Book Description
Building Ocean Science Partnerships describes a set of potential ocean science projects for cooperative research between scientists from the United States and Mexico, particularly focused on the Pacific Coast of California and Baja California, the Gulf of California, and the Gulf of Mexico. Barriers to cooperation between scientists of the two nations are identified, and methods to overcome such barriers are recommended. The book describes how interactions can be promoted by enhancing opportunities for education and training, building and sharing scientific infrastructure, participating together in large-scale marine research programs and regional ocean observing systems, planning joint science events and publications, and developing sources of binational funding. Building Ocean Science Partnerships will be published in English and Spanish to make its contents widely accessible in the United States and Mexico.
From the Agulhas to the South Atlantic

Book Description
The Agulhas Retroflection transfers heat, salt and vorticity from the Indian Ocean to the South Atlantic. The transfer is accomplished by discrete meso-scale features and by the advection of a water column of mixed Atlantic and Indian Ocean origins. The objectives of this thesis are to measure the strength of the Agulhas-South Atlantic (ASA) exchange and to develop a generalized method for the measurement of mass and thermohaline fluxes. First, ASA mass and energy fluxes are estimated by using sea surface height (SSH) anomalies from satellite altimetry to monitor Agulhas eddies, a significant component of ASA transport. ~20 eddies are tracked from SSH during 1986 - 1989. Six eddies/year are observed entering the South Atlantic; when combined with information from hydrography this suggests minimum annual ASA mass and energy fluxes of O(5x10^6) m^3/s and O(10^17) J. Next, the accuracy of altimetric tide models, critical to measurements of ASA fluxes using altimetry, is evaluated in the Agulhas region by a comparison with in situ bottom pressure (BP). The CSR 3.0 model accounts for 98.5% - 99.4% of the variance in bottom pressure at four locations, with maximum discrepancies between model and in situ tides reaching 6.5 cm. In Enhanced Thermohaline Transport Analysis (ETTA), developed herein, vertically averaged thermohaline transport coefficients are parameterized as functions of SSH and acoustic travel time (tau). These quantities, which can be directly measured, are then used as proxies to determine mass and thermohaline fluxes from time-series of altimetric SSH and tau from inverted echo sounder moorings. Using ETTA, the 1992 - 1993 baroclinic-barotropic ASA fluxes through a moored array at 30S (2E - 17E) are estimated at O(14.5x10^6) m^3/s, O(15x10^20) J and O(83x10^12) kg salt per annum. Meso-scale eddies accomplish at least 18% of the transport. Lastly, ETTA is combined with the Gravest Empirical Mode (GEM) technique to create continuous parameterizations of temperature and salinity fields with pressure, tau and SSH. Thus tau and SSH become proxies for vertically resolved thermohaline profiles. With data from the Caribbean region, GEM-ETTA is shown to have the potential to resolve inter-ocean mass and thermohaline fluxes with time and depth.

Book Description
This handbook is vital for understanding the origin of deep-water sandstones, emphasizing sandy-mass transport deposits (SMTDs) and bottom-current reworked sands (BCRSs) in petroleum reservoirs. This cutting-edge perspective, a pragmatic alternative to the conventional turbidite concepts, is crucial because the turbidite paradigm is built on a dubious foundation without empirical data on sandy turbidity currents in modern oceans. In the absence of evidence for sandy turbidity currents in natural environments, elegant theoretical models and experimental observations of turbidity currents are irrelevant substitutes for explaining the origin of sandy deposits as "turbidites." In documenting modern and ancient SMTDs (sandy slides, sandy slumps, and sandy debrites) and BCRSs (deposits of thermohaline [contour] currents, wind-driven currents, and tidal currents), the author describes and interprets core and outcrop (1:20 to 1:50 scale) from 35 case studies worldwide (which include 32 petroleum reservoirs), totaling more than 10,000 m in cumulative thickness, carried out during the past 36 years (1974-2010). The book dispels myths about the importance of sea level lowstand and provides much-needed clarity on the triggering of sediment failures by earthquakes, meteorite impacts, tsunamis, and cyclones with implications for the distribution of deep-water sandstone petroleum reservoirs. - Promotes pragmatic interpretation of deep-water sands using alternative possibilities - Validates the economic importance of SMTDs and BCRS in deep-water exploration and production - Rich in empirical data and timely new perspectives
