... petroleum reservoirs. The intertidal zone (Al Qantur lagoon) has received less attention, especially regarding neoichnological investigations. This study addresses this research gap by combining modern sedimentological and neoichnological observations. Three recurring depositional textures are identified...

...Andrew Trafford; Robert Ellwood; Alastair Godfrey; Christopher Minto; Shane Donohue ABSTRACT The application of distributed acoustic sensing (DAS) for shallow marine seismic investigations is assessed, in particular with respect to the collection of seismic surface wave data in an intertidal...

... to both subaqueous inundation and periodic subaerial exposure. We infer that the Tambak mixed vertebrate-invertebrate trace fossil association occurred on channel-margin intertidal flats in a tide-influenced estuarine setting. The occurrence of a moderately diverse avian footprint and foraging trace...

... diversity. We also report the first discovery of reticulated filaments in a photic setting, associated with these stromatolites. The Sheybarah stromatolites occur in the intertidal to shallow subtidal zones along the seaward-facing beach in three depth-dependent growth forms. Their inner layers were formed...

...Anton F.-J. Wroblewski; Jon Schueth Abstract Oxfordian deposits in northern Colorado and Wyoming, USA, preserve proximal, intertidal, clastic, coastal deposits and distal, offshore to nearshore, subtidal bioclastic facies that accumulated during a forced regression of the Jurassic epeiric sea...

... of the present study were to identify all palynomorphs including NPP from the intertidal sediments of the southern Red Sea coast of Saudi Arabia and to determine their sources and environments. Palynomorphs in the intertidal sediments are autochthonous and allochthonous and were sourced from marine...

...Meng Li; Yanli Lei; Tiegang Li; Shuaishuai Dong Abstract This study explored the response to salinity of intertidal foraminiferal assemblages from the Yellow Sea by culturing them for 100 days at six constant salinity levels (17, 22, 27, 32, 37, and 42 psu) in laboratory microcosms with four...

... Copyright © 2019, SEPM (Society for Sedimentary Geology) 2019 Chitons (Polyplacophora) are a diverse and common group of Mollusca. The chiton shell is formed by eight overlapping aragonitic valves. Chitons are found in rocky intertidal environments worldwide, especially in New Zealand where chitons...

... the shell morphology of two adjacent populations, both live collected and death assemblages, of the infaunal, suspension-feeding, intertidal bivalve Leukoma staminea from the well-studied Argyle Creek and Argyle Lagoon locations on San Juan Island, Washington. Individuals in the low-energy lagoon are free...

...Mrinal Kanti Layek; Palash Debnath; Probal Sengupta; Abhijit Mukherjee ABSTRACT A combination of geophysical study including ground penetrating radar (GPR) and vertical electrical sounding (VES) was done to identify different shallow-subsurface depositional features in an intertidal coast...

...Joohee Jo; Kyungsik Choi Abstract: The morphodynamics and hydrodynamics of intertidal dunes were investigated to understand their controls on the stratigraphic architecture of the dunes on the open-coast macrotidal tributary channel and channel bank in the northern Gyeonggi Bay, west coast of Korea...

...Laurent Seuront; Vincent M. P. Bouchet Abstract The motion behaviour of three species of intertidal foraminifera, Ammonia tepida , Cribroelphidium excavatum and Haynesina germanica , was investigated continuously in the laboratory. We first infer the presence of geotactic and phototactic responses...

...FERNANDO M. ARCHUBY; MARIANA ADAMI; JULIETA C. MARTINELLI; SANDRA GORDILLO; GABRIELA M. BORETTO; MARIANO E. MALVÉ Abstract The use of rocky intertidal assemblages in paleoecology and conservation paleobiology studies is limited because these environments have low preservation potential. Here, we...

..., following experimentally induced hypoxia on an intertidal flat in the Scheldt Estuary, The Netherlands. Sediment hypoxia was induced during one experiment in winter and a second in late spring. The foraminiferal assemblages in the upper 0–1 cm of sediment were sampled at two and five months post-hypoxia...

...Andrew D. La Croix; Shahin E. Dashtgard A bstract : Sedimentological, neoichnological, palynological, and geochemical trends from upper subtidal and intertidal positions on channel bars in the lower Fraser River, Canada are synthesized into a single, coherent framework. From these data we define...

... with a geological background question the length of time of decay for DNA in situ . The preservation of DNA when storing foraminifers after sampling has been discussed previously ( Holzmann & Pawlowski, 1996 ), but not its preservation in situ in intertidal conditions. The present experiment is designed...

... Global Positioning System ( GPS ) sites and two tide gauge stations within 250 km of the rupture area. To better constrain vertical coseismic deformation, we measured the upper growth limits of two sessile intertidal organisms, which are controlled by physical conditions, relative to sea level at 25...

... variability of stable carbon isotopes (δ 13 C), total organic carbon (TOC) values and carbon to nitrogen (C/N) ratios in bulk sediments from intertidal environments of Bandon Marsh (Oregon, USA). Living and dead foraminiferal species from 10 stations were analyzed over two successive years in the summer (dry...
