Which navigational outcome was critically improved by the invention of the marine chronometer?

💡 Explanation

When a marine chronometer keeps extremely accurate time, the longitude can be precisely determined because it is calculated by comparing local time (sundial) to time at a known fixed location(Greenwich). Therefore determination of longitude resulted, rather than bearing, depth or weather which are determined by different instruments and measurements.
