Lab groups can work together to examine high resolution photos and data from four cores taken at various depths in this first-of-its-kind complete section of oceanic crust. This poster includes background information and five classroom activities on the back.
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.

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
This exercise set explores marine sediments using core photos and authentic datasets in an inquiry-based appr
Foraminifera allow scientists to look at the past and compare it to today’s world to see how the Earth has changed over time. Scientists gain a better understanding of the Earth by looking at the distribution of foraminifera. Liv- ing forams are like mirrors on present-day condi- tions, while fossil foraminifers provide clues to past environments and how the surface of the Earth has changed over time. There are over 4000 extant (living) foram species today,…
Sixty five million years ago, a 10 km meteorite crashed into what is now Mexico’s Yucatan Peninsula, creating a 177 km crater and causing mass extinctions across the globe. There are two kits focused on this event that challenge students to look at the evidence to make inferences about the past. General Introduction Cretaceous Impact Kit: Introduce the JOIDES Resolution research vessel and scientific ocean drilling; Demonstrate how cores and sediment records drilled…
