On 15 October 2023, you will be docking on the Southern Branch Elizabeth River, VA at the second high tide. The berth is located between NOAA reference tidal station #8638660 and reference station #8639348. What time (LST) will you be docking? Illustration D063NG D063NG.jpg
• Second high tide of the day vs first high tide – identify both on each station’s table for 15 October 2023 • How to use two nearby reference stations when your berth lies between them (interpolating/averaging times) • All times in the table are given in LST (Local Standard Time) for that date
• First, on 15 October, mark the times of the second high tide at each of the two NOAA stations shown in the illustration. Which entries in each table are those? • If your berth lies roughly midway between these two stations, how would you estimate the tide time there using the two station times? Think in terms of taking a time somewhere between them. • Compare your estimated time with the multiple‑choice answers. Which option best matches the time you calculated for the berth’s second high tide?
• Be sure you are looking at 15 October 2023, not the 14th. • Confirm you are using the second high tide for each station (there are two highs listed for that day). • Double‑check that all times you compare and calculate are in LST, as stated on both station tables.
