Latest Physical oceanography Stories
This weekend marks a century since the RMS Titanic struck an iceberg while crossing the North Atlantic, taking 1,500 lives down to the bottom of the sea with it.
Wednesday’s powerful 8.6-magnitude earthquake that struck off Indonesia’s western coast at 2:38 p.m. local time, was followed by fears of a tsunami, gripping a region that still had the 2004 tsunami -- one that ravaged numerous coastal communities along the Indian Ocean and killing more than 230,000 people -- fresh in their minds.
A tsunami warning has been issued for the entire Indian Ocean on Wednesday April 11 after a massive 8.7 magnitude earthquake off the coast of Indonesia at 2:38 p.m. local time (3:38 a.m. EST) sent residents around the region out of their homes and offices in fear.
El Nino is a term used to describe a weather pattern that sets up in the Tropical Pacific Ocean. So you may ask why does it matter to me and should it matter to me? The answer is yes because it impacts each and every one of us on Earth.
A new study has revealed a global warming and rising of the oceans. Contrasting ocean temperature readings from the 1870s with modern readings, this study reveals an upward rising trend spanning over 100 years.
A new study examining nearly 40 years of satellite imagery has revealed that the floating ice shelves of a critical portion of West Antarctica are steadily losing their grip on adjacent bay walls, potentially amplifying an already accelerating loss of ice to the sea.
Scientists have recently finalized an expedition in an effort to learn more about an undersea mountain they say may have formed in a very different way than the rest of the seafloor.
A large Japanese fishing trawler that was swept away by the devastating tsunami of 2011 has been spotted off the coast of British Columbia in the western part of Canada.
Sea level rise due to global warming has already doubled the annual risk of coastal flooding of historic proportions across widespread areas of the United States, according to a new report from Climate Central.
World leaders, scientists, and members of the media are among those pausing this weekend to reflect on the one-year anniversary of the 9.0 magnitude earthquake that struck Japan on March 11, 2011 and, combined with the ensuing tsunami, caused widespread death and destruction throughout the country.
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...
