Dr. Ian Spooner (Acadia University, Nova Scotia) is an environmental scientist who uses lake sediment records to determine how development, atmospheric pollution and local geology influence lake water quality and chemistry. Over the past seven years he and his students along with staff at Cascade Environmental Resource Group have studied the sediment records in Alta Lake and, more recently, Lost Lake.
Both lakes have provided detailed and complex records of environmental change dating back to the 1700s. Research to date has indicated that both natural processes and anthropogenic influences have had a significant impact; the data provides some guidance for future development in both watersheds.
Thursday, April 11 Ian will be at the museum to show how the lake records were obtained and analyzed and discuss what they can tell us about both the resilience and vulnerability of these lakes to future environmental change. Local context (written records, personal experiences) is critical to effective interpretation of the lake sediment records and he hopes that everyone who has an interest in or a story about our lakes can attend.
