Presentation Transcript

  1. Lake Metabolism Working Group GLEON 8 notes

  2. Who • Paul Hanson, Susan Hendricks (moderators) • Denise Bruesewitz, Julita Dunalska, Zhenqwen Liu, Boping Han, Ami Nishri, Matthew Hipsey, Tiina Noges, Chris Solomon, Kevin Rose, Darren Bade, Bill Perry

  3. Progress • Background discussion, updates from GLEON 7 • Metabolism discussion of parameters, assumptions (Future Outcome: sharing of “best practices” paper) • Modeling for lake metabolism • GPP/R variation projects

  4. Project Descriptions • Variation in GPP/R • Goal: analyzed lake metabolism data for discussion available at GLEON 9 • Collection of potential driver data • Leaders: Chris, Kevin, Denise, Julita • Involvement and data request email to immediately follow meeting

  5. Modelling of Lake Metabolism • What assumptions are implicit when oxygen data from a specific depth is used to estimate whole lake metabolism? • Modelling approach may be a useful method of future analyses • Use high resolution models to upscale single point estimates of lake metabolism • Useful to explore assumptions analysis technique (eg. atmospheric flux; respiration) • Project needs data to inform models • Leaders: Darren Bade, Matt Hipsey • Goal: project update at “Cool Things” session at GLEON 9 • Potential methods paper

  6. From Lake Metabolism Analysis: • Res = 0.73 mgDO/L/day ~ 0.07 /day • GPP = ?? • Atm = 0.00071 mg/L/day
