Ice concentration is measured in tenths. What concentration range of ice corresponds to "Open Pack"?
AI Explanation
The correct answer is D) 4 - 6 tenths.
According to the standard ice concentration scale used in nautical operations, "Open Pack" ice refers to a concentration range of 4 to 6 tenths. This means that the ice coverage in the area is between 40% and 60% of the total surface area.
The other answer choices are incorrect because: A) 1 - 3 tenths corresponds to "Loose Pack" ice, C) less than 1 tenth corresponds to "Open Water", and B) 7 - 8 tenths corresponds to "Consolidated Pack" ice.
