Swimming With Sharks

Published by: Brian Skerry - Oct 13, 2011

Lying in water only a foot deep, I watched the shark meander lazily through the mangrove, already exuding the confidence inherent of the supreme creature within its domain. It was hot here in Bimini, nearly 100-degrees and mosquitoes were thick and relentless, swarming on to any bare skin. Yet slipping my head just inches below the water’s surface I had entered another realm. I was absolutely transfixed watching these little sharks, perhaps 12 to 18 inches long; swimming beneath mangrove roots and over the muddy bottom with impressive deftness.

Teaching Your Students About Marine Debris: a Classroom Activity

Published by: Catherine - Sep 15, 2011

Have you ever gone to your favorite coastal or lakeside beach and instead of having a fun day in the sun you were faced with a trove of trash? How heartbreaking it is to see waters and shorelines littered with items that you have at home, that maybe you’ve even recently thrown away.

New Archaeocetes from Peru Are the Oldest Fossil Whales from South America

Published by: Nicholas D. Pyenson - Sep 12, 2011

The evolution of whales represents one of the great stories in macroevolution. It's a narrative that has mostly benefitted from an extraordinary series of fossils recovered from rocks around the world, including challenging field areas in Egypt, Pakistan, and India.

Arctic Sea Ice: A New Low?

Published by: Tina Tennessen - Sep 8, 2011

At a recent staff meeting a Smithsonian colleague mentioned that one of his pastimes this summer has been keeping tabs on the Arctic sea ice. The question that's on many Arctic-watchers' minds is whether or not the 2011 sea ice coverage will reach a new record low.

This graph of the Arctic sea ice coverage shows how close the year 2011 is to reaching a record-low. The graph contains data through September 7, 2011. The National Snow and Ice Data Center, which produced the graph, says we should know within a couple weeks if the ice extent drops below the previous record which was set in 2007.

Alaska Vulnerable to Invasive Species from Warmer Waters

Published by: John Barrat - Sep 1, 2011

Alaska’s pristine coastline is ripe for an influx of invasive marine species such as the European green crab and the rough periwinkle (an Atlantic sea snail), warns a new study by a team of scientists from the Smithsonian Environmental Research Center.

A Guide to Earthquake Lesson Plans

Published by: Maggy Hunter Benson - Aug 25, 2011

It isn’t everyday that a magnitude 5.8 earthquake strikes the East Coast of the United States. But on August 23, 2011, people from Georgia to New England felt the rumble and shaking of an earthquake whose epicenter was in Mineral, Va. The East Coast is historically a low risk zone. What exactly happened and how might educators use this event in the classroom?

Scientists Call New Eel Species A Living Fossil

Published by: Johnny Gibbons - Aug 17, 2011

Scientists at the Smithsonian and partnering organizations have discovered a remarkably primitive eel in a fringing reef off the coast of the Republic of Palau. This fish exhibits many primitive anatomical features unknown in the other 19 families and more than 800 species of living eels, resulting in its classification as a new species belonging to a new genus and family.

The Palauan primitive cave eel (Protanguilla palau) has an evolutionary history that dates back some 200 million years. Smithsonian ichthyologist David Johnson and colleagues described the new genus and species for the first time on August, 17, 2011 in the Proceedings of the Royal Society B.

On Biodiversity: Understanding its Meaning and Importance

Published by: Cristina Castillo - Aug 16, 2011

The ocean is home to a phenomenal diversity of marine organisms. They have evolved to inhabit warm waters near the equator and the icy waters of the Earth’s poles. Marine life takes advantage of the enormous volume the ocean comprises: from diatoms living near the sunny surface, to octopods living in the dark deep sea.

These mollusks and echinoderms are a teeny-tiny sample of the ocean's biodiversity. The Census of Marine Life estimates that there are at least one million species of plants and animals in the sea. Most of which have not been described. The nine animals in this photo were collected by Smithsonian researchers involved in the Deep Reef Observation Project

An Intern Explores Ocean Careers

Published by: Brandon Adkins - Aug 4, 2011

I’m a high school student interested in pursuing marine science. I have loved the ocean since I was 3 feet tall and only getting my feet wet at the beach. I’m a senior in high school, and over the next year I have the task of selecting a college, but I’m also thinking about my major and future profession. I know how hard it can be trying to figure out what career you would like to pursue especially with sports, school clubs, and television influencing your decision.
