The History of the CHS Central & Arctic Region
1976-1977
1976 – Highlights
The Canadian Hydrographic Service has, until this year, had three regional offices located at Victoria, Burlington and Dartmouth. A further regional office is being established. Known as the Laurentian Region, it will have its office in Quebec City. The Headquarters, under the Dominion Hydrographer, is located in Ottawa.
A significant development during the year was the decision to accelerate the pace of decentralizing staff and certain operations from Ottawa to the regions. The largest group to be moved during the next three years will be chart production. In the case of Central Region, the existing cartographic staff will be increased from two to at least twelve during the decentralization period.
An unusual and important field operation during 1976 was the management of a combined bathymetric and geophysical survey off the coast of Senegal and Gambia, West Africa. Funding for this operation was provided by the Canadian International Development Agency (CIDA). CSS BAFFIN was provided by the Atlantic Oceanographic Laboratory and the work was conducted jointly with other scientific groups at the Bedford Institute, in particular, the Atlantic Geoscience Centre. The results of the surveys are being used to provide Senegal and Gambia with a set of bathymetric, gravity and magnetic maps and a comprehensive report. The field operation was notable in completing its objectives given a very short notice.
In the realm of technical development, two projects were outstanding. Both were partially supported through the Unsolicited Proposal Fund of the Department of Supply and Services which is directed towards the development of innovative ideas by industry. The major project was the development of a system, utilizing a tracked vehicle for sounding in ice covered waters. That contract was awarded to Banister Technical Services, Edmonton. The second was a Tidal Acquisition and Telemetry System (TATS). The system, which incorporates a microprocessor, promises to revolutionize the systematic collection of water level data.
Hydrographic Surveys
A survey Channel was made of the Belcher Channel situated in the Arctic Islands between Cornwall and Devon Islands. The channel is named after Sir Edmund Belcher, who led the last and greatest search expedition sent out by the British government to search for Sir John Franklin. The channel is critical to navigation as it lies on the route that ships must take from Jones Sound to King Christian Island. The latter is the site of a major natural gas field and there has been considerable discussion on the use of liquefied natural gas (LNG) tankers for exporting the resource from that point. There has also been a proposal that a pipeline may cross the Belcher Channel as one means of exporting the gas from King Christian Island to the south. The survey utilized three chartered helicopters provided by the Polar Continental Shelf Project under a commercial contract. These worked out of a base camp situated on the channel ice. During the period of the survey from March to May, the area was ice covered with ice approximately two-metre thickness. Through-ice sounding methods were employed and a record 8,705 spot depths were measured. In addition to the helicopters, an experimental sounding system using a BOMBI tracked vehicle was used. In the end, a shipping corridor 10 kilometres wide was delineated and sounded with measurements on a square grid of 500 kilometres to ensure that there were no obstructions.
A similar type of survey to that of Belcher Channel was conducted during February to April in James Bay. The program is a joint program of the CHS and the Gravity Division of the Department of Energy, Mines and Resources with some participation of the Research and Development Division of O.A.S. Central Region. The program provides regional gravity coverage and reconnaissance bathymetry in the shallow coastal zone of James Bay and Hudson Bay. This area would be difficult to systematically survey by ship. During 1976 a total of 1,479 gravity measurements and 1,169 soundings were taken on a 6 kilometre square grid. This completes the systematic mapping of James Bay.
As mentioned earlier in the highlights on the survey of the continental margin of Senegal and Gambia, West Africa using CSS BAFFIN, a major feature of the survey was the establishment of an Accufix electronic positioning system (miniature Loran-C). The system was integrated with a Satellite navigation receiver to provide precise positioning over the survey area, which extended 300 miles off the African coast. The Accufix system was provided under a commercial contract. The main program consisted of measuring depth, gravity and magnetism along east west lines. A total of 29,454 kilometres of depth measurements, 28,568 kilometres of gravity and 28,568 kilometres of magnetics were collected. One part of the program involved the use of a Huntec Seismic System in the area between the 2,000-metre depth contour and the coast. Bathymetric data for the General Bathymetric Charts of the Oceans (GEBCO) program were taken across the Atlantic.
