This work was begun to determine if fossil foraminifera, preserved in Holocene sediments of the lower River Murray estuary, could be used to discriminate episodes of predominantly euryhaline, estuarine-lagoonal influence from contrasting episodes
Wind and waves: influence of local and non-local waves on mesoscale beach behavior in estuarineenvironments

A 29-day field investigation was conducted on a meso-tidal sand beach in Delaware Bay, New Jersey to document the contribution of local estuarine and non-local ocean waves to beach recovery following storms. Data were gathered on winds, waves, flow

The AA. present radiocarbon ages of sediments underlying and within the Guadalupe dune sheet, where uplift rates are zero or less, indicate that estuarine deposition began locally around 9-11 ka in response to rising sea level. The estuarine

The low terrace of the Seine in the meander of Elbeuf presents three periglacial alluvial deposits and interglacial estuarine formations intercalated, the whole sequence being dated from Saalian. The fauna of great mammals is well represented: among
the bones a coprolite of Hyena has been found in one of interglacial estuarine deposits. (The A.).
Identification of the sources of polycyclic aromatic hydrocarbons on molecular and isotopic characterization from the Yangtze estuarine and nearby coastal areas

Samples of suspended particulate matters (SPMs), surface sediment and road dust were collected from the Yangtze estuarine and nearby coastal areas, coastal rivers, and central Shanghai. The samples were analyzed for the presence of 16 polycyclic

Palynological and geochemical analyses (radiocarbon dates) were used to reconstruct the history of these 2 sites. The results indicate a dynamic past environment, with an overall tendency towards drier conditions. This evidence is supported, in part
, by charcoal analyses indicating an increase in the occurrence of fire over time. Chemical analyses of the sediments indicate that the Bungawalbin site was strongly influenced by estuarine conditions, whereas the Bundjalung National Park site was only
change from estuarine mud to freshwater peat. While the estuarine mud abounds in brackish and marine diatoms, freshwater taxa dominate the peat. This episodic emergence probably contributed to net late Quaternary uplift by negating the kind of submergence

Geomorphic and stratigraphic investigations supported by some radiocarbon datings have permitted to approach a reconstruction of the evolution of Mar Chiquita lagoon. The estuarine body originated during the regressive phase that followed
Quantitative method for the calculation of the environmental impact on the quality of coastal and estuarine waters using the analysis of principal components (PCA) of multivariant statistics

This paper proposes a quantitative method for the calculation of the environmental impact on the quality of coastal and estuarine waters of the Basque Country (Spain). The calculation has been made by means of multivariant statistics, specifically
used. The average environmental impact in coastal and estuarine waters of the Basque Country vary from 25 to 50% in general. Few locations like the Nervión, Deba and ()iartzun estuaries show levels above 50 per cent.
This paper attempts to establish the response of two coastal barriers on the north County Dublin coastline to continued modification of the adjacent estuarineenvironments, over the last two centuries, by urbanisation, reclamation, land drainage

Peaty, tidal-marsh soils interbedded with estuarine mud in late Holocene stratigraphic sequences near Coos Bay, Oregon, may have been submerged and buried during great (M>8) subduction earthquakes, smaller localized earthquakes, or by nontectonic

The purposes of this paper are to identify the processes on estuarine shorelines that affect aeolian transport and dune development and to provide an explanation for the great variety in dune types and their dimensions. Data on dune characteristics

The Mfolozi estuary is a shallow, micro-tidal estuary with average depths of less than 1.5 m during mean flow conditions. The short term observed transitional changes between estuarine and logoonal conditions are ourlined in relation to long term
