Poetry for export : Contemporary Argentine Poetry (1969), de William Shand, una antología poética argentina en inglés

La traducción se planta como el medio para que un público ajeno a la lengua de origen de un texto pueda acceder a él. En el caso de la poesía, debido a su difícil traducción y a su escasa publicación, la problemática de la traducción se torna doble. A partir de entonces, la presentación de una antología poética argentina en inglés como carta de presentación de la literatura nacional en el mundo resulta una obra interesante en cuanto a sus contenidos y repercusiones en el canon internacional

(Table 2) Chemical composition of phosphates from the Namibian and Chilean shelves

This study on phosphorites of different compositions and ages from shelf sediments and seamounts of the Pacific Ocean by means of analytical electron microscopy showed that these phosphorites contain ultra-microscopic inclusions of authigenic minerals and, more rarely, of rare earth element (REE) minerals. In some of phosphorite samples of Pleistocene-Pliocene age from the Namibian shelf both kinds of minerals were found. Uranium minerals were represented by uraninite, coffinite, and ningioite; those of REE - by monazite, xenotime, and bastnesite, which points to their potential accumulation not only as isomorphous admixtures in calcium phosphate but also as independent mineral phases. Coexistence of the minerals noted in shelf phosphorites is caused by repeated changes in redox conditions during formation and then redeposition of phosphate concretions. Presence of uranium minerals in phosphorites from seamounts shows that during an initial step of formation of these phosphorites environment was rather suboxic or reductive than oxic.

Corals, substrate and physical oceanography during the expedition Comau2012, Northern Chilean Patagonia

Cold-water corals provide an important habitat for a rich fauna along the continental margins and slopes. Although these azooxanthellate corals are considered particularly sensitive to ocean acidification, their responses to natural variations in pH and aragonite saturation are largely unknown due to the difficulty of studying their ecology in deep waters. Previous SCUBA investigations have shown an exceptionally shallow population of the cold-water coral Desmophyllum dianthus in near-surface waters of Comau Fjord, a stratified 480 m deep basin in northern Chilean Patagonia with suboxic deep waters. Here, we use a remotely operated vehicle to quantitatively investigate the distribution of D. dianthus and its physico-chemical drivers in so far uncharted naturally acidified waters. Remarkably, D. dianthus was ubiquitous throughout the fjord, but particularly abundant between 20 and 280 m depth in a pH range of 8.4 to 7.4. The persistence of individuals in aragonite-undersaturated waters suggests that present-day D. dianthus in Comau Fjord may show pre-acclimation or pre-adaptation to conditions of ocean acidification predicted to reach over 70% of the known deep-sea coral locations by the end of the century.

Spatial distribution of isotopic compositions of Globigerina bulloides and Neogloboquadrina pachyderma (dex.) and the faunal assemblages of planktic foraminifera in surface sediment samples along the Chilean continental slope between 23°S and 44°S

We report on the spatial distribution of isotopic compositions of the two planktic foraminifera species Globigerina bulloides and Neogloboquadrina pachyderma (dex.), and the faunal assemblages of planktic foraminifera in 91 surface sediment samples along the Chilean continental slope between 23°S and 44°S. Both d13C and d18O data of N. pachyderma (dex.) show little variability in the study area. North of 39°S, the isotopic values of N. pachyderma (dex.) are heavier than those of G. bulloides, whereas south of 39°S, this relation inverses. This is indicative for a change from a well-mixed, deep thermocline caused by coastal upwelling north of 39°S to well-stratified water masses in a non-upwelling environment south of 39°S. In addition, the faunal composition of planktic foraminifera marks this change by transition from an upwelling assemblage north of 39°S to a high-nutrient-non-upwelling assemblage south of 39°S, which is characterized by decreased contributions of upwelling indicators such as G. bulloides, N. pachyderma (sin.), and Globigerinita glutinata. In general, we can conclude that food and light rather than temperature are the primary control of the planktic foraminiferal assemblage between 23°S and 44°S off Chile. Our data point to higher marine productivity at upwelling centers north of 25°S and at 30-33°S. South of 39°S, significant supply of nutrients by fluvial input most likely boosts the productivity.
