Target class: submerged landform Context triple: [North American continental margin, instanceOf, submerged landform]
-
A.
submarine geological feature
A submarine geological feature is a naturally occurring structure or landform on the ocean floor, such as seamounts, trenches, ridges, or hydrothermal vents, formed by geological processes beneath the sea.
-
B.
submerged continental margin
chosen
A submerged continental margin is the gently sloping, geologically passive underwater extension of a continent, typically consisting of a continental shelf, slope, and rise that transition into the deep ocean basin.
-
C.
seamount
A seamount is an underwater mountain formed by volcanic activity that rises from the ocean floor but does not reach the water's surface.
-
D.
submarine basin
A submarine basin is a large, low-lying depression on the ocean floor that collects sediments and is often bounded by higher seafloor features such as ridges or continental margins.
-
E.
former island
A former island is a landform that was once completely surrounded by water but has since become connected to a larger landmass or lost its insular status due to natural or human-induced changes.
- F. None of above.

The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
