What will be the velocity of the tidal...

🔍 Key Concepts

• Use the Tidal Current Tables for the correct year and area (New York Harbor / East River vicinity) • Identify whether the location 0.2 mile SSW of Clason Point is a reference station or a subordinate (secondary) station • Apply time and velocity corrections from the reference station to the subordinate station at the given time and date

💭 Think About

• First, find the reference station used for Clason Point in the Tidal Current Tables, then note its predicted current at 1125 on 17 April 1983 • Determine the nearest listed time in the tables and whether 1125 requires interpolation between two tabulated times • Apply the appropriate percentage or knot corrections given in the table for that subordinate station to the reference station’s velocity

✅ Before You Answer

• Confirm you are using the correct day, month, and year in the current tables (1983, not a different year) • Verify whether the table for that subordinate station lists corrections as ratios/percentages or as add/subtract knots to the reference station’s velocity • Double-check whether you must interpolate both time and velocity or just velocity before matching to the closest multiple-choice value
