About the meeting

Chequamegon Ecosystem Atmosphere Study (ChEAS) Annual Research Meeting
Dates: June 23 - June 25, 2004
Location: 203 Green Hall, University of Minnesota - St. Paul Campus, 1530 Cleveland Ave N., St. Paul, MN 55108

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.

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. Limited travel funding is available.

This year’s meeting topics will include:

1) Up-scaling and down-scaling studies
examples: Regional atmospheric CO2 budget studies
        Regional flux modeling using BIOME-BGC or SiB

2) Proposals and plans for new integrative publications/investigations
        examples: Comparisons of atmospheric budgets and model upscaling
        Investigation of links between regional transpiration and regional photosynthesis
        Stand level eddy covariance NEE vs. biometric NEP
        Comparisons of Washburn and Park Falls flux towers

3) New projects, results
        examples: Buffalo/Wyoming/UWisc NSF Hydrology project
        USDA-FS “Tier 3” investigations

4) Creation of an integrated ChEAS database.

5) New proposal ideas
        examples: NACP up-scaling/down-scaling workshop concurrent with ChEAS 05.
        Investigations of future gypsy moth impacts on the region.
        ChEAS as a regional intensive for the NACP.
        Preparations for NEON?

6) Suggestions for improving student involvement/collaboration within ChEAS
        example: Initiate monthly virtual group meetings?

Getting to and around the Twin Cities and Where to Stay

Minneapolis/St. Paul Airport (MSP) is served by many airlines and rental car agencies.  The airport is a Northwest Airlines hub.  The meeting will be held at the St. Paul campus of the University of Minnesota, in room 203 of Green Hall, 1530 Cleveland Ave N., St. Paul, MN 55108.  The meeting site is 10 miles (20-25 minute drive) from the airport.  We plan to rent several vans to facilitate travel from the hotel to campus and other events.  Thus, you could skip renting a car and just take a cab to the hotel or campus.

Transit options other than car rental include:
Cab: Around $20
SuperShuttle: around $15, and $7 per additional person, $2 discount for return trip
City bus: Metrotransit, one-way fare is $1.25 / $1.75 (rush hour).  You can get to St Paul campus and/or the Days Inn hotel with one transfer.  Use the trip planner section of the website to get a personalized schedule.

Lodging: There are numerous lodging options in the Twin Cities area.  We have arranged for a group rate of $49/night for June 22-25 at the Days Inn in Roseville, MN.  This hotel is very close to the meeting site and breakfast is included. The hotel is also close to shopping at the Rosedale Mall.  Phone number for reservations is: 651-636-6730.  The block of rooms is reserved under the name "Cheas Workshop" and they will be released on June 15.

Directions from airport to Days Inn, 2550 Cleveland Avenue N., Roseville MN 55113: As you leave the airport, follow signs for MN-55 towards Minneapolis / MN-5 and take the exit for MN-55 Fort Snelling/Minneapolis.  Continue on MN-55 West and then continue onto MN-62 West.  Take MN-62 West ~4 miles to I-35W North.  Travel on I-35W North toward Minneapolis about 10 miles.  Take exit 24 for County Road C.  Turn right/South at the bottom of the exit.  It is 2 blocks to the hotel.

Directions from airport to UMN - St. Paul Campus, 1530 Cleveland Ave N., St. Paul, MN 55108:  As you leave the airport, follow signs for MN-55 towards Minneapolis / MN-5 and take the exit for MN-55 Fort Snelling/Minneapolis.  Continue on MN-55 West and then continue onto MN-62 West.  Take MN-62 West ~4 miles to I-35W North.  Travel on I-35W North toward Minneapolis about 5 miles.  Take the exit for I-94 East towards St. Paul.  Travel 3 miles, cross the Mississippi River and take the left hand exit for MN-280 North.  In less than one mile, take the Energy Park / Kasota Ave exit.  Turn right (east) from the exit ramp onto Energy Park Drive, and then left (north) at the traffic light for Raymond Ave.  Travel north on Raymond.  It becomes Cleveland Ave as you enter campus.  Turn right (east) on Commonwealth Ave and enter the parking lot here on your left (daily rate).  Use this map to get to Green Hall (on upper Buford Circle).  There is also an hourly lot on Buford Circle.

