🔍 Key Concepts

• NOAA chart symbology for soundings and depth contours in unshaded (white) water • Difference between soundings (individual depth numbers) and contours (lines connecting equal depth) • How offshore depth units are commonly expressed on U.S. charts (feet vs fathoms)

💭 Think About

• Ask yourself: in deeper, offshore unshaded water, are mariners usually thinking in feet or in fathoms when planning routes? • Consider what a contour interval is meant to show: does it stay fixed everywhere, or is it tied to a standard unit used offshore? • Look at how near‑shore (shaded) depth information differs from offshore (unshaded) depth information on typical U.S. nautical charts.

✅ Before You Answer

• Verify what unit of measure is normally used for offshore depth contours on standard U.S. charts (feet or fathoms). • Check whether the interval is described as a fixed number of feet everywhere, or a fixed number of fathoms. • Confirm that the option you choose matches how depths are actually labeled on most NOAA charts in the white (unshaded) offshore areas.
