Expedition 357 Preliminary Report: Atlantis Massif Serpentinization and Life

International Ocean Discovery Program (IODP) Expedition 357 successfully cored an east–west transect across the southern wall of Atlantis Massif on the western flank of the Mid-Atlantic Ridge to study the links between serpentinization processes and microbial activity in the shallow subsurface of highly altered ultramafic and mafic sequences that have been uplifted to the seafloor along a major detachment fault zone. The primary goals of this expedition were to (1) examine the role of serpentinization in driving hydrothermal systems, sustaining microbial communities, and sequestering carbon; (2) characterize the tectonomagmatic processes that lead to lithospheric heterogeneities and detachment faulting; and (3) assess how abiotic and biotic processes change with variations in rock type and progressive exposure on the seafloor. To accomplish these objectives, we developed a coring and sampling strategy based around the use of seabed rock drills—the first time that such systems have been used in the scientific ocean drilling programs. This technology was chosen in hopes of achieving high recovery of the carbonate cap sequences and intact contact and deformation relationships. The expedition plans also included several engineering developments to assess geochemical parameters during drilling; sample bottom water before and after drilling; supply synthetic tracers during drilling for contamination assessment; gather downhole electrical resistivity and magnetic susceptibility logs for assessing fractures, fluid flow, and extent of serpentinization; and seal boreholes to provide opportunities for future experiments. Seventeen holes were drilled at nine sites across Atlantis Massif, with two sites on the eastern end of the southern wall (Sites M0068 and M0075), three sites in the central section of the southern wall north of the Lost City hydrothermal field (Sites M0069, M0072, and M0076), two sites on the western end (Sites M0071 and M0073), and two sites north of the southern wall in the direction of the central dome of the massif and Integrated Ocean Drilling Program Site U1309 (Sites M0070 and M0074). Use of seabed rock drills enabled collection of more than 57 m of core, with borehole penetration ranging from 1.3 to 16.44 meters below seafloor and core recoveries as high as 75% of total penetration. This high level of recovery of shallow mantle sequences is unprecedented in the history of ocean drilling. The cores recovered along the southern wall of Atlantis Massif have highly heterogeneous lithologies, types of alteration, and degrees of deformation. The ultramafic rocks are dominated by harzburgites with intervals of dunite and minor pyroxenite veins, as well as gabbroic rocks occurring as melt impregnations and veins, all of which provide information about early magmatic processes and the magmatic evolution in the southernmost portion of Atlantis Massif. Dolerite dikes and basaltic rocks represent the latest stage of magmatic activity. Overall, the ultramafic rocks recovered during Expedition 357 revealed a high degree of serpentinization, as well as metasomatic talc-amphibole-chlorite overprinting and local rodingitization. Metasomatism postdates an early phase of serpentinization but predates late-stage intrusion and alteration of dolerite dikes and the extrusion of basalt. The intensity of alteration is generally lower in the gabbroic and doleritic rocks. Chilled margins in dolerite intruded into talc-amphibole-chlorite schists are observed at the most eastern Site M0075. Deformation in Expedition 357 cores is variable and dominated by brecciation and formation of localized shear zones; the degree of carbonate veining was lower than anticipated. All types of variably altered and deformed ultramafic and mafic rocks occur as components in sedimentary breccias and as fault scarp rubble. The sedimentary cap rocks include basaltic breccias with a carbonate sand matrix and/or fossiliferous carbonate. Fresh glass on basaltic components was observed in some of the breccias. The expedition also successfully applied new technologies, namely (1) extensively using an in situ sensor package and water sampling system on the seabed drills for evaluating real-time dissolved oxygen and methane, pH, oxidation-reduction potential, temperature, and conductivity during drilling; (2) deploying a borehole plug system for sealing seabed drill boreholes at four sites to allow access for future sampling; and (3) proving that tracers can be delivered into drilling fluids when using seabed drills. The rock drill sensor packages and water sampling enabled detection of elevated dissolved methane and hydrogen concentrations during and/or after drilling, with “hot spots” of hydrogen observed over Sites M0068–M0072 and methane over Sites M0070–M0072. Shipboard determination of contamination tracer delivery confirmed appropriate sample handling procedures for microbiological and geochemical analyses, which will aid all subsequent microbiological investigations that are part of the science party sampling plans, as well as verify this new tracer delivery technology for seabed drill rigs. Shipboard investigation of biomass density in select samples revealed relatively low and variable cell densities, and enrichment experiments set up shipboard reveal growth. Thus, we anticipate achieving many of the deep biosphere–related objectives of the expedition through continued scientific investigation in the coming years. Finally, although not an objective of the expedition, we were serendipitously able to generate a high-resolution (20 m per pixel) multibeam bathymetry map across the entire Atlantis Massif and the nearby fracture zone, Mid-Atlantic Ridge, and eastern conjugate, taking advantage of weather and operational downtime. This will assist science party members in evaluating and interpreting tectonic and mass-wasting processes at Atlantis Massif

