Nowadays any investigation of recent marinesediments is carried out with pore water analysis. Their results contribute considerably to the solution of diagenetic and deposite-formation processes of the geological past. (HL).

Schwermineralverteilung und Alter pleistozäner marinerSedimente in Mittelitalien. (Heavy mineral distribution and age of Pleistocene marinesediments in middle Italy)
In the Maremma, Alto Lazio, Middle Italy, heavy mineral studies were used to differentiate several types of beachrock and other marinesediments which are attributed to marine terraces of different age. (L'A.).
A design for a sediment flux sensor is provided for use in sedimentation studies in lacustrine and shallow marine environments. The sensor utilizes an optical system to measure sediment accumulation with a data logger. Unlike other passive
or mechanical sediment trapping systems, the sediment flux sensor records the time of deposition precisely and therefore is useful for investigating the linkages between external processes (hydrological) and sedimentation.
Corrélations entre la sédimentation fluviatile et la sédimentationmarine littorale en Corse. in Colloque AFEQ, Paris 1983. (Relationship between the fluvial sedimentation and the coastal marinesedimentation in Corsica (Western Mediterranean)
On the western coast of Corsica, some sections are described, showing fluvial deposits passing laterally to marine sands and pebbles. In other places, fluvial sediments seem to be simultaneous with a marine regression. The coasts with fluvial
sedimentation during an interglacial (or interstadial) seem to be uplifted areas. In stable or subsident regions, fluvial sedimentation downvalley would be only during glacial or stadial period, with climatic causes. Both cases, eustatic or climatic
This review draws examples from a wide range of marine environments, including estuaries, the intertidal zone, continental shelves and slopes, and the deep sea. It firstly considers sediment stabilisation, slope failure, sediment mixing
, biodeposition, sediment compaction, and hydrodynamic effects. This is followed by a consideration of 2 extremes of the ecological pyramide, the effects of marine meiofauna and marine vertebrates. The central role of faunal mucus and extracellular polymeric

This paper uses statistics to examine some of the problems associated with radiocarbon dating the organic fraction of Antarctic marinesediments and offers some explanations for the observed geographic variability in the age of surface sediments.
To resolve the conflicting terrestrial and marine interpretations, the acoustic and core data collected in 1985 were studied to determine the genesis of the sediment units in the sound. The late Quaternary glacial and paleoceanographic history
