When Tsunamis Break All The Rules
2013-03-07 05:04:34

[ Watch the Video: Animation of a Tsunami Wave ] April Flowers for redOrbit.com - Your Universe Online An international collaboration has resulted in a new study showing that the earthquake zones off certain coasts, such as Japan and Java, make them especially vulnerable to tsunamis. These zones can produce a focusing point that creates massive and devastating tsunamis capable of breaking the rules by which scientists used to think tsunamis worked. Previously, scientists largely...

Research reveals importance of location, location, location Fishers near marine protected areas end up traveling farther to catch fish but maintain their social and economic well-being, according to a study by fisheries scientists at Washington State University and in Hawaii. The study, reported in the journal Biological Conservation, is one of the first to look closely at how protected areas in small nearshore fisheries can affect where fishers operate on the ocean and, as a...

Salinity Levels In Atlantic Ocean Are Off The Chart, According To NASA Instrument
2013-02-28 12:35:28

WATCH VIDEOS: [Aquarius Measuring Salty Seas 1] - [Aquarius Measuring Salty Seas 2] Lawrence LeBlond for redOrbit.com - Your Universe Online The salinity level of the world´s rivers, lakes and oceans has been a growing topic in response to global climate change. As NASA´s Aquarius instrument has shown previously, seasonal salinity has been on the rise in oceans all around the world. This year, the picture is no less striking, with deep shades of oranges and reds, at least in...

Smartphone App Allows Seamen To Track Phytoplankton For Science
2013-02-24 08:08:54

redOrbit Staff & Wire Reports - Your Universe Online Researchers at the Plymouth University Marine Institute have developed a new smartphone app that they claim will allow regular folks to help scientists track the impact of climate change on phytoplankton. In a statement released Friday, the university reports that scientists are concerned that the tiny organisms, which are at the bottom end of the marine life food chain, could be decreasing in numbers due to increasing sea...

Deepest Hydrothermal Vent Discovered In Cayman Deep, Teeming With Life
2013-02-22 09:43:30

Lawrence LeBlond for redOrbit.com - Your Universe Online In 2010, scientists working for the National Oceanography Centre (NOC) and the University of Southampton made an astonishing discovery: the deepest and hottest known hydrothermal vents. These vents, which were found in an isolated trough in the Caribbean, have been named the Beebe Hydrothermal Vent Field (BHVF). With the discovery still fresh in their minds, a new team, led by the University of Southampton´s Dr. Jon Copley,...

Global Sea-Level Rise Could Occur Unevenly Across Globe
2013-02-19 15:43:16

Peter Suciu for redOrbit.com — Your Universe Online The fact sea levels could rise if the polar ice caps melt has been long established, but according to new research some regions could see greater increases than others. According to research published in the journal Geophysical Research Letters, sophisticated computer modeling of sea-level rise over the coming century suggests parts of the Pacific could see the highest rates of rise while some polar regions will actually...

Hurricane Sandy was a fearsome reminder that coastal communities are highly vulnerable to extreme weather events and environmental variability, and that vulnerability is only expected to increase with climate change. Brown University scientists Heather Leslie and Leila Sievanen, members of an interdisciplinary research team focused on human-environment interactions in coastal regions, will discuss these challenges this month at the annual meeting of the American Association for the...

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...
