Science Consulting
Oceanography, acoustics, remote sensing, data analysis, technical writing
Services include instrument design; data analysis and graphic depiction of data using a wide range of scientific, analytical and animation softwares.
Emphasis has been on physical processes including the development of animations to depict time series. A sample of past projects has been compiled and is listed below.
Past Projects Remotely Operated Vehicle (ROV) Navigator
Trained as an ROV navigator for the Canadian Scientific Submersible Facility in May 2011. Participated as navigator for ROPOS dives during 24 hour operations for the NEPTUNE Canada and Venus July and September 2011 cruises.
ROV ROPOS deployment Navigation station for ROV operations
Methane Seep Greenhouse Gas Study
Designed flux funnel and carried out field research on the Mackenzie Delta to study methane flux from natural source methane seeps. Study has spanned 2006 through 2011 with field visits in the spring, summer and fall. Field investigations have included sonar and ROV surveys, gas chemistry sampling, hydrophone mooring deployments and sediment bearing capacity using a ground penetrating penetrometer (Pacific Geoscience Centre - Geological Survey of Canada).
Gas sampling of methane seep Flux funnel with instrumented chimney Hydrophone used to record bubble acoustics
Bubble Detection Algorithm
Developed a bubble detection algorithm to convert bubble acoustic recordings into gas flux based on a series of bubble amplitude and frequency thresholds (Pacific Geoscience Centre - Geological Survey of Canada).
Spectrogram of bubble acoustics from hydrophone recordings Spectrogram of bubble acoustics plus detected bubble events
Analyzed lake and river ice thickness using a Shallow Water Ice Profiler Sonar(SWIPS) on a northern lake and a river in the Ungava Peninsula. Time series analysis was carried out on both upward looking sonar data sets and a report of the results were supplied to the client (ASL Environmental Sciences for Environment Canada).
Developed a database and interactive data viewer for the 2007 & 2008 Mallik Gas Hydrate Research program (Pacific Geoscience Centre - Geological Survey of Canada). Carried out Sound-speed corrections for Ice Profiling Sonar (IPS) ice draft calculations for instrument deployments in the Beaufort Sea (ASL Environmental Sciences).
Animated TOPEX/Poseidon Sea Surface Height Anomalies for the North Pacific 1993 - 2010 (Institute of Ocean Sciences - Fisheries and Oceans Canada). See example below.
Modelled Gas Hydrate volumetric reserves based on adjacent well log geophysical data. Using ROCKWORK, calculated reserve volumes based on gas hydrate saturation thresholds.(Pacific Geoscience Centre - Geological Survey of Canada).
Calculated Sea Surface Eddy Areas enclosed by Haida and Sitka Eddies as determined by 10 and 15 cm height contours on images produced by Colorado Center for Astrodynamics Research (Institute of Ocean Sciences - Fisheries and Oceans Canada)
Gas Hydrate Seismic and Well simulation animations
Created process animations depicting seismic testing and theorectical gas hydrate extraction using thermal and pressure stimulation (Pacific Geoscience Centre - Geological Survey of Canada).Gas Hydrate Core Project
Created HTML catalogue of core photos & logs and extracted EMI data (Pacific Geoscience Centre - Geological Survey of Canada).Created an animation of the global El Nino and La Nina event. A series of composite satellite images were compiled to visualize the global influence of ocean temperatures due to the El Nino and La Nina (IOS).r animation.
Evaluated the software "Fledermaus" utilizing LIDAR data and orthophotographs to create interactive terrain fly throughs (Terra Remote Sensing Inc.).
Endeavour Hot Vents Area: A Pilot Marine Protected Area in Canada's Pacific Waters. Ecosystem Overview: Ecological, Social and Economic Components.
