Latitudinal variability of preserved sedimentary organic matter along the Peruvian continental margin as inferred from petrographic and geochemical properties
(Elsevier, 2021)
Processes controlling preservation and accumulation of organic matter (OM) in marine sediments are highly sensitive towards both natural and anthropogenic impacts. Thus, the sedimentary OM is considered a key proxy for the ...

Hidrato de gás submarino: natureza, ocorrência e perspectivas para exploração na margem continental brasileira
(Revista Brasileira de Geofísica, 2000)
Hidrato de gás, ou clatrato é um sólido cristalino sendo composto de água e gases de peso molecular pequeno. Os hidratos de metano são abundantes em sedimentos submarinhos nas margens continentais. A distribuição dos ...
Temporal and population trends in human exploited pinnipeds from Tierra del Fuego
(Elsevier Science, 2020-09)
Archaeological sites on the coast of Tierra del Fuego, Argentina, provide a biogeochemical record that can inform us about those ecological dynamics. An abundance of southern fur seal (Arctocephalus australis) and southern ...
Geochemical characterization of the largest upland lake of the Brazilian Amazonia: Impact of provenance and processes
(Elsevier B.V., 2017-12-01)
Lake Tres Irmas (LTI), the largest upland lake in the Brazilian Amazonia, located in Serra dos Carajas, was characterized using multi-elemental and isotope geochemistry (delta 13(C) and delta N-15) to understand the ...
Self-organized criticality in the substorm phenomenon and its relation to localized reconnection in the magnetospheric plasma sheet
(Blackwell Publishing Ltd, 2000)
Evidence is presented that suggests that there is a significant self-organized criticality (SOC) component in the dynamics of substorms in the magnetosphere. We assume that observations of bursty bulk flows, fast flows, ...
Arsenic and fluoride in groundwater of a loessical unconfined aquifer, Córdoba, Argentina
(IOSR Journal International Organization of Scientific Research, 2016-10)
La Colacha basin (Córdoba province, Argentina) is a piedmont rural area where groundwater is used for different activities. The objective of this work is to assess the controls on geochemistry processes in the unconfined ...
