There are innumerable bays, inlets and off-lying islands with an extremely complex seafloor. Deep trenches, shallow water shoal-infested areas, and rapidly changing depths provide a challenge to even state-of-the-art hydrographic survey systems. Reduced visibility in fog, ice-infested waters, isolation, and a short survey season make this coastal area one of the most challenging places in the world to conduct hydrographic surveys. Vast areas of the coastline have never been surveyed, and the majority of the areas that have been surveyed, do not meet modern hydrographic standards. This fact was recognized in the Neilsen's Annual Fishery Report of the Newfoundland Department of Fisheries in 1894 quoting "The existing charts are not reliable beyond Cape Harrigan, and it is a great peril to life and property that our fishermen venture into these unknown regions. An application to the Imperial Government for a vessel to survey this uncharted coast would, doubtless, receive attention. The work is urgently needed." The hydrographic surveys considered in this final field report were identified by clients, to meet their needs to improve the safety of navigation. The areas surveyed include (see Diagram 1 to 6 for geographic extent and location): 1. Entrance to Deer Pass through Caplin Bay. A multi-beam hydrographic survey was conducted to increase the density of existing soundings in this very narrow route. This information will permit scale charting for use by mariners when navigating in the passages between Harper Island, Stag Island, Big Island and Entry Island. 2. Hawke Bay. A single-beam survey was conducted from east of Pigeon Island to the bottom of Hawke Bay. This information will be useful for general navigation and for fisheries-related activity. 3. Entrance to Otter Bay. A multi-beam hydrographic survey was conducted to increase the density of existing soundings for larger scale charting. This survey covers the areas from Cape Bluff to Cooper Head, and includes the very protected areas of Snug Harbour and Lord Arm. 4. Passage through the Dead Islands. A single-beam hydrographic survey was conducted to open an inside route between Triangle Harbour and Duck Island. This passage will offer protection for small boats from heavy northeast seas. Canadian Hydrographic Service Atlantic 3 Final Field Report 2000 Labrador Surveys 5. Passage through Shoal Tickle. A multi-beam hydrographic survey was conducted to increase the density of existing soundings in this narrow route. This will permit larger scale charting and give the mariner an alternate route to St. Michaels Bay. 6. St. Michaels Bay. Multi-beam and single-beam hydrographic surveys were conducted to increase the soundings in this very narrow and shallow route: This information will permit larger scale charting and give the mariner an alternate route from St. Micheals Bay to White Bear Arm. 7. Bottom of White Bear Arm. A multi-beam hydrographic survey was conducted to increase the density of existing soundings required for larger scale charting. This information will be used for general navigation and fisheries-related activities. 8. Occasional Harbour. A multi-beam hydrographic survey was conducted to increase the density of existing soundings required for larger scale charting. This area provides excellent shelter against bad weather from any direction. It is also an excellent anchorage ground for vessels of various sizes. 9. Pinsent Arm. A multi-beam hydrographic survey was conducted to increase the density of existing soundings required for larger scale charting. 10. Coastal areas from Cape Bluff Island to Ship Head. A multi-beam hydrographic survey was conducted to increase the density of existing soundings required for larger scale charting of these coastal waters. This survey also included the well-protected summer station of Triangle Harbour and approaches, the summer station of Square Harbour and the continuation of the Entrance to Otter Bay. 11. Investigation survey at the Entrance to Fox Harbour. A multi-beam hydrographic survey was completed at the entrance to Fox Harbour. During the 2000 shipping season the MV Mokami, a medium size tanker carrying refined petroleum products, grounded while departing this port. The preliminary results of this survey indicate a shoal in the entrance to Fox Harbour. This shoal is shallower than charted by approximately 1.0 meter and may be where the vessel struck. As a direct result of this survey a Notice to Shipping and a Notice to Mariners actions have been issued to update the chart. Canadian Hydrographic Service Atlantic 4 Final Field Report 2000 Labrador Surveys DELIVERABLES The deliverables of the Matthew Phase II hydrographic survey in Labrador include cleaned and processed hydrographic data sets for use in production of nautical products, as listed in the table below. It is a policy of CHS (Atl.) Newfoundland that hydrographic data collected during a field season be processed, cleaned and delivered to the client in the form of new or updated nautical products, in time for the next year's navigational season. Tables 1 and 2 list these data sets and subsequent nautical products.

Canadian Hydrographic Service Atlantic 6 Final Field Report 2000 Labrador Surveys FIELD TRAINING For the duration of the Matthew Phase II Labrador survey, on-the-job training was provided to all hydrographers in the use and operation of the various sounding systems and processing software related to the survey. This training allowed hydrographers to become proficient in many aspects of the survey operations, which in turn, allowed flexibility in the development of a rotational staff assignment schedule. The schedule permitted hydrographers to be assigned a variety of tasks, avoiding the monotony of a long duty assignment. Field training consisted of two (2) days mentoring by a more experienced hydrographer. The trainees' work was closely supervised enabling them to easily call upon the mentor or Project Supervisor for support. Training was provided in the following areas: EM100 data acquisition session and the first step of processing in HDCS: -D. McCarthy EM3000 data acquisition session: D. McCarthy D.
