Welcome Aboard the Research Vessel Atlantis, Cruise AT40-03
Welcome the not-so-regular daily blog we're keeping aboard the R/V Atlantis. "We" are 19 members of a science and technical team contributing to a research cruise that's the prelim to drilling by the International Ocean Discovery Program (IODP). Images of seafloor topography and sub-seafloor layering we collect will enable us to choose sites to be drilled by the IODP, using the D/V JOIDES Resolution 2 to 3 years from now. That effort will recover records of Earth history that can be acquired in no other way than by putting out to sea and drilling hundreds of meters into the seafloor at key locations. We expect the sediments brought up from the depths will reveal ocean-atmosphere-biosphere interaction spanning the last 70 million years. The goal will be to improve knowledge of past climate variations and the factors that regulate the flow of deep ocean water that begins in the North Atlantic and circles the globe.
