2D nonlinear seismic response characteristics of a strait site with deep inhomogeneous soil deposits

Yantu gongcheng xuebao
The strait seabed is usually a deep sediment basin with various types of micro-topographies, and its seismic responses are strongly affected by the micro-topographies. A nonlinear seismic response analysis of 2D refined finite element simulated model for

Wave-induced sloping seabed residual response around a buried pipeline

Most studies of the wave interaction with pipeline were conducted on a flat seabed. This paper presents the results from the numerical modelling simulation to investigate the wave induced response around a half-buried pipeline on a sloping seabed.

Discovery and Fine‐Scale Mapping of Hadal Xenophyophore Habitat in the Nova Canton Trough, Central Pacific Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

Examining the Role of Economic Complexity and Climate Readiness in the Climate‐Fishing Nexus

Sustainable Development, EarlyView.
ABSTRACT This paper investigates the climate‐fisheries association in Gulf Cooperation Council (GCC) nations from 1999 to 2022. A key objective is to explore the role of both the economic complexity index (ECI) and the climate readiness factor (READ) in the climate‐fishing nexus.

Experiment on Dynamic Response of Porewater Pressure in Seabed

PROCEEDINGS OF HYDRAULIC ENGINEERING, 1994
Time series of the porewater pressure in seabed under the action of the changing water pressure was experimentally investigated. Firstly, the response of porewater pressure to an abrupt change of the water pressure at the bed surface was measured. Secondly, a simple impulse-response model was proposed to estimate the time scale of the relaxation of ...

Application research on nonlinear partitioned analysis of soil-structure interaction method of seismic response for seawater-seabed-structure

Scientific Reports
The analysis of seismic response in marine engineering structures is pivotal for guaranteeing their seismic safety. Such analyses are intricate due to the complexity of fluid–structure and soil-structure interactions.

Sustainable seabed mining: guidelines and a new concept for Atlantis II Deep

, 2012
The feasibility of exploiting seabed resources is subject to the engineering solutions, and economic prospects. Due to rising metal prices, predicted mineral scarcities and unequal allocations of resources in the world, vast research programmes on the ...

From Map Follower to Navigator: Archetypes of Environmental Impact Assessment

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Environmental impact assessment (EIA) scholarship is commonly framed as a tension between efficiency and comprehensiveness paradigms. These paradigms describe a persistent tension but cannot explain how EIA operates through it. Drawing on social systems theory, this analysis traces that operation.
