unit utilizes an oil-filled pressure case for the electronics to minimize design costs.

OML built and maintained a Baker sediment trap mooring in the Strait of Georgia near the Canadian Forces maritime Experimental Test Ranges (CFMETR). The mooring was deployed over a 0ne year period and serviced twice. Sediment samples and near bottom water were prepared for trace heavy metals analysis. Other services included oceanographic consulting and current meter data preparation and analysis.

Provided technical support services to oceanographic programs including design and manufacture of moorings and mooring subassemblies, service and calibration of mooring and profiling hardware and instrumentation, biological and chemical sampling, data collection by moored and towed data acquisition systems, at sea, and from the Arctic sea ice cover.

OML produced stem maps of four 2 ha study plots in the Kamloops Forest Region for root disease research. All positions of stems within the plots were located using laser surveying equipment and plotted using CAD software. Included in the maps are species, general health information and elevation loaded on layers within the drawings for inclusion in a comprehensive growth model.

OML performed development and integration of a sonar data aquisition package for M.I.T.'s Odyssey II class AUV. The system consists of two 100 kHz sidescan sonars and a single 120 kHz upward looking conical sonar. Data are collected and recorded as DOS format files on a hard disk. System control is provided by a PC104 format '386 imbedded computer.

OML conducted a drogue study of Sooke Bay, B.C. to provide current and circulation information for design and location of a fish trap for the T'souke Nation. Maximum spring tidal cycles were studied using DGPS positioning and 5 drifters.

OML built a remote independent hydrophone and seismic array data collection system for the Institute of Ocean Sciences. The system is capable of collecting data on ice fracturing events while deployed on the sea ice for up to a week at -40C. The system's total sampling bandwidth of 88.2kHz is frequency multiplexed for recording data from five hydrophones and five geophones. Environmental information was written to the video tape in the form of annotation on the audio channel.

OML developed and built a 2 channel 2500m fibre optic underwater data link for use with acoustic instrumentation at the Institute of Ocean Sciences. The uplink channel carries an NTSC video signal with up to 10 MHz bandwidth. Video formatted PCM data throughput is rated at 100 kbytes per second with error correction. There is also a bi-directional 9600 baud command, control and status channel. The underwater cable was built to also deliver 24VDC @ 3.5A to the remote electronics.

OML designed and built a five element 100kHz sonar array for accurately calculating wave spectra around an oil production platform in the North Sea. The work was carried out on behalf of LIC Engineering A/S doing research into hydrodynamic loads on slender structures in the North Sea.

Provided deep sea drifting buoy "tether-drogue" arrays, meteorological drifting buoy repair and design, construction and deployment of meteorological surface buoy moorings.

Conducted a water quality survey of Gastineau Channel and Lynn Canal, Alaska and provided consultation on implementation of a regular monitoring program. Also designed, built and deployed 2 instrument moorings and conducted 2 drifting drogue studies in Gastineau channel.

Designed, constructed, deployed and regularly serviced 16 current meter and sediment trap moorings in Stephen's Passage and Lynn Canal, Alaska. OML also implemented a water quality and bottom sampling program offshore at both AJ and Kensington mine sites.

Modified ULSAS instrument for deep water free drifting configuration. Rebuilt hydrophone array and main instrument package and developed deployment and recovery techniques for use at sea. OML also rebuilt the system for use with PCM format data and later rebuilt the whole system as a passive vertical line array instrument.

OML conducted a current meter mooring, water sampling and CTD profiling program at the proposed port and submarine disposal site at Punta Coloso for Minera Escondida. We were responsible for the design, construction, deployment and recovery of the two subsurface moorings.

Designed, fabricated, deployed and serviced long term moorings for collection of ocean current, tide, ocean structure and meteorological information, and participated in CTD, dissolved oxygen and plankton sampling.

Designed, constructed, deployed and processed data from 2 ARGOS current meters, Remote Expendable Velocity Stations (REVS), which collected and transmitted current data to satellite before and during MacKenzie River delta sea ice breakup.
