A Virtual Marine Sediment Core Collection

Overview: A primary objective of marine science classes is to learn the location and formation of ocean sediment types. Nearly 50 years of scientific ocean drilling has produced a tremendous scientific collection of cores from the global ocean floor. In addition, there are large online databases and related publications that have a wealth of associated information to supplement physical cores. Here we created a virtual marine core collection that provides exemplars of the primary ocean sediment lithologies, along with links to expedition reports and datasets, and tips for making requests for real core samples to use in education.

This Google Earth Virtual Marine Sediment Core Collection shows core locations and how their location influenced their sediment type. Each exemplar core has information on the sediment type, with links to images, core descriptions, maps, geologic interpretations, and other data. The virtual core collection provides comprehensive, efficient access to information condensed down to essentials for learning. An interactive animation shows core photos emerging from the ocean floor, illustrating where the sediment cores originate. This is an educational resource for those wanting interactive teaching options for basic Earth and ocean science. It can be used alone or with another Google Earth resource on marine sediments: a virtual map of >2500 marine sites showing the distribution of primary seafloor sediment types (http://geode.net/exploring-marine-sediments-using-google-earth/).

Audience: Intended for use in undergraduate Oceanography, Marine Geology, Paleoceanography, and Sedimentology courses.

Request Marine Sediment Samples: While this virtual core collection makes learning about ocean sediment more accessible, educators can also request real ocean sediment samples for use in teaching. This is done using the same system that scientists use to request research samples: http://iodp.tamu.edu/curation/samples.html. Click on the green Sample and Data Request button. This will take you to a new link where you can set up an account and submit your request. Requests can be made for samples (e.g, 10 to 20 cc) that represent each of the primary sediment types in the ocean from these (or similar) cores. In addition, representative smear slides (i.e., like thin sections but of unconsolidated sediment instead of rock) can be requested. For tips on making sample requests for education purposes contact Kristen St. John (stjohnke@jmu.edu). See also: http://iodp.tamu.edu/curation/gcr/index.html

References and Acknowledgements: Data used in this educational resource comes from the Ocean Drilling Program (ODP, http://www-odp.tamu.edu/), the International Ocean Discovery Program (IODP, http://www.iodp.org/). The IODP Google Earth Bore Hole Map https://www.iodp.org/borehole-map was used as a starting point for data access, and a model for organizing access to scientific reports and data. The resource was modeled after a new virtual marine sediment map of the ocean floor http://geode.net/exploring-marine-sediments-using-google-earth/ that was developed as part of the GEODE project. Information on core sites and lithologies were derived from the scientific reports associated with each research expedition. A cross section generator program http://geode.net/resources/mapping-tools/ was adapted to use to elevate photos of cores rising up from the seafloor. Development of this educational resource was supported by the NSF-funded GEODE project.

Not all basalts are created equal

Compare these two basalts. One is an example of a basalt flow, the other of a pillow basalt. Pillow basalts erupt underwater and cool instantaneously around their margins, while basalt flows cool more gradually, and fractures may break the flow up into discrete cooling columns.

3D model of Outcrop A

3D model of Sample B

Which basalt formed as part of a flow? (A or B)

Which basalt is more likely to be associated with oceanic sediments? (A or B)

Now take a look at this outcrop (which we can call outcrop C) from Washington state’s Columbia River flood basalt province.

3D model of Outcrop C:

What characteristics does it display?

How would you interpret the story of its formation?

Welcome to the Grand Tour of the Terrestrial Planets

From here you can download tiny ‘leader’ KML files linking to our four tours. A paper describing them has been submitted to the Journal of Geoscience Education. It is currently accepted subject to revision. We will upload it here along with supplemental documents including lesson plans and pre-/post tests as soon as we hear whether our revision manuscript has been accepted.

Virtual Exploration

Two of GEODE’s GigaPan team (Ron Schott and Callan Bentley) contributed GigaPan imagery to the online “virtual exploration” map for PBS NOVA’s new “Making North America” series:
This map allows users to explore key sites in the geology of the North American continent through video and GigaPans.
The three-part series is hosted by Kirk Johnson, the Sant Director of the Smithsonian Institution’s National Museum of Natural History, in Washington, DC.
