Turbidity currents, and other types of submarine sediment density flow, redistribute more sediment across the surface of the Earth than any other sediment flow process, yet their sediment concentration has never been measured directly in the deep ocean. The deposits of these flows are of societal importance as imperfect records of past earthquakes and tsunamogenic landslides and as the reservoir rocks for many deep-water petroleum accumulations. Key future research directions on these flows and their deposits were identified at an informal workshop in September 2013. This contribution summarizes conclusions from that workshop, and engages the wider community in this debate. International efforts are needed for an initiative to monitor and understand a series of test sites where flows occur frequently, which needs coordination to optimize sharing of equipment and interpretation of data. Direct monitoring observations should be combined with cores and seismic data to link flow and deposit character, whilst experimental and numerical models play a key role in understanding field observations. Such an initiative may be timely and feasible, due to recent technological advances in monitoring sensors, moorings, and autonomous data recovery. This is illustrated here by recently collected data from the Squamish River delta, Monterey Canyon, Congo Canyon, and offshore SE Taiwan. A series of other key topics are then highlighted. Theoretical considerations suggest that supercritical flows may often occur on gradients of greater than ∼ 0.6°. Trains of up-slope-migrating bedforms have recently been mapped in a wide range of marine and freshwater settings. They may result from repeated hydraulic jumps in supercritical flows, and dense (greater than approximately 10% volume) near-bed layers may need to be invoked to explain transport of heavy (25 to 1,000 kg) blocks. Future work needs to understand how sediment is transported in these bedforms, the internal structure and preservat

The Hibernia and Terra Nova oilfields, in the Jeanne d'Arc basin, each have several billion barrels of established reserves. The basin's siliciclastic Mesozoic reservoirs exhibit great variations in permeability and degree of faulting and fracturing, as well as a wide variety of oil viscosities. Operational challenges include the need to install subsea facilities in deep holes to escape iceberg scour. Exploration continues both here and in nearby offshore basins such as the Flemish Pass basin.

The Fossil Bluff Grqup (FBG: ?Bathpnian-Albian) is the fill of a forearc basin which lay between the Antarctic Peninsula volcanic arc and an accretionary complex (LeMay Group) to the west (Figs 8.1 and 8.2). Volcanism in the arc, and accretion and deformation in the LeMay Group, were contemporaneous with sedimentation in the forearc basin. The basin was inverted during Late Cretaceous or Tertiary times during an episode of dextral transpressive deformation (Storey and Nell 1988). Tertiary igneous rocks in central and northern Alexander Island reflect arc migration, followed by Neogene extension.
