What will be the velocity of the tidal...

🔍 Key Concepts

• Using the Tidal Current Tables for 1983 to find data for Shoal Point, NY and its reference/subordinate relationship • Converting Daylight Saving Time (DST) to the standard time used in current tables, paying attention to ZD +4 • Reading the current diagram or table for positions (miles) along the channel from Shoal Point to determine both direction (flood/ebb) and rate (knots)

💭 Think About

• How do you correctly convert 1850 DST (ZD +4) on 9 July 1983 to the time format used in the Tidal Current Tables for that area? • Once you have the correct time, what tide stage is occurring at Shoal Point around that time—approaching flood, maximum flood, slack, or ebb? • On the current diagram or along-channel table, what does the symbol at about 6 miles south of Shoal Point show for direction and rate at that particular time relative to the nearest listed times?

✅ Before You Answer

• Be sure you have converted DST to standard time before entering the current tables (DST is usually one hour ahead of standard time). • Confirm you are using the correct reference station and date (9 July 1983) in the Tidal Current Tables, not a nearby day or different station. • Verify on the current diagram that you are reading the value at approximately 6 miles south of Shoal Point and that you correctly identify whether the arrow indicates flood (toward) or ebb (away from) the reference direction.
