The Ship Tracker Screen will appear, you will see a map of Buzzards Bay with little red dots around it. These dots are the ships location for a given day. Beneath the map are links to data you need to record. For example: the tides, temperature, and visibility readings.
Beneath those links you will see the name of the ship and its current position (longitude & latitude) Using the new position plot the ships new position. Draw a line between the two dots. This is the new distance.
Measure the distance between the previous location and the current location (using the map key) to get the distance traveled for that time period. Using the distance and time period you can calculate the average velocity for the day using the formula Velocity= distance/time.
Alternatively, you can calculate the distance using this online calculator
Next return to the blog entry and perform the activities suggested.
