HEARING ON: DUAL USE OF DEFENSE TECHNOLOGY

QUESTIONS FOR THE RECORD TO DR. ERIC O. HARTWIG 



Question 3. Among the technologies that you talked about, are there ones which 

 would be applicable for remotely assessing fisheries? Could any of them be used 

 for marine mammals and endangered species other than whales? 

 Answer: For fisheries the Hyperspectral and Lidar technologies might be useful. In 

 addition, some of the active acoustic technologies may have payoff to fisheries. In 

 that regard we have worked and plan to continue working with two NMFS Pacific 

 labs using acoustic techniques. Ocean and atmospheric modeling can also affect 

 fisheries in optimization of localization for fish stocks that track ocean features such 

 as fronts, or the survival of larval fish stocks as effected by phytoplankton density. 

 With respect to these technologies being useful for other marine mammals and 

 endangered species, the active acoustic technologies probably have the most hope 

 of being useful.
