Methane-rich fluids arising from organic matter diagenesis in deep sediment layers sustain chemosynthesis-based ecosystems along continental margins. This type of cold seep develops on pockmarks along the Congo margin, where fluids migrate from deep-buried paleo-channels of the Congo River, acting as reservoirs. Similar ecosystems based on shallow methane production occur in the terminal lobes of the present-day Congo deep-sea fan, which is supplied by huge quantities of primarily terrestrial material carried by turbiditic currents along the 800 km channel, and deposited at depths of up to nearly 5000 m. In this paper, we explore the effect of this carbon enrichment of deep-sea sediments on benthic macrofauna, along the prograding lobes fed by the current...

Onshore survey of macrobenthos along the Brittany coast following the Amoco Cadiz oil spill
Provedor de dados: 5
Autores: Hyland, Jeffrey L.
A preliminary ecological survey was conducted along the northern Brittany coast for the purpose of evaluating the initial impact of the Amoco Cadiz oil spill on intertidal macrofaunal communities. Specific objectives were to observe obviously oiled, dead, or moribund organisms on contaminated beaches, and to conduct a limited examination of the structure and composition of benthic communities considered at risk to impact. Results reflecting these objectives are discussed for a variety of habitats.
