Latest Physical oceanography Stories
A new study claims earthquakes and volcanoes are responsible for the diverse nature of the ocean’s coral reefs. With this information, scientists are now becoming even more worried about global warming.
Researchers have shown that, by using global positioning systems (GPS) to measure ground deformation caused by a large underwater earthquake, they can provide accurate warning of the resulting tsunami in just a few minutes after the earthquake onset.
A new study reveals that the world's collection of small glaciers are contributing just as much to global sea rise as the two massive ice sheets of Greenland and Antarctica.
Researchers writing in the Royal Meteorological Society publication Weather said forecasting winter weather over Europe has become more difficult over the years.
The mechanism underlying three unique reef formations and how they developed over evolutionary time has produced an enduring debate between two hypotheses – the first from English naturalist Charles Darwin and the second from geologist Reginald Daly. A new study has put an end to both conflicting theories.
A new study presents a sophisticated computer model that provides fresh insight into the impact of climate change on the production of icebergs by Greenland glaciers. The model also demonstrates the shape of the ground beneath the ice has a strong effect on its movement.
As a changing climate threatens to bleach the corals of the world’s oceans on a massive scale, a team of researchers has discovered why some corals respond differently to bleaching than others.
For much of Asia, the pace of life is tuned to rhythms of monsoons.
In 2009, the North Carolina Coastal Resources Commission (CRC), a body that controls and regulates coastal development in North Carolina, asked 13 members of its advisory Science Panel to prepare a report on the state of sea-level rise in North Carolina.
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...
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...
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...
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...
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...
