🔍 Key Concepts

• Using the Tidal Current Tables and/or current diagrams for the specific year and area (Southwest Ledge) • Converting DST (Daylight Saving Time) to standard time and understanding Zone Description (ZD +4) • Applying time and velocity differences between a reference station and a subordinate/current diagram location

💭 Think About

• How do you convert 2330 DST (ZD +4) to the standard time used in the current tables before you look anything up? What exact clock time should you enter the table with? • Once you are on 7 September 1983 in the correct table/diagram, are you reading from a reference station and then applying corrections, or from a specific current diagram for the position 2 miles west of Southwest Ledge? • At the chosen time, is the current building toward maximum, at maximum, or decreasing? How does that affect the velocity you select among the choices given?

✅ Before You Answer

• Be sure you are using the correct date and tide cycle (flood vs. ebb) for 7 September 1983 at the converted local standard time. • Verify that you applied any time differences and speed factors for the subordinate location (2 miles west of Southwest Ledge) correctly. • Double‑check that you did not confuse DST adjustment with the zone description (ZD +4); they are two separate steps.
