Morphology
Bismarck + sea
The item combines the proper name 'Bismarck' (not semantically transparent to learners) with 'sea' (a body of water), so a learner might infer a geographic sea named Bismarck but would not be able to derive that the MWE denotes a specific WWII naval battle. The event meaning (a historical battle) is not predictable from the constituent words, making it idiomatic/opaque for learners.
Etymology
Bismarck Sea gets its name from the nearby Bismarck Archipelago, a group of islands that German explorers named after the leader 'Otto von Bismarck'. That is why the name refers to the part of the Pacific north of Papua New Guinea.
