🔍 Key Concepts

• Tidal Current Tables for 1983 and how reference vs. subordinate stations are used • How to interpret the daily current table for a specific date (18 November 1983) and station (Marcus Hook, PA) • How the current velocity changes between slack water and maximum flood/ebb, and how to interpolate between listed values

💭 Think About

• First, locate the correct day and station, then identify the times and velocities just before and after the point where the current would be 0.5 knot • Decide whether the current is increasing or decreasing around 1200, and if it is flood or ebb at that time • Use proportional (linear) interpolation between two listed times and velocities to estimate the time when the current would be exactly 0.5 knot

✅ Before You Answer

• Confirm you are using the correct year (1983), date (18 November), and station (Marcus Hook, PA) in the Tidal Current Tables • Verify whether Marcus Hook is a reference station or subordinate station, and apply any required time and velocity corrections if it’s subordinate • Double-check the two surrounding current predictions (time and velocity on either side of 0.5 knot) and that your interpolation keeps times in EST with ZD +5
