Conservation, marine science, Natural Science, Science, sharksJune 1, 2011

Oceanic whitetip sharks are considered by many to be a poster-child for shark conservation. Once one of the most abundant species of pelagic sharks on Earth, unregulated overfishing throughout their global range had led to a¬†precipitous¬†decline in their population.

State of the Field: Satellite tagging sharks

marine science, Natural Science, Science, State of the FieldFebruary 15, 2011

Modern shark researchers have access to a variety of high-tech tools. Acoustic tags with noises specific to each individual shark signal a receiver (or network of receivers) every time the shark passes nearby. Some tags have three-dimensional accelerometers, allowing researchers to study the small scale movement patterns and behaviors of sharks. Others, which are placed […]
