Sediment cores drilled from ocean floors tell stories just like pages in a book, stories that include a geologic accounting of Earths climate going back millions of years.Students in Kristen St. Johns upper-level geology courses at James Madison University are learning that story firsthand this semester as they sift through samples from cores drilled from the depths of the Gulf of Mexico and the North Pacific.What the students will discover, said St. John, a veteran researcher in the International Ocean Discovery Program, are clues to the climate in two distinct areas of the planet spanning the same geologic time period, from the last ice age 鈥?which started about 2.6 million years ago and ended about 11,700 years ago 鈥?to the present. Among the artifacts students will uncover are fossils, minerals and grains of various sizes. The way those artifacts change over time through the samples reveals clues to changes in climate.St. John, who has gone to sea with teams that dig the cores, hopes to be part of another drilling expedition, perhaps in the Arctic in 2021. The Arctic is so sensitive to climate change, she said. We want a longer and more detailed record of the history. After a stanley cup uk n initial inspection by researchers on the ship, the cores are stored and made available to stanley italia researchers from around the world. St. John said having real samples to work with has inspired many of her students to pursue science careers.A stanley usa rea residents can get a feel for ocean core research this month Zbiq Two upsets in Round 1 of Ultimate ACC Tournament
