Latest Physical oceanography Stories
A higher-than-normal 2010 melting season sped up the melting of ice in southern Greenland, causing sizable portions of the island's bedrock to rise somewhere about a quarter of an inch more than usual.
The deadly tsunami generated from the March 2011 Tohoku-Oki earthquake that devastated northeastern Japan resulted from merging waves, causing the killer tsunami to double in intensity over ocean ridges, and then amplifying its power upon landfall.
A new study, led by PRBO Conservation Science (PRBO), projects a bleak future for San Francisco Bay's tidal marshes under high-end sea-level rise scenarios that are increasingly likely.
The new study can aid scientists in better understanding regional and global effects of climate change in the Pacific.
Scientists set out on an expedition to explore the depths of the Indian Ocean on Monday from Cape Town, exploring areas where the deepest sea creatures lie.
After discovering an emerging crack that cuts across a floating ice shelf, NASA's Operation IceBridge has flown a follow-up mission and made the first-ever detailed airborne measurements of a major iceberg calving in progress.
An estimated 5 million to 20 million tons of debris now floating in the ocean following Japan's massive tsunami is due to hit the shores Hawaii by early next year, before reaching the U.S. West coast sometime in 2014.
Earth warming will presumably not lead to a permanent El Niño state in the South Pacific Ocean.
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...

- A sleeping-potion; a soporific.
- To mutter deliriously.