Although the St. Lawrence River is the most important thoroughfare in Canada, the charts are made from surveys dating back to the earlier part of the century. To overcome this shortcoming, a major re-survey was initiated in 1969. The survey this year completed the program to provide new data from Quebec City to Pointe des Monts on the St. Lawrence estuary. New metric charts can now be produced. Although the depths in the critical shallows proved to vary little from the existing chart, a difference of 30 metres was found in the deep water. This is perhaps not surprising since the existing chart includes data gathered as long ago as 1885. An interesting note of the survey was measurements over the wreck of the EMPRESS OF IRELAND, which sank in 1914 off Pointe au Pere. The wreck lies in 40 metres of water with 21.6 metres depth over it. The total survey was highly productive with 19,188 kilometres of soundings run and 59 shoals examined. Survey equipment included a Minifix chain and the INDAPS automated system was installed aboard the survey vessels. These included ADVENT, a fast 77-foot crew type vessel, NUCLEUS a 34-foot Nelson launch and a 25 foot HYDRO class launch.
Lake Superior – the systematic offshore surveys of the Great Lakes were interrupted this year to respond to a request by the Ministry of Transport on behalf of an U.S. Board of Enquiry. The request was to survey in detail an area between Michipicoten and Caribou Islands in Lake Superior where it was thought that the lake carrier EDMUND FITZGERALD might have touched bottom prior to foundering in November 1975 with the loss of all hands. The existing chart is comprised of surveys dating back to 1919 and 1920. A number of shoals exist to the north of Caribou Island and in the channel between it and Michipicoten Island. The survey, which included lines run as close as 25 metres apart in critical areas, revealed no significant changes. CSS BAYFIELD was used for the work and was positioned by a Minifix chain. Data were recorded and processed by the INDAPS automated system.
In Lake Huron, a continuing co-operative program with Environmental Management Service has been the Limnogeological surveys of the coastal zone around the Great Lakes. The program, which started in Lake Ontario has moved through Lake Erie and in 1976 started in Lake Huron with the coastal strip between Sarnia and Goderich. The data which includes depth profiles and bottom samples from the water’s edge to the 20 metre depth contour provide the geologists with information on the littoral drift and the hydrographers with a systematic reconnaissance and review of the existing charts. The profiles for the geologists are 1000 metres apart and are subsequently interlined to 500 metres for hydrographic use. During 1976, 1,100 square kilometres were surveyed. The 44-foot launch was used for the survey with Motorola RPS and Miniranger systems providing the positioning. Support for the geological survey was provided by CSS LIMNOS and the chartered tug LAC ERIE.
Revisory Surveys – The high rate of urban growth and the active development of recreational areas within Central Region makes it necessary to carry out an active program of chart revision. Information is provided by a cyclic program of revisory surveys. Two crews are deployed each year to examine the charts along a particular strip of coastline. During this year one crew aboard CSL VERITY was active in the Richelieu, Rideau and Trent Severn canal systems and extended operations into Georgian Bay north to Parry Sound. The second crew in CSL VEDETTE examined the charts in the Lower St. Lawrence. This included a large-scale survey to examine some reported changes at Sorel, P.Q.
This was the second year of multiparameter surveys in Hudson Bay. Once again this survey is a co-operative effort of the Hydrographic Service with the Gravity Division of DEMR. Depth, gravity and magnetics are measured simultaneously. The 250-foot CCGS NARWHAL was provided for the fifth year in succession by the Canadian Coast Guard, MOT. The ship has been fitted with an integrated satellite navigation and doppler sonar system to provide positioning accuracy to better than 250 metres over the entire area. The operation will extend over a number of years with each year’s data contributing to the density of the survey. NARWHAL entered Hudson Bay on the early date of July 21st. The off-shore program had to be terminated earlier than usual as the ship had to be used to recover some current meters that could not be picked up by the chartered vessel PETREL which had broken down. During September, NARWHAL was dispatched to Povungnituk where, assisted by the launch SURGE, it completed surveys of the channel into the port.
