The geological evolution and sedimentary dynamics of Hout Bay, South Africa
… Bay and to quantify and explain the sediment dynamics of the area. This is important as Hout Bay has the only substantial accumulation of Quaternary sediments on the Atlantic Seaboard of the Cape Peninsula. The Hout Bay study area was saturated with the latest in cutting-edge geophysical …

Sedimentary Dynamics and Water Quality in Floodplains of the Lower Mississippi River near Natchez, Mississippi, during the 2018 and 2019 Floods
… in the main LMR channel, little is known about sedimentary dynamics, water quality, and nutrient concentrations of the overbank water column within the embanked LMR floodplain. These data are needed to support ecological floodplain restoration efforts and provide context for downstream concerns …

ANÁLISE DOS FORAMINÍFEROS RECENTES DA PLATAFORMA CONTINENTAL DE PERNAMBUCO, NE-BRASIL
… slope, relatively warm waters, high salinity and sedimentary cover composed by sediments terrigenous and biogenics. Among the biogenic sediments, the foraminiferal has importance for studies paleoceanographic and paleoecological, because they are predominantly marine and sensitive environmental …

Nearshore Sedimentology of Eroding Microtidal Estuaries: Bon Secour Bay, Alabama and Perdido Bay, Florida
… and qualitative data to better understand sedimentary dynamics associated with contemporary estuarine shoreline erosion in Bon Secour Bay, Alabama and Perdido Bay, Florida. Historical aerial imagery compared with modern imagery indicates an average land loss rate of 0.30 – 0.67 m yr-1 at …

Cenozoic Variations in the Deep Western Boundary Current as Recorded in the Seismic Stratigraphy of Contourite Drifts, Newfoundland Ridge, Offshore Canada
… archive of North Atlantic circulatory and sedimentary dynamics formed under the influence of the Deep Western Boundary Current (DWBC). Seismic-reflection profiles constrained by drill sites from IODP Expedition 342 are used to map the spatial and temporal distribution of contourite …

Sedimentology of the Cape Town boulder beds
… and are essential for reconstructing the ancient sedimentary dynamics along the shoreline in the greater Cape Town region. The cobble- to boulder-size clasts in these fossil beaches point to a genesis that can be linked to the erosion of local rocky shores during hurricanes and “super storms”. …

Paleomagnetic dating of climatic events in Late Quaternary sediments of Lake Baikal (Siberia)
Der Baikalsee ist ein ideales Klimaarchiv für die Mitte Eurasiens. In dieser Arbeit wurde gesteinsmagnetische und paleomagnetische Analysen an hemipelagischen Sequenzen von vier Lokationen analysiert. Die Kerne erreichen ein Alter von maximal 300 ky. In Kombination mit TEM, XRD, XRF und …

Extreme events in geoarchives
… formation during floods by a combined hydro-sedimentary monitoring network at Lake Mondsee spanning from the rain fall to the deposition of detrital sediment at the lake floor. Successions of sub-millimetre to 17 mm thick detrital layers were detected in sub-recent lake sediments of the …

Coastal resilience potential as a coefficient of the coastal erosion risk assessment, and the management of risk areas via nature-based solutions
… by human activities and by local or specific dynamics, which exacerbate its effects, especially in the case of coastal environment conservation. Coastal erosion is a natural process that is exacerbated by climate change and is considered a natural hazard since it threatens the safety of humans …
