Question 84Navigation General

The correct answer is D) MERWARN. The code word "MERWARN" is used to notify mariners of any hazardous areas due to the fallout of a nuclear explosive. This is in accordance with the Marine Environmental Response (MER) plan, which outlines the procedures and protocols for responding to and communicating about nuclear or radiological incidents that may affect the maritime environment. The other answer choices are incorrect because they do not represent the standard code word used for this type of notification. "FALLWARN," "FALLOUT," and "NUCLEAR" are not the specific code words defined in the MER plan for communicating information about nuclear fallout to the maritime community.
