Daily RVGS Operations

In January 2021, as part of ESCI896.02 Applied Physical Oceanography for Hydrographic Surveyors, five days were allocated in the J-Term to operating the RV Gulf Surveyor in the outer harbour and inner shelf. The aim was to provide a complementary practical laboratory to allow the students to simultaneously investigate two aspects:

The labs took place on five spaced weekdays from ~ 10 am to 2pm local time. By spacing the outings over the 3 week period of the J-Term (January), the circulation was investigated at multiple phases of the tide and as the tide varied from neaps to springs.

Being January, the circulation was expected to reflect the seasonal conditions (low/no river flow, colder are than ocean temperatures).

Each of those ~4 hour tide windows  examined a slightly different phase of the tide:
