This course aims to provide the theoretical foundations and practical field experience in order to enable hydrographic surveyors to execute hydrographic surveys, to monitor and evaluate survey data quality. The job profiles of graduated students are targeted on :
– Watch leaders positions on a large survey operation (nautical charting surveys, off-shore surveys)
– Hydrographic surveyors on survey units deployed for localized survey operations (ports, coastal engineering surveys, inland waters, survey launch in support of a large scale survey operation).
The learning outcomes of this course are :
- Knowledge of the marine environment in the context of a hydrographic survey;
- Knowledge of operation principles of hydrographic system components (Single Beam and Multi Beam Echo Sounders, Positioning systems, Inertial Navigation Systems, Tide measurement sensors and systems, Undersea systems (positioning systems, autonomous underwater vehicles, remote surveys systems, acoustic imagery systems) and data quality assessment;
- Ability to set-up a hydrographic system in a survey vessel, awareness of data quality required by hydrographic instructions;
- Execution of a hydrographic survey within a specified level of data quality and in compliance with safety rules;
- Execution of data processing tasks using dedicated software for the production of hydrographic products (geo-referenced digital sea-floor models, acoustic imagery).
1- Course modules :
- Bathymetry – This module describes all sensors used for measuring depths, including single beam and multibeam echo sounders, bathymetric LiDAR.
- Hydrography – Hydrographic surveys and applications are detailed and hybrid measurements systems dedicated to hydrography and detailed together with appropriate methodology for quality assurance and quality control.
- Environment – Ocean environment is presented from the geological and oceanographical point of view, as well as their incidence on the way to conduct hydrographic surveys.
- Geodesy and spatial referencing – This module presents the technique for transforming relative bathymetric measurement into absolute geodetic frames.
- Positioning – A module on at sea positioning with advances GPS techniques and underwater vehicles positioning using acoustic methods.
- Tide and water levels – Presents the physics of tide raising forces, tide prediction, and tide measurement methods.
- Hydrographic data management – This module details the methods for hybrid sensor system data processing, from raw data to soundings.
- Nautical Science – A course on safety at sea and safe practice of hydrographic surveying.
- Law of the sea – Legal aspect of hydrography, delimitation, boundaries, legal liability of the hydrographer, contracts.
MODULES LINKS AND EVOLUTION :
2- Hydrographic survey project (7 weeks), on the Saint-Lawrence River at Rimouski, Québec, Canada.
Foreign students: You will need a visitor visa during the period of stay in Rimouski. Please make sure you are eligible for such a visa before registering for the course. No refunds will be made in the event of your inability to obtain a visitor visa to Canada for the field training period. Also note that participation in the field project is mandatory in order to complete your degree and obtain your certificate attesting the successful completion of the Category B training program recognized by IHO.
The final field project represents the finality of the course.
The project lasts 7 weeks including one week of exams.
The work is done in class and in the field (marina of Rimouski, St. Lawrence River).
The students have at their disposal a number of hydrographic equipment, specialized software and the CIDCO hydrographic boat.
The learning outcomes of the course are:
- Plan and organize data acquisition tasks for a hydrographic survey
- Understand hydrographic instructions and detailed specifications for acquisition, processing and quality control
- Produce different types of data and perform quality analysis to meet standards
- Provide hydrographic products from acquired data
- Write reports and survey documentation
Bordered on the north shore by the majestic St. Lawrence River on nearly 50 kilometers, Rimouski is characterized by the dual identity of the regional capital of Lower St. Lawrence and the Oceanography Capital of the province of Québec.