James Bay Coastal – Very few of the harbours in Hudson and James Bays are adequately charted. Paralleling the offshore program is a program to carry out detailed surveys of the ports. This will be followed by surveying coastal corridors to connect the ports. There are a number of outstanding requests to survey the ports on the west side of Hudson Bay. Unfortunately, the lack of a ship this year eliminated plans to survey Eskimo Point and Whale Cove. Instead, the Hydrographic Service responded to a request from the Moosonee Transport Company for surveys of Attawapiskat and Fort Albany on the west side of James Bay. These are two small Inuit settlements that are partially supplied by tug barge units. The coastline is muskeg and the riverbed is reported to be continually changing. Due to the very shallow water, it was necessary to work only during the higher stages of the tide. Monark launches, powered by twin outboards were used. A particular problem was caused by the squat of these craft as they increased speed.
Ships and Launches
Once again CSS BAYFIELD was outfitted for hydrographic survey operations in Lake Superior. With very few ports of refuge in that area except for Quebec Harbour on the south shore of Michipitocen Island, it was decided the vessel would shelter there in bad conditions. Every second weekend BAYFIELD proceeded to Sault St. Marie to replenish her stock of fuel and supplies. During the season BAYFIELD broke away from normal operations and proceeded to Lake Ontario to participate in the Kingston Sailing Olympics. During this period, senior officials from Central Region and Ottawa visited the vessel. The highlight for BAYFIELD during this visit to the Olympics was on July 7, when the Captain welcomed aboard Prime Minister Trudeau, Mrs. Trudeau, their son Justin and other members from the Prime Minister’s Office. After a buffet luncheon, the vessel proceeded to the racing area escorted by the R.M.C.P. patrol vessel BRULE and remained there for the afternoon, after which it then proceeded back to Richardson Wharf at Kingston so that the dignitaries could disembark. After five days at the Olympics, BAYFIELD returned to Lake Superior to once again take up her role in Hydrographic Surveys. After steaming a total of 12,216 nautical miles, of which 5,115 were running sounding lines, BAYFIELD returned to Burlington for winter lay-up with another successful season completed.
CSL VEDETTE, which had wintered at Hamilton was brought to Burlington and made ready for revisory surveys in the Lower St. Lawrence. On May 8, VEDETTE left Burlington to join the survey party at Sorel, P.Q. Revisory surveys continued in this area throughout the summer months and the launch and equipment returned to Burlington on September 24 with another successful season completed.
CSL VERITY was outfitted at Burlington for this program and after a week’s delay due to high winds, sailed to the Richelieu River to participate in revisory surveys. From Chambly, Quebec, the launch upriver, then proceeded through the Ottawa River and Rideau River to Kingston on July 9, when it was reassigned to the Kingston Olympics. At Kingston VERITY was used as a meteorological support craft for the Olympic races. Upon release from this program, VERITY proceeded to Trenton rejoining the Revisory II survey there through the Trent Severn Waterway and north to Parry Sound in Georgian Bay. On October 8, VERITY returned to Burlington with the season completed for another year.
CSS ADVENT, CSL NUCLEUS, HYDRO IV and a Boston Whaler provided support for the Lower St. Lawrence River survey. All vessels arrived in Rimouski on May 16. Surveys continued in the Rimouski area until August 3. At that time the base camp, all vessels and equipment were moved 45 miles down river to Matane, P.Q. On August 26, after completing 6,480 miles of sounding, ADVENT was released from the survey and set out on the homeward journey to Burlington arriving at CCIW on September 1. While in transit, ADVENT spent a day at Quebec City to demonstrate survey systems and equipment to the local branch of the Canadian Institute of Surveying. Meanwhile, the Lower St. Lawrence survey continued with the remaining launches until October when the survey was terminated and all equipment and launches were returned to Burlington.
