| Using the world's largest data set of in situ ocean current measurements, combined with a high-resolution topography roughness data set, we use a model-assisted hierarchical clustering methodology to estimate the global lee wave generation rate at the ocean floor. Our analysis suggests that internal wave generation contributes 0.750.19 TW (2 standard deviation) to the oceanic energy budget but with a strong dependence on the Brunt-Vaisala (buoyancy) frequency climatology used. This estimate is higher than previous calculations and suggests that internal wave generation may be a much more significant contributor to the global oceanic mechanical energy budget than had previously been assumed. Our results imply that lee wave generation and propagation may be... |

| The progressive evolution of the South Philippine Sea island arc-back-arc complex deduced from drilling on Glomar Challenger Leg 59 places significant restraints upon tectonic processes that may operate in convergent plate boundaries characterized by back-arc spreading systems. As previosuly recognized, remnant arc precursors of the modern Mariana arc and intervening back-arc basins progressively developed from west to east to form the Palau-Kyushu Ridge, the Parece Vela Basin, the West Mariana Ridge, and finally the modern Mariana Trough and Mariana arc. New data suggest that initial periods of back-arc spreading are coincident with minimal arc volcanism rather than major periods of arc volcanism as previously suspected. |

| Delineating the stock structure of highly-mobile, wide-ranging fishes subject to exploitation is a challenging task, yet one that is fundamental to optimal fisheries management. A case in point are stocks of skipjack tuna (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares), bigeye tuna (Thunnus obesus) and albacore tuna (Thunnus alalunga) in the Pacific Ocean, which support important commercial, artisanal, subsistence, and recreational fisheries, and contribute roughly 70 % of global commercial tuna catches. Although some spatial and temporal structuring is recognised within these stocks, growing evidence from a range of approaches suggests that the stock structure of each tuna species is more complex than is currently assumed in both stock assessment... |
