A selection of video clips of our team scanning the beaches in Gunner Point by the golf course in Hayling Island.
Small Radio Frequency Identification (RFID) tags are embedded within native pebbles collected from a site of interest and secured with a waterproof resin.
The pebbles are then deployed and re-surveyed at set intervals using a specialised scanner and a Global Positioning System (GPS). The RFID tags are passive, meaning that they have no internal power source and can remain in situ for long periods. The tag only broadcasts a unique identification number when detected with the scanner, which can be logged together with the GPS to establish an accurate position
This method helps us to better understand local coastal processes, which in turn, supports local coastal management decisions, aids coastal defence scheme design and informs local beach maintenance activities, such as recycling and replenishment campaigns.
