Two years after destroying part of the Belize barrier reef, an U.S. skipper has been ordered by a Belize court to pay BZ$3.4 million, roughly equivalent of US$1.7 million, for the damage.

On May 2, 2007, the skipper was trying to reach harbour in his double hull catamaran when it ran aground in the Lighthouse Reef Atoll, causing damage to a piece of the reef measuring 125 feet by 75 feet.

Belizean magistrate Ed Usher ruled that the skipper did not exercise due diligence in navigating the atoll. Since the catamaran was so large, 37 feet x 21 feet, the person in charge should have hired a pilot and sufficient crew to navigate the reef safely. By neglecting to do so, the skipper recklessly caused a disaster that resulted in a loss to the environment.

The skipper must pay BZ$50,000 (US$25,000) within two months, but have been given a five year respite for the remainder of the fine. His catamaran, estimated to be worth around US$300,000, will however be held by Belizean authorities until he comes up with the money.

As part of a reef restoration study, researchers removed 20 specimens of the Caribbean giant barrel sponge from the Conch Reef off of Key Largo, Florida and then re-attached them using sponge holders consisting of polyvinyl chloride piping. The sponge holders were anchored in concrete blocks set on a plastic mesh base. Some sponges were reattached at a depth of 15 meters and some further down at 30 metres.

The results of the study now show that sponges are capable of reattaching themselves to reefs if we help them by keeping them properly secured during the recuperation period. After being held stationary by sponge holders for as little as 6 months the sponges had reattached themselves to the Conch Reef. Of the 20 specimens reattached in 2004 and 2005, 62.5 percent survived at least 2.3-3 years and 90 percent of the sponges attached in deep water locations survived. During the study period, the area endured no less than four hurricanes.

This is very good news for anyone interested in reef restoration, since the new technique can be used to rescue sponges that have been dislodged from reefs by human activities or storms. Each year, a large number of sponges are extricated from reefs by human activities such as vessel groundings and the cutting movements of chains and ropes moving along with debris in strong currents. Severe storms can also rip sponges from the reef, which wouldn’t be a problem if it weren’t for the fact that so many sponges are also being removed by human activities. When combined, storms and human activities risk decimating sponge populations. Old sponges can be hundreds or even thousands of years old and their diameter can exceed 1 meter (over 3 feet). Sponges of such an impressive size and age can naturally not be rapidly replaced by new sponges if they die.

Sponges can survive for quite a while after being dislodged but is difficult for them to reattach themselves to reefs without any help since they tend to be swept away by currents and end up between reef spurs on sand or rubble, where they slowly erode and eventually die.

“The worldwide decline of coral reef ecosystems has prompted many local restoration efforts, which typically focus on reattachment of reef-building corals,” says Professor Joseph Pawlik of the University of North Carolina-Wilmington, co-author of the study. “Despite their dominance on coral reefs, large sponges are generally excluded from restoration efforts because of a lack of suitable methods for sponge reattachment.”

The results of the study, which were published in Restoration Ecology, show that we can help the sponges to survive by using the new technique. Earlier attempts were less successful since they relied on cement or epoxy; two types of adhesives that do not bind well to sponge tissue.

Last week, a leaping 9-foot dolphin accidently ended up in an 18-foot boat in the Intracoastal Waterway near New Smyrna Beach, Florida. As the panicked animal tried to escape from the vessel, it repeatedly hit the two boaters, 64-year-old Norman Howard and his wife Barbara, with its powerful tailfin.

“It was slapping me pretty hard,” Howard said. “Yeah, it was throwing some good punches. Mike Tyson couldn’t hit harder than that.“

The U.S. Coast Guard arrived to the scene after receiving calls from witnesses of the weird accident, and promptly rushed the couple to Bert Fish Medical Center. Howard says he was smacked in the face and ribs, while his wife received lacerations to her face.

The dolphin could be rolled back into the Intracoastal Waterway after the accident.

Many dolphin species are agile jumpers and the Bottlenose dolphin (Tursiops truncatus) is for instance known to leap up to 10 feet (3 metres) or more. The maximal height of a leap depends on the individual animal and the surrounding water, since the dolphin uses its flukes to projectile itself into the air. In shallow waters, dolphins cannot jump very high.