Alternate route (through the city, easier at rush hour, also a good way to get to the airport from campus): As you leave the airport, follow signs for MN-55 toward Minneapolis and MN-5 East - St Paul.  Follow signs for MN-5 / W 7th Ave.  After crossing the river, travel east another 0.5 mile and cross St. Paul Ave on your left.  The next left is Snelling Ave.  Turn left (north) onto Snelling (MN-51).  Travel north on Snelling ~4 miles to I-94.  Continue on Snelling past I-94 for another 2 miles.  Take the (right lane) exit for Como Ave and at the end of the exit ramp, turn left (west) onto Como.  Travel another mile past the State Fairgrounds.  Turn right (north) onto Cleveland Ave N.  Turn right (east) on Commonwealth Ave and enter the parking lot here on your left.  Use this map to get to Green Hall (on upper Buford Circle).  There is also an hourly lot on Buford Circle.

Directions from Days Inn to campus: Cleveland Ave in Roseville and Cleveland Ave in St. Paul do not connect since they are bisected by MN-36 and I-35W.  So from the hotel, turn left onto County Road C and get on I-35W South.  In 1/2 mile take the Cleveland Ave / MN-36 exit (#23B) and follow onto Cleveland Ave another 1.5 miles to Commonwealth Ave.  Turn left (east) onto Commonwealth Ave and enter the parking lot here on your left (daily rate).  Use this map to get to Green Hall (on upper Buford Circle).  There is also an hourly lot on Buford Circle.

Directions to campus from other locations: See http://onestop.umn.edu/Maps/directions-stpaul.html

Directions to Buca di Beppo, 1204 Harmon Place, Mpls, 612-288-0138 from campus/hotel: Take I-35W South 6 miles to Exit 17B and merge onto I-94 West and drive 1 mile.  Take exit 231B Hennepin/Lyndale Ave and follow the signs towards Lyndale Ave  / Hennepin Ave Northbound.  Turn right (north) onto S Lyndale Ave.  Lyndale merges with Hennepin as you enter downtown.  After passing the Walker Art Center and Minneapolis Technical College, turn right onto S 12th St.  Buca's will be on your right in a block at 12th and Harmon Place.  Park on the street or in nearby lots.

Return directions: From 12th St, turn left (north) onto Harmon Place and left (west) in one block onto 11th St S and right (north) in one block to head northbound on Hennepin Ave towards downtown.  Drive through downtown, cross the Mississippi.  Hennepin turns into Larpenteur Ave as you enter St. Paul.  Shortly after crossing MN-280, Larpenteur will intersect Cleveland Ave N.  Turn left onto Cleveland Ave N and then onto I-35W North to get back to the hotel.

Directions to Town Hall Brewery, 1430 Washington Ave South, Mpls, 612-339-8696: Take I-35W South 5 miles to Exit 17C, Washington Ave S.  Turn left from the exit ramp onto Washington Ave S.  The Town Hall is near the intersection of Washington and 15th Ave S/3rd St S, aka Seven Corners.  Park on the street or in a lot.  There is often meter parking down (right/south) 15th Ave S (aka 3rd St S).

Alternate route (faster if from campus): Cleveland Ave intersects Larpenteur north of campus.  Turn west from Cleveland (left from campus, right from hotel) onto Larpenteur, which turns into Hennepin Ave as you enter Minneapolis.  Just before the I-35W entrance on Hennepin, turn left (south) onto 11th Ave SE (aka Johnson St NE).  11th Ave SE turns into 10th Ave SE and becomes the Cedar Ave Bridge/19th Ave S after crossing the Mississippi.  Turn right onto Washington Ave S/15th Ave S.  The Town Hall is near the intersection of 15th Ave S and Washington Ave S.

 

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 2004 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
