Berardo appeared to be cruising, as the junior opened the bottom of the second with two quick outs, but Cornell racked up two singles and a walk before second baseman Matt Langseth plated the game’s first run with a single. Berardo then walked in a second run to stake the Crimson to a 2-0 deficit. With Big Red starter Tony Bertucci pitching lights-out, Harvard would never have a chance to climb back...
...scientists onboard the Langseth and other seismic vessels say they do take the impact on animals into account. American vessels are required by U.S. law to submit their itineraries to the National Marine Fisheries Service (NMFS), which in turn determines how long and where the vessels can operate. Several individuals and organizations raised concerns about the proposed study, including potential interruptions to breeding times and migration routes. NMFS then revised the authorized track lines in light of the comments. "We typically start six to 12 months before a cruise with discussions with [L-DEO] about our cruise plan...
During its survey, the Langseth had five approved observers on board to watch for marine mammals for 30 minutes before any airgun use. The operation shut down if any were spotted. They used passive acoustic monitoring (PAM) to detect vocalizing marine mammals in times of poor visual clarity. But Rose says that animals are often silent, and some "have high frequency vocalizations, which can only be detected when a PAM system is quite close." In other words, it would be too late to avoid airgun harm. Lee-Ann Ford, president and founder of Hong Kong-based Linking Individuals for Nature...
...debate moved into the waters off Taiwan this spring when experts went out to collect data to better understand why the Chichi quake happened. The Marcus G. Langseth, owned by the U.S. National Science Foundation (NSF) and operated by the Columbia University's Lamont-Doherty Earth Observatory (L-DEO), scouted underground formations for almost four months around Taiwan this spring, during which the crew popped its 36 airguns in the water every 20 or 60 seconds, depending on the instruments used to record the acoustic waves. Airguns, which are towed underwater at the back of the ship, cause loud, explosive...
...regional network of marine-mammal experts says the Langseth may have done more harm than good during its nearly four-month tour. The area where the ship was sailing is home to about 34 cetacean species, of which seven are fragile marine-mammal species, like the critically endangered Indo-Pacific humpback dolphin that lives along a 60-mile (100 km) stretch of Taiwan's west coast. "Seismic airguns are very loud, and under certain circumstances they can cause actual physical damage," says Rose. "When a species such as the humpback dolphin is already facing many threats and is hovering...
