CHS Dartmouth NS+CHS St. John’s NL=CHS Atlantic

• CHS Dartmouth is responsible for chart portfolio for NS, NB, PEI and NL.

• CHS Newfoundland office is part of the Science Branch, DFO Newfoundland and Labrador but operationally reports to CHS Dartmouth.

• CHS Newfoundland office inputs into CHS Dartmouth office management and planning.

• Data management including cataloguing, source data archival, the Bathymetric Database and the Hydrographic Product Database are maintained by CHS Dartmouth. Newfoundland office accesses these resources via network.

• CHS Newfoundland office focuses mainly on data collection and chart production utilizing the above resources at CHS Dartmouth to manage the data.

• CHS’s Atlantic portfolio consists of 291 charts with 170 in the province of Newfoundland and Labrador.

• Our mandate is nautical publications-charting. Data collection-Ocean Mapping is a costly necessity.

• CCGS Fredrick J. Creed (67 ft Catamaran with an EM1002 and EM 2040 multibeam sounder and 4 hydrographers)

• Three 32 ft survey launches with EM 3002 or EM2040 dual head Multibeam sounders

• One 34ft survey launch with a EM 710 multibeam sounder (NL office)

• Two 26ft survey launches with an R2 sonic or EM3002 multibeam sounders

Survey deficiencies

It’s a big Ocean…What we need to survey

Navigationally Significant Deficient for NL and Lab=58,000 km^2


Survey deficiencies

Voisey Bay area, survey deficent


Most cost effective survey methodologies





Field Surveys 2014

• Approach is to fix areas, rescheme-reformat, look at deficiencies and survey by the most cost effective methodologies


• Goose Bay-Groswater Bay survey, about 140nm end to end

• Data from collaboration with Memorial and UNB in 2012 and 2013

• CHS shore party in 2014, all survey data collected using PPK and

reduced to chart datum using our Continuous Vertical Datum

model.


Field Surveys 2014

PPK GPS Station Survey Launches, Goose Bay


Future Plans 2015

World Class Tanker Safety System (WCTSS) Ports (Phase 2)

• Government of Canada Economic Action Plan 2012 … Transport Canada lead initiative to create a world class tanker safety system.

• Three ports in the province identified for phase two; St John’s, Come by Chance, and Goose Bay
