Compostos orgânicos em sedimentos marinhos: uma viagem ao fundo do Oceano Atlântico Norte
The present study investigates the origin and distribution of several classes of organic compounds present in recently deposited abyssal sediments in the North East Atlantic Ocean. Six cores were sampled (multicorer) along 20ºW longitude as part of the UK's Biogeochemical Ocean Flux Study (BOFS...

The present study investigates the origin and distribution of several classes of organic compounds present in recently deposited abyssal sediments in the North East Atlantic Ocean. Six cores were sampled (multicorer) along 20ºW longitude as part of the UK's Biogeochemical Ocean Flux Study (BOFS). The sediments underlie diverse water columns, ranging from the Iceland Basin, an area of high primary productivity but presumed low aeolian inputs, to an area off West Africa characterized by oligotrophic and upwelling waters and high aeolian input.
