scientists along the U.S. West Coast are now a vital component in search-and-rescue, oil spill response and maritime transportation operations Scripps Institution of Oceanography / University of California, San Diego A network of high-frequency radar systems designed for mapping ocean surface currents now provides detail of coastal ocean dynamics along the U.S. West Coast never before available. The network has grown over the last decade...

The U.N. weather agency said on Monday that the La Nina weather pattern is easing and there are no signs that suggest a resurgence in the coming months. "The La Nina episode, which caused disastrously wet conditions in certain regions and drought in others, is coming to an end," the World Meteorological Organization (WMO) said in a statement to the AFP news agency. According to the WMO report, the weather pattern, which is being blamed for extremely heavy downpours in Australia, Southeast...

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
