Indonesian Earthquake: Update
2012-04-11 08:37:20

Lawrence LeBlond for RedOrbit.com Wednesday´s powerful 8.6-magnitude earthquake that struck off Indonesia´s western coast at 2:38 p.m. local time, was followed by fears of a tsunami, gripping a region that still had the 2004 tsunami -- one that ravaged numerous coastal communities along the Indian Ocean and killing more than 230,000 people -- fresh in their minds. But hours after the fears of a tsunami subsided, a strong 8.2-magnitude aftershock hit the region sparking a new...

8.7 Earthquake Prompts Tsunami Warnings For Indian Ocean Coastlines
2012-04-11 05:33:00

Lawrence LeBlond for RedOrbit.com A tsunami warning has been issued for the entire Indian Ocean on Wednesday April 11 after a massive 8.7 magnitude earthquake off the coast of Indonesia at 2:38 p.m. local time (3:38 a.m. EST) sent residents around the region out of their homes and offices in fear. The US Geological Survey (USGS) said the temblor was centered 20 miles beneath the ocean floor, a little more than 300 miles from the provincial capital of Banda Aceh. The quake put emergency...

Ice Sheet Collapse And Sea-level Rise At The Bølling Warming 14,600 Years Ago
2012-04-06 04:23:00

International scientists have shown that a dramatic sea-level rise occurred at the onset of the first warm period of the last deglaciation, known as the Bølling warming, approximately 14,600 years ago. This event, referred to as Melt-Water Pulse 1A (MWP-1A), corresponds to a rapid collapse of massive ice sheets 14,600 years ago and resulted in global sea-level rise of ~14 m. These findings are published in the 29 March 2012 issue of the journal Nature (Volume 483, Issue 7391)....

Image 1 - Crust Below Mississippi Delta Still Subsiding, Just Much Slower
2012-04-04 04:21:55

New data suggests that the Mississippi Delta is still sinking, but at a much slower rate than previously estimated. A new paper published in the journal Earth and Planetary Science Letters reports these new findings. Geoscientists arrived at this new conclusion after comparing detailed sea-level reconstructions from different areas of coastal Louisiana. The new findings not only reveal new information about the subsidence of the Mississippi Delta, but also admonishes the continuous...

Are Ocean Levels And Temperatures On The Rise?
2012-04-02 13:29:53

A new study has revealed a global warming and rising of the oceans. Contrasting ocean temperature readings from the 1870s with modern readings, this study reveals an upward rising trend spanning over 100 years. Dan Roemmich, a Scripps Institution of Oceanography at UC San Diego physical oceanographer led the research. He found a .33 degree Celsius (.59-degree Fahrenheit) increase on average in the top portions of the ocean, down to 700 meters. Ocean surface temperatures, however, saw the...

Ecologists in New Zealand have shown for the first time that Marine Protected Areas — long advocated as a way of protecting threatened marine mammals — actually work. Their study, based on 21 years' monitoring and published today in the British Ecological Society's Journal of Applied Ecology, reveals that a marine sanctuary off the coast of Christchurch has significantly improved survival of Hector's dolphins — one of the rarest dolphins in the world. Covering 1170 km2 of...

Life deep in the seabed proceeds very slowly. But the slow-growing bacteria living many meters beneath the seafloor play an important role in the global storage of organic carbon and have a long-term effect on climate. A team of scientists from Aarhus University (Denmark) and the University of Rhode Island have developed a new method for measuring this slow life deep down in the seabed. According to URI Oceanography Professor Arthur Spivack, the relative abundance of amino acids that are...

Image 1 - Weather Education Episode #3 - How Latitude Can Create Misleading Weather Forecasts
2012-03-27 06:06:05

RedOrbit Meteorologist Joshua Kelly In the past two chapters we saw how water topography impact the weather. For today's lesson we are going to look at how latittude also plays an important role in weather forecasting. Let´s take a look at Seattle, Washington, which happens to be our farthest north example here. Seattle is north so it should be the coldest of all our spots based on its latittude right? No. In this case Seattle´s latitude has little impact on its weather....

RoadFish.com men´s lifestyle and finance magazine congratulates James Cameron on his solo dive to the deepest depths of the ocean, the first time in history such a feat has been accomplished New York, NY (PRWEB) March 26, 2012 RoadFish.com men´s lifestyle and finance magazine today praised Hollywood director James Cameron for his latest undertaking: not a top-grossing film, but a solo dive into the 7-mile deep Mariana Trench. Cameron is only the third human being ever to reach...

Into The Deep: James Cameron Goes All The Way
2012-03-26 12:39:35

Lawrence LeBlond for RedOrbit.com Famed “Titanic” director James Cameron made history on March 25, 2012 when he became the first person to make a solo dive to the deepest point on Earth aboard the Deepsea Challenger submersible. The “vertical torpedo” dive, which took Cameron to the bottom of the Mariana Trench (35,756 feet down) in the Pacific Ocean, took roughly 2 hours and 36 minutes, where he was all alone in a deep, dark, cold alien world, much like Ed...

Baffin Bay
2013-04-18 13:21:50

Baffin Bay, which is located between Baffin Island and the southwest coast of Greenland, is a marginal sea of the North Atlantic Ocean. It’s connected to the Atlantic by Davis Strait and the Labrador Sea. A narrower Nares Strait connects the Baffin Bay with the Arctic Ocean. The Baffin Bay is an arm of the Atlantic Ocean that is bordered by Baffin Island towards the west, Greenland towards the east, and Ellesmere Island towards the north. It is connected to the Atlantic through the Davis...

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...

Ocean Acidification
2013-04-01 10:32:20

Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...

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...

Ocean Analysis for November 17, 2012

Point #1: Warm finger- This region inside the area marked number 1, represents a warm finger of the ocean temperatures. What is occurring is that the warmer air is being pushed faster in this region than the surrounding locations giving us this little finger of warmer temps in that region. Point #2: Warm Eddie- This is a region of warmer temps surrounded on all sides by colder water. Eddies are a closed circulation of water in the ocean that has in this case warmer temps around it. These...
