Question 1 of 27070

What will be the velocity of the tidal current at Port Royal, VA, at 1505 DST (ZD +4) on 4 June 1983?

🔍 Key Concepts

• Tidal current tables and stations – understanding how to use the current tables for Port Royal, VA • Time and time zones (DST vs standard time) – converting 1505 DST (ZD +4) to the time format used in the tables • Interpolation between tabulated times – estimating current velocity between listed times in the table

💭 Think About

• First, determine whether you are using a primary or a subordinate current station for Port Royal, VA and what reference data you need to apply • Convert 1505 DST (ZD +4) to the correct reference time used in the current tables; ask yourself if you need to adjust for daylight saving time • Once you find the closest times in the table around 1505, think about how the current changes between those times and how to estimate the velocity at 1505

✅ Before You Answer

• Confirm you are using the correct date and location (Port Royal, VA, 4 June 1983) in the appropriate Tidal Current Tables for that year • Double-check your time conversion: is the table in standard time, and have you properly adjusted from DST to the table’s time base? • Verify you are reading the velocity column (knots) for the correct phase of current (flood or ebb) before interpolating the value at 1505
