From Nairn to San Diego... CEH lake restoration research hits the road

Details of CEH lake research were presented at an international conference last week by one of our former PhD students:

Dr Sebastian Meis presented results of his PhD study at the 33rd International Symposium of the North American Lake Management Society (NALMS: 30 October - 3 November 2013) in San Diego, USA. In his presentation, entitled "Seasonal responses of physicochemical and biological variables following disruption of internal phosphorus loading using lanthanum-modified bentonite clay (Phoslock®): insights from laboratory and whole lake experiments", he highlighted the major findings of the whole lake manipulation study conducted at Loch Flemington (Nairn, UK) by CEH.

The conference focused on measures for in-lake phosphorus control available to lake managers, with various presentations focusing on the use of alum, oxygenation / aeration and de-stratification as possible management tools. Conference attendees included scientists, lake managers, consultancies, as well as companies. Dr Meis was also invited to present at an additional special session on the use of geo-engineering approaches for phosphorus management in lakes, where he highlighted the need for greater accuracy when estimating product dose at the site specific scale.

Dr Bryan Spears, a co-author on the talk and Sebastian's supervisor during his PhD, writes:

"It's great to see the importance of Seb's work being recognised through his invitation to present at the special session. Geo-engineering is being increasingly used for the control of phosphorus and eutrophication in lakes. CEH's role as an independent research organisation in informing water managers on issues associated with this approach is critical. Seb's recent work has provided scientific evidence with which decisions on the wide-scale use of this approach can be based.

This work has produced guidance on estimating effective dose of products and the identification of potential unintended chemical and ecological consequences associated with product application. Seb's results are being used to inform industry and environmental regulators on the wider use of this approach."
