Geomorphological, geophysical, and geochemical evidence of fluid flow through the seabed

Journal of Geochemical Exploration, 2003
Abstract Historically, seabed fluid flow (especially groundwater expulsion) has been known to man for centuries. However, modern survey systems such as the side-scan sonar, sub-bottom profiler, and, not the least, the multi-beam echo sounder have facilitated mapping of seabed details at all water depths. Focused fluid flow locations on the seabed are

Special Challenges Designing and Installing Pipelines in Asia-Pacific with Emphasis on Seabed Geomorphology, Routing and Span Rectification

Offshore Technology Conference-Asia, 2014
The offshorepipeline market remains a large segment of oil and gas expenditure inAsia-Pacific and is forecast to continue apace. Design and installation ofpipelines in Asia and Australia is generally no more arduous than usual butthere are some distinctive characteristics of the continental margins withinthis region that are not commonly found in other

Complex seabed geomorphology shaped by various oceanographic processes: a case study from the Gippsland Basin, offshore south-eastern Australia

2023
The Gippsland Basin is located in the southeastern continental margin of Australia and hosts a variety of important marine resources. Recent high-resolution seabed mapping reveals that seabed morphology is extremely complex in different regions of the Gippsland Basin (i.e. northern, central and southern regions), ranging from scarps, cyclic step trains,

Seabed geomorphology of the karst estuaries in the Eastern Adriatic Coast (Dalmatia)

2020
During the Last Glacial Maximum (LGM) lowstand, large areas of the Adriatic shelf were exposed. At that time, relative sea level (RSL) was at least 125m lower than present (FAIRBANKS, 1989 ; LAMBECK et al., 2011 ; BENJAMIN et al., 2017). This enabled formation of lakes, river valleys and their floodplains that were subsequently submerged during ...

Seabed geomorphology: mapping Australia’s way to a sustainable ocean economy

Seabed geomorphology describes the shape and evolution of underwater landscapes. These landscapes interact with ocean currents to create diverse marine habitats. Similar to geological maps on land, maps of seabed geomorphology are vital for making informed decisions to support the sustainable growth of our Ocean Economy.As we gather more detailed ...

A modified gas hydrate-geomorphological model for a new discovery of enigmatic craters and seabed mounds in the Central Barents Sea, Norway

Geo-Marine Letters, 2019
Hundreds of newly discovered gas seeps, craters, and mounds are presented from the central Barents Sea, Norway. Where they occur together, the crater-mound pairs have a preferred orientation towards the southeast. According to complex cross-cutting relationships with iceberg ploughmarks, both the craters and mounds formed during deglaciation (ca. 11–13

Grounding‐line dynamics during the last deglaciation of Kveithola, W Barents Sea, as revealed by seabed geomorphology and shallow seismic stratigraphy

Boreas, 2012
A marine geophysical study reveals a complex deglaciation pattern in the Kveithola trough, W Barents Sea. The data set includes multibeam swath bathymetry and sub‐bottom sediment profiler (chirp) data acquired for the whole extent of a palaeo, marine‐terminating ice stream, along with high‐resolution single‐channel seismic data from chosen profiles ...

Geomorphological evolution and seabed sediments distribution in the Kvarner region (NE Adriatic Sea)

2000
Kvarner region (Kvarner sensu lato) is a part of the Adriatic Sea located between the Istrian peninsula and the Vinodol-Velebit coast. Distribution of seabed sediments and the morphogenesis of the region are discussed.
