What will be the velocity of the tidal current at Port Jefferson Harbor Entrance, NY, at 1600 EST (ZD +5) on 23 December 1983?

🔍 Key Concepts

• Tidal current tables for specific locations such as Port Jefferson Harbor Entrance, NY • Relationship between reference stations and subordinate stations in current tables • Using the correct time zone and date (including EST and ZD +5) when entering the tables

💭 Think About

• Identify whether Port Jefferson Harbor Entrance is listed as a reference station or a subordinate station in the Tidal Current Tables and think about what that means for how you get the current velocity • Work step‑by‑step through the current table for the correct date and time, paying attention to whether you should interpolate between hourly values or between slack and maximum • Consider how the stated time (1600 EST, ZD +5) lines up with the times of slack water and maximum flood/ebb shown for that location

✅ Before You Answer

• Confirm you are looking at the correct year and correct month/day in the current tables (December 1983) • Verify that you have correctly interpreted local time vs. ZD +5 and that no time-zone conversion is needed when using the table for that port • Double-check whether the table gives you the current directly in knots at the requested time or whether you must apply corrections from a reference station before choosing among the options
