A bearing is the angle between the line joining the two points of interest and the line from one of the points to the north, such as a ship's course or a compass reading to a landmark. On nautical charts, the top of the chart is always true north , rather than magnetic north , towards which a compass points.
A sounding line can still be found on many vessels as a backup to electronic depth sounding in the event of malfunction. GPS has largely replaced the sextant and chronometer to establish one's position at sea, but many mariners still carry a sextant and chronometer as a backup.

More and more water accumulates on ...
A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location. [1] The term above sea level generally refers to the height above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today.
Black seadevils can live up to 15,000 feet under the ocean surface, with humpback anglerfish specifically known to live as deep as roughly 6,500 feet under the sea, according to the researchers.
Instruments used to plot a course on a nautical chart. In navigation, the course of a watercraft or aircraft is the cardinal direction in which the craft is to be steered.The course is to be distinguished from the heading, which is the direction where the watercraft's bow or the aircraft's nose is pointed.
