Canadian Hydrographic Service Final Field Report 2005, W.R. Curran Revisory Survey INTRODUCTION
The 2005 revisory field season for Canadian Hydrographic Service (CHS), Atlantic Region, NL Division was to complete a number of high priority hydrographic surveys throughout the Island portion of Newfoundland and Labrador. These were shore based surveys resulting from requests received during consultations with local area users. The purpose of these surveys was to acquire hydrographic data for use in updating existing CHS nautical products, production of new products and, as required to increase marine safety. This program was able to be completed as a result of available funding through High Risk Charting Funds. Additional technical and mechanical support was provided by the Canadian Coast Guard, NL region. The Canadian Coast Guard also supplied the survey crew with a coxswain.
The Canadian Survey Launch W.R. Curran was utilized as the platform to carry out this program. The W.R. Curran is a single beam launch which was acquired through Program Integrity II funding by the Hydrography Division, Science Branch, DFO, NL, and has performed similar duties in previous survey seasons. It was an ideal platform for this program as the launch is easily moved and launched.
Launching CSL W.R. Curran.
In addition to hydrographic surveys, High Risk Charting Funds were used to install a shallow water side scan unit on the W. R. Curran. This unit was purchased and provided to the Newfoundland Office as part of a CHS national purchase under Program Integrity II funding. Until now, the installation of the side scan unit was not completed due to a lack of resources. The installation of the shallow water side scan on the W. R. Curran provided for more effective surveys. Using the side scan allowed the hydrographers to have a greater degree of confidence that no shoals or other hazards were missed between the lines of the W. R. Curran single beam surveys. This is a situation that has occurred historically in Newfoundland and Labrador and has resulted in a number of documented marine incidents in recent years. In Appendix A Figures 1, 2, and 3 demonstrate typical examples of the output obtained from the side scan unit.

PLANNING
In order to complete the assigned projects necessary preparations were made. Chsdir searches for each area were made and all relevant documents were ordered from Hydrographic Data Centre (HDC) for validation against our surveys in the field. Existing horizontal control was obtained from the Geodetic Service of Canada (GSC) database and from the Newfoundland and Labrador Pr ovincial Government (NPG) database. Vertical datum information and bench mark descriptions was obtained from the Marine Environmental Data Service (MEDS) database and the tidal section CHS Atlantic. Digital shoreline at best scale and topographic maps at best scale were obtained from the NPG Environment and Conservation Surveys and Mapping — Lands division.
This information was used to create mosaics which were used as the base for conducting our surveys and validation against other sources.
Canadian Hydrographic Service 12 Final Field Report 2005, W.R. Curran Revisory Survey RESOURCES AND PROJECT INSTRUCTIONS
Positioning System The positioning system used were Trimble 5700 GPS Receivers used in the Real Time Kinematic (RTK) mode using a locally installed reference station with corrections being broadcast by Pacific Crest UHF radios. Horizontal accuracy of the system was checked initially against other known control points in the survey area and then daily against a known shore point at each project location.
Sounding Data Soundings were obtained using a Knudsen 320BP pole mounted single beam echosounder at a frequency of 200KHz set to a fixed speed of sound in water of 1463m/s. Shallow water side scan data was obtained using Knudsen 320BP sounder and pole mounted sidescan staves with a frequency of 200 KHz. Soundings were corrected to portray true depth by using velocity profiles from an applied Microsystems SVP-16 velocimeter. Bar checks were completed and logged daily as a check of sounder performance.
Horizontal Control Existing North American Datum 83 (NAD83) horizontal control values were obtained from GSC and NPG control databases and were used as reference and check points in each of the survey areas.
Vertical Control Updated bench mark information was downloaded from the MEDS database. Other tidal information was supplied by the CHS Atlantic Regional Tidal Office. At each survey area the bench marks were inspected and levelled, new benchmarks were established as required and referenced to existing benchmarks. Bathymetry was reduced to sounding datum referenced to existing benchmarks. The survey party was supplied with two Sutron tide gauges.
Field Documents All field documents were produced via the HIPS/SIPS 5.4 SP1 and CARIS 4.4a SP5 processing system software in accordance with accepted procedures laid down in S.S.O. 2.2-94 and 2.8-84, and all other applicable regional directives.
Sounding Check Lines Sounding check lines were completed prior to the commencement of the regular sounding in accordance with S.S.O. 5.3-86.
Shoal Examinations Shoal examinations were carried out as stipulated in S.S.O. 5.3-86.
Fixed and Floating Aids Fixed Aids to Navigation were to be surveyed in accordance with S.S.O. 7.1-86. Floating aids were accurately positioned and compared to a corrected chart. Significant differences were reported as per S.S.O. 6.1-86.
Canadian Hydrographic Service 13 Final Field Report 2005, W.R. Curran Revisory Survey Sailing Directions The pertinent volumes of Sailing Directions were provided by the Regional Sailing Directions Officer (SDO) and were reviewed for our work areas as per S.S.O. 8.1-87. Consultations were held with the SDO prior to the start of our survey to determine any needs or Sailing Directions requirements in our survey area.

Sounding Datum was established by recovery of a previously established datum at Long Cove. A tide staff and Sutron tide gauge was installed and set to datum. Tidal data collected from 4 October to 17 November 2005 has been submitted to the Tidal Section at CHS Atlantic, BIO (Bedford Institute of Oceanography), Dartmouth, NS.
All soundings were positioned with GPS using Trimble 5700 GPS receivers in the RTK mode. The reference station used for this survey was NPG 82G3017. Position accuracy was verified against addition horizontal control points and by daily checks against known positions.
Shoreline features were collected with a Trimble Data Logger in conjunction with a Trimble 5700 GPS receiver used in RTK mode.
The survey Long Cove is 100% complete. A representation of the data collected is portrayed on field sheet number 1001504 at a scale of 1:1500 and has been submitted to and is at the Hydrographic Data Center (HDC), CHS, Atlantic, BIO. All source data and field notes have also been submitted and are archived. All previously existing documents have been field validated and returned to HDC.
A new sailing directions diagram is scheduled for production to be incorporated into sailing directions booklet ATL-102, Cape Bonavista to Ferryland Head (including Placentia Bay).
