Location: Manitoba, Canada Latitude (N): 50.55° Longitude (W): 96.78°
Site notes: There are several limnological and palaeoecological studies in Lake Winnipeg's South Basin, with cores taken at slightly different locations. For simplicity, only one location is given here.

Sites discussed: Lake Winnipeg - South Basin, Lake Winnipeg - North Basin. A short synthesis paper that pulls together a lot of information from many different studies. Presents an explanation for dry conditions between 7,500 and 4,000 yr BP shown in sediments from Lake Winnipeg. (19/05/2012).

DOI: 10.1080/14634980600876039 Site discussed: Lake Winnipeg - South Basin. Multi-core study using short cores that extend to the late nineteenth century AD, and longer cores that extend to about 900 yr BP (thirteenth century AD). Phosophorus increases upcore are attributed to anthropogenic activities in the watershed. Most of the discussion focusses on the upper parts of the cores, dealing mostly with the twentieth century record. (04/04/2009).
