Amazon Basin, South America, 1853 (Raster Image)

This layer is a georeferenced raster image of the historic paper map entitled: Map of the valley of the Amazon : to accompany Lt. Herndon's report, drawn by H.C. Elliot. It was published by A. Hoen in 1853. Scale [ca. 1:6,750,000]. Covers the Amazon River Basin, South America. The image inside the map neatline is georeferenced to the surface of the earth and fit to the 'World Mercator' projection. All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as drainage, cities and other human settlements, territorial boundaries, exploration routes of William Lewis Herndon and Lardner Gibbon, shoreline features, and more. Relief shown by hachures. Includes vertical section of route from Callo to Pará. This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection and the Harvard University Library as part of the Open Collections Program at Harvard University project: Organizing Our World: Sponsored Exploration and Scientific Discovery in the Modern Age. Maps selected for the project correspond to various expeditions and represent a range of regions, originators, ground condition dates, scales, and purposes.

Carbon geochemistry of sediments from the Amazon deep sea fan

Sediment cores from the Amazon deep sea fan recovered during R/V Meteor cruise 16-2 show in detail the modern areal distribution of sedimentary organic carbon, stable organic carbon isotopes of the organic matter (OM), as well as variations in the depositional processes. In addition, we studied up to 300 m long drilled sediment records recovered during ODP Leg 155 which allow evaluation of temporal variations on the Amazon fan. Our results reveal new evidence for a very rapid change of fan depositional processes and organic carbon source at times of sea-level change over the middle and lower Amazon fan. To estimate the amount of terrestrial organic carbon stored in sediments from the last glacial in the Amazon fan we used stable organic carbon isotopes of the OM (delta13Corg), organic carbon content (Corg), and age models based on oxygen isotopes, faunal data, and magnetic excursions. Following our results, the organic carbon accumulation on the Amazon deep sea fan is controlled by glacio-eustatic sea-level oscillations. Interglacial sea-level high stand sediments are dominated by marine OM whereas during glacial sea-level low stands terrestrial organic carbon is transported beyond the continental shelf through the Amazon canyon and deposited directly onto the Amazon deep sea fan. Glacial sediments of the Amazon fan stored approximately 73*10**15 g terrestrial Corg in 20,000 years or 3.7*10**12 g terrestrial Corg/yr (equivalent to 7-12% of the riverine organic carbon discharge; assuming constant paleo discharge), which is about the same amount of terrestrial organic carbon as deposited on the Amazon shelf today (3.1*10**12 g terrestrial Corg/yr or 6-10% of the modern riverine organic carbon discharge).

Organic carbon and carbohydrates in waters of the Amazon River, Atlantic Ocean, and Tropical Indian Ocean

A method is presented to study carbohydrate composition of marine objects involved into sedimento- and diagenesis (plankton, particulate matter, benthos, and bottom sediments). Analysis of the carbohydrates is based on consecutive separation of their fractions with different solvents (water, alkali, and acid). Ratios of carbohydrate fractions allows to evaluate lability of carbohydrate complexes. They are also usable as an indicators of biogeochemical processes in the ocean, as well of genesis and degree of transformation of organic matter in bottom sediments and nodules. Similarity in monosaccharide composition is shown for dissolved organic matter and aqueous and alkaline fractions of seston and particulate matter.

'Institutional Shopping' for Natural Resource Management in a Protected Area and Indigenous Territory in the Bolivian Amazon.

Focusing on an overlapping protected area and indigenous territory in the Bolivian Amazon, this article discusses how indigenous people continue to negotiate access to natural resources. Using the theoretical framework of New Institutionalism, ethnographic data from participatory observations, and interviews with Takana indigenous resource users and park management staff, we identified four phases of institutional change. We argue that under the current institutionally pluralistic setting in the overlapping area, indigenous users apply “institutional shopping” to choose, according to their power and knowledge, the most advantageous institutional framework in a situation. Indigenous users strategically employed arguments of conservation, indigeneity, or long-term occupation to legitimize their claims based on the chosen institution. Our results highlight the importance of ideologies and bargaining power in shaping the interaction of individuals and institutions. As a potential application of our research to practice, we suggest that rather than seeing institutional pluralism solely as a threat to successful resource management, the strengths of different frameworks may be combined to build robust institutions from the bottom up that are adapted to the local context. This requires taking into account local informal institutions, such as cultural values and beliefs, and integrating them with conservation priorities through cross-cultural participatory planning.
