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. download MP4 (Right Click Save As)


Acid Oceans

American Natural History Museum - Science Bulletins (http://www.amnh.org/sciencebulletins/)

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.
