Seafloor Systems Inc.

Specifics of work: Hydrone and EchoBoat ASV R&D work entailed the integration of several open-source software- and hardware components, including Pixhawk, Ardupilot, and Mission Planner. Building prototype involved everything from electro-mechanical construction considerations to familiarization with the Eclipse IDE and the Github collaborative repository. In hydrographic survey work, sonar data acquisition equipment used has included Teledyne-Benthos C3D interferometric sonar, several Kongsberg-Simrad multibeam systems, and a variety of GPS and IMU equipment. Software used for data collection and processing has included the Hypack Suite, Isis, Kongsberg-Simrad SIS, and a great variety of general mathematical- and image-processing tools including Octave and Matlab, UNIX tools such as AWK, and Photoshop, Excel, etc. Data-conversion work involved physical-oceanographic considerations of the problems, deriving the mathematics of proper conversion, and writing AWK script and C programs to convert the originally-recorded data files. Work in Alaska included mechanical design of vessel equipment mounts as well as interfacing of Teledyne-Benthos C3D sonar, Coda-Octopus F180 navigation gear, Timenet time server, Leica RTK survey equipment, Valeport tide gauge, and other equipment, in a first-time site/vessel deployment. Follow-up data processing work included sophisticated mathematical modeling of tides (~30 ft amplitude) to correct for operational errors and to improve bathymetric accuracy. Work in the Gulf of Mexico included setup, operation, and extensive field engineering work on Kongsber-Simrad EM 710, EM 1002, EM 2000, and EM 3002 multibeam systems, associated SIS acquisition software; Benthos SIS-1000 sidescan/sub-bottom system (and associated Isis acquisition software); Coda F-180 GPS/MRU. Work involved power supply engineering, firmware modification, and both analog- and digital electronics repairs and modifications to sonar systems, and electrical and mechanical work on hydraulic winch. For survey work in southeast Caribbean, worked with Benthos 1624, Edgetech 4200, and Geoacoustics sidescan sonars, Geometrics 881 and 882 magnetometers, Kongsberg/Simrad MRUs, Reson 8125 multibeam sonar, and many other systems whose hardware and software required considerable attention. Inland work in Tennessee included interfacing Benthos C3D sonar, Hypack software, Seatex MRU, and CSI Vector GPS/heading sensor. Equipment used for cable landing surveys in Alaska included Reson 8111 multibeam sonar, Applanix POS/MV navigation system, Geoacoustics 159 dual-frequency and Datasonics SIS-1000 sidescan and sub-bottom sonars, and Seabird Electronics SBE 19 CTD; beach topographic survey was accomplished using Ashtech RTK survey equipment with Pacific Data Link radio modems. In general these jobs demanded electronic-technical as well as mechanical resourcefulness.

Williamson & Associates

Specifics of work: Most recent work aboard Mermaid Vigilance involved component-level trouble-shooting of a "legacy" multi-channel analog sidescan sonar system operating in depths over 5000 meters. Work also afforded the opportunity to gain considerable familiarity with variable-displacement hydraulics and associated electro-mechanical controls of Dynacon winch used for towing sonar vehicle. Work with W & A hydroplow telemetry system, whose core components comprised DOS Stamp CPU, GP3 A-D modules, 232SPDA A-D-A modules, cameras with Axis video servers, and Tritech and Blueview sonars, included spectral analysis of DSL comm's and circuit modifications to achieve noise immunity and additional functionality, improvements in Visual Basic code for display and control, production of schematics and system block diagrams, and miscellaneous mechanical/fabrication work. Interferometric sidescan survey equipment includes 30- 60- and 120 kHz analog systems, the electronic details of which became quite familiar to me. Worked with Ultra Short Baseline Array positioning systems involving chase boats and data radio links. Much reverse-engineering and improvisation done on various electronics, including SeaSpy magnetometers, RF equipment, and general power- and signal interfaces.

Work included setup and interfacing of instrumentation as well as data-processing work with "trajectory" (position and attitude) files using UNIX AWK. Bathymetric- and sidescan survey was accomplished using Hypack/Hysweep software and Benthos C3D pole-mounted on 36-ft aluminum catamaran survey vessel and on 32-ft aluminum monohull survey vessel, and using Ross Sweep system of single-beam transducers on a unique shallow-water rib boat with floating transducer booms, and on a jet-ski watercraft outfitted with single-beam sonar, on-board computer and GPS. Navigation was by Leica RTK and Pacific Crest radio modems in conjunction with POS/MV MRU in the case of the multibeam survey boat, and in conjunction with Seatex MRU and CSI Vector Sensor in the case of shallow-water sweep boat. Work included electronic, mechanical, and software aspects of setup, standard remote-area river survey and boat operations, and data processing using Hypack multibeam editor. Certain software errors relating to motion-correction of sonar data, affecting a great number of users in the hydrographic community, were discovered and correction software was written in C programming language, after an interim correction was developed using UNIX utilities. The jobs incidentally included some boat-electrical and mechanical work on Volvo Penta mains and generator engine.
