NMFS strives to better understand the effects of fisheries and environmental dynamics on ecosystems.  The AST supports this effort by:  1) identifying major sources of uncertainty in surveys or stock assessments; 2) addressing the major components of uncertainty in the acoustic survey method; 3) facilitating more efficient collection of multi-disciplinary data through the development of alternative survey platforms; and 4) conducting fisheries research and surveys using new technologies.  Through the process of identifying, refining, developing, and employing innovative sampling technologies, the SWFSC is better equipped to meet its stock assessment obligations, and staged to support survey technology development and use at other NMFS Centers.  AST projects are funded by the SWFSC’s Director’s Office, the FRD, the NMFS Advanced Sampling Technology Working Group (ASTWG), and other competitively obtained grant money.
