LPC physical resources
- In addition to the texts and keys available, we have reference collections
for the identification of various fossil organisms. These collections
are constantly growing. Catalogs are under development.
- A large pollen reference collection of over 3000 slides is available.
This collection has a special emphasis on the North American arctic
and subarctic. A catalogue is not currently available; however contact
us for exchange information.
Macrofossil, Wood and Moss Collection
- The LPC has a small herbarium with an emphasis on treeline and arctic
- A large collection of seeds and fruits of over 3000 specimens is available
for the verification of macrofossils.
- We have a small collection of wood thin sections for the identification
of wood fragments in sediments. A photo collection of wood sections
can also be used for wood identification.
- A collection of mosses, collected and identified by J.C. Ritchie,
is available for the verification of mosses.
- We have a small collection of chironomids from the Arctic, the Yukon, and northern Quebec.
- We are developing reference collections of ostracodes and cladocera.
- For diatom work, we are collaborating closely with Paul Hamilton
of the Canadian Museum of Nature.
Sampling and Coring Equipment
- For the collection of lake and bog sediment cores, we have 4 Livingstone
square-rod samplers, rafts, including a small zodiac, casing, drive
- A Glew mini-corer and maxi-corer, along with dredges are available for the collection of
lake surface sediment samples.
- Standard equipment for the sampling of lake water for geochemistry
and plankton is also available.
Core description and subsampling
- Subsampling and core description are done in the core analysis lab,
which includes a clean hood and equipment for the description, photographing
and sampling of sediment cores.
- The lab is equipped with 2 state-of-the-art Nikon Eclipse 80i bio-research microscopes, with brightfield, Phase contrast and DIC capabilities as well as a digital imaging system with a dedicated PC and Simple PCI Image Processing software.
- The lab is also equipped with a Leitz Diaplan microscope with film camera.
- There is a Leitz Wild M3C a Nikon SMZ1500, SMZ645 and three other stereomicroscopes for macrofossil and tree-ring
- The Department also has a number of microscopes for teaching purposes.
- There is a Ultraspec 2100Pro spectrophotometer and equipment for biogenic silica extraction .
Particle size analyzer
- We are equipped with a MicroTrak S3500 laser particle size analyzer for grain size analysis of lake sediments.
- Magnetic susceptibility serves as non-destructive and efficient method
for correlating core sequences and determining the position of volcanic
ash. Measurements reveal reproducible parallel variations in the concentration
of ferrimagnetic minerals, and therefore the importance of inorganic
materials, from core to core within a lake and thus are invaluable tools
for core correlation. Whole core magnetic susceptibility is measured
on sediment sequences using a Bartington MS2C magnetic susceptibility
meter and core sensor (6 cm internal diameter). The meter provides average
magnetic measurements by scanning on either side of sediment directly
within the loop sensor.
Tree ring analysis and equipment
- We have a tree-ring laboratory with a Acu-rite - Quick Chek system
for the precise measurement of ring sequences.
- Standard programs are available for the analysis of the data.
- At the LPC we have both value-added public and proprietary databases
available for use in student theses, including arctic climate data for
the 1970's -1990's from the PCSP
and pollen data from Canada. See
the data page for further descriptions.
- See the software page for
programs we have developed and to read about some of these databases.
New data and databases that we are developing will be available for
GIS, Software and Compilers
Software for statistical analysis
- S+, (including, S+SPATIALSTATS, S+WAVELETS, S+EnvironStats)
- Specialized software, such as C2, CANOCO, the CEP series, Calibrate,
WAPLS, SYN-TAX, etc.
Software for GIS and spatial analysis
- ArcGIS (including ArcInfo)
- Programming tools include Visual C++,Visual Basic and Fortran compilers
- Graphics software includes Corel and Tilia
- A variety of our own software
are also available
Hardware and Platforms *NEW*
- We now have new state-of-the-art computing faciliites, with 4 workstations and 11 computers, connected to a dedicated LAN
- Linux workstation running Mandriva 2007
- Several PCs running Windows, and some for use with specialized software and hardware
- LaserJet 2100TN laser printer, Lexmark E450dn and colour inkjets
- All computers are networked together and to the laser printer for
ease of file transfer and printing.
- An extensive library is available for identifying
plants and animals found in northern Canada and in lake sediments.
Note that these books must not leave the room.
