Raised internal pressure in a distressed submarine increases the risk of bubble formation and decompression illness after submarine escape. The hypothesis that short periods of oxygen breathing before submarine escape would reduce decompression stress was tested, using Doppler-detectable venous gas emboli as a measure. Twelve goats breathed oxygen for 15 min at 0.1 MPa before exposure to a simu...

A “submarine patent” is one whose issuance and publication has been intentionally delayed by its inventor with the hope that firms will independently discover and come to rely on a similar innovation at some later time, at which point the inventor causes his patent to issue and claims infringement. Although submarine patents are harmful to an innovation-led economy, previous research has strugg...

Background: Offshore lifelines ( i.e ., pipelines and cables) are usually vulnerable to seabed deformations induced by earthquake-triggered geohazards, such as submarine landslides, soil liquefaction, tectonic faulting. Since the complete avoidance of all areas characterized offshore geohazards is not always techno-economically feasible, optimal lifeline route selection deemed necessary for saf...

In South Korea, in line with the increasing need for a reliable water supply following continuous increase demand, Smart Water Grid Research Group (SWGRG) was officially launched 2012. With vision of providing welfare at national level, SWGRG incorporated Information and Communications Technology its resource management, built living lab demonstrative operation (SWG). The Block 112 YeongJong Is...

The Cantabrian Fault is a long-lived crustal fault, 320 km long on land and extending more than 150 km seawards within the Bay of Biscay, which separates different geodynamic domains. Due to its sub-vertical dip and late strike slip movement is poorly evidenced in the shelf and it has been traditionally mapped following the strike of the deepest submarine canyon in the north Atlantic (~4.600 m ...

Submarine groundwater (SGD) is one of the most significant pathways for the exchange of groundwater and/or source of nutrients, metals and carbon to the ocean, subsequently cause deleterious impacts on the coastal ecosystems. Microorganisms have been recognized as the important participators in the biogeochemical processes in the SGD. In this study, by utilizing 16S rRNA-based Illumina Miseq se...

an experiment featuring waterhammer in viscoelastic pipes is presented in which the effects of pipe-wall viscoelasticity on waterhammer pressures are investigated. a large-scale pipeline apparatus made of polyvinyl chloride (pvc) at deltares, delft, the netherlands, has been used to carry out waterhammer experiments. tests have been conducted in a reservoir-pipeline-valve system consisting of a...

Wave formation and propagation due to submarine landslides are complex phenomena that may be divided into four parts: Landslide dynamics, energy transfer from landslide motion to water motion, wave propagation in open water, and wave run-up along the shores. This paper focuses on the energy transfer from landslide motion to water motion, i.e. the generation of tsunamis by submarine landslides.
