What will be the velocity and direction of the tidal current at Mobile River Entrance, AL, at 0915 CDT (ZD +5) on 13 May 1983?

🔍 Key Concepts

• Tidal Current Tables for 1983 and how subordinate stations relate to a reference station • How to convert local time (CDT, ZD +5) to the standard time used in the tables • How to read velocity and direction from a current table or current graph at a given time

💭 Think About

• First, what reference station in the Tidal Current Tables controls Mobile River Entrance, AL, and what corrections (time and velocity) apply to that subordinate station? • Once you apply the time correction to 0915 CDT, where does that adjusted time fall in the tidal cycle (near slack water, max flood, or max ebb)? • Based on the table/graph for that phase of the current, what are the closest listed values for rate (knots) and set (direction, degrees True) around that time?

✅ Before You Answer

• Confirm you have converted 0915 CDT correctly to the time base used in the Tidal Current Tables for the reference station • Make sure you apply both the time corrections and the velocity factor for Mobile River Entrance, not just one of them • Verify that the direction (°T) you select corresponds to the correct phase (flood vs. ebb) of the current at that time
