Q

Where can information about the direction and velocity of rotary tidal currents be found?

🔍 Key Concepts

• Difference between tides (vertical rise and fall of water) and tidal currents (horizontal movement of water) • Which publications give current direction and velocity versus which give only height of tide • Which U.S. government publications are officially used for current predictions

💭 Think About

• First, sort the choices into those that deal mainly with tides (heights) and those that deal with currents (set and drift). • Ask yourself: which publication is designed specifically to tell you how fast and in what direction the water is flowing at various times? • Consider which of these is an official hydrographic/NOAA product focused on currents rather than on astronomical data or general guidance.

✅ Before You Answer

• Identify which book is dedicated to currents, not just water level changes. • Check which publication gives set (direction) and drift (speed) for various locations and times. • Eliminate any options that are primarily about tide heights, celestial navigation, or general seamanship advice.
