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.
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…
Faulted claystone, silty claystone, sandy silty claystone from late Pleistocene subunit IIC recovered from hole B at Site 863. This site is located at the base of the trench slope of the Chile Trench where the Chile Ridge is being subducted. One of the objectives of drilling at this site was to identify the structural fabrics and deformation caused by rift subduction.
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
