Deployment - 2011
Following the successful trial, a further 1000 pebbles were deployed around Eastoke during March 2011 and 350 were deployed along the western end of the frontage, close to the entrance of Langstone Harbour. This made a total of 14 deployment sites along the Hayling Island frontage, with each site selected specifically to provide valuable information on longshore drift rates and direction.
- The sites at Eastoke were selected to help locate the position of a drift divide, this is the point at which the onshore transport of material either moves eastwards towards Eastoke Point or westwards towards the open beach;
- The sites around Gunner Point were chosen to aid understanding of the transport and build-up of material around this large sand and shingle cuspate headland.

Intensive monitoring surveys were conducted after the first week of deployment and were then carried out then approximately every 1-2 months for the first year in the field. After one year an additional retrieval survey was carried out in 2012.
