This book was released on 1993 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous work using the Huntec Deep-Towed Seismic (DTS) system off New Jersey (1987) identified a thick sequence of late Pleistocene sediments on the outer continental shelf. It was suggested (Milliman et al., 1990) that these sediments were deposited by several major melt events during the late Wisconsin glaciation. The physical nature of the sediments, their stratigraphic relation with acoustic stratigraphy and the fine-scale variations of both reflectors and topographic character, however, can be defined only through sediment coring and closely spaced high-resolution profiling. The purpose of this project was to obtain a series of vibrocores to determine the stratigraphic and sedimentologic character of the sediments and to obtain digital data that would allow us to gain a three-dimensional understanding of the shallow structure on the sedimentary sequences in the area.

This book was released on 2014 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Miocene stratigraphic succession on the middle to outer continental shelf off New Jersey, immediately south of the Hudson Canyon, is examined using high-resolution 2D multichannel seismic (MCS) and log data to evaluate sequence stratigraphic models, aided by results of Integrated Ocean Drilling Program (IODP) Expedition 313. High sedimentation, associated with extensive progradation and aggradation, provides a higher resolution record in this region than elsewhere on the shelf. The study of 29 MCS profiles and 4 gamma-ray logs identified and loop-correlated 14 Miocene sequences. Based on log interpretations, highstand systems tracts are associated with most of these 14 sequences; only 3 (sequences A, C, D) exhibit lowstand and transgressive systems tracts. Topset and foreset deposits on the middle to outer continental shelf are thicker than those on the inner shelf due to pronounced aggradation and progradation. This pattern is attributed to middle to late Miocene deltaic progradation and migration combined with sediment compaction and loading that created the accommodation space for these especially thick shallow-marine deposits. Seismic profiles provide a means of anticipating sedimentary facies based on the vertical and lateral arrangement of reflectors within sequences, even in the absence of geologic samples and wireline log measurements. This study evaluates models of sequence stratigraphic evolution by utilizing high sedimentation rates, gamma-ray logs and seismic profiles available in this area. Sequence A shows the importance of drill site data. Using cores and logs, IODP Exp313 showed the maximum flooding surface is the first major downlap surface within sequence A, implying this interval is dominated by thick highstand deposits. By contrast, the widely cited Exxon model predicts that this and all sequences have thick lowstand units containing multiple flooding surfaces, overlain by comparatively thin highstand deposits. Furthermore, the present study showed not all sequences are alike. Shell-632 gamma-ray data reveals thick lowstand and transgressive strata in sequence D, and thin highstand strata consistent with the Exxon model. In contrast, many other sequences examined here have thin lowstand and transgressive systems tracts either below seismic resolution or absent, and thick highstand systems tracts that agree with the model built on Expedition 313 studies.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes the development and application of geophysical techniques to understand the impact of eustasy on the deposition of shallow-marine stratigraphic sequences at the New Jersey margin ̶ one of the best places to study eustasy in sedimentary records. At this margin, eustasy has been the leading driver for sedimentary processes due to smooth thermal subsidence, continuous sediment supply, and stable tectonic history since the Oligocene. This study analyzes 564 km2 of 3D multi-channel seismic (MCS) data from the research cruise MGL1510 together with the IODP Expedition 313 well data to answer the following questions about the margin evolution: 1) What was the influence of eustatic changes on the shelf sedimentary structure during the late Miocene? 2) What was the impact of well-established orbital parameters on the spatial and temporal variations in processes controlling Miocene stratigraphic sequences? I developed the Geometrical Breakdown Approach (GBA) to systematically identify seismic packages based on their geometrical characteristics. The GBA facilitates an objective analysis of stratal patterns and brings the resolution of sequence stratigraphic analysis up to the resolution of the input seismic data. Implementing GBA to the 3D MCS data has resulted in identification of ~40% more structure within the Miocene sequences than previously determined. The new structural model provides the framework for estimating spatial patterns of petrophysical properties within clinothems, which may act as a heterogeneous conduit barrier system to fluid flow in offshore fresh-water aquifers and hydrocarbon reservoirs. The integrated methodology used in this research results in an unprecedented 3D model that dissects and characterizes the Miocene sedimentary record at a significantly higher resolution (~5 m laterally) than previously achieved (~100s of m). Spectral analysis of the cyclicity of these sediments yields local spectral peaks at a wide range of periods, from 25 Kyr to 2.5 Myr, that correspond to the cyclicity observed in insolation due to changes in the Earth's orbital parameters. The onshore-offshore movements of sequences show a 42% correlation with their contemporary insolation. These findings suggest that even short-period orbitally-driven eustatic changes had a direct impact on the Miocene sedimentary record of the margin.

