The War on Lionfish as an Invasive Species|
February 16, 2014 | Oregon State University

“This visualization shows ocean surface currents around the world during the period from June 2005 through Decemeber 2007. The visualization does not include a narration or annotations; the goal was to use ocean flow data to create a simple, visceral experience.” Quoted from the NASA YouTube Channel.

December 17, 2013 | National Oceanography Centre
“The risk posed by tsunami waves generated by Canary Island landslides may need to be re-evaluated, according to researchers at the National Oceanography Centre. Their findings suggest that these landslides result in smaller tsunami waves than previously thought by some authors, because of the processes involved.” Quoted from a National Oceanography Centre press release.

Partial Solar Eclipse Visible on Sunday Morning from the East Coast|
November 1, 2013 | NASA
“The final event of 2013 is the most interesting eclipse of the year. It is one of the rare hybrid or annular/total eclipses in which some sections of the path are annular while other parts are total. The duality comes about when the vertex of the Moon’s umbral shadow pierces Earth’s surface at some locations, but falls short of the planet along other sections of the path.” Quoted from the NASA website.
People as far west as Pittsburgh should be able to see the eclipse. Observing from the east coast.
EYE SAFETY during a solar eclipse.
Why Does it Rain More in the Northern Hemisphere?|
October 30, 2013 | University of Washington
“It rains more in the Northern Hemisphere because it’s warmer,” said corresponding author Dargan Frierson, a UW associate professor of atmospheric sciences. “The question is: What makes the Northern Hemisphere warmer? And we’ve found that it’s the ocean circulation.” Quoted from the University of Washington press release.

“With 5,800 miles of coastline surrounded by warm tropical and subtropical waters, Mexico is no stranger to tropical storms. But on September 15-16, 2013, the country experienced a rare double strike as two storms moved ashore simultaneously, one from the Pacific and one from the Atlantic.” Quoted from the Earth Observatory image release.

Micronutrient Plumes from Hydrothermal Vents|
September 16, 2013 | Woods Hole Oceanographic Institution
“Scientists have discovered a vast plume of iron and other micronutrients more than 1,000 km long billowing from hydrothermal vents in the South Atlantic Ocean. The finding [...] calls past estimates of iron abundances into question, and may challenge researchers’ assumptions about iron sources in the world’s seas.” Quoted from the Woods Hole Oceanographic Institution press release.

Tsunami on the Delaware River?|
September 4, 2013 | United States Geological Survey
“Imagine the Delaware River abruptly rising toward Philadelphia in a tsunami-like wave of water. Scientists now propose that this might not be a hypothetical scenario. A newly published paper concludes that a modest (one-foot) tsunami-like event on the East Coast was generated in the past by a large offshore earthquake. This result may have potential ramifications for emergency management professionals, government officials, businesses and the general public.” Quoted from the USGS Newsroom.

Impact of Eyjafjallajokull On Ocean Biology|
May 17, 2013 | University of Southampton
Research at the University of Southampton determined that the 2010 eruption of Eyjafjallajökull supplied dissolved iron to a large area of the North Atlantic. This stimulated photoplankton growth but the abundance of iron caused the rapid removal of biological nitrate which applied a throttle on the phytoplankton.
