Rationale and aim

 

 

 

 

 

Understanding of the metabolic balance in planktonic ecosystems and how biology influences the aquatic carbon cycle is hindered by current disagreements within and between the microbiological, ecological and biogeochemical approaches to measuring respiration. There exist live, unresolved debates about the balance of plankton photosynthesis and respiration in the ocean, and therefore about the fundamental question of whether the ocean is a net source or sink for atmospheric CO2

 

This Workshop aims to convene researchers working at different scales on planktonic R in the ocean, coastal waters, estuaries and lakes to debate whether the root of this controversy lies in unresolved methodological problems, uncertainties on interactions between systems, difficulties for scaling, or limitations to our basic knowledge of pelagic trophic dynamics or biogeochemistry.

 

 

 Objective and topics

 

This Workshop will be an open forum where researchers can examine closely the data, conjectures, and methods to resolve the conflicts about whether the ocean, coastal waters, estuaries and lakes are net heterotrophic, and if so, why and how. Its main objective is to nurture new collaborations and advance towards a coordinated research agenda to address the disparities between geochemical mass balances observed at the scale of entire oceans, and biological rates observed in a few hundred millilitres of seawater. Among the questions we may ask are:

1.  What respiratory pathways exist in planktonic food webs?

2.  How important is respiration in determining whether the ocean is a net source or sink for CO2?

3.  How is respiration distributed among the components (bacteria, phytoplankton, microzooplankton) of the planktonic food web?

4.  How is respiration controlled by environmental factors, and how will climate change influence the relative magnitude of respiration in the ocean?

5.  Do the separate oceans, lakes, and estuaries differ with respect to their metabolic balance? If so, how and why?

6.  How does respiration change seasonally, and with trophic structure?

7.  What is the role of organic matter supplied from outside the system to food web dynamics and fluxes?

8.  What causes the current disparities between microbiological, ecological and biogeochemical estimations of aquatic respiration?

9.  Do we have tools for the remote estimation of R?

10. Can we agree on scaling rules to extrapolate from local food-web flux measurements to regional or global biogeochemical rates?

This is an open workshop. If you are interested in dealing with any specific topic, or want to suggest a theme or breakout group of discussion, contact us.

 

 Programme and agenda

 

The workshop will precede the 2005 ASLO Summer Meeting in Santiago de Compostela (located 86 km to the North of Vigo), where Peter J. Le B. Williams and Paul A. del Giorgio will organize a Special Session on Respiration in Aquatic Ecosystems: Current Understanding and Future Directions. This workshop is designed to be complementary to the ASLO meeting. The workshop will provide an opportunity for the extended discussion and in-depth interaction that is necessary for the emergence of new multidisciplinary collaborations, which may be difficult to obtain in a larger-scale conference. The agreed collaboration between the two activities will take form in the presentation by the Organizing Committee of a synopsis of the results of the workshop at the ASLO meeting.

The Workshop will take four days. The workshop agenda will be subdivided into the three areas, (1) the past: and historical perspective; (2) the present: current status; and (3) the future: the ‘next steps’ in research on respiration in planktonic food webs.

We expect that (1) and (2) will be summarized in the first day-and-a-half of the workshop by means of keynote presentations of 30 minutes duration with long discussion periods (15 min), oral presentations of 15 minutes duration with 10 minutes for discussion, and poster sessions.

The second and third days will be devoted to evaluate the first day’s information and to discuss existing challenges, problems, and issues to be resolved. To this end, small, breakout, groups may be formed either along disciplinary lines (biogeochemistry, biological rates, methods) or ecosystems (estuaries, lakes, oceans). On the last day, the results of these deliberations will be presented and discussed. We can expect that several research themes will emerge, and therefore the Workshop will define the next steps in the research, and develop a plan for future collaborations.

The following workshop schedule is designed to accommodate to the peculiar Spanish time table (for a thorough explanation, see http://aslo.org/meetings/santiago2005/santiago.html#times).

 Dissemination

 

Dissemination of workshop conclusions will be agreed with workshop participants. Current plans by the Organizing Committee take three forms.

First, the Organizing Committee will present a synopsis of the results of the workshop at the ASLO meeting one week following the Workshop. Such presentation has been agreed with Peter J. Le B. Williams and Paul A. del Giorgio, organizers of the Special Session on Respiration in Aquatic Ecosystems: Current Understanding and Future Directions. That way, we can generate interest and feedback in our activities from the broader research community, and maintain the momentum that the Workshop will create.

Second, the Workshop Organizing Committee will prepare a Workshop Report which will include (1) a summary of the presentations and associated discussion, (2) a listing of abstracts for the presentations and posters, (3) an address list of attendees, (4) a set of statements of next steps in research on aquatic respiration. The Workshop Report will be distributed to the major international programs in biological oceanography and biogeochemistry, such as JGOFS, GLOBEC, SOLAS, CLIVAR, and IMBER.

Third, the Organizing Committee will prepare a report of the Workshop to be published in the Limnology and Oceanography Bulletin, a peer-reviewed newsletter that is distributed to all members of ASLO. A similar report will be prepared for publication in EOS, a newsletter published by the American Geophysical Union. The EOS report will reach beyond the ecological to the broader biogeochemical community.

Vigo/Tourism

 
 

Vigo is Galicia’s largest city, and Europe’s largest fishing port. It is also a touristic spot in Spain because of its landscape, beaches, weather and food. It is located right by the sea at the southernmost of the Galician Rías, 30 km North of the Portuguese border, and both the landscape and the economic and social life of the city are closely connected to the sea. The Atlantic coast of Galicia, and the rías in particular, are between the most productive coastal seas in the World, because of the influence of a wind-driven coastal upwelling throughout the summer (www.iim.csic.es/~rbos/aflora.htm). Vigo, and the whole county of Rías Baixas, is famous because of its seafood, and because it is home of some of the best Spanish white wines, including Albariño (www.doriasbaixas.com). The weather during June is usually warm (15-30 °C) and sunny, which helps enjoying the many beaches around (http://hoxe.vigo.org/conecenos/praias.php?lang=cas), easily accesible by local buses. The Cíes Islands, located at the mouth of the Ría de Vigo are part of the recently created National Park of the Atlantic Islands, and can be reached by ferry from Vigo. For those aiming to know Galicia, the coastal and dynamic city of Vigo represents a perfect complement to the cultural heritage of the inland Santiago de Compostela (for information about Spain, Galicia and Santiago, see the 2005 ASLO Summer Meeting site at http://aslo.org/meetings/santiago2005/santiago.html).

Vigo is also a unique city in Spain regarding marine science as it holds research centres of both the Spanish Institute of Oceanography (www.vi.ieo.es/), the National Research Council (www.iim.csic.es), and the Faculty of Marine Sciences at the University (www.uvigo.es), as well as a foundation for marine technologies of the Regional Administration (www.cetmar.org).

You may find further interesting information on travelling, staying and enjoying Vigo at the websites of the 2004 ICES Annual Science Conference (www.atlanticocongresos.com/ices2004/), Vigo City Council (www.vigo.org/ingindexorg.php?lang=ing) and Turgalicia (a company promoting tourism in Galicia)(www.turgalicia.es).
