IOC/OTGA - RTC KMFRI: Fundamentals of Ocean Floor Mapping

Résumé

The course provides an overview of the ocean's seafloor, its features, properties and tools used to describe the seafloor. The course shall contribute to the goals of the UN Decade of Ocean Science for Sustainable Development, specifically the three societal outcomes that are critical in ocean mapping: a) a healthy and resilient ocean b; a predicted ocean and c) a transparent and accessible ocean.

Learning Outcomes

After the course participants will have the knowledge, skills and experience to be able to:

• understand the fundamentals of bathymetric survey planning and execution (including fixed geodetic points vs portable GPS)
• have skills in processing of bathymetric data and generation of bathymetric maps using CARIS, QGIS
• Understand the difference between single-beam and multi-beam data
• Recognize key bathymetric seafloor geomorphology and water column acoustics
• Generate satellite derived bathymetry for coastal shallow areas
• Be aware of the seabed 2020 seafloor mapping initiatives and obligations
• be aware of the UNCLOS and governance of the seabed
