Other ID: S1-86
Status: Completed
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Funding Program(s):
Principal Investigator(s): Barry Irwin
Affiliate Investigator(s): John Gann, USGS-Menlo Park
Information Specialist(s): Barry Irwin
Data Type(s): Electro-Magnetic: Gravity, Location-Elevation: Navigation, Sonar: Single Beam
Scientific Purpose/Goals: Collect gravity data in the Jamaica-Cayman Islands region.
Vehicle(s):
Start Port/Location: Kingston, Jamaica
End Port/Location: Kingston, Jamaica
Start Date: 1986-10-24
End Date: 1986-11-19
Equipment Used: LaCoste-Romberg gravimeter G-179, Magnavox System 5000 integrated navigation system, 12 kHz
Information to be Derived:
Summary of Activity and Data Gathered: Gravity data were collected along 6608 km of 18 km-spaced tracklines around the north, east and west coasts of Jamaica and around the Cayman Islands. Mean line crossing statistics for the leg were generally below 1 mgal with standard deviations ranging from 1.7 to 2.2 mgals. The STARFIX system worked almost continuously allowing 24-hr. collection of data totalling as much as 320 km/day.
