What should NOT be used as an indicator that ice may be nearby?
AI Explanation
The correct answer is D) A dark appearance of the sky.
A dark appearance of the sky should not be used as an indicator that ice may be nearby. This is because a dark sky appearance is not directly related to the presence of ice. The other answer choices, such as a yellowish glare in the sky, a drop in seawater temperature, or the presence of certain wildlife, are more reliable indicators that ice may be present in the area. Knowing the proper signs of approaching ice is crucial for Coast Guard captains to navigate safely and avoid hazardous conditions.
