Atlantic Heat Pump Was Once Faster
2012-10-16 13:39:01

A new study from an international team of scientists suggests that the circulation of the Atlantic Ocean – known as the Atlantic heat pump – was faster during the last Ice Age than today.

Scientists and flight crew members with Operation IceBridge, NASA's airborne mission to study Earth's changing polar ice, are beginning another campaign over Antarctica.

Sea Rise Will Be Irreversible Over Next Several Thousand Years Due To Greenhouse Gas Emissions
2012-10-02 15:25:24

A groundbreaking study by a team of European researchers warns that greenhouse gas emissions will cause an irreversible rise in sea level over the next several thousand years.

A Better Look At Salinity From SMOS

Earth observation measurements shouldn’t be taken with a pinch of salt. ESA is comparing readings of sea-surface salinity from drifting floats to confirm the SMOS water mission’s measurements.

'20 Years Of Progress In Radar Altimetry Symposium' Gains Altitude In Venice
2012-09-24 10:41:43

Scientists have gathered in the 'floating city' this week to talk about radar altimetry – measuring the heights of the global sea surface, freshwater bodies, land and ice using spaceborne sensors.

Antarctic Ice Facing Changes By Fast-Flowing Glaciers
2012-09-19 14:14:23

A new study found that fast-flowing and narrow glaciers could trigger massive changes in the Antarctic ice sheet, inevitably adding sea-level rise and ice-sheet decay.

Wave Interactions May Explain Why Some Tsunamis Are So Powerful
2012-09-19 08:31:09

Ocean waves are a source of calming for meditation, and a source of enjoyment for thrill-seeking surfers. But these waves are also a source of wonder for researchers trying to explain the power of the tsunami.

Global Temps Reach New Highs
2012-09-18 04:56:37

This has been a summer for setting climate/environmental records. The US has had a record-breaking fire season, with over 8 million acres ablaze. The Antarctic Sea Ice has melted to record-breaking low extent. And now this summer has become the third warmest on record.

Coral Reef
2013-04-20 15:49:21

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...

Current Sea Level Rise
2013-04-01 10:39:21

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...

Basic Ocean Terms
2013-02-05 12:52:11

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...

Climate Impact On Your Budget For Billings Montana
2012-12-29 12:40:14

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...

Climate Impact On Your Budget For Bismarck, North Dakota
2012-09-18 13:29:03

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...