Hudson Bay Offshore Survey – For the fifth consecutive year, CCGS NARWHAL was made available for Northern Surveys. The vessel was dry docked on July 5 for the installation of new transducers. Following three days in dry dock and loading of equipment, NARWHAL departed Dartmouth, N.S. on July 15 and proceeded to Hudson Bay where the launch SURGE, a Boston Whaler and survey equipment were off-loaded for the Povungnituk survey party. During the season, NARWHAL ran a total of 14,817 miles of sounding lines in Hudson Bay and after recovery of the Povungnituk equipment returned to Dartmouth where all launches and equipment were unloaded and returned to Burlington.
Povungnituk Survey – After trials at Burlington, SURGE was transported to Dartmouth where further trial runs proved SURGE to be in good operational condition. Once in Povungnituk, mechanical problems from the outset of this survey plagued SURGE. A Cummins mechanic and parts were flown in to the site to effect repairs which were finally completed. However, very little survey work was done as a barcheck chain fouled the propeller crippling the launch once again. With no lifting capacity facilities available, SURGE and equipment once more were loaded onboard NARWHAL and returned to Dartmouth.
James Bay Survey – A request for two 21-foot Monark launches for James Bay involved the task of transporting the launches from Churchill where they were stored after the 1975 season, back to Burlington. After the launches were equipped with new engines, they were loaded along with one Boston Whaler on railroad cars and shipped to Moosonee. From there they were transported to Attawapiskat, arriving on the survey site on July 14. The survey areas were a rock strewn, turbid nightmare and were undeniably some of the most difficult areas to operate survey launches. At the end of the season eight of the ten new engines were damaged to the point where they were unserviceable. On September 16, following the completion of surveys at Attawapiskat and Fort Albany, the boats were stored for shipment to Burlington in January 1977, via tractor-train and railroad.

1977 – Highlights
As in past years, the Region was engaged in a multitude of activities and completed all commitments although hampered by a reduction in man-years for field operations together with escalating costs and a slightly diminished budget. Some field programs, particularly in the northern regions, are rapidly becoming prohibitive in costs and resources. A diminished or even static budget coupled with the cumulative effect of man-year reductions in 1978-79 will seriously jeopardize some northern programs. In one case, the joint EMR-DFO Winter Bathymetric/Gravity survey of James Bay/Hudson Bay has caused the Region to cancel the survey for the winter of 1978/79.
We have aided in the establishment of a Quebec Region during 1977 by transferring staff members and by supplying several fully equipped launches and survey systems.
Regional highlights in 1977 were the Canadian Hydrographic Conference held by the Region in March, with the Deputy Minister, Blair Seaborn giving the opening address and Admiral Haslam, Hydrographer of the Royal Navy speaking at the Conference luncheon on Hydrography and the North Sea. Later that month, the Director was appointed to the Executive and the Commonwealth Survey Board of Education of CASLE (Commonwealth Association of Surveying and Land Economy). Cooperative charting by U.S. National Ocean Survey and the Region resulted in a general chart of Lake Ontario produced by Canada and one of Lake Erie produced by USNOS. Much appreciated visits of MOUNT MITCHELL (USNOS) to CCIW. The publishing of the FIG Working Group 414a report on Data Systems was completed in September. That month also the Regional Hydrographer, A.J. Kerr, left us to pursue a Masters Degree in International Law and Policy at the University of Wales.
During 1977 the CCIW Executive Committee commenced meeting each month and started to tackle important inter-service issues. In November 1977 the Director was elected to preside over the CCIW Executive Committee for 1978, recognition of the tri-service occupancy and involvement at the Centre.
Additional Hydrographic highlights were the development of a sector scanning sonar for through ice surveys and the completion of the Tidal Acquisition and Telemetry System project, with one prototype already in service. With the establishment of a Cartographic Section, Cartographers are presently involved in processing 22 nautical chart editions and twelve new nautical charts.
