🔍 Key Concepts

• Tidal current tables and atlas for Pollock Rip Channel on the date in question • How to convert clock time (DST, ZD +4) to the reference time used in the current table (usually standard time or time at the reference port) • The relationship between time before/after slack water or max current and the current’s velocity and direction (flood vs ebb)

💭 Think About

• First, decide whether 1700 DST on 23 July 1983 falls closer to slack water or maximum current for that stage of tide at the east end of Pollock Rip Channel • Determine whether the current at that time should be flooding or ebbing based on the sequence shown in the current table for that location • Use the table or graph to interpolate the current speed at the exact time, not just pick the nearest listed time

✅ Before You Answer

• Verify you are using the correct station (east end of Pollock Rip Channel), not a nearby reference station • Confirm that you correctly converted 1700 DST (ZD +4) to the time used in the current table before reading values • Double-check whether the table indicates flood (+) vs ebb (-) and match that to the choice that has the correct direction and magnitude for that time
