辛顿透过潜艇舱门左侧的舷窗望出去，发现这座350英尺高的海山上覆盖着枕状熔岩和极少的沉积物。
Peering through the porthole stationed on the port (left) side of the sub, it appears to Sinton that the 350-foot-high seamount is covered in pillow lavas with very little sediment cover.
枕状熔岩是岩浆被缓缓推积至海底时形成的。
Pillow lavas form when molten rock is pushed up onto the seafloor at a very slow rate.
看到这里大量的枕状熔岩，辛顿立刻产生一个假设：也许该区域的海山都形成自同一次火山喷发的多条岩浆流？
There are lots of pillow lavas here too, prompting Sinton to form a hypothesis: perhaps the seamounts in this region formed from the same volcanic eruption, made up of many flows?
