Deep Drilling of the Amazon Continental Margin: Cenozoic Climate and Biodiversity; Gravity Tectonics; Microbes, Diagenesis, Gas Hydrates and Fluid Flow

March 24-March 26, 2014 – Buzios, Brazil
Convener: Catherine Rigsby, Cleverson Silva, Paul Baker


The origin of the great biodiversity observed in tropical South America has spurred debate for well over a hundred years (Darwin 1859, Agassiz and Agassiz 1868, Wallace 1878), and it remains one of the foundational problems in modern science. This workshop discussed potential IODP drilling to continuously sample sediment from late-Cenozoic to modern age in the “Foz do Amazonas” basin, including the Amazon Fan, on the equatorial Atlantic continental margin of Brazil.
