Jasper Seamount is a

Jasper Seamount is an elongated volcano, with a northwest-northeast summit and several volcanic cones on the summit. The base is 4000 meters below sea level and it rises to a peak of 700 meters below sea level. A total of 15 dredge hauls from the seamount have been collected, and ocean-bottom seismometers have been placed to observe earthquake activity. In-depth studies have given scientists a detailed view of the seamount's internal structure.^[1]

The model developed by the Jasper Seamount studies closely resembles that of the

Jasper Seamount formed 11.5–10 million years ago. Base volcanics are very similar to those found at Hawaii. The flanks formed about 8.7–7.5 million years ago, and its summit 4.8–4.1 million years ago. The maintenance of a near-constant silicon dioxide ratio in all of the rocks collected is a sign of increasingly lower degrees of mantle melting. Overall Jasper Seamount rock is very similar, even in trace elements, to Hawaiian volcanics, despite Jasper's much smaller size (690 km³ or 166 cu mi versus ~3,000 km³ or 720 cu mi). These results seem to show that the Hawaiian model could be applied to other seamounts as well, and that many seamounts go through the same processes regardless of their size.^[1]
