The Amazon/Andes of tropical South America is a key region on Earth, and its rainforests host over half of all terrestrial plant species. The forests and their biota have evolved together with the physical landscape, closely linking processes in Earth's interior with climate, surface landscapes, ecosystems, and biodiversity. The Trans-Amazon Drilling Project (TADP) addresses the fundamen…
The socio-ecological system of the Volta Grande do Xingu integrates seasonally flooded forests (igapó), freshwater rapids and indigenous and river dwelling communities. This unique system is under risk of colapse due to severe dewatering promoted by water diversion for hydropower generation (Belo Monte power plant). This condition also emulates the effect of severe climate change droughts…

The Xingu and Tapajós rivers comprise the main hydropower projects planned or under construction in Amazônia. These rivers also stand out due to their specific biodiversity, with emphasis on lithophilic (rocky substrates) and rheophilic (rapids) fishes and endemic birds of flooded areas. Additionally, the Xingu and Tapajós watersheds are hot spots for the expansion of agriculture and past…
Understanding the factors controlling the origin, flux and fate of sediments through space and time is now an objective of the surface processes research. In this context, the Amazon region encompasses the major watershed (7,050,000 km2) of the Earth, forming a continental scale "source to sink" system. The tributaries of the Amazon River drain areas with different bedrock geology, tecton…

The goal of the project is to examine how thermoluminescence (TL) and optically stimulated luminescence (OSL) can be applied to evaluate the natural sensitization processes of quartz in sedimentary systems and soils. With their relationship to thermal events (like burning) and solar exposure (like sediment transport and bioturbation), the TL (peak at 110 ºC) and OSL (fast component) sensi…

The Amazon biome is home to the greatest diversity of species on Earth and is an important element of the carbon cycle, with the capacity to influence the global climate. The Amazon rainforest is crucial for the production and distribution of atmospheric humidity in South America, in addition to sustaining the largest hydrographic basin in the world, which connects the Andean mountains wi…
The Amazon River is responsible for approximately 20% of the freshwater discharge into ocean and is also recognized as an important source of terrigenous sediments to the Atlantic ocean and carbon to the atmosphere as carbon dioxide (CO2) and methane (CH4). Terrestrial or aquatic organic materials are continuously transported, processed and deposited along the Amazon River continuum, whos…
The Atlantic Meridional Overturning Circulation (AMOC) plays a fundamental role in the oceanography and climate of the Atlantic realm. A potential shutdown of the AMOC would cause major changes in surface heat distribution in the Atlantic Ocean, strongly affecting tropical South American precipitation. Thus, a comprehensive understanding of the response of the Atlantic Ocean to changes in…

The generation of biogenic methane (CH4) and carbon dioxide (CO2) in the subsurface of sedimentary basins is a relatively understudied area, but it is crucial for understanding the processes occurring deep underground and their relationship with the global carbon cycle. In this project, we will use samples with a high organic carbon content, obtained from depths up to 924 m during the dri…
Organic materials with upland or water column origins are continuously moved, processed, and deposited along the Amazon River. The organic matter degradation results on CO2 and CH4 production, which may oversaturate the water column or shallow groundwater and consequently diffused to atmosphere. The lower Amazon River is made up of a complicated network of channels that are bordered by fl…
Tropical South American hydroclimate sustains the world's largest biodiversity, as well as hundreds of millions of people. Still, its response to climate change remains highly uncertain. A better understanding of past natural climate variability can be a powerful tool in order to reduce these uncertainties. The Intertropical Converge Zone (ITCZ) is one of the most important atmospheric fe…
The Xingu River is a large clearwater tributary in the eastern Amazon with unique biodiversity and socioeconomic importance. Anthropogenic impacts such as deforestation and hydropower dams building can promote shifts in hydroclimate and sedimentation, affecting ecosystems and carbon cycling. Severe climatic changes are expected to affect the eastern Amazon during the next decades. However…
