On 14 October 2023, you will be docking on the Southern Branch Elizabeth River, VA at the first 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
• Using reference tidal stations when your berth lies between two NOAA stations • Identifying the first high tide on the correct date at each station • Estimating the time at an in‑between location by interpolating/averaging the two station times
• For 14 October, what is the time of the first high tide at station #8638660, and what is the time of the first high tide at station #8639348? • If your berth lies between these two stations on the same river branch, should its high water time be closer to one station, the other, or somewhere between them? Why? • Once you estimate the intermediate time, which answer choice is closest to that value?
• Make sure you are using 14 October 2023 data, not 15 October. • Confirm you are picking the first high tide of the day, not a low tide or the second high tide. • After you estimate the in‑between time from the two stations, double‑check which option is numerically nearest to your calculated time.
