The NOAA Pacific Islands Fisheries Science Center (PIFSC) Stock Assessment Program (SAP) is responsible for regularly assessing this stock. To augment and improve the data used in the Deep7 assessment, PIFSC began developing a multi-gear Bottomfish Fishery-Independent Survey (BFISH) for the Deep7 stock in the Main Hawaiian Islands (MHI) in 2011 (Richards et al., 2016). Benthic habitat has been shown to play a key role in determining the spatial distribution of demersal living marine resources (Richards et al., 2012). The BFISH survey employs a stratified random sampling design based on depth and habitat. Prior to the work presented here, the lack of usable backscatter data across the entire MHI domain was a major impediment to the development of a properly stratified operational fishery-independent survey covering the full domain of the stock. While backscatter data had been collected throughout the MHI, these data were collected using various platforms and sensors such that numeric backscatter values from disparate areas did not represent similar levels of substrate hardness. This precluding development of a comprehensive survey stratification across the MHI domain of the Deep7 stock. To remedy this situation, the NOAA Pacific Islands Fisheries Science Center conducted a one-year project to create comprehensive, high-resolution, synthesized depth, slope, and seafloor hardness maps and GIS layers for the Main Hawaiian Islands. This paper describes that effort in two parts: 1. Part I: Methods and results pertaining to the development of a 5-meter resolution Main Hawaiian Islands bathymetric and backscatter synthesis covering depths of 75 to 400 m; 2. Part II: Novel methods and results associated with the use of these newly created synthesis data in quantitatively defining effective habitat strata ratification for the NOAA PIFSC Bottomfish Fishery-Independent Survey in Hawaii (BFISH). These data products will be used for experimental design and stratification of teh Pacific Islands Fisheries Science Center (PIFSC) Bottomfish Fishery-Independent Survey in Hawaii (BFISH) as well as to investigate physical factors correlated with distribution of Hawaiian bottomfish species. completed Richards, Benjamin L (808)725-5320 1845 Wasp Blvd. Honolulu HI 96818 USA benjamin.richards@noaa.gov Email or phone (808-983-5320) pointOfContact Richards, Benjamin L (808)725-5320 1845 Wasp Blvd. Honolulu HI 96818 USA benjamin.richards@noaa.gov custodian asNeeded OBSOLETE theme PARR EXCLUSION Deep-7 bottomfish FRMD PIFSC SAP advanced technology backscatter bathymetry bottomfish depth multibeam slope stock assessment theme 2016 temporal Kahoolawe Kauai Lanai Main Hawaiian Islands Maui Molokai Niihau Oahu Penguin Bank place DOC/NOAA/NMFS/PIFSC > Pacific Islands Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
