Dr. Gledhill, Atlantic Oceanographic & Meteorological Laboratory, NOAA
A 30-min, in-depth presentation of the science of OA, including carbon cycle, chemistry of OA, aragonite saturation state, and effects on coral reefs and other marine calcifiers. Presentation is closed-captioned. Presentation will play automatically in a DVD player or from a computer.
Dr. Gledhill, Atlantic Oceanographic & Meteorological Laboratory, NOAA
Slideshow from science presentation, with presentation notes from speaker. Available as MS PowerPoint file and as a PDF with speaker notes.
OA intro and classroom demos
Dr. Lubchenco, NOAA Administrator
A 15-min presentation of NOAA administrator giving overview of OA and showing two classroom demos using dry ice and chalk (video has a 12-sec delayed start).

Ocean Acidification: The other carbon dioxide problem
NOAA Pacific Marine Environmental Laboratory
A 4-minute introduction to OA, showing potential effects of pteropods ("sea butterflies.") Video also shows animation of how OA measurements are taken in the ocean, and likely effects on marine life from increasing OA, beginning at the base of the foodweb.

A 6-minute video that links OA to specific effects on particular marine species - sea urchins - and shows how these are collected and studied. Includes animation of OA chemical equation, and shows how sea urchin larval measurements are made to study effect of future ocean conditions. Video can be used as introduction to activity "OA Virtual Lab," under Multimedia section.
