Resum:

The ALeRT (Archéologie, Littoral et Réchauffement Terrestre) project has brought together researchers involved in coastal archaeology and aims to establish an interdisciplinary approach to assessing coastal archaeological vulnerability, site monitoring and heritage management. The scale of the problem and the need for improved field data collection and data management procedures led us to develop a web and mobile application for adding field data and administering users. This reduces the time of data collection in the field and widens the opportunities for collaboration between researchers, heritage managers and the wider community. Recent extreme weather impacts on coastal archaeology in Brittany has led to a growing interest in public archaeology initiatives and resulted in a huge mobilisation of the local population. As a result of this, a specific training programme in coastal archaeology was developed for coastguards and local communities. The ALeRT network is formed of 30 active members who cover almost the whole coast of the region, and this network has been recently augmented through a partnership with the Conservatoire du Littoral, a public wildlife conservation organisation. In this paper we will focus on the results of the collaborative project undertaken in 2014 and 2015, when this citizen science approach was put to the test.
