Scientists are turning sharks into hurricane trackers by using them as roaming ocean sensors
Researchers say tagged sharks can relay temperature, depth and location data, offering a lower-cost way to track hurricanes.
- University of Delaware researcher Aaron Carlisle is leading a project using tagged sharks as mobile ocean sensors to improve hurricane predictions, recording critical data throughout the water column that satellites cannot capture.
- Tracking conditions around hurricanes can be expensive, with ships costing tens of thousands of dollars daily and gliders reaching up to $1 million each, making sharks an attractive alternative.
- OCEARCH scientist Harley Newton assured that tagging does not harm sharks, likening the process to an earlobe piercing. When sharks resurface, they transmit critical water temperature and depth data.
- Fischer noted that linking shark movement data with weather patterns offers potential insights for hurricane dynamics, though OCEARCH is not directly involved in Carlisle's project.
- Since 2007, OCEARCH has tagged nearly 500 sharks aiming to build a complete life history of the species. Scientists hope to tag a handful more this year to expand the dataset.
