27353 AFSC/RACE/GAP/McConnaughey: South Arctic Reconnaissance-2012-FFCPT Data Set Published / External 32487 AFSC/RACE/GAP/McConnaughey: South Arctic Reconnaissance-2012 Project Completed 2015-09-09 The Free Fall Cone Penetrometer Test (FFCPT) is a technique for geotechnical profiling of sub aqueous sediments. It was developed based on proven piezocone penetration test (CPT) theory and algorithms, with modifications to the manner of deployment and recovery. The instrument is designed to free fall through the water column, eventually impacting the seabed, recording penetration data at a high sample rate (2,000 Hz). This permits high resolution characterization of the sediment layering and material properties such as grain size and undrained shear strength. In addition to seabed characterization, the instrument can also be used for underway sound velocity profiling. The broad scope of the Essential Fish Habitat (EFH) mandate requires an efficient process for describing and mapping the habitat needs of federally managed species. For example, research indicates surficial sediments affect the distribution and abundance of many groundfish species, yet traditional sampling with grabs and cores is impractical over areas as large as the Bering Sea shelf. Acoustic tools are suitable for large-scale surveying and show great promise as a substitute for direct-sampling methods, but they have not been proven useful for EFH purposes. Acoustic seafloor surveys using different sonar systems were conducted along strong gradients of groundfish abundance, as determined from many years of RACE bottom trawl survey catches at fixed stations. Ultimately, the value of acoustic backscatter as a habitat defining character will be judged based on the statistical association between normalized backscatter and fish density. The benefits and costs of the different acoustic systems will be compared with data from multiple passes along the survey tracklines. Sediment samples, video and infauna collected along each trackline will provide additional biological and geological information for the analyses. Immediately following the Fishpac project during the summer of 2012, a single trackline was made between Dutch Harbor and Kotzebue Sound and various types of data were collected along the transit to get a glimpse at the seafloor habitat along the way. The points in this feature data set represent locations where the FFCPT was either deployed for seabed sampling as a groundtruthing tool or for SV profiling along the transit.

Instrument on-bottom times were called to the Sonar Lab from the fantail and a position was marked within QINSy navigation software. These positions were then extracted from the QINSy database and entered into a spreadsheet format and then imported into ArcGIS as a vector point feature dataset. 2012-09-01T00:00:00 Organization POP.Information@noaa.gov Mail_Address 27354 Entity gov.noaa.nmfs.inport:27353 Nancy Roberson 2015-09-22T16:10:44 SysAdmin InPortAdmin 2026-03-04T19:17:17 2019-05-31 Alaska Fisheries Science Center AFSC 7600 Sand Point Way N.E., Building 4 Seattle WA 98115 USA https://www.afsc.noaa.gov 0700-1700 Pacific Time 1001 Public No No 2019-05-31 1 Year 2020-05-31 Vector Entity point 25 NAD 1983 UTM Zone 3N 0.9996 -165.0 0.0 500000.0 0.0 coordinate pair 0.0001 0.0001 meter D North American 1983 GRS 1980 6378137.0 298.257222101 FFCPT OBJECTID Internal feature number.
