GhostNet project - In 2001, ATI received a NASA grant to address the
issue of derelict fishing gear in the North Pacific using remote
sensing technologies. ATI put together a team consisting of government,
academia and industry. The team included NOAA NESDIS, NOAA National
Marine Fisheries Services and NOAA Environmental Technology Lab as well
as a group from the University of Southern California and the
University of Alaska Fairbanks. In brief, we are using ocean models
(e.g. Ocean Surface Current Simulations � OSCURS) to analyze the North
Pacific and find areas of expected convergence. Then, through the help
of NOAA NESDIS, satellite data is examined in the specified areas for
signs of actual convergence. Sustained convergence areas are tracked
daily and the information is used to direct an aerial search by
aircraft. Both ATI and NOAA ESRL worked together to design and build an
automatic anomaly detection system, which utilizes airborne remote
sensing equipment and ATI�s proprietary software to identify and record
anomalies in the ocean. High-resolution imagery is automatically taken
of each anomaly and available for immediate analysis by the system
operator on board the aircraft as well as personnel linked to the
aircraft via Internet connection. During March-April of 2005, we flew a
NOAA P3 aircraft into the Sub Tropical Convergence Zone north of
Hawaii. We successfully located and identified marine debris fields
including over 2000 individual debris items and nets.
