    Description: This is the first volume of a "final report" that summarizes, often in a speculative vein, what I have learned over the past 35 years or so about large-scale, low-frequency ocean currents, primarily with support from the Office of Naval Research (ONR). I was also fortunate to have been partially supported by the National Science Foundation and, during the preparation of this report, by the Clark Foundation. This report is meant to be an informal, occasionally anecdotal, state-of-the-art summary account of the World Ocean Circulation (WOC). Seemingly simple questions about how ocean currents behave, such as where various brands of sea water are coming from and going to, have been exciting and difficult research topics for many years. This report is not remotely about "all" of the WOC, it is simply a set of comments about what I have looked into. I believe that the results in this report, although presented in a personal way, are consistent with community wisdom. The report is intended to be readable by non-specialists who have a basic scientific/technical background, especially in other oceanographic areas or meteorology or physics or the geophysical disciplines, not just by specialists in physical oceanography. Anyone wishing to get spun up on the observational basis for the WOC could use this report and associated reference lists as a starting point. Volume I concentrates on the North Atlantic Ocean although there is preliminary discussion of global features. Highlights of this global summary are a new type of composite schematic picture of the World Ocean Circulation in its "upper layers" (Figure I-I) and new summaries (Figures 1-12, 21,91) of the global "thermohaline" circulation.

    Description: As part of the Semaphore Experiment four Meddies (Mediterranean Water Eddies) were discovered in the Canary Basin and tracked with freely drifting RAFOS floats. An additional Meddy was discovered off Lisbon by Pingree (1995) and also tracked with RAFOS floats. One large and energetic Meddy, discovered 1700 km west of Cape St. Vincent, Portugal, set a distance and speed record as it translated another 1700 km southwestward at 3.9 cm/sec during the 1.5 years. This Meddy traveled 57% of the distance from Cape St. Vincent toward the spot McDowell and Rossby (1978) found a possible Meddy north of the Dominican Republic. Four Meddies collided with tall seamounts which seemed to disrupt the normal swirl velocity perhaps fatally in three cases. One Meddy appeared to bifurcate when it collided with seamounts. This report describes the float trajectories in the Meddies and summarizes the main results.

    Description: The Synoptic Ocean Prediction Experiment (SYNOP) was an ambitious, multi-faceted program focused on the dynamics and predictailty of the Gulf Stream and its recirculations. The moored array component contained the arrays; one just downstream of Cape Hatteras (the "Inlet Array"), one near 68°W (the SYNOP "Central Array") and one near 55°W ("SYNOP East") to which this report is addessed. There were two settings of the SYNOP East array, the first, from fall 1987 to summer 1989, contained 42 current meters on 13 moorings straddling the mean axis of the Stream and extending north and south into the two recirculations. The second extended the southernmost six moorings for an additional two years until summer 1991. Performance was excellent and all instruments but one were recovered.

    Description: "Baroclinic instability as the largest scale of motion participating in the cross frontal oceanic transport process" was the theme of the 25th summer program at G.F.D. Killworth (Cambridge University) reviewed classical baroclinic instability theory, leading up to recent studies in which the distinctive structure of an ocean front is included. Finite amplitude baroclinic instability in the classical model was discussed by Pedlosky (WHOI). Laboratory experiments on baroclinic frontal theory was surveyed by Griffiths (Australian National University). The different kinds of oceanic fronts were surveyed by Joyce (WHOI), and additional observations were supplied by several of the invited staff. The smallest scales of motion relevant to the cross-frontal transfer problem were discussed from the oceanic standpoint by Osborn (Naval Postgraduate School) and from the point of view of laboratory experiments by Ruddick (Dalhousie University), among others.

