Santos Basin continental shelf morphology, sedimentology, and slope sediment distribution

Autor: Alberto G. Figueiredo Jr., Juliane Castro Carneiro, João Regis dos Santos Filho

Publikováno v: Ocean and Coastal Research, Volume: 71 Supplement 3, Article number: e23007, Published: 21 APR 2023

The ocean bottom morphology, depth, sediment grain size, sediment sorting, carbonate content, and water depth are used to compose seafloor maps as support for biological studies. Sediments are reworked by waves and currents and accumulate according t

Dinâmica erosiva e progradacional das praias de Atafona e Grussaí (RJ), 1954-2019

Autor: Isabelle Afonso Ramos, Ricardo D. Santos, Alberto G. Figueiredo, Rafael da Silva Nunes, Sérgio Cadena de Vasconcelos

Publikováno v: Revista da ANPEGE. 17:162-182

Os litorais são regiões dinâmicas onde agentes atmosféricos, continentais e marinhos interagem e nem sempre atuam em equilíbrio. Como resultado, processos de recuo, avanço e de estabilidade atuam na costa modificando sua morfologia ao longo do

Publikováno v: Anuário do Instituto de Geociências - UFRJ. 41:413-426

This study aimed to identify Holocene paleoenvironmental changes in Guanabara Bay through the foraminifera assemblages associated with isotopes A. tepida δ 13 C and A. tepida δ 18 O. Seven absolute datings (C14) at the core BG28 (5.8 m) indicate th

Autor: Meade A. Allison, Gail C. Kineke, Nils E. Asp, Odete Fátima Machado da Silveira, Charles A. Nittrouer, Daniel J. Nowacki, Richard W. Sternberg, Alberto G. Figueiredo, Steven A. Kuehl, Andrea S. Ogston, Pedro Walfir Martins e Souza Filho, Aaron T. Fricke, David J. DeMaster, L. Ercilio C. Faria

Publikováno v: Annual review of marine science. 13

Sediment transfer from land to ocean begins in coastal settings and, for large rivers such as the Amazon, has dramatic impacts over thousands of kilometers covering diverse environmental conditions. In the relatively natural Amazon tidal river, combi

HIGH-RESOLUTION ACOUSTIC MAPPING OF GAS CHARGED SEDIMENTS AND LIVING BENTHIC FORAMINIFERA ASSEMBLAGES FROM THE NE REGION OF THE GUANABARA BAY (RJ, BRAZIL)

Autor: Marco Brito, Egberto Pereira, Alberto G. Figueiredo, Francielli Paula Delavy, Maria Virgínia Alves Martins, Sérgio Bergamaschi, Maria Antonieta da Conceição Rodrigues, Lazaro Laut, Paulo Miranda, René Rodrigues, Maria Clara Machado da Fonseca

Publikováno v: Journal of Sedimentary Environments, Vol 1, Iss 3, Pp 367-392 (2016)

This work was performed in the NE region of the Guanabara Bay, a highly impacted Brazilian coastal system, located in Rio de Janeiro State. It aimed to: i) identify and map the areas with occurrence of gas in the sediment, as well as its acoustic sig

Linked variations in sediment accumulation rates and sea-level in Guanabara Bay, Brazil, over the last 6000years

Autor: Mauro B. de Toledo, Alberto G. Figueiredo, Fabiano Tavares da Silva, José Marcus Godoy, Ricardo D. Santos, Renato Campello Cordeiro, Sérgio Cadena de Vasconcelos

Publikováno v: Palaeogeography, Palaeoclimatology, Palaeoecology. 415:83-90

Variable sediment accumulation rates in cores collected in Guanabara Bay, Rio de Janeiro State, indicate that filling of the bay started before 6000 years ago and that it was not uniform through time. Comparison of these variable sediment accumulatio
