Deep-sea mining prospects in French Polynesia: Governance and the politics of time ☆
TL;DR: In this article, the authors present the results of an interdisciplinary expert group review led by the Institute for Development Research and commissioned by the French Polynesian and French governments with the view of reviewing the current state of knowledge on DSM deposits in French Polynesia in order to evaluate the potential for establishing a DSM mining sector, and to make recommendations that could be used as guidelines for developing a policy framework if the exploration and exploitation of DSM resources were to go ahead.

TL;DR: It is suggested that two-thirds of the heat lost from new oceanic lithosphere at the Gal�pagos Rift in the first million years may be vented from thermal springs, predominantly along the axial ridge within the rift valley.

Rare earth elements: critical resources for high technology
Abstract: The rare earth elements (REE) form the largest chemically coherent group in the periodic table. Though generally unfamiliar, the REE are essential for many hundreds of applications. The versatility and specificity of the REE has given them a level of technological, environmental, and economic importance considerably greater than might be expected from their relative obscurity. The United States once was largely self-sufficient in these critical materials, but over the past decade has become dependent upon imports (fig. 1). In 1999 and 2000, more than 90% of REE required by U.S. industry came from deposits in China. Although the 15 naturally occurring REE (table 1; fig. 2) are generally similar in their geochemical properties, their individual abundances in the Earth are by no means equal. In the continental crust and its REE ore deposits, concentrations of the most and least abundant REE typically differ by two to five orders of magnitude (fig. 3). As technological applications of REE have multiplied over the past several decades, demand for several of the less abundant (and formerly quite obscure) REE has increased dramatically. The diverse nuclear, metallurgical, chemical, catalytic, electrical, magnetic, and optical properties of the REE have led to an ever increasing variety of applications. These uses range from mundane (lighter flints, glass polishing) to high-tech (phosphors, lasers, magnets, batteries, magnetic refrigeration) to futuristic (hightemperature superconductivity, safe storage and transport of hydrogen for a post-hydrocarbon economy).

Uptake of elements from seawater by ferromanganese crusts: solid-phase associations and seawater speciation
Andrea Koschinsky,James R. Hein +1 more
TL;DR: In this paper, the authors proposed a simple sorption model related to the inorganic speciation of the elements in seawater, as has been proposed in earlier models, in order to determine the host phases of 40 elements.
