Drink coffee and water. Drinking both coffee and water can help reduce alcohol breath. Water replenishes the hydration you lost drinking and promotes salivation, which can lessen alcohol breath. Coffee has a strong smell on its own, which can cover up the foul smell of booze.
By tagging the whales, we get a position from GPS and we can track them and create computer simulations of the behavior of the exact movement of the whales. What weâre looking at here is the movement of a whale underwater, derived from the tag data, but then displayed using a software called TrackPlot.
Given a starting point from dead reckoning (calculations based on speed, time, and direction) or a sextant reading, you would track the boat's direction (with a compass) and speed (with a log) to continue to know the boat's position. Now, however, most mariners use a marine GPS chartplotter to navigate.ome handheld GPS units also are plotters, if they show the position of the boat on a chart. A GPS unit that provides the position only in longitude and latitude is not considered a plotter. For all types of plotters, the general principles are the same: 1  The screen shows a nautical chart.
