Question

Quizplus · Accepted Answer

Chronometer, specifically a marine chronometer, is used to determine longitude by measuring the time difference between noon at the location and noon at a reference point (usually Greenwich, England) to calculate the longitude in degrees. A pendulum clock is used for determining local time but is not accurate enough for precise longitude calculations. Echo sounders and remote operated vehicles have no relevance in determining longitude.
