🔍 Key Concepts

• General ocean circulation vs. local tidal currents • What information is typically found in a Pilot Chart • Typical contents of Coast Pilot, Climatological Atlas, and Current Tables

💭 Think About

• Ask yourself: which publication gives a large-area, big-picture view of winds, currents, and weather patterns over an entire ocean? • Which of these choices is usually used for day‑to‑day predictions of current at a specific location and time, rather than long‑term averages? • Which is primarily a coastal aid with harbor, channel, and coastal information, not broad ocean circulation?

✅ Before You Answer

• Verify which option shows average currents and prevailing conditions over large ocean areas. • Check which publication is used mainly for local predictions of tidal currents for specific dates and times. • Confirm which reference is focused on coastal navigation information such as regulations, port facilities, and local details, not basin‑wide current patterns.
