Question 1 of 29218

What will be the velocity of the tidal current 4.5 miles east of Smith Point, VA, at 0630 DST (ZD +4) on 6 May 1983?

🔍 Key Concepts

• Tidal current tables and atlases for Chesapeake Bay / Smith Point area • How to convert Daylight Saving Time (DST) with a given zone description (ZD +4) to the reference time used in the tables • The relationship between tidal current velocity and the stage of the tide cycle (flood, ebb, slack)

💭 Think About

• Work out what the correct reference time is for using the tidal current table: how do you adjust 0630 DST with ZD +4 to the standard time used in the tables? • Identify which station (reference or subordinate) covers the location 4.5 miles east of Smith Point, and decide whether you must apply any corrections to the predicted times and speeds. • Once you know the correct time in the tide cycle for that day, ask yourself whether the current should be near maximum, building, decreasing, or near slack at that moment, and what that implies for its likely speed.

✅ Before You Answer

• Confirm you have converted 0630 DST to the correct standard time and then to the time used in the tidal current predictions. • Verify you are looking at the correct reference/subordinate station and date (6 May 1983) in the current tables or atlas. • Double-check whether any speed or time corrections need to be applied for the specific location 4.5 miles east of Smith Point before comparing with the answer choices.
