A review and comparative basin analysis is being conducted the two largest, cold-climate, unconfined peatlands of the world: Hudson Bay Lowland (HBL) and Western Siberia Plain (WSP). They have strong similarities but also differences. Some of these consist of:wsp15.jpg (635462 忖准)

- Formed on cratons stable since Mesozoic time
- Flat land (for the most part)
- Not affected greatly by orographic effects
- Open to arctic air currents
- Ranging form arctic to cold temperate climatic zones, although located at different latitudes
- Northern drainage
- Glaciated areas, but differently so during the latest Pleistocene
- Peatland differently affected by postglacial isostatic rebound
- Some differences in floristic composition of peatlands
- Basal Holocene peats older in WSP than in HBL by order of 4-6 ka, however similar thickness of peat developed
