This is a report from the INTERICE 5 project that used the Arctic Environment Test Basin at HSVA from 21 May to 19 June 2012. The overarching aim was to investigate the physical and biological controls of dissolved organic matter incorporation into growing sea ice and the effect of melting once the ice had consolidated. Measurements were also made on the CO2 fluxes at the ice surface in relation to the chemical and biological changes taking place in the ice. The Interice 5 team was a multidisciplinary group of glaciologists, chemists and microbiologists from Belgium, Denmark, Finland, Germany and U.K. They were able to build on the experiences of previous INTERICE 2, 3 & 4 projects to maximize the opportunities from the facility. The preliminary results from the experiment will be presented, in the context of what is known about these processes from field campaigns.
