Water Column Mapping:  Water Column Mapping Michael Jech William Michaels NOAA Fisheries, NEFSC, Woods Hole, MA Mandate – Conserve and Manage Marine Resources:  Mandate – Conserve and Manage Marine Resources A Primary Management Objective: Develop sustainable harvest policies that minimize risks of overfishing target species (single species) and associated species (ecosystem). An Advanced Technology Objective: Apply AT in efficient and intelligent ways. HABITAT Two Broad & Overlapping Aquatic Categories: Pelagic (water column) Benthic (in or near the seabed) Fish Habitat:  Fish Habitat Products and Output:  Products and Output Population Estimates Culmination of survey design, measurements, biological data and areal or volume scaling. Relative Index (trend) and/or absolute estimate (numeric density) Resource Estimates Local density or abundance Spatial Distributions Temporal Data Biological Information (from net hauls) Age, Length, Biomass, Diet, Maturity, Species ID Clients: Fisheries Managers Commercial Fishers Academia Methodology – What does Multibeam do for us?:  Methodology – What does Multibeam do for us? Expands our view Improve detection of fish near bottom Increases sampling volume Improve ability to extrapolate measurements Improve mapping aggregations 1D & 2D  3D Improve detection of highly mobile fish Relative Index Requirements:  Relative Index Requirements Calibration to an absolute standard System stability & performance Comparison among surveys & among instruments Water column and seabed backscatter Optimally one instrument Dynamic Range: 120+ dB Scientific echo sounders: 120+ dB Data Compression Real time & post-processing Data Processing Real time & post-processing Data Visualization Real time & post-processing Motion Compensation Relative Index Req. (cont.):  Relative Index Req. (cont.) Position (vessel & towbody) Data Formats Open & available Meta-data FGDC, ICES --------------------------------------------- Species ID Volume Scattering (relative index) Volume integration Beam patterns Individual Target Strength Single target detection Absolute Estimate Requirements:  Absolute Estimate Requirements All ‘Relative’ requirements [# m3] = Volume scattering “Target Strength” Species ID Biological Information Partners:  Partners Instrument Manufacturers Data formats, instrumentation 3rd party software Data processing Visualization NOAA Computer Facilities Data management Data archive Meta-data NOAA Hydro & Fisheries Joint surveys Data sharing Academia (National & International) Data processing & analysis Ecosystem studies Regional Fish Priorities:  Regional Fish Priorities Northeast Groundfish Cod, haddock, pollock Spawning grounds on Jeffreys Ledge and Georges Bank Southeast reef fish, grouper Northwest Whiting, groundfish Alaska Walleye pollock, groundfish Southwest groundfish
