🔍 Key Concepts

• Using NOAA tide tables for a reference station and a subordinate station • Identifying the second high tide for a specific date at each station • Estimating a time for a location between two tide stations by interpolation/averaging

💭 Think About

• First, for 5 October 2023, what are the listed times of the second high tide at the reference station and at the subordinate station shown in the figure? • How far apart in minutes are those two second‑high‑tide times, and where would a berth located between the two stations likely fall within that interval? • Are all the times in the figure already given in Local Standard Time (LST), or do you need any additional time correction?

✅ Before You Answer

• Be sure you are looking at 5 October 2023, not 4 October • Confirm you are using the second high tide of the day (after the morning high), not the first • Double‑check that you choose an answer that falls between the two second‑high‑tide times shown for the reference and subordinate stations
