ddb visited the Universities of Stockholm and Uppsala, where he gave presentations on greenhouse gas flux studies in the Delta. The main purpose was to serve as the opponent of the PhD defense of Eva Podgrajsek, Lake fluxes of carbon dioxide and methane. He also visited the new lake flux site on Lake Erken, http://www.ebc.uu.se/Research/IEG/erken/?languageId=1. The Uppsala group of Erik Sahlee and Anna Rutgersson are actively measuring eddy fluxes over lakes in Sweden and the Baltic sea. The Stockholm group of Patrick Crill are doing novel work in the Arctic measuring methane fluxes of fens, bogs and lakes and are looking at the sources of production with stable isotopes and linking biogeochemical function with genomics, protenomics and transcriptonomics. They are also making novel measurements of bubble fluxes. Lot learned on the trip.
Joe Verfaillie, Cove Sturtevant, Siyan Ma, Patty Oikawa, Sara Knox and Housen Chu participated in the Ameriflux Data workshop at Lawrence Berkeley National Lab.

Jose Fuentes of Penn State visited the Biometlab while on campus giving a BASC symposium lecture
ddb gave a presentation on eddy covariance, a method for measuring ecosystem-atmosphere fluxes of trace gases at 2015 Aquatic Sciences meeting of the Association of the Sciences of Limnology and Oceanography in Granada, Spain.
Presentations on the Fluxnet project were give at the Vrije University, near Amsterdam. While in Wageningen, seminars were given on the greenhouse gas studies in the Delta and on Fluxnet.