This book was released on 2007 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our primary objective was to sample shallow stratigraphic targets on the New Jersey middle and outer continental shelf. The goal was to establish the geologic history of sedimentary processes on the New Jersey shelf over the last approximately 50,000 years, particularly focusing on the nature of shelf-edge sedimentary wedges, including the formation and preservation of sand bodies, the paleoclimate associated with outer shelf channel formation and subsequent infilling, cross-shelf transport of sediments at or near lowstand, and the influence on the preserved stratigraphy of large sediment outflows associated with postulated glacial lake collapses during the last deglaciation. By interacting with ONR-funded acoustic programs on the New Jersey shelf, we sought to provide the capability for modeling geoacoustic properties of the shallow seabed in three dimensions. Our original plan called for collecting cores using the AHC-800 (Active Heave Compensation to 800 m) drilling system, which was developed and is operated by the DOSECC (Drilling, Observation and Sampling of the Earth's Continental Crust) consortium. Unfortunately, DOSECC pulled out of the contract just a few months prior to the cruise. After consulting with our sponsors and collaborators, we decided to press on with the cruise using a commercial vibracoring system. This option was attractive for two reasons: (1) we would be able to attempt to core in many more locations (perhaps 10 times as many) than would have been possible with the AHC-800, and (2) with our vast collection of chirp seismic data, we could pinpoint erosional windows that would allow us to sample most of our target strata with shorter cores, avoiding in most locations the difficult-to-recover Holocene sand layer.

Available in PDF, EPUB and Kindle. Book excerpt: Using a sequence stratigraphic framework, I investigated lower Miocene Kirkwood Formation sequences Kw1a and Kw1b in onshore New Jersey coastal plain coreholes and their relationship to their coeval offshore sequences m5.8 and m5.7, respectively, on the New Jersey continental shelf. I used corehole and gamma log data from Ocean Drilling Program Leg 150X Cape May and Leg 174AX Ocean View sites to evaluate the anatomy of sequences Kw1a and Kw1b by identifying gamma log stacking patterns, lithologic changes/stacking patterns, Sr-isotope data, chronostratigraphic data, bioturbation, indurated zones, and stratal surfaces (i.e., maximum flooding surfaces [MFS], transgressive surfaces [TS], and sequence boundaries). At Cape May, I found that Kw1a is a composite sequence containing three higher order sequences (Kw1a1, Kw1a2, and Kw1a3), similar to its counterpart at Ocean View. Sequence m5.8 at Integrated Ocean Drilling Program Expedition 313 Site M27 was reinterpreted by integrating Oc270 line 529 seismic data with core and gamma log data, and two possible interpretations at Site M27 are presented here: 1) m5.8 is a single ~1 Myr scale sequence or 2) m5.8 is a ~1 Myr scale composite sequence containing at least two ~100-400 ka scale higher order sequences. Loop correlationsSeismic-core-well log integration analysis suggest that at the AMCOR 6011 site, sequence m5.8 (Kw1a) is a composite sequence. I integrated seismic, core, and well log data to test the physical correlation between the offshore and onshore sequences in question. I correlated onshore sequences Kw1a and Kw1b using the gamma logs of coastal plain and nearshore sites Cape May, Ocean View, Cape May Zoo, Sea Isle City, Strathmere, Atlantic City, ACOW 1, ACOW 2, and AMCOR 6011. I integrated onshore, nearshore, and offshore core and gamma log data with R/V Cape Hatteras 0698 (CH0698) and R/V Oceanus 270 (Oc270) multichannel seismic (MCS) profile grids and loop correlated seismic sequence boundaries along the seismic profiles and demonstrated that sequences Kw1a and Kw1b physically correlate to m5.8 and m5.7, respectively.

This book was released on 2023-07-26 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequence stratigraphy has become a powerful tool in the basin analysis of the North Sea Basin, and will continue to play an important role in the maximization of the remaining hydrocarbon potential of the region, whilst also supporting the energy transition in carbon capture and storage projects with Jurassic storage units. This Memoir provides a long-awaited, comprehensive documentation of Jurassic to lowermost Cretaceous sequence stratigraphy of the region (UK, Norway, Denmark and adjacent areas). The volume is amply illustrated by numerous well log displays, core images, seismic lines, chronostratigraphic diagrams and outcrop photographs. Individual chapters discuss the historical usage of sequence stratigraphy in the North Sea Jurassic, sequence stratigraphic concepts and models, application in hydrocarbon field development, definition of stratigraphic traps, well sequence interpretation methodology and controls on sequence development. To complete the volume there are further chapters on North Sea Jurassic lithostratigraphy and its relation to sequence stratigraphy, and descriptions of the biozones used to characterize and correlate the sequences.
