Current Information screen.
The Tidal Current Information screen displays daily tidal current data
for this station on this date at the present time. The graph at the top of
the screen is an approximate view of the flood and ebb pattern for the
day, from midnight (MN), to noon (NN) to midnight (MN). The velocity
scale at the top left side of the graph changes dynamically based upon
the maximum velocity of the current for that day.
Slack water, the period of little or no current, is represented by the
Slack Water Line (SWL). The flood appears above the SWL and the ebb
appears below the SWL. You can look up tidal current data for other
dates by changing the month, day and year selection boxes.
