Tininglilik ( also-Tininnilik) is a glacier dammed lake onn the
southern margin of the Sarqardliup Sermia 30 km south of
Jakobshavn Glacier. I first examined this lake during the UMaine
research program on Jakobshavn in 1985. The lake periodically
drains and refills over an approximate 10 year period. The lake
has an area of 43 square kilometers when full and 20 km2 when
empty, each emptying phase releases 2-3 cubic kilometers of
water. The lake is filled mostly by subglacial input derived
from surface melt, much from supraglacial lake drainage, which
makes June and July the main months for refilling. The lake
drainage and refilling in 1993 and 2003 was examined by Furuya
and Wahr (2005). They expanded on the work of Roger Braithwaite
and Henrik Thomsen who had identified five lake drain-fill
cycles from 1945-1983. In discussing this with them in Norway in
1986 I noted that the lake was not yet refilled, three years
after the last drainage. They suggested that the lake had always
filled relatively slowly and
