The tropical Pacific Ocean has transitioned from last winter's El Niño conditions to a cool La Niña, as shown by new data about sea surface heights, collected by the U.S-French Ocean Surface Topography Mission (OSTM)/Jason-2 oceanography satellite. This OSTM/Jason-2 image of the Pacific Ocean is based on the average of 10 days of data centered on Sept. 3, 2010. A new image depicts places where the Pacific sea surface height is higher (warmer) than...

New detailed observations of what happens when glaciers float on ocean surface Glaciers that lose their footing on the seafloor and begin floating behave very erratically, according to a new study led by a Scripps Institution of Oceanography, UC San Diego researcher. Floating glaciers produce larger icebergs than their grounded cousins and do so at unpredictable intervals, according to Scripps glaciologist Fabian Walter and colleagues in a paper to be published in the journal Geophysical...

Greenhouse gases are playing a role in changes, say scientists Newly detected rising sea levels in parts of the Indian Ocean, including the coastlines of the Bay of Bengal, the Arabian Sea, Sri Lanka, Sumatra and Java, appear to be at least partly a result of human-induced increases of atmospheric greenhouse gases, says a study led by the University of Colorado at Boulder. The study, which combined sea surface measurements going back to the 1960s and satellite observations, indicates...

The latest image of Pacific Ocean sea surface heights from the NASA/European Ocean Surface Topography Mission/Jason-2 oceanography satellite, dated June 11, 2010, shows that the tropical Pacific has switched from warm (red) to cold (blue) during the last few months. The blue area in the center of the image depicts the recent appearance of cold water hugging the equator, which the satellite measures as a region of lower-than-normal sea level. Remnants of the El Niño warm...

A robotic yellow submarine that has been launched deep beneath the Pine Island Glacier has helped to solve a mystery about one of Antarctica's fastest-melting glaciers, adding to unease about how climate change may lead to higher world sea levels, scientists reported on Sunday in the journal Nature Geoscience. Scientists captured ocean and sea-floor measurements using the robotic submarine, called Autosub. The team found that the glacier was no longer resting on a sub-sea ridge that had...

Sea level has not been as high as the distinctive ridges that run down the length of Florida for millions of years. Yet recently deposited marine fossils abound in the ridges' sands. Now, a University of Florida geologist may have helped crack that mystery. In a paper appearing June 1 in the June edition of the journal Geology, Peter Adams, a UF assistant professor of geological sciences, says his computer models of Florida's changing land mass support this theory: The land that forms the...

LOS ANGELES, May 28 /PRNewswire/ -- Adventurer, filmmaker, and environmentalist, Sebastian Copeland has embarked on a 1,367 mile trip across Greenland via kite-ski to help raise awareness about the effects of global warming on Greenland's climate. It is a sense of urgency which drives Copeland to cross Greenland's melting ice cap and document his exciting, yet, sobering journey over the next 40 to 50 days as he travels the majestic landscape from south to north. "Greenland's melting ice...

Scientists from the University of Miami are surprised at how rapidly the ice is melting in Greenland and how quickly the land is rising in response. Their findings are published in Nature Geoscience. Greenland is situated in the Atlantic Ocean to the northeast of Canada. It has stunning fjords on its rocky coast formed by moving glaciers, and a dense icecap up to 2 km thick that covers much of the island--pressing down the land beneath and lowering its elevation. Now, scientists at the...

When a temple was raised for Matsu -- the goddess of the sea -- in south Taiwan 300 years ago, worshippers felt the spot chosen would be a safe retreat from the ocean. They never took global warming into consideration. Now, as sea levels are rising, the township of Tungshih is forced to erect a new temple nearby, up 10 feet from the original site. Tsai Chu-wu, chief secretary of the temple, told the AFP news agency that the temple floods almost every year now, which explains why the...

Scientists have discovered that changes in the amount of ice floating in the polar oceans are causing sea levels to rise. The research, published this week in Geophysical Research Letters, is the first assessment of how quickly floating ice is being lost today. According to Archimedes' principle, any floating object displaces its own weight of fluid. For example, an ice cube in a glass of water does not cause the glass to overflow as it melts. But because sea water is warmer and more salty...

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...

A radar altimeter measures altitude above the terrain beneath an aircraft as opposed to a barometric altimeter which provides the distance above a pre-determined datum, usually sea level. Radar is the underpinning principle of the system. Radio waves that are reflected back from the ground are timed in order to calculate speed, distance, and time which are related to the each other and can be used to calculate the distance from one point to another. Lloyd Espenschied invented the radar...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
