Phase I: The first phase of the workshop will be a videoconference work session among key US/NZ players. The goal of this meeting is to develop a list of datasets/measurements that are most critical for identifying and monitoring the key processes involved in Dry Valley ecosystem change. This working group will identify the issues people will work on in preparation for a second, 2-day meeting prior to SCAR (July 14-15). The gist of the first meeting consists of a discussion of summaries of current measurements (locations, frequency etc.,), and identifying recent advances that might change or improve those currently implemented. A workshop website will be developed where participants in the Phase II workshop (see below) can download beforehand the information from the initial US/ANZ work session and participant responses. This will allow us to hit the Phase II workshop in stride – all the information produced by the Phase I workshop will be available to the Phase II participants before they arrive at the meeting so that they can ruminate and come ready to debate/inform/generate the sought after workshop end-products.
The formal, proposed workshop will start with one introductory presentation on how to set up a terrestrial observation network by 1-2 people with 'rubber hits the road' experience setting up a similar framework in Arctic ecosystems (i.e. CBMP). This will be followed by 4 synthesis-type presentations of what the US and ANZ is currently measuring (one presentation each, 2 by US and 2 by Kiwi scientists, to cover the major processes associated with environmental change).
Following these synthesis presentations we will take discussion from other attendees on successful measurements in their respective systems/programs. The mechanism for this session of the Phase II workshop will consist of breakout groups divided by environmental change processes and landscape feature (lake, stream, soils, glacier) and include representation from multiple disciplines (biologists, biogeochemists, modelers, glaciologists, etc.). Participants in the breakout sessions will further detail the other main objectives of the workshop with consideration/constraint of a 10-year time frame for full implementation. Emphasis will be placed in identifying new technologies, models, instruments, analytical tools, and GIS/geospatial applications.
The intended products are:
- Lists of monitored processes for each major ecosystem component
- Data collection standards (instrumentation, methods, timing, periodicity, spatial scale, etc.)
- An assessment mechanism to determine the effectiveness of current Dry Valley management guidelines
- Charge to individuals/groups to produce manuscripts that inform assessments of environmental protection and management policy (i.e. Environmental Monitoring and Assessment)
- A workshop summary to be submitted to EOS
- A more detailed summary/list of findings and recommendations to be submitted for publication in Antarctic Science
(a more detailed agenda of the workshop is forthcoming)
