“…Nevertheless, the timing of the tempestites is crucial to know to further knowledge on the frequency of the storm events. Kristensen et al (2000) recorded a pollen succession within Ristinge Klint that can be correlated with the Bispingen succession of annually lamination (Miiller, 1974) for time estimation (Fig. 10).…”

Taphonomic analysis of Eemian marine mollusks and barnacles at Ristinge Klint on the island of Langeland (Denmark) provides a distinct record of a temporal succession in preservation states. Four different states of preservation are recognized and related to a decreasing hydrodynamic regime in the depositional setting of the Eemian Baltic Sea. The states show a deepening-upward transition from shallow bay environment towards deeper offshore environment. The depositional setting changed significantly in hydrodynamics about 620 and 1550 years into the Eemian (130,000 to 115,000 years BP), according to biostratigraphic correlation with the varves of the Bispingen succession. The taxonomic composition of the paleofauna supports such a deepening-upward interpretation with a contemporaneous change from brackish water to nearly full marine conditions. The sea bottom was affected by at least one period of oxygen deficiency. The analysis also shows that the preservation of shells varies according to differences in shell structures and life habits. Here we show how these differences should be considered in paleoenvironmental reconstructions based on taphonomic analyses. Taphonomy may play an important role in understanding the hydrodynamic conditions within the Eemian Baltic Sea.

“…They, in turn, are overlain by Weichselian glaciofluvial deposits and tills, and the entire succession has been pushed into repeating thrust slices by late Weichselian ice advances (Kristensen et al 2000). Recent studies of the pollen, benthic foraminifers and ostracodes at Ristinge Klint (Kristensen et al 2000) have provided a detailed palaeoenvironmental and vegetational history of this site during the early Eemian. Pollen chronology shows that the sequence represents almost 3000 years, that is, about the first quarter of Eemian time.…”

A dinoflagellate cyst record with strong Mediterranean/Lusitanian affinities is described from marine deposits of Eemian age (Last Interglacial; Late Pleistocene) at Ristinge Klint, Denmark, revealing new information about the hydrographic evolution of the southwestern Baltic Sea. A revised correlation of the pollen record at Ristinge Klint with that of the annually laminated site at Bispingen in northern Germany provides temporal control. Approximately the first quarter of Eemian time is represented. A marine ingression into a lake took place during the Quercus rise, about 300 years into the interglacial, and is marked by low (< c. 3 psu) salinities at the base of the Cyprina Clay that increased progressively. An abrupt and significant rise in the inflow of warm, saline waters from the North Sea occurred at about 750 years into the interglacial (the Corylus rise), and at about 1900 years into the interglacial, strongly stratified waters developed. Higher in the Cyprina Clay and continuing to its top, at nearly 3000 years into the interglacial, more open-marine waters are indicated, although fully marine conditions were not reached. The dinoflagellate record throughout the Cyprina Clay at Ristinge Klint is therefore one of increasing marine influence. Summer sea-surface temperatures approached, and may have exceeded, 26-28 • C during early Eemian time, indicating temperatures at least 5 • C warmer than at present. These warm conditions persisted to the top of the record at Ristinge Klint. No evidence exists at Ristinge Klint for the influence of Arctic watermasses, and the paucity of cold-water species throughout the section reflects mild winter temperatures in the southwestern Baltic Sea. The new species Spiniferites ristingensis is formally described, and the name Operculodinium centrocarpum var. cezare de Vernal, Goyette & Rodrigues, 1989 is validated.

“…The mix of temperate and cold-arctic foraminiferal species implies a mixing of both Atlantic and Arctic water masses during deposition (Kristensen et al, 2000). At the present day, A. beccarii and H. orbiculare environmental conditions (temperature, salinity) vary considerably (Robertson and Mann, 1980;Scott et al, 1980).…”

The seaboard of western Scotland is a classic fjord landscape formed by glaciation over at least the last 0.5 Ma. We examine the glacial geology preserved in the fjords (or sea lochs) of the Summer Isles region of NW Scotland using high-resolution seismic data, multibeam swath bathymetry, sea-bed sediment cores, digital terrain models, aerial photographs, and field investigations. Detailed analyses include seismic facies and lithofacies interpretations; sedimentological and palaeo-environmental analyses; and radiocarbon dating of selected microfauna. Our results indicate that the Pleistocene sediments of the Summer Isles region, on-and offshore, can be subdivided into several lithostratigraphic formations on the basis of seismic character, geomorphology and sedimentology. These are: subglacial tills; ice-distal and glacimarine facies; ice-proximal and ice-contact facies; moraine assemblages; and Holocene basin fill. The submarine landscape is also notable for its large-scale massmovement events -the result of glaciodynamic, paraglacial or seismotectonic processes.Radiocarbon dating of marine shells indicate that deglaciation of this part of NW Scotland was ongoing between 14-13 ka BP -during the Lateglacial Interstadial (Greenland
