Negligible impact on public safety from shark cage diving operations

16.07.2009
According to research at the University of Hawaii at Manoa

A study by five university researchers—including four from the University of Hawai'i at Mânoa—concludes that existing shark cage diving enterprises in Hawai'i have a negligible effect on public safety.

The paper, "Seasonal cycles and long-term trends in abundance and species composition of sharks associated with cage diving ecotourism activities in Hawai'i," is authored by Carl G. Meyer, Jonathan J. Dale, Yannis P. Papastamatiou, Nicholas M. Whitney and Kim N. Holland, and has been published in the online section of the Environmental Conservation journal.

Meyer, Dale, Papastamatiou and Holland are researchers with the UH Mânoa Hawai'i Institute of Marine Biology at Coconut Island, while Whitney works at the Mote Marine Laboratory in Sarasota, Florida.

The scientists collected and analyzed logbook data from two O'ahu shark cage diving operations from 2004-08 to obtain "useful insights into shark ecology or ecotourism impacts." Those impacts on public safety were deemed to be "negligible," due to factors such as remoteness of the sites, and conditioning stimuli that are specific to the tour operations and different from inshore recreational stimuli.

The study also notes that there has been "no increase in shark attacks on the north coast of O'ahu since cage diving started."

The University of Hawai`i at Mânoa serves approximately 20,000 students pursuing 225 different degrees. Coming from every Hawaiian island, every state in the nation, and more than 100 countries, UH Mânoa students matriculate in an enriching environment for the global exchange of ideas.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
