Latest Physical oceanography Stories
A new study has found that turbulent mixing in the deep waters of the Southern Ocean, which has a profound effect on global ocean circulation and climate, varies with the strength of surface eddies – the ocean equivalent of storms in the atmosphere – and possibly also wind speeds.
Researchers compare bioerosion on deeper reef systems to better understand long-term structural sustainability
Algalita to host interactive broadcast and expert panel on July 20 from the North Pacific Ocean to discuss the latest research and issues regarding plastic pollution in our oceans.
New research shows projected changes in the winds circling the Antarctic may accelerate global sea level rise significantly more than previously estimated.
In a new study, an SDSU biologist dove deep into how algal and coral cover affect the microscopic life that call the reef home.
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 which match the five large open-ocean currents called gyres.
“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.
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.
Ice loss from the Greenland Ice Sheet has increased four-fold over the past four decades, and 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.
UC Santa Barbara doctoral candidate Caitlin Fong travels to French Polynesia often but not for vacation.
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...
