Leopard sharks are a special species of shark found only along the West coast of North America, their territory spanning from Washington to Baja California. A distinctive characteristic of these creatures is their mild temperament. Unlike most sharks, which will bite anything that might be food, leopard sharks are timid and have such small mouths that they pose essentially no danger to humans. In fact, a leopard shark bite on a human has never been recorded by the International Shark Attack File.
Every Summer La Jolla Shores is the gathering site of hundreds of leopard sharks. A common misconception of this behavior is that these sharks convene here to mate or give birth, but in fact scientists are not quite certain what they do at this annual conference.
Did you know there are unheard sounds in the Earth’s atmosphere that can travel all the way around the world?
Dr. Michael Hedlin of UC San Diego’s Scripps Institution of Oceanography explains that when massive events occur in the atmosphere low frequency sounds are generated that can be received all over the earth, depending on the magnitude of the event. Much like when there is an earthquake and seismic waves can be read on seismometers around the planet.
Although we cannot hear these sounds because of their low frequencies, there is still a lot they can tell us about things like volcanic eruptions and meteorite impacts.
When people want to learn about the ocean, they turn to Birch Aquarium at Scripps’ “Perspectives on Ocean Science” lecture series, available on TV and online through UCSD-TV and its sister station, UCTV.
How do we know? The collection of 130+ videos, available on the channels’ websites, YouTube and iTunes, just surpassed 10 million views, making it UCSD’s most popular science series and UCTV’s 14th most popular series, out of a whopping 350!
Climate warming due to increased carbon dioxide in the atmosphere is only part of the “CO2 problem” affecting life on the planet. In fact, much of the CO2 emitted from burning fossil fuels is absorbed by the ocean, causing ocean acidification, a chemical phenomenon threatening marine life.
Tune in to UCSD-TV tonight (Jan. 9) at 8 for “Ocean Acidification: Can Corals Cope?” from the Perspectives on Ocean Science series to hear Scripps marine biologist Martin Tresguerres describe research into the potential impact of ocean acidification on corals, and the mechanisms these amazing marine animals use to try to cope with the problem. Or just watch it online now!
We continue our presentations from The Atlantic Meets the Pacific forum held at UC San Diego in October. This month you’ll be joined by The Atlantic’s James Fallows, “The Happiness Project” author Gretchen Rubin, video game designer Jane McGonigal, Calit 2’s Larry Smarr and more, all talking about improving the world –and our lives– through innovation, entrepreneurship and technology. Tune in Mondays at 8pm or watch online.
E.W. Scripps Associates takes you on an exclusive adventure with Scripps Institution of Oceanography scientists and students who have explored the ocean depths and come away with amazing results. From discovery of the first-known methane seeps off San Diego to video and images from the deepest place on earth, we welcome you to take a sneak peek into the abyss.
This fascinating and important series from UC San Diego’s Center for Academic Research and Training in Anthropogeny (CARTA) explores the newest understandings of the roots of autism disorders from the foremost researchers in the world. Tune in Wednesday nights at 9 (through December 19) or watch online.
