Title:
Deep-Crustal Seismic data of field activity G-1-95-SF in San Francisco Bay from 04/17/1995 to 04/28/1995
Abstract:
Chief Scientists: Jill McCarthy, Pat Hart. Deep-Crustal Seismic data (seismic) of field activity G-1-95-SF in San Francisco Bay from 04/17/1995 to 04/28/1995, <http://walrus.wr.usgs.gov/infobank/g/g195sf/html/g-1-95-sf.meta.html>.

Notes -
"BAY CABLE" CRUISE NEWS: The bay cable flotilla has been
successfully working through problems asthey arise (or drift away).
Mike, Jon, Pat, and Co. are seeing great first break arrivals on the
recorders that seem to be stronger than BASIX 1991. They believe
this means the very deep reflections will be that much more
resolvable. Working with the variable winds and rough chop have
presented difficulties, but nothing unexpected as of yet. The
streamer was deployed on Wed.; shooting began on Thurs.; and
retrieval begins today. Jill reports that the radio trigger is
experiencing interference as they approach the San Francisco
waterfront causing some missed shots. Curious sailboats are
understandably keeping their distance. Kevin's MARFAC team and
Curtis' Gray team are doing an outstanding job keeping everything
"safe and sane".- Ray Sliter
