Open the NOAA Tides and currents map webpage. Click Massachusetts. Or use the menu on the right-hand side to select Massachusetts from the drop-down menu labeled “zoom to region.”
Use the menu to scroll down and select the southeastern coastal city of Woods Hole. Or enter Woods Hole in the “search for station” box.
Analyze the water level graph that appears. Notice that the y-axis shows the height of the tides, and the x-axis provides the time intervals. The time 00:00 is midnight and 12:00 is noon. Look at the red Water Levels data in terms of a single day (for example, from 00:00 to 00:00), and note the number of high and low tides that typically occur in Woods Hole. Use the data from the graph to complete the following table.