    Description: This is the second and final volume of a report that describes some of my investigations over the last 35 years or so into low-frequency ocean current structures, a topic which I will call the World Ocean Circulation (WOC). The material presented constitutes my final report to the Office of Naval Research, and their support over the years is deeply appreciated. I was also fortunate to have been partially supported by the National Science Foundation during my career and, for some of the preparation of this report, by the Clark Foundation. Volume I was focused on the North Atlantic Ocean, after a global scale summary. This volume (II) will consider first the Pacific and Indian Oceans, concentrating on interbasin circulations, meridional cells, and mesoscale eddy fields. Then, there is an exceptionaly brief discussion of the Southern Ocean(s) for background only, followed by a global summary. Lately, I have worked intensely on intergyre and interbasin exchanges, including an inter-comparison of some of the properties of the eddy field in the World's Oceans (Schmitz, W.J., Jr., Reo. Geophys.,33,151-173,1995; J. Geophys. Res., 101,16,259-16,271,1996). Volume II contains not only an update of the global picture, but also new representations of the transport structure of various components of the meridional overturning cells for each ocean. In summary, several similarties as well as dissimilarities between different oceans relative to both their general circulation and their mesoscale eddy field are shown to be associated with interbasin exchanges. This report is meant to be an informal, occasionaly anecdotal, state-of-the-art summary account of the World Ocean Circulation. Seemingly simple questions about how ocean currents behave, such as where various brands of sea water are coming from and going to, have been exciting research topics for many years. This report is not remotely about "all" of the WOC, it is simply a set of comments about what I have looked into during the preparation of this document. I do believe that the results in this report, although presented in a personal way, are consistent with community wisdom. The document is intended to be readable by non-specialists who have a basic scientifc/technical background, especially in other oceanographic areas or meteorology or the geophysical disciplines, not only by specialists in physical oceanography.

    Description: The Deep Basin Experiment (DBE) is an international effort and a part of the World Ocean Circulation Experiment with the principal objective of improving our knowledge of the subthermocline circulation. The DBE fieldwork is focussed on the Brazil Basin and this report is concerned with a moored array situated along its southern boundary which was installed in early 1991 to measure the inflow and outflow to the Basin and to investigate the Brazil Current near 30S. This moored array was a joint undertaking by the Institut für Meereskunde of the University of Kiel and the Woods Hole Oceanographic Institution. Moorings were deployed on Meteor Cruise 15, leg 1 and retrieved on Meteor cruise 22, legs 3 and 4. A total of 57 conventional current meters and two Acoustic Doppler Current Profilers were set on 13 moorings with some concentration within the Brazil Current and the Vema Channel. CTDs were taken at each mooring site as well as in between. Some of the recovered instruments were reset in the Hunter Channel, a suspected additional connection between the Argentine Basin and the Brazil Basin. A later report will summarize this data after it is recovered in May 1994.

    Description: A Severe Environment Surface Mooring (SESMOOR) was designed to make long term meteorological and near surface oceanographic measurements in areas where harsh envionmental conditions prevail. SESMOOR was deployed in the North Atlantic Ocean approximately 300 km southeast of Halifax, Nova Scotia for 141 days during the winter of 1988-89. Meterological data were acquired from two Vector Averaging Wind Recorders (VAWR) located on top of a specially designed buoy mast and included air temperature, relative humidity, barometric pressure, wind velocity, solar and longwave radiation. Sea surface temperature was also acquired by the VAWR. Current velocities and sea temperatures were obtained from two Vector Measuring Current Meters (VMCM) at 20 and 50 meters below the sea surface. This report discusses instrument performance, data quality, pre-and post-deployment calibrations, data telemetry, data processing procedures. This report also presents the data in a variety of displays.

    Description: In 2001, the Geophysical Fluid Dynamics Summer Study Program grappled with Conceptual Models of the Climate. Eli Tziperman (Weizman Institute), Paola Cessi (Scripps Institution of Oceanography) and Ray Pierre- Humbert (University of Chicago) provided the principal lectures. This introduction gave us all a glimpse into the complex problem of the climate, both in the present, past and future, and even on other planets. As always, the next weeks of the program were filled with many seminars from the visitors, and culminated in the fellow's reports.

    Description: This data report summarzes 45 surface drifter trajectories collected between November 1998 and June 2000 as part of the North Brazil Current (NBC) Rings Experiment. NBC rings have been proposed as one of several important mechanisms for the transport of South Atlantic upper-ocean water across the equatorial-tropical gyre boundary and into the North Atlantic subtropical gyre. Such transport is required to complete the meridional overturning cell in the Atlantic forced by the high-latitude production and southward export of North Atlantic Deep Water. The goal of this program is to obtain, for the first time, comprehensive observations of the NBC retroflection, the NBC ring formation process, and the physical structure and properties of NBC rings as they translate northwestward along the low-latitude western boundary. A total of 45 drifters were deployed. Twenty-four of these looped anticyclonically within the five rings identified during this experiment. Seven of the looping ring drifters entered the Caribbean, while the rest moved northward along the eastern flank of the Lesser Antiles.
