Capturing a seal to study

Dear Friend,

Sometimes no one can work outdoors because of a Herbie—a dangerous windstorm blowing loose snow. (The name comes from “hurricane-blizzard.”) In good weather some of the scientists may search for a Weddell seal to study. Here’s one found near Tent Island. It will be carried by vehicle back to the “wet lab,” where the scientists will gently and carefully attach instruments to its body. (The instruments come off after a few days.) Then the scientists will let the seal go beneath the ice.

Marine mammals enjoy special protection in the United States. Research on marine mammals (including photography) within U.S. jurisdictions or when based at a U.S. institution requires a permit under the U.S. Marine Mammal Protection Act. Bob Marstall, who took this photo, is listed on Dr. Randall Davis's permit, which is Marine Mammal Permit #821-1588-01.

Your friend,

Bob
