The Group for Aquatic Primary Productivity (GAP) arose in 1980 from discussions during the SIL Congress in Kyoto.
Originally conceived by Zvy Dubinsky, Max Tilzer, Mitsuro Sakamoto and Tom Berman, the GAP format is unique in that it is a hands-on Workshop, focusing on topics relevant to measuring aquatic primary production, intended to attract both freshwater and marine scientists.
Although Workshops usually have a day of presentations where senior scientists present overviews of topics of relevance to the overall focus of the meeting, the main part of the Workshops is devoted to experiments. Participants bring state-of-the-art equipment and methodology to run experiments over the course of the meeting (usually around a week to 10 days), the results of which are later published in a peer-reviewed journal. Attendees are a mix of distinguished elder practitioners, younger scientists and students to enhance exchange of experience and expertise.
To date there have been 9 such GAP Workshops, the most recent being held in Malaga, Spain, in 2012. The International Organizing Committee [John Beardall (Australia), Vivian Montecino (Chile), Ilana Berman-Frank (Israel), Pat Neale (USA), Katrin Teubner (Austria), Jacco Kromkamp (The Netherlands) and Félix Figueroa (Spain)] is currently considering bids from institutes to host GAP10, which will be held in 2017.
