ON COVER — Three-dimensional block diagram of the northeastern deep-water Gulf of Mexico, showing sea floor bathymetry (in shaded colors from 100 to 3200 m), protraction boundaries, cross section through Rum roho salt system (see Figure 4 in Bouroullec et al., p. 1041), and distribution of fields and pipelines (see Figure 2 in Weimer et al., p. 1000). Four floating production systems are shown. Producing fields are shown by sea-floor manifolds for subsea tiebacks. White circles indicate discoveries that are not producing yet. Note that the nearest floating production system (Independence Hub) was decommissioned in 2016. Figure by James Adson, Renaud Bouroullec, and Paul Weimer.
