🔍 Key Concepts

• How different hazards are shown on NOAA charts, especially rocky areas, shoals, and reefs • The difference between contour lines (joining equal depths) and symbol/line styles that mark dangers like breakers or kelp • How dotted vs solid lines are typically used around small islands and reefs on U.S. charts

💭 Think About

• Look at how Goose Island and Kimberly Reef are outlined: does the dotted line follow a specific depth value, or does it seem to enclose a hazardous area? • Compare nearby regular depth contours on the chart with the dotted outline—do they look the same type of line or different in style and purpose? • Ask yourself what feature would usually be wrapped closely around a small island or reef to warn mariners about what happens when seas are running.

✅ Before You Answer

• Compare the chart’s legend or marginal notes for the meaning of different line styles (dotted, dashed, solid) • Identify at least one true depth contour line elsewhere on the chart and see how its symbol differs from the dotted line in the question area • Confirm whether the area inside the dotted lines would be expected to have breaking seas, irregular soundings, or just a specific depth level.
