Senior technician and laboratory manager Mike Hall describes work pioneered with Nick Shackleton on the use of mass spectrometers to determine climate change from deep sea sediment cores, containing shells of foraminifera.

From glacial highs, to abyssal lows, this episode explores the many sedimentary environments and their rock forms.
This movie demonstrates how a sample of seabed sediment core can be extracted by lowering from a ship a vibrocorer to the seabed. This particular animation demonstrates GeoCorer 6000 being lowered from Ireland's Marine Institute vessel, the Celtic Explorer. This animation was funded by Titanic Belfast's Ocean Exploration Centre, and forms part of their seabed simulation display, open to the public
River Geomorphology Video created by Little River Research and Design, with funding from the Missouri Department of Natural Resources. http://serc.carleton.edu/details/files/19075.html As the clip opens you see shallow flow with uniform bedmaterial transport throughout. A small low head wier or dam is installed. This produces deep subcritical flow above the dam and critical flow over it. Below the dam we see supercritical flow. The deeper, low velocity flow above the dam cannot move the coarse bedload (Q = VA, and since A is greatly increased and Q is unchanged above the dam, V is greatly decreased) and we see deposition occur until depth is shallow enough (and A small enough) that the increase in V moved bedload again. Deposition occurs to the top of the dam. When the dam is in...

http://gallery.usgs.gov/videos/534 Geologists rely on information from deep beneath the Earth's surface to reconstruct the past. As sediments accumulate over time, they create records geologists use to understand Earth history and to predict future processes and trends. The most common way to get this information is to drill a hole in the Earth where sediments have been deposited over time. The type of drilling tool used for cores depends on how deep and how hard the sediments are. Vibracoring is one of the tools used in shallow coastal areas where sediments consist of soft sand and mud. This video podcast describes how cores are collected in shallow water from the deck of a research vessel using vibracoring. The sediments drilled are recovered in the form of a core that will contain an i...
