The Dorset Alum & Copperas Project. (funded by English Heritage)   Interim Reports now posted - see Reports Kimmeridge Fieldwork - 8th - 15th February 2010 (photo diary) Sampling of the  industrial deposits exposed on the bank above the shore has now completed ready for analysis.      Studland excavation  1st - 8th September 2009 (photo diary) No conclusion as to the purpose or date of these earthworks can be determined from the prelimnary results. There were no significant finds to give any clue to their date but the thin layer of heather and peaty topsoil would suggest they are fairly recent, only just predating the time they were first recorded in the mid 19th century.  It is hoped analysis of the samples taken will help understand their function.       Brownsea Island excavation  - May 2008 (photo diary) An excavation on the South Shore of the brick lined tank eroding out of the bank which is believed to be the site of the 16th century copperas works. Shoreline survey. Some members are engaged in a shoreline survey to record features around the harbour - these are arranged at short notice to fit with tide and weather conditions.  It is hoped to arrange more training sessions later in the year. For a shoreline survey low tides are best ‘followed out’ so be ready to go up to 1 hour before the predicted low max.  Spring lows are normally early morning or late afternoon/  evening.  Best lows are in the spring/autumn but can restrict time available because of limited daylight hours.  Some reasonably lows occur in the early afternoon which are ideal for a shoreline survey. There are many features around the Harbour that are exposed at low tide and therefore easier to record for further investigation or to make a more detailed survey.  Timing is often rather at short notice so if you want to get involved register your interest with contact details. Access to some of the shore areas around the Harbour is restricted and before entering onto private land the necessary permission should be obtained.                                 SAFETY FIRST TIDES              Poole Bay and Harbour has an unusual tide pattern which results in long ‘stands’ at some highs – the movement between stands sometimes less that 0.50 of a metre and these periods are ideal for exploring with a light boat  Even the tidal movement at Springs is moderate with around 1.7m between high and low water.                                                       Always be careful of the environment when walking the shores around the Harbour – some can be dangerous and it is best to work with a team. Appropriate clothing and footwear should be worn at all times.
