Demer NOAA-TM-NMFS-SWFSC-498 U.S. DEPARTMENT OF COMMERCE National Oceanic and Atmospheric Administration National Marine Fisheries Service Southwest Fisheries Science Center The National Oceanic and Atmospheric Administration (NOAA), organized in 1970, has evolved into an agency that establishes national policies and manages and conserves our oceanic, coastal, and atmospheric resources. An organizational element within NOAA, the Office of Fisheries is responsible for fisheries policy and the direction of the National Marine Fisheries Service (NMFS). In addition to its formal publications, the NMFS uses the NOAA Technical Memorandum series to issue informal scientific and technical publications when complete formal review and editorial processing are not appropriate or feasible. Documents within this series, however, reflect sound professional work and may be referenced in the formal scientific and technical literature. NOAA Technical Memorandum NMFS ATMO SP This TM series is used for documentation and timely communication of preliminary results, interim reports, or special ND HE A RI C C purpose information. The TMs have not received complete formal review, editorial control, or detailed editing. I A N D A E M I C N O I S L T A R N A T O I I O T A N N U . E S C .
