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.

Pollen Collection

  • 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 plants.
  • 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.

Palaeolimnology Collection

  • 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.

Field and Lab Equipment

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 rods, etc.
  • 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 analysis, .
  • 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

  • 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 downloading.

GIS, Software and Compilers

Software for statistical analysis

  • S+, (including, S+SPATIALSTATS, S+WAVELETS, S+EnvironStats)
  • R
  • SAS
  • Specialized software, such as C2, CANOCO, the CEP series, Calibrate, WAPLS, SYN-TAX, etc.
  • Matlab

Software for GIS and spatial analysis

  • ArcGIS (including ArcInfo)
  • Idrisi
  • Variowin
  • Surfer
  • 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
  • Scanner
  • 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.
