Coastal Mapping
New Brunswick has 5,500 km of coastal shoreline, ranging in type from salt
marshes and rolling sand dunes to steep, rocky cliffs. The coastal zone
consists of three subzones: the nearshore area is the lowermost part and is
usually submerged and less exposed to wave action; the shore area subjected
to the wave action of cyclical tides with the lower foreshore experiencing
the daily rise and fall of normal tides and with the backshore experiencing
storm surges and seasonally high tides; the coast is the area above the line
of highest tide and is affected by sea spray and occasionally during extreme
storm surges. The effects of coastal erosion can be seen province-wide in
seaside communities, infrastructures, parks, and wildlife habitats.
Objective
The Geological Surveys Branch (GSB) maintains a small but important
Coastal Studies Program. The program’s key objective is to map and monitor
erosion along the New Brunswick coast.
Activities
The GSB regularly collects information from aerial photographs and
shoreline surveys to produce a coastal erosion database. Both Government and
the private sector consult the database when implementing such activities as
dune restoration, beach nourishment, municipal land use planning, and
federal port dredging.
The branch also played a lead role in developing the
Coastal Areas
Protection Policy for New Brunswick. Among other features, the policy
designates a 30-m building setback along coastal beaches, dunes, and marshes
to protect their ecological integrity.
Current Projects
Each year the Geological Surveys Branch initiates geoscientific field
projects to serve as a basis for mineral and petroleum exploration and for
land-use planning in New Brunswick. Field projects are conducted under our
Bedrock Mapping, Surficial Mapping, Metallic Mineral Deposits, Industrial
Minerals, Hydrocarbon Resources, Geochemistry and Coastal Mapping programs.
