Landforms in Skåne, South Sweden - JStor

Using airborne Light Detection and Ranging (LiDAR) data, we have mapped DGMs over the entire country, and we show that they occur predominantly in two distinct areas: in south-central Sweden north of the Middle Swedish end-moraine zone and in northeast … 2014-08-26 De Geer- moraines found on topographic lows tend to have an interconnected concave form, while over or close to elevated areas; they’re slightly convex. The mean distance between prominent ridges showed a connection to the average retreat rate of the last ice, which suggests that prominent ridges had been formed annually. De Geer moraines almost certainly formed at a marine margin. Reaching altitudes of 55 m above present OD, these landforms may provide one of the highest geomorphological All De Geer moraines of any demarcated group of ridges were deposited almost simultaneously during a quiescent phase of ice flow, as the ice subsided into a water‑soaked subglacial layer of till. The basal crevasses, formed during the previous quick flow of the ice mass, were filled by material resembling ground moraine being squeezed up from both sides into the cavity. de Geer moraine.

The results of this study indicate De Geer moraine formation in New Hampshire was likely driven by annual oscillations of the LIS margin in a tidewater setting. De Geer moraines (DGMs) were first identified in Sweden by Gerard De Geer in 1889 and have been mapped since then in many parts of Sweden. Using airborne Light Detection and Ranging (LiDAR) data, we have mapped DGMs over the entire country, and we show that they occur predominantly in two distinct areas: in south-central Sweden north of the Based on a total of 563 moraine ridges recorded in the present dataset from four primary study sites, De Geer moraines were found to be typically 50–300 m long, 10–20 m wide, 0.5–2 m high and individual ridges covering areas of 500–6000 m 2, with considerable inter- and intrasite variability.

The Tarbat Ness De Geer moraines almost certainly formed at a marine margin. Reaching altitudes of 55 m above present OD, these landforms may provide one of the highest geomorphological indicators for former relative sea level in mainland Britain. De Geer moraines (DGMs) are small ridges that were formed at the grounding line during ice retreat by glaciers whose margins terminated in water. They are 22 Oct 2015 De Geer moraines are generally interpreted as being constructed during winter standstills or readvance of the ice margin (Bouvier, Johnson, & Individual units within cross-valley De Geer moraine ridges are interpreted by comparison ice-marginal sediment pile and formed De Geer moraines.

Paleoglaciation on opposite flanks of the Ikh-Turgen - DiVA

Geer moraines", are present over vast areas, in Norway, Sweden, Finland, Maine, Alaska, NWT, Newfoundland, New Brunswick, Saskatchewan, Ontario, Quebec, and other regions; they also occur offshore on the Scotian Shelf. They were first described by Gerard De Geerin 1889, and the landform was named after him in 1959.
