Fieldwork is a cornerstone of research in the Dendro Center. We have Hagloff increment borers, Trephor punch corers, Stihl chainsaws, crosscut saws, We•no•nah canoes, and portage packs. Back on campus, we maintain multiple lab spaces for sample preparation and analysis. We have many microscopes and prefer Leica, specifically those of the low-magnification boom arm stereo-zoom variety. We use Apple Computers, PJK, J2X, the Dendrochronology Program Library, ARSTAN, PCreg, MatLab, R, WinDENDRO, and the Adobe Creative Suite. With financial support from UMN CLA, we recently established a teaching lab with capacity for twenty-five students.
The main hub for our group is the Dendroecology Lab, located in Room 509 of the Social Sciences Tower. This space includes four microscopes, a pair of computer workstations, large white boards, a kitchenette, and a great view to the North across the Mississippi River.
R.K. "Wrecks" Adams Measuring Room
Across the hall from the Dendroecology Lab, Social Sciences Tower Room 584 houses two of our group's four traditional tree-ring measurement systems. Each setup includes a Velmex Unislide stage micrometer with a Metronics encoder box connected to an iMac and a microscope. We can't seem to agree on one, so we utilize several different measurement software packages. This room is named for Rex Adams, a long-time dendrochronologist and renowned educator at the Laboratory of Tree-Ring Research in Tucson.
Just around the corner in Social Sciences 514, this space houses an iMac workstation, and another complete Velmex measuring setup, and a space for specimen inventory and preparation.
Our largest research lab, Blegen Hall Room 460 is a short trip across the skyway from the Social Sciences Tower. This space is being re-envisioned, but soon it will house our WinDendro Tree-Ring Imaging System, two microtomes from the Swiss WSL, another complete Velmex measuring setup, and several stereozoom microscopes. The Blegen Lab also has a basic wet lab (fume hood, sink, emergency eye-wash and shower) and large benches for specimen preparation & analysis.
This teaching facility is outfitted with 25 microscopes and an instructional scope with video simulcast to four large-screen monitors around the room. It also has several transmitting light fixed arm microscopes.
Our space in the Rarig Building Room 652 includes a large work surface for the processing and preparation of incoming field collections. The Rarig Lab also has industrial shelving for organizing and storing our collection and a fire-proof cabinet that is used to store our chainsaws and flammable materials.
We are fortunate to have access to facilities at the Regis Center, run by the UMN Department of Art. The Center has more than 155,000 square feet of work space and includes a wood shop, metal shop, CNC center, and small saw mill. The Center's professional staff are an enormously valuable resource who provide safety training and supervision to our staff and students while they are using woodworking equipment.
We presently have two boats: a gel-coated 18' kevlar We•no•nah Champlain canoe named Woodshop I. Voluminous but lightweight and fast on the water, the Woodshop is ideally suited to research cruises and portages in into the Boundary Waters Canoe Area Wilderness. We also have a 16' Royalex We•no•nah Adirondack canoe named Betty that is better suited to rocky river trips.
