Marsh loss in the Nanticoke estuary dates from the 1920 s. Since 1938 overall rate of loss has averaged 49.6 ha annually, with rates increasing down estuary. Most losses have occurred in submerged upland marshes| tidal freshwater marshes are stable
Stone and gravel contents of arable soils influence estimates of C and N stocks
In this study, relative volumes of stones and gravel were investigated in the top soils, i.e. down to 30 cm depth, of five Swedish arable sites. Bulk density and gravel volume were determined by soil coring and stone volume using the rod penetration
to an overestimation of C and N stocks by 8-9%. It was concluded that the inclusion of stone and gravel volume of arable soils may be important if nutrient stocks of different sites are compared, or the effects of land use changes are scaled up to regional or global
Sedimentology of a late-Pleistocene submarine moraine complex, County Down, Northern Ireland
Three major lithofacies associations found in the Killard Point moraine, County down, Northern Ireland, are attributed to ice-proximal glaciomarine resedimentation of glacigenic debris derived from a partially floating ice-shelf. From
, apron phase and rechannelized phase. Copper-rich, coarse grained deposits were found along channel axes and down the apron flanks. The average thickness of and fraction of the sediment column occupied by turbidities was found to increase with distance
down channel, indicating a down channel decrease in the importance of continuous flow to the channel building process.
that arise from top-down government policy and business strategies, whereas in the case of Singapore, it depends more on the internal factors and the market-driven participation of customers in particular. Policy-makers should give particular consideration
microwave satellite data. The AA. present results based on daily fields of soil temperature, ranging from the soil surface down to 14 m depth. Model results are compared to several long series of soil temperature measurements from Alaska and Siberia
the changes in the glacial system. The results suggest that while the snow and ice volume on the summits appears to be intact, lower elevation glaciers show significant recession and ablation. From 1910 to 2010, West Turgen Glacier receded by c. 600 m and down
-wasted by c. 70 m. This study successively demonstrates the utility of using historic expedition documents to extend the modern record of glacial change.
This paper presents the essence of recent lithostratigraphical studies on a suite of over 250 boreholes drilled in largely unconsolidated Cenozoic sediments between Cape Town and Eland's Bay. Early Pliocene cold-water transgression laid down
the Varswater Formation with its well-known vertebrate fossil assemblage and phosphorite sand. The formation is well developed at Elandsfontyn at elevations up to 89,4 m. The Pleistocene Bredasdorp Formation may be represented by three phases of dune-building
, the oldest dunes being decalcified to silica sand. Evidence of minor marine transgressions of +12, +6 and +2 m is presented.

The 538.8 m deep borehole allowed the palynostratigraphic, paleoecological and paleoclimatological analyses of a rich sporomorpha material. In the Upper Pannonian repeated oscillation was observed together with a process of desalinization of sea
water from the late Upper Pannonian down to Upper Pliocene. (DLO).
Locational shifts in industry occurred within the republic as Belorussia experienced significant development in the post-war period. Intraoblast industrial disparities have tended to increase as industrialization filtered down the urban hierarchy