Hydrographic Surveys
1977 field activities in the north included winter surveys in Viscount Melville Sound, and the Belcher Islands of Hudson Bay, and summer operations both offshore and inshore, at Eskimo Point and Whale Cove in Hudson Bay. Southern areas surveyed included the Winnipeg River north of Kenora, various areas in Lake Huron, eastern Lake Erie, and on a revisory basis, Lakes Ontario, Erie, Huron and the Upper St. Lawrence River.
Early in 1977 two winter projects were carried out, one in the high Arctic and the other in Hudson Bay. Both were cooperative projects with the Earth Physics Branch of E.M.R. The Arctic survey with the Polar Continental Shelf Project utilized four helicopters and two tracked vehicles to survey the entire western portion of Viscount Melville Sound including the bays of northern Victoria Island. Through Viscount Melville Sound a shipping corridor 30 kilometres wide was surveyed with a closely spaced grid. Bridport Inlet on Melville Sound (which is of great interest to Petro Canada for a liquefied natural gas terminal) was surveyed in detail using the tracked vehicles. The Hudson Bay winter program operated in the area south and east of the Belcher Islands where soundings and gravity observations were made on a 6-kilometre grid.
An active and very productive program was maintained in Hudson Bay with two major vessels operating during the summer months. The offshore multi-parameter survey of the Bay continued using the Ministry of Transport vessel CCGS NARWHAL. On the western side of the Bay, the chartered ship PETREL completed detailed surveys of Eskimo Point and Whale Cove, as well as a corridor from Marble Island to Walrus Island.
In the Great Lakes five projects were conducted in 1977. A survey of the eastern end of Lake Erie was completed which will provide up-to-date data for the proposed new international confluence chart of this area of the lake. The data will be used to compile the approved strip chart of this area. In southeastern Lake Huron work was carried out in conjunction with inshore surficial geological studies. The program was further expanded to provide sufficient data for the southern Lake Huron confluence chart as well as the coastal strip charts.
A survey of all the waters in northern Lake Huron was undertaken in cooperation with the U.S. National Ocean Survey. The Americans utilized their ship MOUNT MITCHELL to survey the offshore areas. A close liaison was maintained with our U.S. counterparts and on two occasions the two ships rendezvoused to ensure that the sounding and positioning systems were correlated. The program will provide data for the general chart of the lake, the confluence chart of the northern end of the lake and for the small boat strip charts of southern Manitoulin Island. The offshore portion of the survey was completed but work remains inshore.
The cyclic program of revisory surveys was conducted again. The large survey launch VEDETTE worked in Lake Erie, Lake Huron and Georgian Bay and VERITY worked in Lake Ontario on the Upper St. Lawrence River. The VEDETTE survey also positioned all navigational ranges within its area of operation. The VERITY survey had an additional project of expanding the limits of the 1975 Toronto Harbour survey to complete coverage of the new harbour chart.
Our most westerly survey was on the Winnipeg River where coverage for one chart from Keewatin to Minaki was completed. This survey party operated under the unusual conditions of all-time recorded low water levels on the river.
As part of a continuing program, Central Region and NOS, Norfolk, Va. exchanged technical staff for participation in and exposure to respective programs and techniques.
Contract personnel were used for collecting data and operating the Decca chain on the Hudson Bay winter program.
Ships and Launches
Ship Division provided ship and launch support to both hydrographic and scientific field parties from the Winnipeg River, at Kenora, to the lower St. Lawrence and northward to Hudson Bay. In addition to the chartered vessels M.V. PETREL V and M.V. LAC ERIE, the DOT vessel CCGS NARWHAL was once again acquired for the northern surveys in Hudson Bay.
With the transfer of two Botved launches and two Boston Whalers to the Quebec Region, Ship Division welcomed two new Nelson 34 foot launches to the fleet. These launches NIMBUS and NAUTILUS arrived at Burlington late in December and will be ready in the spring to join the work force.
