Hadal Ecosystem Expedition Takes Off
An international team of researchers is using the unique deepwater Hybrid ROV Nereus, and other advanced technology to explore life in the depths of the Kermadec Trench, which runs northeast from the North Island of New Zealand. The 40-day expedition, which began on April 12th, kicks off an ambitious three-year collaborative effort funded by the National Science Foundation (NSF). The goal of the project, known as Hadal Ecosystem Studies (HADES), is to conduct the first-ever systematic study of life in ocean trenches, comparing it to the neighboring abyssal plain at depths between 3,000 and 6,000 meters. Due to the extreme pressures of these deep-sea environments and the technical challenges involved in reaching them…
Research Drilling Proposals for the Brazilian Equatorial Margin
A NSF-sponsored workshop will be held in the coastal town of Maresias, São Paulo, Brazil, from the 4th to the 6th of February 2014, to discuss, plan and define the conceptual basis for developing an International Ocean Discovery Program (IODP) Drilling Proposal to investigate the Brazilian Equatorial Margin. b) The opening and expansion of the South Atlantic Ocean. The Brazilian Equatorial Margin (BEM) is a passive, stable margin at equatorial latitudes characterized by continuous sedimentary sequences divided among a series of basins. These basins contain a unique record of regional tectonic, biotic, and climatic events from the end of the early Cretaceous to present.
