Although the last few years and affordable connectivity. have seen a decline in resource exploration Polar activity has been steadily increasing activities in the Arctic as a result of lower across a variety of industries. With this increased commodities pricing, it is generally accepted that interest comes the question of whether existing the Arctic is poised to be a major site of resource infrastructure can support an ever-growing exploration in the coming years.
