Question 1 of 27070

What will the velocity and direction of the tidal current be at Port Morris, NY, at 1135 DST (ZD +4) on 13 May 1983?

🔍 Key Concepts

• Tidal current tables vs. tide height tables – make sure you’re using the right reference for Port Morris, NY • Using the Daily pages: how to interpolate current velocity and direction between listed times • Understanding Daylight Saving Time (DST) and converting to the correct reference time if needed

💭 Think About

• First, locate Port Morris in the tidal current tables and identify whether it is a primary station or a reference/subordinate station. How does that affect how you find the current at 1135? • On the correct date, find the times and strengths of the tidal currents around 1100–1200. Is 1135 exactly listed, or will you need to interpolate between two times? • Compare the resulting direction (set) and speed (drift) you obtain with the choices. Do any options clearly conflict with the pattern of flood vs. ebb shown for that part of the day?

✅ Before You Answer

• Confirm you are reading from the Tidal Current Tables, not the Tide Tables • Verify whether 1135 DST (ZD +4) needs any time correction in the tables you’re using (standard vs. daylight time) • Check that the direction is given in degrees True (°T) in the tables and matches the flood/ebb direction expected at Port Morris for that stage of the current
