Information for Cape Hurd Lake
Cape Hurd Lake, Devon Is, and Depot Point Lake, Cornwallis Is. Cape Hurd Lake is an isolated marine inlet at sea level with anoxic bottom water and a plateau ice cap in its watershed. Putnam (2004) produced a detailed reconstruction of the last 600 yr using varve thickness, LOI, and BSi from surface cores. A longer vibracore (5.6 m) contains laminated sediments interbedded with massive marine units extending ~8000 yr (Saenger, 2002). Depot Point Lake is a nival-fed isolation basin with laminated couplets extending to ~3500 yr (Haas, 2003). Detailed analysis of structure and composition of the laminated sequences will be conducted at both lakes.
