The lake, Nigardsvatn, has been studied since 1968 in order to obtain data on solid material carried by the meltwater stream from the glacier, both in suspension and as bottom load. Between 70 and 85% of the suspended sediment has been deposited
on the lake bottom, forming annual varves. The coarse material has been deposited in a delta, the formation of which started in 1968. Its growth, and hence the volume of total annual bottom load, has been surveyed annually for the past 36 years. In 1969
the entire bottom load was collected by building a fence-like net across the river. If conditions remain constant, the lake will be completely filled in about 500 years.
Abrupt vegetation and climate changes during the last glacial maximum and last termination in the Chilean Lake District : a case study from Canal de la Puntilla (41°S)
Glacial and vegetational history of the Southern Lake District of Chile
This paper reports results from detailed pollen and charcoal analyses of closely spaced Wright square-rod piston cores from a fen in Canal de la Puntilla in the Llanquihue-age moraine belt, about 3 km from the modern lake shore of Lago Llanquihue
near Bahía Octay. This study is based on considerable previous work on the vegetational history of the Chilean Lake District and Isla Grande de Chiloé. Discussion about the warming and cooling events.
Glacial deposition along an ice-contact slope : an example from the southern Lake District, Chile
Glacial and vegetational history of the Southern Lake District of Chile
The AA. investigate the glaciogenic deposits at various topographic settings near the terminal position of low-profile, temperate, piedmont glaciers in the southern Lake District, Chile. Features along lower positions of the slopes include
Paleoecology of the southern Chilean Lake District-Isla Grande de Chiloé during middle-late Llanquihue glaciation and deglaciation
Glacial and vegetational history of the Southern Lake District of Chile
The paleoecological studies of the Southern Lake District-Isla Grande de Chiloé were undertaken to develop from high-resolution reconstruction of late Pleistocene vegetation: 1) presence, associations, and migratory movement of plant taxa; 2
Geomorphology, stratigraphy, and radiocarbon chronology of Llanquihue drift in the area of the southern Lake District, Seno Reloncaví, and Isla Grande de Chiloé, Chile
Glacial and vegetational history of the Southern Lake District of Chile
This paper presents the geomorphology, stratigraphy, and radiocarbon chronology of extensive moraine belts deposited in the region of the southern Chilean Lake District and Seno Reloncaví, as well as on Isla Grande de Chiloé, by Andean piedmont ice
Glacial geomorphologic maps of Llanquihue drift in the area of the southern Lake District, Chile
Glacial and vegetational history of the Southern Lake District of Chile
The AA. present 4 glacial geomorphic maps of Llanquihue drift in the region of the southern Lake District, Seno Reloncaví, and the eastern half of northern Isla Grande de Chiloé, Chile. These maps form the basis of an interdisiplinary research
Glacial and vegetational history of the Southern Lake District of Chile
This paper presents Be 10 exposure ages for 5 different boulders located at 960 m elevation on 2 moraine ridges near Lake Misery at Arthur's Pass, in the Southern Alps of New Zealand. In addition, it gives 2 previously unpublished measurements of Al

The AA. review the different factors that potentially complicate inferences about climate-induced glacier response based on proglacial lake sediments. They discuss each component separately, starting with the climate forcing on the glacier mass
Two well dated Holocene sediment records bordering the Denmark Strait region have been used to reconstruct past climate variability. The content of biogenic silica, clastic and organic material and moss in a lacustrine record from lake N14 has been
