Second circular CROSS-­‐PROGRAM SCAR WORKSHOP ON "INTERACTIONS BETWEEN BIOLOGICAL AND CLIMATE PROCESSES IN THE ANTARCTIC" AnT-ERA
www.scar.org/srp/ant-era
Antarc'cClimate21
The aim is to develop new interdisciplinary cooperation, gathering opportunities, demands, and perspectives from biological and environmental/physical disciplines. 18 June 2015 Notes for participants: This is a brain-­‐storming workshop, thus time for 1st day's presentations is short. They should not have more than 2-­‐3 slides (incl. title) and not be longer than 4 min! They should focus on: 1. scientific questions, which are difficult to be answered now, but maybe in the future (through interdisciplinary cooperation). 2. which parameters you need (as a biologist)? 3. which parameters you can provide (as a physicists)? Even don't try to present results, 4 minutes are even not enough for a short summary! The approach is not novel, rather a continuation of ongoing initiatives, e.g. SCAR Horizon Scan, but with an emphasize on the implementation of new studies. The structure of the workshop is open, especially the wording of the topics and the affiliation of the participants to the topics. Topics (=fields of interest) are pre-­‐clustered according to the information you provided in the questionnaires. If major aspects are missing I will try to consider them before the workshop. Other recommendations, especially affiliation of participants to the topics can be considered/discussed during the workshop (preferably end of day 1, beginning of day 2). I will soon approach some of you to ask you to lead a session and act eventually as a lead-­‐
author (see below for one page each). Volunteers are welcome and should respond until 25 June. Also open is the output of the workshop. To my opinion the best output would be interdisciplinary proposals written after the workshop, which had not been written without the workshop. It is too ambitious to effort this during the workshop. Maybe this workshop can stimulate smaller follow-­‐up workshops, which are focussed on proposals. A majority of you (maybe 70%) voted for a paper as the workshop's output. This must be a community-­‐
driven approach. Here a first idea is provided how to structure it. The idea is to provide for each topic (not necessarily all) one page, in which we describe points 1-­‐3 (above), incl. physical and intellectual resources needed. These single ideas (=pages) can be merged to a workshop-­‐output paper (discussion end of day 1). They could also be the basis for possible proposals or outlines of PhD theses. This will be a low-­‐budget (high efficiency) workshop. No conference fee; coffee, workshop dinner & farewell wine provided by the organising programs. Lunch is up to you, there are several opportunities around the venue. Any veggies (info needed for workshop dinner)? It is recommended to look at http://www.barcelona.de/de/barcelona-­‐festes-­‐la-­‐merce.html Inexpensive airport transfer by Aerobus to/from Plaza Catalunya (EUR 6 one way, you must have small money, max. accepted: 20€ bills). From Plaza Catalunya to other places by metro, e.g. to Barceloneta use line 1 (red) direction Fondo and change at station Urquinaona to line 4 (yellow) direction La Pau, step out at station Barceloneta (10-­‐trip ticket is most convenient/cheap).
The workshop topics Condensed from the information provided by in the questionnaire. Possible speakers of the groups in bold (one biologist and one physicist for each group). Affiliation of participants to topic groups very preliminary. 1. Important biogeochemical and macroecological spatio-­‐temporal scales, driven by the physics (climate vs microclimate)? Identification of the modulating drivers and possible feedbacks? (Constable, Stevens, David, Domack, Schofield, Convey) This seems to be an overarching topic of interest for all of us. Maybe useful for an introduction but not so much for a focussed topical paragraph. 2a. Development of risk maps linking environmental constraints incl. UV, to biodiversity, ecosystem functioning, services and goods (Bodeker, David, Jopp, Bertler) 2b. Modelling SO ecoregions. Regional Ocean Modelling with the focus of microbes and currents (David, Jopp, Bodeker, Schiaparelli, Murray) 3a. Organism response (or plasticity) to climate change using measurements and predictive models (Verde, Jopp, di Prisco, Griffiths, England, Bertler) 3b. Drivers, and their vulnerability to climate change; resilience of and thresholds of benthic biota (Post, di Prisco, Griffiths, Schröder) 4a. Large-­‐scale ecosystem response to climate change using measurements and predictive models incl. sea-­‐ice (Jopp, Griffiths, England, Schröder, Schofield, Cavangh) 4b. Assessment of the relative importance of natural climate variability versus anthropogenic change? (Bracegirdle) 4c. Influence of physical processes, incl. multiple stressors, e.g. vertical mixing, pH and temperature, on phytoplankton bloom dynamics and food-­‐web interactions (Trimborn, Schloss, Russell) 5a. Physical drivers of top predators and squid (Xavier, NN (physics), Ropert-­‐Coudert) 5b. End-­‐to-­‐end ecosystem modelling, (Constable, Xavier) 6a. Effect of physical oceanographic forcing on patterns of productivity, glacial melt and sedimentation in SO near-­‐shore ecosystems e.g. silled fjords West of the Antarctic Peninsula and on land-­‐ocean interactions (Smith, Schloss, England, Cummings) 6b. Off shore peninsula warming and ecological dynamics (Schofield, Bracegirdle) 6c. Impact of ice sheet dynamics on SO ecosystems; rates and magnitude of future ice shelf and ice sheet retreat (DeMaster, DeConto, Domack, Scherer, Isla) 7. Physical/biological seaice-­‐ocean and seaice-­‐atmosphere boundary layers and impact of changes on primary production and other biological processes. (Murray, Stefels, Stevens, Comiso, Bertler, Bracegirdle) 8. Evolution of biota related to glaciation history, marine and terrestrial glacial refugia, Transantarctic seaway (DeMaster, Wilson, Convey, Scherer, Imura, Strugnell) 9. Are regional and local changes in physical control altering terrestrial and limnic biodiversity, biological processes, mosses, and soil biogeochemistry? Other physical drivers, boundary conditions, thresholds, and risk (Wall, Ott, Imura, Bracegirdle, Nielsen, Kahn, Verleye)
