Acoustic Investigations

Passive Acoustics Research Program Completes Fifth Year in 2012 Over the past five years the Laguna San Ignacio Ecosystem Science Project (LSIESP) has both directly and indirectly supported the collection of underwater acoustic data at the lagoon, performed by the Scripps Institution of Oceanography (SIO) and the Autonomous University of Southern Baja California (UABCS), continuing [...]

  The acoustics team of the LSIESP is comprised of scientists from the Scripps Institution of Oceanography of the University of California, San Diego (SIO/UCSD), in collaboration with researchers from the Universidad Autonoma de Baja California Sur (UABCS) and the Universidad Nacional Autonoma de Mexico (UNAM). Over the past four years the team has collected [...]

The Acoustics team performed two trips to San Ignacio Lagoon during the winter season of 2010: one initial visit to deploy bottom-mounted, long-term monitoring (LTM) instruments and a second, more extended expedition to tag individual whales. Scripps Ph.D. students Melania Guerra and Delphine Mathias arrived at the Lagoon campsite Kuyima Ecoturismo on February 5th and [...]

As in previous years, LSIESP’s 2009 agenda featured a project in gray whale acoustics. Data collection and analyses were performed by a team of scientists from Scripps Institution of Oceanography (SIO) in collaboration with researchers from the Universidad Autonoma de Baja California Sur (UABCS).

In 2008 we conducted our most ambitious San Ignacio Lagoon field season to date, consisting of one long term (four weeks) monitoring exercise using bottom recorders and one intense 10-day tracking effort with added acoustic arrays and bioacoustic tags on the animals.

Continuing the successful collaboration of the past two years, scientists from Scripps Institution of Oceanography (SIO) at the University of California San Diego (UCSD) participated in this year’s scientific field season at Laguna San Ignacio, Baja CaliforniaSur, Mexico. Complementing the work performed by our partners, the focus of our study remains the acoustics of gray whales and the propagation of these sounds in the lagoon waters.
