of the Puget lobe. Final destruction of the Puget lobe occurred when the ice retreated north of Admiralty Inlet. The sea entered the Puget lowland at this time, allowing the deposition of glacial-marine sediments which now occur as high as 50 m altitude
. These deposits suggest that a significant amount of postglacial isostatic and (or) tectonic deformation has occurred in the Puget lowland since deglaciation.

Glaciation) (ca.25,000 17,000yr B.P.). The later parkland interval is dominated by Picea, Tsuga mertensiana, and Gramineae. It corresponds to the maximum ice advance in the Puget Lowland during the Vashon Stade (Fraser Glaciation) (ca.14,000yr B.P
.). An increase in Pinus contorta pollen between the two tundra parkland intervals suggests a temporary rise in treeline during an unnamed interstade. After 13,500yr B.P., a mixed woodland of subalpine and lowland conifers grew at Davis Lake during a period
of rapid climatic amelioration. In the early Holocene, the prolonged expansion of Pseudotsuga and Alnus woodland suggests dry, temperate conditions similar to those of present rainshadow sites in the Puget Lowland. More-mesic forests of Tsuga heterophylla
, Thuja plicata, and Pseudotsuga, similar to present lowland vegetation, appeared in the late Holocene (ca.5500yr B.P.).
Carbonate deposition in turloughs (seasonal lakes) on the western limestone lowlands of Ireland. II: the sedimentary record
Deposits found in seasonal groundwater-fed lakes (turloughs) on the limestone lowland of Ireland were investigated, and of ninety turloughs surveyed, forty-six contained calcareous deposits known as marl, consisting of more than 60% calcium
The influences of a waste water treatment plant on the macro-invertebrate communities of a lowland river in the Campine (Belgium)
The combined effects of purified and unpurified sewage on the macro-invertebrates of the Witte Nete, a Campine lowland river, have been studied. In ten localities, eight of which were downstream a waste water treatment plant, the benthic fauna

of the interglacial units. The Manitoba non-glacial units are correlated with similar deposits from other parts of the Hudson Bay Lowlands and some conclusions about the Sangamonian climate and paleogeography are drawn.
Kategorizacia zasolenych pôd pre ich zurodnenie v oblasti Podunajskej niziny Categorization of salinized soils with a view to their reclamation within the Danube lowland area
Out of the numerous available factological materials of the Complex Pedological Survey as well as some experience all the salinized soils of the Danube lowland are classified according to both intensity and predisposition to secondary salinization
System propulsion of an Amazonian lowland forest : an outline
The study presents an outline of the systems analysis of the terra firme lowland forest N of Manaus, Brazil. The study deals with the water and element cycles, with litterfall and decomposition, and makes some points of the root-mat zone, the heart
Soil erosion in different Lesotho environments-Rate and sediment sources in Sediment sources, sediment residence time and sediment transfer-Case studies of soil erosion in the Lesotho lowlands.
Inventory of sediment sources and possible storage areas and study of reservoir sediments, in three catchments in the lowland area of western Lesotho.
Mathematical generalization of the regime of underground waters in a part of the East slovakian Lowland by means of regression analysis and Fourier series. (MS).
Krajinné typy Vychodoslovenskej niziny, ich potencial a ochrana. (Landscape types in the East-Slovakian lowland, their potential and protection)
A lowered potential for economic activities occurs in the plain of the East-Slovakian lowland, where a negative phenomenon is both stagnation and accumulation of water flowing to or from precipitation into depressional positions. Removal is possible
Mapping in physical geography, three maps of a formerly glaciated lowland in Developments in physical geography. A tribute to J. I. S. Zonneveld..
Three mapping systems are applied to an area of the North German Lowland, on scale 1: 25 000. The Dutch and German systems fave been developed for geomorphological mapping of those particular countries. The third Polish map is a more general
Saisonnalité et déterminisme du pic de fructification en forêt guyanaise. (Fruiting periodicity and its determinants in a lowland rain forest of French Guiana)
The phenology of flowering and fruiting of trees was studied from June 1980 to the end of March 1982 in the lowland rain forest of Piste Saint Elie, French Guiana. The fruiting peak mostly results, at the species level from the adjustment
Landscape and coast development of a lowland fjord margin following deglaciation, East Greenland
This study covers the late and postglacial development of western Jameson Land, a lowland area in a fjord setting in central East Greenland. The A. presents a new and more detailed geomorphological map and outlines its latest morphological
The timing of alluvial sedimentation and floodplain formation in the lowland humid tropics of Ghana, Sierra Leone and western Kalimantan (Indonesian Borneo)
Temporal patterns in floodplain genesis and alluvial sedimentation in lowlands tropical rain forest zones of Ghana, Sierra Leone and western Kalimantan (Indonesian Borneo) based upon 14C age determinations are described. The AA. propose that periods
of cooler and drier conditions; and (2) may be synchronous during the last 60 ka throughout the African and Asian inner humid lowland tropics.
