PEOPLE IN L2A
| Dr Jon Berger |

Email: jberger@ucsd.edu
Phone:1 858 534-2889
With Dr Mark Zumberge is responsible for the development of a new distributed acoustic sensor. The sensor reduces noise due to air turbulence by averaging pressure along a line by means of fiber optic sensing of strain in a long tubular diaphragm. The Optical Fiber Infrasound Sensor (OFIS) is currently undergoing field tests. Dr Berger with Dr Michael Hedlin has designed several arrays in the new International Monitoring System (IMS) infrasound network and has built arrays in California and Washington State, USA. |

Email: ccoon@epicenter.ucsd.edu
Phone: 1 858 534-8773
Plays a key role in research at L2A by deploying and maintaining temporary experiment sites at the Infrasound Laboratory at Pinon Flat, California. Data from these experiments are telemetered in real-time
to our lab in La Jolla. Clint also serves as the chief engineer responsible for the smooth operation of the International Monitoring System infrasound arrays I56US at Newport, Washington State and I57US
at Pinon Flat, California. |

| Dr Catherine deGroot-Hedlin |
|---|
Email: chedlin@ucsd.edu
Phone:1 858 534-2313
Conducts research in atmospheric noise, array data processing and the modeling of acoustic wave propagation. |
| Dr Michael Hedlin |
|---|
Email: hedlin@ucsd.edu
Phone: 1 858 534-8773
Conducts research in the reduction of noise due to atmospheric turbulence. Dr Hedlin has studied noise reduction with mechanical spatial filters and wind barriers as well as the new fiber optic system
developed by Drs Berger and Zumberge. With Drs D'Spain, Rovner and Lewis Berger, Dr Hedlin studies the propagation of sound through our non-stationary atmosphere and the optimal design of infrasound arrays.
Dr Hedlin with Dr Jon Berger has designed arrays for the IMS and has constructed two IMS arrays in the USA. Dr Hedlin is the chair of L2A and is the primary point of contact for the lab. |

Phone: 1 858 534-0126
Kris is now looking at alternative ways to locate natural and
anthropogenic events that emit energy into the Earth. Potential sources
include earthquakes, land slides, volcanic eruptions, glacial movements,
meteorite impacts, and nuclear explosions. Kris Walker is also testing
the Optical Fiber Infrasound Sensor (OFIS), located at Piñon Flat
Observatory, to find the best method for calculating the backazimuth to a
specific event, and the optimum number and orientation of OFIS's in order
to make this calculation.