A História da Alimentação: balizas historiográficas

Os M. pretenderam traçar um quadro da História da Alimentação, não como um novo ramo epistemológico da disciplina, mas como um campo em desenvolvimento de práticas e atividades especializadas, incluindo pesquisa, formação, publicações, associações, encontros acadêmicos, etc. Um breve relato das condições em que tal campo se assentou faz-se preceder de um panorama dos estudos de alimentação e temas correia tos, em geral, segundo cinco abardagens Ia biológica, a econômica, a social, a cultural e a filosófica!, assim como da identificação das contribuições mais relevantes da Antropologia, Arqueologia, Sociologia e Geografia. A fim de comentar a multiforme e volumosa bibliografia histórica, foi ela organizada segundo critérios morfológicos. A seguir, alguns tópicos importantes mereceram tratamento à parte: a fome, o alimento e o domínio religioso, as descobertas européias e a difusão mundial de alimentos, gosto e gastronomia.

An Analysis of the Sustainability of the Increasing Consumption of Bolivian and Peruvian Quinoa at University Canteens in Berlin

The THESys Discussion Paper “An Analysis of the Sustainability of the Increasing Consumption of Bolivian and Peruvian Quinoa at University Canteens in Berlin” represents the first report in this series compiled solely by bachelor’s and master’s students. It therefore adds an important new category to the series, one that provides a platform for innovative interdisciplinary research conducted by students. The authors are students at Humboldt-Universität’s Departments of European Ethnology, Geography, Philosophy and Physics, the Thaer-Institute of Agricultural and Horticultural Sciences as well as the School of Economics. They all are or have been members of the so-called Themenklasse Nachhaltigkeit & Globale Gerechtigkeit, (Themenklasse Sustainability & Global Justice), a year-long interdisciplinary study project at IRI THESys for fifteen students who receive a monthly scholarship from the German federal government’s Deutschlandstipendium programme. The scholarships, which reward academic excellence and social engagement, are provided by the Stiftung Humboldt-Universität, with co-funding from the Federal Ministry for Education and Research. The Themenklasse Nachhaltigkeit & Globale Gerechtigkeit has existed since 2013. Since its inception, the students of the Themenklasse have used their one year scholarship period to carry out interdisciplinary group work on questions of sustainability and global justice, under the supervision of IRI THESys scientists. In this work, which has always fallen under the larger topic of “Humboldt’s Footprint”, the students have addressed questions of great societal relevance while using the “cosmos” of their university as an area or object of study. Their work has included projects on subjects such as the sustainability of the Humboldt- Universität’s supply chains, student mobility, and official travel at the university’s geography department. The 2016/2017 cohort also decided to focus on Humboldt’s Footprint, this time addressing the question of sustainable food production and consumption. The students began by exploring and comparing different disciplinary approaches to the question of sustainability in a resource context. After determining the major differences in disciplinary approaches and perspectives, they then narrowed down the often broader, more general questions to the specific question of Quinoa consumption in university canteens. During many long meetings and discussions, and with only brief inputs from their supervisors, the students explored the multi-faceted problem of how to assess Quinoa as a product, including its production, transport and consumption. They took approaches to this question of sustainable quinoa consumption that ranged from empirical quantitative work to a normative approach. This report presents an initial summary and synthesis of the outcomes of this work. It is not a final report, as the work of the 2017/2018 cohort will continue to examine this topic. In a June 2017 workshop, the group presented their work to fellow students and explored how this topic could be further refined and developed, e.g. to regionally differentiate the economic and social impacts of the diffusion of quinoa production. As the supervisors of this work, we are excited to learn about the next group of new ideas and to see the outcomes of the next steps in this analysis. We therefore want to express our gratitude to Stiftung Humboldt-Universität for their constant support, which has been essential to ensuring the continuity of the work of this group of talented and enthusiastic young researchers
