🔍 Key Concepts

• Reference Stations vs. Subordinate Stations in the tide tables • Using the Daylight Saving / Time Zone (ZD +5) correctly when entering the tables • Applying differences for times and heights from the reference station to Augusta, ME

💭 Think About

• What is the reference station for Augusta, ME in the 1983 tide tables, and what are the high and low water times and heights there on 8 March? • Once you have the reference station data, how do you adjust the times and heights to get the tide at Augusta using the listed differences? • At 2045 local time, is the tide rising or falling, and between which two tidal events (high/low waters) does that time fall?

✅ Before You Answer

• Confirm you are using the correct date, time, and time zone (watch time vs. ZD +5) before entering the tables • Verify that you applied the correct time and height differences for Augusta, ME (not another nearby port) • Double-check your interpolation between the surrounding high/low waters to find the tide height at 2045, and that the final height is reasonable compared to the two bounding heights
