There is still a great unawareness about the deep-water circulation in the NE-Central Atlantic since the Late Cretaceous. The morphology, sedimentary stacking pattern and distribution of contourite depositional systems have been widely used as paleoceanographic indicators, given clues about the relative velocity and pathways of bottom currents past-circulation. We present here evidence of a new contourite featu...

During the last decades several works have been carried out on the morphosedimentary processes driven by bottom-currents in several continental margins and abyssal plains worldwide. However these processes still remain poorly understood on deep-water settings and particularly around oceanic islands. This study is focused on the offshore of Madeira Island (Portugal), which is located in the Northeast Atlantic at...
ABSTRACT: The flow of terrestrial groundwater towards the sea is an important natural component of the hydrological cycle (Church, 1996). Hydrological studies have shown that land derived fresh groundwater may discharge through the sea floor through a process known as submarine groundwater discharge (SGD, Taniguchi et al., 2002). Many studies have highlighted the ubiquitous occurrence on the near-shore environm...
