Greetings. My real name is Paul Dominique Barrette, Ph.D., research scientist at the National Research Council of Canada in Ottawa. I was trained as a geologist and later specialized in ice physics, mechanics and hydraulics. In the last number of years, I have been working on issues of applied nature related namely with ice/winter roads, ice-structure interaction, frazil ice, river ice, and others of a geotechnical nature in cold regions offshore environments. My aim is to bring that material into a form that adheres to the wiki's encyclopedic mandate, in three ways:

1. By extracting only general information from the scientific/engineering literature, while giving precedence to the most recent sources. This includes textbooks and journal articles, but also conference proceedings papers. I try to avoid web sites.
2. I make my own drawings (with Inkscape), and try to keep them as general as possible, simple, self-explanatory and consistent with the article's text. They are based on the literature that was used to write the article and any related background research.
3. My role is that of a messenger. Zero opinion (or almost, since the selection of sources is never fully unbiased).

I began contributing to Wikipedia in 2012. Following are the main articles I have worked on.

• Fast ice
• Finger rafting
• Frazil ice
• Ice
• Jave
• Ice road
• Lead (sea ice)
• Offshore geotechnical engineering
• Pressure ridge (ice)
• Sea ice
• Seabed gouging by ice
• Snow
• Snowflake
• Snow road
• Stamukha
• Strudel (ice)
• Submarine pipeline
• Winter road

•

• 
  When a floating ice sheet (top diagram) is flooded (bottom diagram), a strudel may form, leading to buoyancy-driven, jet-like water drainage and associated scour in the seabed (σ: pressure).
• 
  A simple version of a cone penetrometer, which provides the soil's strength profile.
• 
  Principle of a shear vane, for the determination of the soil's undrained shear strength.
• 
  Submarine pipeline resting on the seabed: a few scenarios.
• 
  Submarine pipeline installation - the pull-tow system.

  Simplistic drawing of compacted snow above a subgrade, used for winter transportation.
• 
  Idealized snowflakes settling into a snow layer.
• 
  The pressures of the water, related with ice buoyancy, upon short-term vertical loading an ice cover. Not to scale — for illustrative purposes only.
• 
  Freeboard on an ice road at different time intervals.
• 
  Ice waves caused by a traveling vehicle - the vertical displacement of the ice surface, vastly exaggerated for illustrative purposes, is indicated as a function of distance to vehicle.
