U.S. NORTH PACIFIC GROUNDFISH
OBSERVER PROGRAM:
During the third quarter of 2003, 190 observers were trained, briefed,
and equipped for deployment to fishing and processing vessels and shoreside
plants in the Gulf of Alaska, Bering Sea, and Aleutian Islands region.
They sampled aboard 241 fishing and processing vessels and at 14 shoreside
processing plants for a total of 13,271 days. These observers were trained
or briefed in two locations. The Alaska Fisheries Science Center (AFSC)
Observer Program in Seattle briefed 34 observers with prior experience.
The University of Alaska Anchorage Observer Training Center (UAA/OTC) briefed
106 observers, and another 23 first-time observers were trained there.
Twenty-seven observers were excused from briefing because they had just
completed a cruise successfully and were returning immediately to the field.
The third quarter 2003 observer workforce comprised 12% new observers
and 88% experienced observers.
The Observer Program conducted a total of 149 debriefings during the third
quarter of 2003. Three debriefings were held in both Kodiak and Dutch
Harbor, 55 in Anchorage, and 88 were held in Seattle.
Safety Conference
Three Observer Program staff along with one UAA/OTC staff member gave several
presentations at the Second International Fishing Industry Safety and Health
Conference (IFISH II) in Sitka, Alaska, on 22-24 September 2003. The conference
was attended by about 130 people from more than 20 different countries.
The fishing industry is recognized as one of the most dangerous professions
in the United States. Yet in nearly 500,000 sea days logged by observers
from the North Pacific Groundfish Observer Program from 1986 to the present,
there has been only one observer death. This exemplary safety record is
due in large measure to the safety preparation afforded to observers in
training and annual briefings. The Observer Program and UAA/OTC staff
gave several presentations at IFISH II which highlighted various aspects
of the Observer Programs safety training including
-
An evaluation of the Observer Programs proactive safety training approach
using brainstorming sessions with observers and staff
-
An explanation of the development process for making safety training videos and their
use as an important supplement in the Observer Programs safety training curriculum
-
A description of the incorporation of a safety training module called, The Psychology of Survival
into the Observer Programs safety training, which helps to develop the all important
will to survive in observers.
Observer Sampling Manual and At-sea Data Messaging System
Significant changes are being made to both the observer sampling manual
and the observer at-sea data messaging system (ATLAS system) in preparation
for full implementation in 2004. The ATLAS system will be updated to
capture new data types, and changes will also be made to create better
efficiency and ease of use. The 500-page observer manual will receive
new formatting and graphics, new content, and will be easier to use.
The observer manual has been in existence since the mid-1970s and has
been used as a model for newly developed observer programs around the United
States and the world. It can be viewed on the AFSC web site at:
