🔍 Key Concepts

• Use the charted depth (soundings) in the area between buoys "13" and "14" near the Chesapeake Bay Bridge-Tunnel • Understand that charted depths are usually referred to Mean Lower Low Water (MLLW) unless otherwise stated • Adjust the charted depth for the actual tide height when it is lower or higher than the chart datum

💭 Think About

• What is the charted depth shown on the chart for the position midway between buoys "13" and "14"? • If the tide is -1 foot, is the actual depth of water greater or less than the charted depth? By how much? • After you adjust the charted depth for the tide, which choice is closest to your calculated depth?

✅ Before You Answer

• Confirm that you are using the correct charted sounding for the exact location in the question • Make sure you are applying the tide correction with the correct sign (subtracting for negative tide, adding for positive tide) • Compare your final adjusted value carefully to the answer choices, paying attention to units (feet vs meters)
