Dear Colleagues,

The deadline to apply for this year’s Gordon Research Conference on Catchment Science (14-19 June 2015, Proctor Academy) is fast approaching.   The 2015 GRC speakers and discussion leaders promise to be an impressive and engaging group and, as always, there will be time for significant interaction with stimulating international colleagues over posters and meals-- as well as while exploring the New Hampshire land- and water- scapes. 

We look forward to seeing you in June. 

Apply now to attend. 

Best,

Kathleen and Jan Seibert, co-Chairs
