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: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
