FIELDS Methods
- Bathymetric
Surveys
- Bathymetry is the measurement of depths of water bodies,
providing bottom topography. Transducers mounted on a survey boat
measure the time it takes for an acoustic pulse to travel to the
bottom and back. Simultaneously, GPS records location, gauges record
water level fluctuations, and sound velocity measurements are taken
(or compensated for). All this data is integrated using time-tags.
- Data Analysis
- The FIELDS Team and the FIELDS Tools can provide a range
of data analysis services. These services are broadly defined as
sample design, database query, and data and decision analysis
- Geography Information
System (GIS)
- A Geographic Information System (GIS) is a computer-based
system designed to collect, store, integrate, manipulate, analyze
& display data in a spatially referenced environment
- Global Positioning
System (GPS)
- The Global Positioning System (GPS) is a satellite-based
navigation system made up of a network of approximately 24 satellites
placed into orbit by the U.S. Department of Defense.