Major modifications to CSS BAYFIELD were carried out throughout the winter months. Two new masts were installed, also a new lab as well as a new HIAB crane capable of a one ton lift at five-metre range. BAYFIELD departed Burlington on May 11 and proceeded through Tobermory where the vessel operated relatively trouble free throughout the season participating in hydrographic surveys for two-week periods and returning to Tobermory on the second weekend to refuel and replenish stores. The vessel returned to Burlington on October 28, after completing 171 operational days and steaming a total of 14,122 miles. On the same program the launches NUCLEUS and HYDRO IV participated throughout the summer months. NUCLEUS performed well on this survey with very few days lost due to mechanical breakdown. HYDRO IV was replaced by HYDRO II late in the summer, due to lack of speed and excessive exhaust fumes.
The Winnipeg River survey based at Kenora, Ontario and supported by CSL WOODCOCK, which was transported from Selkirk to Kenora. In addition, two Botved launches, HUNT and HUSTLE and the tunnel drive PACER were road transported from Burlington arriving at Kenora on May 11. Once again the very popular launch WOODCOCK was the workhorse of the field party. Although WOODCOCK had a fair share of mechanical problems, it was still the favorite launch on this survey. CSL PACER had a fair workout this season and reports are that the launch was highly maneuverable and comfortable and proved to be an excellent craft for visual fixing due to low cabin structure. Launches and equipment to Burlington at survey end on September 21.
Revisory Surveys were away to an early start and continued throughout the summer months. CSL VEDETTE supporting Revisory I in Lake Huron while CSL VERITY operated from Beauharnois to Toronto and down the south shore of Lake Ontario to the Niagara River. As VEDETTE was no longer required on Revisory I, it was returned to Burlington early in August and a Boston Whaler was used to complete the survey. Revisory II continued to work in the Toronto area along with one Botved launch on a harbour survey until November when all launches and equipment were returned to Burlington.
Based at Port Dover, the Lake Erie survey was supported by CSS ADVENT and CSL HYDRO II, which was replaced in August by a Botved launch and a 21-foot Monark. Positioning problems were the main cause of delay on this survey. However, ADVENT ran a total of 8,148 miles during the season with 183 operational days of which 94 were spent at sea. On August 22, ADVENT had the misfortune of striking a submerged object, damaging both propellers and two days were spent at Erieau for repairs. On October 23, the survey was terminated for the season and ADVENT returned to Burlington where it was used for Loran C tests until November 28 when the vessel was withdrawn from service for the winter months.
The charter vessel M.V. PETREL departed for the first scheduled cruise on Lake Ontario on March 15. High winds and heavy ice conditions made a very difficult passage and only part of the first cruise was completed. During the early part of the season, PETREL participated in various scientific programs on Lakes Erie and Ontario and after outfitting the vessel sailed for Hudson Bay on July 13. New davits were installed during the winter months to accommodate two Botved launches, which were used for a hydrographic survey in Hudson Bay. The hydrographic survey continued using PETREL for both survey vessel and mother ship for the launches until September 18, when the hydrographic crews disembarked at Churchill and R&D personnel from Central Region equipped the vessel for an oceanographic program. With this program completed, the vessel departed on the homeward voyage on September 29. After off-loading survey launches and equipment at Quebec City on October 7, the vessel then proceeded to Burlington arriving here on October 14. On November 19, PETREL once again proceeded to Lake Huron where the vessel was used to evaluate Loran C for the purpose of overland pattern errors returning to Burlington again on November 26 for winter lay-up.
Once again Ship Division acquired the services of CCGS NARWHAL for the Hudson Bay offshore survey. NARWHAL after dry-docking and outfitting for hydrographic surveys, departed Halifax on July 23 and continued operations in Hudson Bay until September 30 when the vessel departed, arriving Halifax October 9.
