The FROG is the Foreshore Recording & Observation Group. It is is made up of 200+ volunteers who have been fully trained in foreshore recording techniques and health & safety and have been certificated by the TDP.

What Does the FROG Do?

The FROG has adopted one of the 20 key sites of archaeological interest, found on the Thames foreshore, and they assist with the monitoring each of these sites. We hope that the FROG community will be able to take responsibility for monitoring these sites and other areas with archaeological remains on the foreshore for many years to come!

Health and Safety

Please be aware that our FROG group and foreshore visits are all subject to the vagaries of the tide timetable, so work may, at times, be early in the morning and at weekends, or canceled at short notice if the low tides on paper do not appear in fact. Some of the foreshore sites are only exposed at certain times of the year with very low tides. Rainfall affects the tide on the Thames and heavy rains in the areas along the source or tributaries of the Thames in other parts of the country will affect the Thames in London. We have very strict Health and Safety requirements, and all FROG group members are covered by Thames Discovery Programme insurance during their FROG visits – this will not be the case if you “go it alone”. You can find out more about foreshore Health and Safety essentials on the foreshore safety page.
