Abstract. Rapid Arctic warming accelerates permafrost thaw, causing an additional release of terrestrial organic matter (OM) into rivers and, ultimately, after transport via deltas and estuaries, to the Arctic Ocean nearshore. The majority of our understanding of nearshore OM dynamics and fate has been developed from freshwater rivers despite the likely impact of highly dynamic estuarine and deltaic environments on the transformation, storage, and age of OM delivered to coastal waters. Here, we studied particulate organic carbon (POC) dynamics in the Lena River delta and compared them with POC

Abstract:
Recent studies of ancient rift basins focus on the tectonosedimentary models, which emphasize the control of tectonics on the distribution and evolution of depositional systems in rift basins, whereas these studies seldom address stratigraphic dominated depositional models. Compared to footwall depositional systems, hanging wall depositional systems are especially underexplored due to their fine-grained, thin-layered, and widely distributed features. We integrated seismic data, cores, and well logs to define the dispersal of hanging wall depositional systems that are related to the fluctuation

The critical analysis of the Gura Văii &ndash; Turnu Severin &ndash; Izvoru B&acirc;rzii Gilbert-type deltas concentrated on the deltaic architecture and the age of the deltaic deposits, referring especially to the conglomeratic sediments considered the proximal foreset unit of the Gilbert-type fan deltas. It reveals the lack of evidences necessary to demonstrate the existence of the three units (foreset, bottomset and topset beds) which define a Gilbert-type delta. Although there are convincing data for its tectonic origin, the homoclinal structure of these deltaic deposits was cons

Investigations of sedimentary sequences in a marginal part of Homelen Basin (M.

A succession of 8 coarsening upward (CU) sequences (4.5---19 m thick) wad studied. Three sequence types are recognized: sequence type A, B and C. The lower part of all sequence types is composed of silty lacustrine flood basin deposits. The upper part of all sequence types is composed of sandy low sinuosity fluvial channel deposits.

Abstract The deltaic morphology of Sagar island is controlled by the river Hugli to the north and the Bay of Bengal to the south. The seasonal (summer and winter) and diurnal (two high tides and two low tides) fluctuations of sea level and the Hugli discharge with a large amount of silt contribute to the formation of the largest island in Ganga delta. Deposition of sand, silt, clay and mud from south to north is also characteristic of this deltaic island. The 12 km shoreline and its sand ridges are deformed by wind and waves. Mangroves in the swamp, some halophytic plants on the sand dunes and

Abstract:
The 47.8 km long Line 9 of the Barcelona Metro is one of Europe’s longest urban metro lines. Its southern section connects the city to the airport, being entirely excavated through soft deltaic deposits, promoting more sustainable mobility by reducing significant road traffic. This study identifies the most accurate method for predicting surface settlements caused by tunnel excavation using ground movement monitoring data. Several methodologies were assessed, with the Mean Absolute Error (MAE) and Mean Relative Error (MRE) calculated to evaluate their performances. The methods considered were

Baldcypress (Taxodium distichum (L.) Rich.) has been used extensively for dendrochronological reconstruction of climate and is a key species in globally important wetlands with complex, poorly understood relationships between hydrological and ecological processes. To better understand ecosystem responses to changing climate and hydrology and to test whether hydrological or climatological variables are most reflected in chronologies, we developed tree-ring chronologies for six stagnant or riverine swamps in the Mississippi River deltaic plain and modeled growth responses to historical hydrology

Abstract:
The Pearl River Delta (PRD, China) has undergone complex geological development within a multi-island faulted basin, shaped by the interplay of regional tectonic movements, Quaternary sea-level fluctuations, and fluvial-marine interactions. Despite a great number of studies on the Holocene sedimentary sequences and spatial differences of lithofacies and environments, scant attention has been paid to the overarching human influence on deltaic evolution and coastline modifications since the Neolithic epoch.

The 40-year mature acreage is located in the Northern Delta Depobelt of the Tertiary Niger delta basin. Most of the easy-to-define structural play types and prospects have been tested. In order to optimize the opportunity and existing production facilities, new plays and deep exploration targets were defined. The application of sequence and seismic stratigraphy principles with biostratigraphic data, resulted in well-defined Lowstand (LST), Transgressive (TST) and Highstand (HST) packages, the related 40.1mya, 42.7mya, 44.4mya and 48mya Sequence Boundaries (SB) and their Environments of Deposit
