Latest Physical oceanography Stories
By using electromagnetic technology to map a large area of seafloor near Central America and the northern East Pacific Rise, researchers from the Scripps Institution of Oceanography report that they have a better idea of the origin of the erupted magma that eventually becomes new seafloor.
The oft-cliché idea behind the naming of Iceland and Greenland claims their names were derived in an attempt to fool would be sailing marauders, attracting them to the desolate but more hospitably named Greenland, leaving the citizens of Iceland to live upon their slightly more lush island without threat of invasion.
All living organisms rely on iron as an essential nutrient. In the ocean, iron’s abundance or scarcity means all the difference as it fuels the growth of plankton, the base of the ocean’s food web.
An international collaboration has resulted in a new study showing that the earthquake zones off certain coasts, such as Japan and Java, make them especially vulnerable to tsunamis.
In recent years, the world has suffered from severe regional weather extremes such as the heat wave in the US in 2011, or the one in Russia in 2010 that coincided with the unprecedented Pakistan flood.
The fact sea levels could rise if the polar ice caps melt has been long established, but according to new research some regions could see greater increases than others.
A recent study conducted in the Fiji Islands found that four species of herbivorous fish were primarily responsible for removing common and even potentially harmful seaweeds on reefs.
After noticing a strange plume of shimmering water, scientists have discovered a rare cold-water volcanic vent in the Southern Ocean.
Villages on the Solomon Islands were struck by an 8.0 magnitude earthquake Wednesday, triggering a deadly tsunami. Coastal Pacific communities as far away as Hawaii and Australia were also on high alert following the temblor.
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...
