The two 30cm replicas of 310-20A-22R-2 display coral sandstone and massive coral (Porites) in growth position with interbedded microbiolites (organosedimentary deposits). Cavities are filled with Halimeda (calcareous algae) segments, gastropods, bivalves and microbiolites.
The sediment cored at Saanich Inlet off Vancouver Island, British Columbia contains evidence of catastrophic flooding events – called Jokulhlaups (Icelandic, pronounced o-kul-loop) that took place at the end of the Pleistocene and Early Holocene. This is when the Ice Age came to an end and increasing global temperatures caused glacial dams to form large lakes that eventually drained dramatically when the dams melted and broke. This core shows an abrupt 30cm layer of silty…
This core shows two time periods when a warming climate initiated a rapid release of carbon resulting in extreme ocean acidification.
This model shows seasonal layers (laminae) composed of different diatoms species that were deposited during the late Holocene and provides evidence for the changing climate and glacial retreat that took place in the region after the last ice age. This core section also contains a drop stone.
Expedition 303 drilled cores from the North Atlantic that helped build a timeline of climate change over the last several million years of Earth’s history. This data has provided invaluable insight into the most recent “Ice Ages” or glacial periods of cold climate with a lot of land and sea ice, and warmer periods with little to no ice called interglacial periods.
General Introduction Cretaceous Impact Kit: Introduce the JOIDES Resolution research vessel and scientific ocean drilling Demonstrate how cores and sediment records drilled from the ocean floor can be used to make inferences about past events Present different careers associated with conducting science on the ship. Using the Cretaceous Impact Event to Teach Science Process Challenges students to make core observations and generate questions to obtain information that helps them make inferences about past events. Introduces…
The Glacial Interglacial Core Model contains evidence of a shift from an interglacial to a glacial period approximately 0.9 million years ago. This core can be loaned out for your educational needs.
Episode 1: Tales of the Resolution! The reader is introduced to the ship and its history of discovery. This graphic novel takes place just before the JR was about to undergo a major re-fitting after two decades of scientific ocean drilling. Authored and designed by Carl Brenner from the Borehole Research Group. More graphic novels can be found at http://www.ldeo.columbia.edu/BRG/outreach/media/tales/index.html
This set of investigations focuses on the use of sedimentary facies (lithologies interpreted to record particular depositional environments) to interpret paleoenvironmental and paleoclimatic changes in Neogene sediment cores from the Antarctic margin. In Part 12.1, you wil
