Swimming Jellyfish May Influence Global Climate
October 31, 2011
Swimming jellyfish and other marine animals help mix warm and cold water in the oceans and, by increasing the rate at which heat can travel through the ocean, may influence global climate. The controversial idea was first proposed by researchers out of the California Technical Institute in 2009, but new information may help the scientists support their claim.
Dr. Kakani Katija Young, who worked on the original paper, and her team at the Woods Hole Oceanographic Institute published an article in the Journal of Visualized Experiments (JoVE) this month, explaining how to use a Self-Contained Underwater Velocimetry Apparatus (SCUVA).
The apparatus is used underwater at night to light up animals, like jellyfish, swimming in the ocean. It also illuminates the particles around the animals, showing how the animals move the water around them when they swim.
The combined effect of all ocean life swimming in concert may have an impact on ocean climate on the same magnitude as wind. Though the apparatus was used in the original research, Dr. Young is publishing the experimental technique now in the hopes that other scientists will use it to gather more evidence supporting her theory.
"We felt that it is such a powerful tool that isn't being used in the community," she said. "And I feel that people learn so much better from visual material than they do from just reading text."
JoVE is the first peer reviewed video journal indexed in PubMed and MEDLINE, so Dr. Young's technique is demonstrated in video format, rather than simply in text.
About JoVE, The Journal of Visualized Experiments:
JoVE, the Journal of Visualized Experiments, is the first and only PubMed/MEDLINE-indexed, peer-reviewed journal devoted to publishing scientific research in a video format. Using an international network of videographers, JoVE films and edits videos of researchers performing new experimental techniques at top universities, allowing students and scientists to learn them much more quickly. As of June 2013, JoVE has published video-protocols from an international community of more than 8,000 authors in the fields of biology, medicine, chemistry, and physics.
