De geer moraines

These stringy little moraines are generally assumed to form parallel to the retreating ice front -- but some way up-glacier from the ice edge -- in conditions where the bed material is saturated and where the ice is almost being lifted off the bed in a lake or marine environment. De Geer Moraine Patterns of low profile, parallel ridges, sometimes referred to as "cross valley moraines", or "washboard moraine", but more generally known as "De 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. The De Geer moraine or washboard moraine occur as a type of moraine landscape that consists of a series of separate, narrow ridges trending parallel to a former ice front, and which can form annually. The ridges may be up to 300 m apart and up to 15 m high.

Here, we integrate geospatial mapping, morphometric analyses, stratigraphic investigations and ground‐penetrating radar (GPR) subsurface profiling to characterize De Geer moraines in New Hampshire and De Geer moraine ridges occur in abundance in the coastal zone of northern Sweden, preferentially in areas with proglacial water depths in excess of 150 m at deglaciation. From detailed sedimentologic Based on their morphometry and distribution, these features are interpreted as De Geer moraines that formed during the deglaciation of the LIS. De Geer moraines are widely recognized as products of ice margin retreat in glaciomarine settings, but specific modes of moraine genesis are debated. 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.

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.

From detailed sedimentologic While De Geer moraines are widely recognized as products of ice recession in glaciomarine settings, their formative processes remain debated. Here, we integrate geospatial mapping, morphometric analyses, stratigraphic investigations and ground‐penetrating radar (GPR) subsurface profiling to characterize De Geer moraines in New Hampshire and These ice-flow transverse ridges, sometimes known as De Geer moraines (De Geer 1889), have modest heights and widths and variable lengths. De Geer’s original description of Swedish moraines with these characteristics invoked an annual cycle. Present use of ‘De Geer moraine’ refers to Morphometric analyses indicate that moraines in the Seacoast region are on average 1.2 m tall, 885 m long, 30 m wide, and spaced 98 m apart. 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.
