Votes:0 Marine Geology: Research Beneath the Sea Imagine the ocean basins drained of all their water. What would the bottom topography look like? Were mountain ranges and carved canyons hidden beneath the dark waters? How old are the rocks and sediments on the ocean floors? Geologists in the early nineteenth century speculated that the ocean floors were dull expanses of mud-- featureless and flat. For centuries, naturalists also thought that the oldest rocks on Earth were on the ocean floors. They believed that the present-day ocean basins formed at the very beginning of the Earth's history and throughout time they had slowly been filling by a constant rain of sediment from the lands. Data gathered since the 1930's have enabled scientists to view the seafloor as relatively youthful and geologicall Read More Go to Site
Votes:0 Methods and Equipment Used by Marine Geologists Most of the tools and methods used to study the ocean floors have been invented and developed within the last half-century. Marine geology, in this regard, is still a relatively young science with many unexplored frontiers. Because direct observation of the seafloor is difficult and time consuming, virtually all marine research requires vessels and sophisticated oceanographic instrumentation. The USGS now uses from 12 to 15 ships of various sizes, and from these floating laboratories marine geologists deploy their instruments. The quickest and easiest method of sampling the seafloor from a ship is by coring using a long metal pipe weighted at the top. The pipe is attached to a long multipurpose cable and is allowed to "free-fall" Gr Read More Go to Site
