GGE5083, St. Andrews 2002

	Area Of Operations - GGE5083 Hydrographic Field Operations 2002 The principal area of interest for GGE5083 Hydrographic Field Operations 2002 was St. Andrews Harbour, New Brunswick. The approaches to the harbour and limited deeper water of Passamaquoddy Bay were also included in the multibeam survey. This area is situated in the North West of the Bay of Fundy.
Survey Design The harbour is very shallow, with depth ranges from -3.3m to +2m above chart datum. There is also a very significant intertidal influence. The tide in Passamaquoddy Bay is semidiurnal with a maximum amplitude of approximately 8 metres at spring tide. The main purpose of the project was to familiarize students with several components of a hydrographic survey such as data collection, data processing and error handling.

Survey Platforms and Instrumentation Survey Platform: This was the first year of operations for the CSL Heron, the Ocean Mapping Groups survey launch and all its sonar equipment. The students were ably assisted on board by initially, CHS's coxswain Carmen Reid. Loren Fleet, joined OMG staff and took over the responbility of the launch and its driving on a permanent part-time basis.

Objectives of Survey Although this survey is principally for training purposes the collected data will be used for several applications. The harbour of St. Andrews is a very attractive destination for boaters and other tourists within the summer months. Therefore it is of common interest to update the harbour seafloor to ensure accurate navigational information, especially in an area of such variable water depth and tidal currents. The strong currents in the area result in erosion and could cause the movement of subsurface objects. The final products of survey will also be provided to the City of St Andrews to support future decisions that are related to the harbour, such as dredging and the building of new docks.
The data gathered in this survey has been added to the previous surveys done in the general area over the proceeding ten years, giving very good and extensive coverage of what is a very interesting area , both in oceanographic and geological terms.
