🔍 Key Concepts

• Tide tables for 1983 and how to use them for a specific date and time • Difference between a reference station and a subordinate station in tide predictions • How to apply time and height corrections from the reference station to the subordinate station

💭 Think About

• First, identify the reference station used for Three Mile Harbor Entrance in Gardiners Bay, and find the predicted high and low waters around 0700 (ZD +5) on 14 Nov 1983 at that reference station. • Then, determine where 0700 falls in relation to the surrounding high and low waters (flood or ebb) so you know whether to interpolate on the rising or falling tide. • Use the tide curve or table to interpolate the height of tide at the exact time, after applying any required time and height corrections for the subordinate station.

✅ Before You Answer

• Confirm you are using the correct reference station and the correct page/year (1983) of the tide tables. • Make sure you convert and apply the time corrections properly for Three Mile Harbor Entrance relative to the reference station, including the time zone (ZD +5). • Double-check that you are interpolating between the correct pair of high/low waters and applying the proper height correction factor for that part of the tidal cycle.
