On 27 April 1983, at 1105 DST (ZD +4), what will be the predicted height of tide at Falkner Island, CT?

🔍 Key Concepts

• Tide prediction table for the reference port and differences for the subordinate station • Converting between zone description (ZD) time and the time standard used in the tide tables • Using linear interpolation between hourly heights if the exact time isn’t listed

💭 Think About

• First, decide whether Falkner Island is a reference station or a subordinate station and determine which main station’s data you must start from. • Check the standard time used in the tide tables and adjust the given 1105 DST (ZD +4) to that time before entering the tables. • Locate the two surrounding times in the table and think about how to estimate the height at 5 minutes past the hour using interpolation.

✅ Before You Answer

• Verify the time conversion from daylight saving time (DST) to the tide table’s standard time before looking up any heights. • Confirm you have applied the correct time and height differences for Falkner Island relative to its reference station. • Double-check your interpolation steps between the two nearest tabulated times to see if the final height is reasonable compared to the surrounding values.
