Earthquake In British Columbia Leads To Tsunami Warnings
2012-10-28 07:07:05

redOrbit Staff & Wire Reports - Your Universe Online A magnitude 7.7 earthquake struck the Canadian province of British Columbia late Saturday night, leading to short-lived tsunami warnings and mass evacuations as far away as Hawaii, according to various media reports. The earthquake was centered in the Queen Charlotte Islands area (also known as Haida Gwaii) of British Columbia, US Geological Survey (USGS) officials told Mark Thiessen and Oskar Garcia of the Associated Press (AP),...

Ocean Acoustics Changing
2012-10-19 14:07:43

Brett Smith for redOrbit.com - Your Universe Online Along with negatively impacting marine life and global climate change, the acidification of the Earth´s oceans could have the unintended side effect of changing the acoustics beneath the water´s surface. New research suggests that a future, more acidic ocean would resemble the one that existed around 110 million years ago, when dinosaurs still roamed both the land and sea. Climatologists have been raising concerns in recent...

Gulf Stream Shift Has Warmed New England Waters
2012-10-13 10:00:29

redOrbit Staff & Wire Reports - Your Universe Online The ocean waters around the New England continental shelf were warmer than usual thanks to a divergence in the Gulf Stream path that started about one year ago, researchers from the Woods Hole Oceanographic Institution (WHOI) announced on Thursday. The study, which was published in the August edition of the journal Scientific Reports, began after local commercial fisherman met with WHOI members and alerted them to unusually high...

Fish Poop May Be Critical To Ocean Carbon Cycle
2012-10-11 12:28:11

Alan McStravick for redOrbit.com - Your Universe Online Professor Deborah Steinberg of the Virginia Institute of Marine Science (VIMS) has dedicated her professional life to investigating crustaceans and their role in the “biological pump,” which is the process by which marine life transports carbon dioxide from the atmosphere and ocean´s surface to the deep sea. This cycle removes the carbon to a depth where it contributes nothing to global warming. In a new study...

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

Brett Smith for redOrbit.com - Your Universe Online 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. The study, published in the latest edition of the journal Environmental Research Letters, expanded the scope of typical climate change studies to include thousands of years in its projections and also took into consideration all of the Earth´s land ice,...

Scientists at the University of Rhode Island's Graduate School of Oceanography have made the first observation of a predator avoidance behavior by a species of phytoplankton, a microscopic marine plant. Susanne Menden-Deuer, associate professor of oceanography, and doctoral student Elizabeth Harvey made the unexpected observation while studying the interactions between phytoplankton and zooplankton. Their discovery will be published in the September 28 issue of the journal PLOS ONE. "It...

A Better Look At Salinity From SMOS
2012-10-01 08:26:12

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. Since its launch in 2009, ESA´s Soil Moisture and Ocean Salinity (SMOS) satellite has been helping us to understand the water cycle. As with any Earth observation mission, it is important to validate the readings acquired from space. This involves comparing the satellite data with...

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
2012-11-17 08:24:58

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...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
