Seventy-three loggerhead sea turtles hatched at an Alabama beach Wednesday and entered the waters into the northern Gulf of Mexico.

For the past two months, scientists have deemed the Gulf of Mexico unsafe for sea turtle hatchlings due to BP’s catastrophic oil spill.  They have transported 28,000 eggs from Alabama and Panhandle beaches to Florida’s Atlantic coast.  After incubation at a Kennedy Space Center facility, the hatchlings were released into the Atlantic at Merritt Island National Wildlife Refuge.

However, after further examination of the Gulf waters, scientists have determined the northern Gulf of Mexico is now safe for sea turtles.

According to Dianne Ingram of the U.S. Fish & Wildlife Service, “It was a good decision based on the best information we can get. It was more risky to ship them to Florida than it was to let them go straight into the water.”

The group of loggerhead hatchlings that entered the Gulf Wednesday was the first batch in Alabama allowed to enter their native waters.

Last week, we wrote about Crittercam, an exhibit presented by the Museum of Science, Boston and National Geographic.  Yesterday, we had the opportunity to visit the exhibit in person.

Crittercam provides a fascinating look into the behavior of several kinds of animals including penguins, seals, sea turtles, sharks, lions, bears, and more.  Using cameras attached to various animals, scientists were able to gather data about hunting techniques, social norms, and daily activity that had previously eluded them.  The exhibit provides video footage captured by the animals along with explanatory text and a few fun facts about the animals discussed.

But the exhibit also delves into the technology and methodology of Crittercam.  There are models of animals showing how the special cameras were attached and adapted to a particular animal’s lifestyle.

For example, the soft, flexible shells of leatherback sea turtles did not allow the camera to be attached by an adhesive. Instead, a suction cup was applied to the central plate of the turtle’s shell.

Using videos, photos, life-size models, and computer kiosks, the exhibit appeals to an audience of all ages and interests. So if you live in or plan to visit the Boston area, be sure to visit Crittercam at the Museum of Science, which runs through August 30.

During our visit, the museum made an exciting announcement (delivered by an owl) about a very special international exhibition that will open in Boston on October 25, 2009 called Harry Potter: The Exhibition.

Fans of Harry Potter will soon get the chance to immerse themselves in the wizarding world.  Artifacts and costumes from the latest Harry Potter films will be displayed in a 10,000-sq. ft. space.
