Numerous sea turtles have been released back to the sea these past weeks after months of rehab in parts of the United States including California, Pittsburgh, and Florida.

On June 15, 13 fully rehabilitated patients from the Karen Beasley Sea Turtle Rescue and Rehabilitation Center were released, and while it's common for such events to be one of the public's vacation highlights, a surprising crowd of at least 1,000 arrived for the release, notes Top Sail Advertiser.

The group of sea turtles included four large loggerheads as well as little greens. Volunteers took a lengthy trek through the sand while carrying the turtles along rope barriers as the audience waved their goodbyes.

In the Assateague Island National Seashore, two green sea turtles also made their return to the ocean on June 16, which also marks World Sea Turtle Day, according to Bay Weekly. The turtles, whose names are Hardhead and Beachcomber, came to the National Aquarium in November 2015. Hardhead was found and rescued off the coast of Delaware unable to swim. The turtle had low body temperature, broken ribs and a torn lung. He received long-term rehabilitation.

As for Beachcomber, the turtle was found stranded along the coast of Cape Cod with a rare blood infection as well as kidney problems.

"The triumph of returning a healthy animal to the wild is the reason we have such a devoted Animal Rescue team," said Aquarium Rescue program manager Jennifer Dittmar of the releases. "The program is successful today with the help of our staff, volunteers and the good Samaritans who call in tips."

The National Aquarium has been making successful rescues and rehabs since 1991, with more than 160 animals returned to their natural habitats along the Maryland coastline.

There were also ten rehabbed Kemp's Ridley sea turtles released from the animal rescue programs at the Pittsburgh Zoo, the PPG Aquarium, and National Marine Life Center. The turtles were found washed up on beaches on Cape Cod beaches this winter.

Meanwhile, the latest set of releases took place on Wednesday at Round Island Oceanfront Park in Vero Beach.

According to Treasure Coast Newspapers, the turtles are now back in the Atlantic Ocean after months of rehab at the Brevard Zoo. One of the turtles, a loggerhead was found near the St. Lucie Nuclear Power in March in a debilitated state, enveloped by barnacles and suffering from a liver issue. Meanwhile, the other green sea turtle was also found in March. It suffered from a fractured shell as well as a damaged flipper.

Such rescues truly make a big difference, and it's an encouraging to see despite recent problems in the decline in sea turtle population.
