Chequamegon Ecosystem Atmosphere Study (ChEAS)
Annual Research Meeting
Dates: June 29 - July 3, 2003
Location: Kemp Natural Resources Station, Woodruff, Wisconsin
The Chequamegon
Ecosystem-Atmosphere Study (ChEAS) is a multi-organizational research effort
studying biosphere / atmosphere interactions within northern mixed forests in
Northern Wisconsin and Michigan. The unifying goal of ChEAS is to understand the
processes controlling forest-atmosphere exchange of carbon dioxide and water on
the regional scale and
the response of these processes to climate and land-use change. Our annual
summer meeting brings together a wide range of participants from within and
outside of the ChEAS network to focus on approaches to measure and explain interannual variability in NEE of northern temperate forests.
This meeting is supported by a Research Collaboration Network grant from the
National Science Foundation. This grant also provides funding for exchange of
research staff among participating ChEAS research groups. Click
here for more information.
What is the purpose of the annual meeting?
1) The annual meeting brings together ChEAS investigators to exchange research
results and make plans for future research. To this end, the meeting includes
time for research presentations and discussion time. Existing investigators
are encouraged to attend, and present research progress and future plans.
Investigators are encouraged to bring recent publications and to provide
presentations and other materials that can be linked to the ChEAS web page (http://cheas.psu.edu).
NSF funds are available to support travel so that students and postdocs can
attend in addition to project PIs. Students are encouraged to bring brief
presentations of their graduate research plans, and ideas for exchanges with
other groups that will enhance their research and the integration of ChEAS
results.
2) The annual meeting also allows new investigators, or those interested in
becoming involved with ChEAS research to become oriented in a short period of
time via first-hand discussion with a large number of ChEAS PIs, students and
staff. New or potential investigators, including students, are encouraged to
attend. There will be introductory presentations, field site visits (to be
arranged pending requests from attendees) and discussion time. Limited travel
funding is available. Our workshops (2002, 2004, 2006) include more extensive
training and educational activities.
This year's meeting will include discussions of
1) Integrating our work with the North American Carbon Program. ChEAS Research
is a strong match for the types of regional intensive field research called for
in NACP planning documents. How can we respond to this opportunity/challenge?
2) New results from our flux towers and associate measurements for the past
year, focusing especially on the new science possible given the density and
variety of flux measurement sites currently operating in the ChEAS domain.
3) Ongoing/new field projects including tower-biometric comparisons, a roving
soil flux intercomparison project, and a demonstration regional inversion
project.
Other suggestions for areas of focus are welcome.
Preregistration is encouraged to ensure on-site accommodations. Funding is
available to cover costs of workshop attendance (transportation, lodging, and
food) for a limited number of participants. Preference will be given to advanced
undergraduate students, graduate students, and postdoctoral researchers from
participating ChEAS labs, though support for all participants who request it
will be considered. Low meeting costs have made fairly comprehensive support
possible in the past.
To register, please fill out the following information and return it to Diane
Yoder at The Pennsylvania State University
(dyoder@meteo.psu.edu) as soon as possible (preferably before June 20, 2003).

Meeting Schedule
This is a tentative agenda. Times and titles can be changed. Presentations and
activities can be added or removed. Please read it over and see where your name
occurs!
Guidelines for talks: Bring publications to share or at least references. Emphasize collaborative needs or plans, since we’ll all be together. Recommend future studies, publications, proposals during the course of your presentation.
Grad student talks: Be sure to briefly outline your degree research plans. Present your ideas on lab exchanges that might benefit your project.
Facilities: Overhead projector, Laptop PC (Windows XP Pro) with CD drive, LCD computer projector. We welcome archiving talks in electronic format if you are willing. Please leave a copy for us (CD-R preferred).
All presentations will be at the Kemp NRS classroom located above the boat house. Note that none of the facilities we will be using are climate controlled – be ready to dress for weather.
Breakfast and lunch are in the dining hall. Food for breakfast (cereals, breads, fruit, milk, juice, coffee), lunch (breads, cheese, peanut butter, salads, fruits, chips, juices) and snacks will be provided. Group dinners will occur most nights at local restaurants. Please let us know if you have any special dietary requests.
Depending on weather and interest, we will schedule an early morning or early evening stable boundary layer bubble release sometime during the meeting, probably at a flux tower site. This is optional for everyone except for A.S. Denning.

What to bring (Lodging information)
Limited (30 beds) dormitory-style accommodations are provided at Kemp Natural Resources Station. Sheets and linens are provided (you can also bring your own sleeping bag). Towels are NOT provided. You may also want to bring shower slippers, hiking shoes, a bathing suit, a flashlight, and some bug spray. We will have access to a large kitchen for group or individual meals. Cooking vessels, utensils, plates and cups are all provided. Food is available at nearby supermarkets. High-speed internet access is provided at the Kemp lab.
As an alternative, you may stay at nearby hotels (all are around 15 minute drive). Click here for a local hotel directory. We recommend the Americinn Motel in Minocqua (National reservations: 1-800-634-3444, Local: 715-356-3730) or the New Concord Inn in Minocqua (1-800-356-8888 or 715-356-1800).
Groceries and Sundries - Trig's in Minocqua, WI is the best nearby 24-hour supermarket and liquor store. It is located on state route 70, 1/4 mile west of the intersection of 70 and US 51. Near Trig's are a bakery/coffee shop, Walmart and Radioshack. Ace Hardware in Woodruff, WI (north of Kemp on state route 47) is the best local hardware store.
Restaurants - Information about the Minocqua area, including restaurants can be found at http://www.minocqua.org/ and at http://www.innline.com/ For local microbrews, check out the Minocqua Brewery in Minocqua off of US-51. Another local tradition is the Friday night fish fry, available at just about any place.
Recreation - Canoes and rowboats are available for use from the Kemp boathouse. From Kemp you can explore the many surrounding lakes. Hiking opportunities are infinite in the Chequamegon-Nicolet National Forest. Trails also exist on the Kemp property. The Upper Peninsula of Michigan, about 1 hour away, has beautiful state parks (i.e., Porcupine State Park). Fishing is also very popular up-here; a Wisconsin non-resident four-day fishing license will set you back about $15.
Other attractions - World's largest wooden penny and the Dr. Kate museum in Woodruff, the Rhinelander Hodag at the Rhinelander Chamber of Commerce, Fred Scheer's lumberjack show in Woodruff. Mini-golf and "wildlife" safaris are also prevalent in the Northwoods.
About the ChEAS research collaboration network laboratory exchange program
Funding is available for short-term (2 weeks to 2 months) exchanges of students and postdoctoral researchers between ChEAS core participant laboratories. The objective of the exchange program is to promote cross-disciplinary research focused on understanding the processes controlling forest-atmosphere exchange of carbon dioxide and water and the response of these processes to climate and land-use change. Candidates will be chosen based on scientific merit of proposed research project as determined by the steering committee and participation by the maximum number of participant labs will be strongly encouraged. Funding for laboratory exchanges includes roundtrip airfare from the home institution and per diem. The host laboratory group is expected to provide temporary housing.
To apply for a 2003 lab exchange send the following
materials to Diane Yoder
(dyoder@meteo.psu.edu):
1. statement of research problem
2. proposed work
3. benefits to you, ChEAS, and host lab
4. expected products
5. letter of support from host lab
