Hi all First of all a belated thanks to all those that took the time to reply to a message about a month ago regarding quotes for sulphur analysis. I eventually got sorted. This message is a call to any GIS experts out there who can help with a plotting problem Im having for some soil isotope data. To my novice eyes it seems a simple solution but please message me offline if interested for further information, there would be appropriate accreditation in a subsequent publication Many thanks Neil Dr Neil Ogle Queen’s University Belfast School of Natural and Built Environment Stranmillis Road Belfast BT9 5AG
