Arctic sea ice can incorporate sediment and associated chemical species during its formation in shallow shelf environments and can also intercept atmospherically transported material during transit. Release of this material in ice ablation areas (e.g. the Fram Strait) enhances fluxes of both sediments and associated species in such areas. We have used a suite of natural (Be, Pb) and anthropogen...

Ongoing advances in laboratory experimental techniques have greatly enhanced the ability to obtained detailed spatiotemporal data for internal waves in challenging regimes. The long-term goal of this research is to use the latest experimental techniques to investigate internal wave dynamics relevant to the Luzon Strait in a custom configured wave tank; and to integrate these results with data o...

pollutions. Recently, both Persian Gulf and Gulf of Oman are experiencing several types of pollution including oil spills and heavy metal pollutions as well as Harmful Algal Bloom (HAB) caused by biological and environmental changes. Theiroccurrence of the red tide or harmful algal bloom during fall and winter 2008-2009 caused numerous unknown factors in the Strait of Hormuz, Persian Gulf and G...

High risk drinking is linked with high rates of physical harm. The reported incidence of alcohol - related trauma among Aboriginal and Torres Strait Islander people in the Northern Territory is the highest in the world. Facial fractures are common among young Aboriginal and Torres Strait Islanders. They are often linked with misuse of alcohol in the Northern Territory and are frequently seconda...

This paper proposes a method for estimating emissions of carbon dioxide (CO2) and particulate matter (PM) from ships using Automatic Identification System (AIS) data. The method can be summarized in three steps : 1) capture of AIS data, 2) estimation of ships resistance, propulsion power, engine power and fuel consumption, 3) estimation of CO2 and PM emissions based on fuel consumption. The met...

During May 1988 a 1230-m ice thickness profile was drilled across a floe in Fram Strait. The probability density function of this data set corresponds closely to extensive ice draft measurements from submarines and the thickness distribution of floes sampled randomly in the area. The observed similarity is attributed to the topography of the pack ice in Fram Strait where each floe is composed o...

We compute S-velocity profiles of the crust across the Messina strait (Italy), the tear zone at the southern end of the Ionian subduction zone. Separating Sicily from Calabria, the Messina Strait hosted some of the strongest earthquakes to ever occur in Italy. Here, the motion of the Ionian slab with respect to Sicily creates a complex tectonic setting characterized by lithospheric tearing. We ...

Bass Strait is an area of shallow continental shelf located between Victoria and Tasmania connecting the south-east Indian Ocean with the Tasman Sea (Figure 1). The region supports a diverse marine ecosystem with a wide range of habitats. The submerged temperate rocky reefs and canyons contain high species biodiversity with a large proportion being endemic to the area [3]. Marine activities of ...

A simplified model of ice-sheet behayiour is described. I t combines the assumptions of rapid ice flow, high viscous actiyation energy and realistic sediment-based sliding dynamics to form a non-linear diffusion-type equation which can display relaxation oscillations analogous to those of surging glaciers, and which may be relevant to large-scale surges of the Hudson Strait and Cabot Strait ice...
