1·Microscopic organisms settle to the seafloor and accumulate in marine mud.
微生物在海底定居并在海泥中积聚。
2·Data from diverse sources, including geochemical evidence preserved in seafloor sediments, indicate that the Late Cretaceous climate was very mild.
来自不同来源的数据，包括保存在海底沉积物中的地球化学证据，都表明晚白垩世的气候非常温和。
3·Another task for the Glomar Challenger's scientists was to try to determine the origin of the domelike masses buried deep beneath the Mediterranean seafloor.
格洛玛挑战者号的科学家们的另一项任务是尝试确定地中海海底之下深埋的圆顶状物质的起源。
4·Data from diverse sources, including geochemical evidence preserved in seafloor sediments, indicate that the Late Cretaceous climate was milder than today's.
来自不同来源的数据，包括存留在海底沉积物中的地球化学依据，表明晚白垩纪的气候比如今的要温和。
5·They therefore permit the reconstruction of the process of seafloor spreading, and consequently of the geography of continents and of ocean basins in the past.
因此，它们可以重现海底扩张的过程，以及大陆和大洋盆地过去的地理位置发展过程。
