Abstract. A proposed null hypothesis for fluvial terrace formation is that internally generated or autogenic processes, such as lateral migration and river-bend cutoff, produce variabilities in channel incision that lead to the abandonment of floodplain segments as terraces. Alternatively, fluvial terraces have the potential to record past environmental changes from external forcings that include temporal changes in sea level and hydroclimate. Terraces in the Trinity River valley have been previously characterized as Deweyville groups and interpreted to record episodic cut and fill during late

Abstract Paleoceanographic information from submarine overflows in the vicinity of oceanic gateways is of major importance for resolving the role of ocean circulation in modulating Earth’s climate. Earth system models are currently the favored way to study the impact of gateways on global-scale processes, but studies on overflow-related deposits are more suitable to understand the detailed changes. Such deposits, however, had not yet been documented in outcrop. Here, we present a unique late Miocene contourite channel system from the Rifian Corridor (Morocco) related to the initiation of Medit

Abstract:
AbstractTerrestrial signals in marine sedimentary archives are often used for reconstructing past environments, vegetation and climate, as well as for determining sediment fluxes, pathways, and depositional sites and changes in erosional runoff. It is therefore important to understand the origin, transport, and depositional processes of the various terrestrial sedimentary components in a depositional system. In this chapter, we use examples from southern Africa to show how source-to-sink studies have led to a clearer interpretation of downcore proxy records. Twelve rivers in four river catchment areas of various scales and in distinct climatic settings and geological formations are included in this compilation. We also discuss studies from the current-swept South African east coast, the broad western and southern margins, and investigations from protected marine embayment settings. We consider a large suite of commonly used proxies (plant wax isotopes, elemental composition, and fossil pollen) as well as hydroacoustic surveying techniques (PARASOUND and multibeam bathymetric profiling). Sampling strategies and sample types that may be used in catchment analyses are discussed. Challenges and limitations of the above-mentioned approaches are outlined. In conclusion, we underline the importance of a thorough source-to-sink approach to paleo-environmental reconstructions using terrigenous proxies.

The combined use of ground-penetrating radar and geotechnical testing by CPT in Pays-de-Monts (Vendée, France) effectively characterizes the coastal geosystem. The results reveal the internal structure and soil behavior type of coastal dunes and their underlying sedimentary units, highlighting distinct features beneath the dune system at two neighboring sites. At La Parée Grollier, the dunes migrated above former foreshore and marsh deposits, and the study reveals the sub-surface foreshore-marsh transition. At La Pège, a clay-rich paleo-channel was identified which seems connected to the modern beach/dune system. These findings emphasize the value of subsurface data for effective coastal management considering their specific features.

Abstract:
Reconstructions of past, climates and other applications of global models require specification of landforms arid geomorphic systems as boundary conditions. As general circulation models become more sophisticated and comprehensive and the range of applications for reconstructions grows, there will be an increasing demand for valid geomorphic boundary conditions throughout the Phanerozoic. Geomorphologists have not yet, developed the tools and expertise needed to produce reconstructions, so a major gap in understanding of global change now exists. A strategy to fill that gap is presented here. If geomorphology is the study of the form of the land, and if the form of the land can be described by a set of numbers (digital elevation models), then whither geomorphology? Do we become numericists, mathematicians, and statisticians? If geomorphology is the study of the processes shaping the land, and if the form is completely explained by a set of processes and an initial condition (i.e., landform at some earlier time), then two "knowns," current form and current processes, are essential. But if processes themselves change through time and there is an infinite set, of initial conditions, one set for each point in time, then the job becomes overwhelmingly complex. As the geomorphic community has become painfully aware of the difficulties of deep reconstructions, we have withdrawn into the Quaternary, a period during which many simplifying assumptions can be made which allow solution of geomorphic problems. Hence the Geological Society of America lumps "Quaternary Geology" and "Geomorphology" into one division. We have become so comfortable with the notion that, geomorphology and Quaternary geology are synonymous that we have lost sight of the goals of founders of the science such as William Morris Davis and John Wesley Powell who strove to unearth the landforms of the distant past. Of course there is plenty to keep us busy in the good ol’ Quaternary; but we shouldn't ignore the enormous challenges and opportunities that await those who would reconstruct landforms of earlier times.

Full text
Abstract:
Abstract A quantitative approach to selecting modern-depositional settings analogous to those of the Cretaceous Ferron Sandstone is presented as well as an approach to using these analogs to improve subsurface interpretations. Paleotectonic, paleogeographic, and climatic setting of the U.S. Western Interior are integrated to estimate the size of the Ferron drainage network to be 50,000 km 2(19,000 mi 2). Estimates of flow depths, flow velocities, and channel cross-sectional areas suggest maximum trunk river paleo-discharge was on the order of 50 × 10 9m 3/year (250 × 10 9ft 3/year). Analogous modern examples include moderate-sized rivers that drain active mountain belts like the Po (Italy), Rhône, (France), and Ebro (Spain). Continental-scale systems, such as the Mississippi (U.S.A.), Niger (West Africa), Amazon (South America), and Nile (North Africa) deltas, are not appropriate analogs. Incised-valley systems within the Ferron are comparable in depth (about 30 m [100 ft]) to distributary channels in more continental-scale systems. A key difference is that Ferron valleys are filled with multiple channel deposits, with individual channel fills less than about 9 m (30 ft) deep. The relatively uniform size of distributary channels suggests that Ferron rivers experienced only a few orders of bifurcation as they flowed across the delta plain. Shoreline and delta-front deposits are wave-influenced. Locally, the basal Ferron deltas were fluvial dominated, although these fluvial-dominated lobes may lie on the downdrift side of asymmetric wave-influenced deltas, similar in plan to the Brazos, Ebro, and Rhône deltas, and to the southern St. George lobe of the Danube delta. Sizes and geometries of various depositional bodies in modern deltas better constrain estimates of inter-well heterogeneity in subsurface correlations. Correlations of Ferron core and wireline-log datasets are compared with the more complete stratigraphy documented in outcrop. Although the broad clinoform geometry of strata in these deposits can be recreated from subsurface correlations, specific parasequences could not be reliably correlated using only the subsurface data. The subsurface-to-outcrop comparison demonstrates a risk of over-correlating reservoir compartments (i.e. non-connected bodies) separated by minor flooding shales within complex, offlapping fluvial-deltaic reservoir deposits. The Ferron outcrop data provides a measure of uncertainties in correlation of subsurface analogs.

Abstract:
This chapter provides a brief historical account of the success and limitations of using chemical biomarkers in aquatic ecosystems. It also introduces the general concepts of chemical biomarkers as they relate to global biogeochemical cycling. The application of chemical biomarkers in modern and/or ancient ecosystems is largely a function of the inherent structure and stability of the molecule, as well as the physicochemical environment of the system wherein it exists. In some cases, redox changes in sediments have allowed for greater preservation of biomarker compounds; in well-defined laminated sediments; for example, a strong case can be made for paleo-reconstruction of past organic matter composition sources. However, many of the labile chemical biomarkers may be lost or transformed within minutes to hours of being released from the cell from processes such as bacterial and/or metazoan grazing, cell lysis, and photochemical breakdown. The role of trophic effects versus large-scale physiochemical gradients in preserving or destroying the integrity of chemical biomarkers varies greatly across different ecosystems. These effects are discussed as they relate to aquatic systems such as lakes, estuaries, and oceans.
