Abstract Fireballs are infrequently recorded by seismic sensors on the ground. If recorded, they usually reported as one-off events. This study is first bulk analysis of largest single fireball data set, observed Desert Fireball Network (DFN) in Australia period 2014–2019. The DFN typically observes fireballs from cm-m scale impactors. We identified 25 time series Australian National Seismograp...

BACKGROUND Vitamin D homeostasis may play a critical role in glucose metabolism. Little is known on vitamin D deficiency and its association with diabetes in countries of the Arabia Gulf where the population is experiencing a rapid increase in the incidence of diabetes. METHODS In a cross-sectional study of 960 adults enrolled in the first National Nutrition Survey of the State of Kuwait (NNS...

As oil and gas exploration moves into deeper offshore areas, Shallow Water Flow (SWF) from overpressured, unconsolidated/uncemented sands becomes a high profile drilling hazard. Laboratory measurements show that SWF sands have high seismic compressional to shear velocity (Vp/Vs) ratios. Thus, elastic seismic inversion for Vp/Vs provides a quantitative identification of SWF sands, and predrill p...

A high resolution seismic survey was conducted in the Patos Lagoon, southern Brazil, aboard of the research vessel LARUS of the Fundação Universidade Federal do Rio Grande (FURG). Around 400 km of 3.5 kHz seismic profiles were collected, which provided acoustic signals of good penetration depth and resolution. Seismic anomalies, including turbidity and pocket gas, revealed that gas-charged sedi...

n October 1995, a four-day multi channel seismic and bottom sampling survey was conducted aboard the R/V Ewing in the Pacific’s western Woodlark Basin. This site augmentation effort, supported by USSSP, was associated with JOIDES Proposal #447. New data from this survey provide further evidence for active extension on a low-angle (~25) normal fault but do not support a metamorphic core complex ...

APPROACH In July-August 1998 aboard the USNS Bowditch, we collected sediment cores, CTDs and XBTs, 3.5 kHz subbottom profiles, and high-resolution 48-channel seismic profiles. This survey covered as much of the Gulf as possible given the restrictions that reefs, oil fields and territorial limits have on ship operations. The approach was to seismically map Neogene stratigraphy and tie this struc...

The objectives of this task are both to conduct research on seismic hazards, and to provide relevant input on the expected levels of these hazards to other tasks. Other tasks requiring this input include those dealing with inventory, fragility curves, rehabilitation strategies and demonstration projects. The corresponding input is provided in various formats depending on the intended use: eithe...
