    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: Laboratory, theoretical and numerical research was conducted into the structure and stability of baroclinic non-linear currents in a rotating fluid. A rotating version of the dam-break problem in which a . density current is generated after a barrier has been removed was studied. The speed of the current and its width and depth were measured by Whitehead (1981) and more extensively by Stern, Whitehead, and Lien Hua (1982), who report the experiments and compare the results to theory. Properties of a limiting bore solution for rotation density currents predicted earlier by Stern are incorporated into the above theory to predict the speed of the nose of the current. Experiments are described in which the current width is measured to be in reasonable agreement with the theory. Theoretical studies of the stability of a free isolated baroclinic jet whose free surface in cross-section intersects the water surface at two points by Griffiths, Killworth and Stern (1982) was undertaken. The waves permit the release of both kinetic and potential energy. They can have rapid growth rates, thee-folding time for waves on a current with zero potential vorticity being close to one-half of a rotation period. Experiments with a current of buoyant fluid at the free surface of a lower layer were also conducted. The current was observed to be always unstable. Killworth and Stern (1982) showed that a coastal density current in a rotating system is unstable to downstream wave disturbances when the mean potential vorticity increases towards the (vertically-walled) coast and when the mean current vanishes there. Other new instability modes were also found which do not require the potential vorticity extremum of quasi-geostrophic theory. Paldor, in his Ph.D. thesis, used Rayleigh integral to prove that an unbounded geostrophic front of uniform potential vorticity is stable with respect to small perturbations of arbitrary wavelength. Stern and Paldor (1983) used extremum concepts to analyze large amplitude disturbances in a boundary layer shear flow with an inviscid and longwave theory. It was found that initially weak horizontal convergences were concentrated and amplified in time.

    Description: The primary objective of this publication is to share with a wider audience the valuable information and extensive dialogue that took place amongst over 140 individuals who attended the second in a series of planned workshops on the science and management of coastal landforms in Massachusetts. This workshop took place at the Woods Hole Oceanographic Institution on January 24, 2001. The individuals who attended this workshop are actively engaged in planning, managing, regulating, engineering, educating, and studying coastal landforms and their beneficial functions. This workshop titled, Can Humans & Coastal Landforms Co-exist?’, was a natural follow-up to a previous workshop, Coastal Landform Management in Massachusetts, held at WHOI October 9-10, 1997 (proceedings published as WHOI Technical Report #WHOI-98-16). The workshop had a very practical, applied focus, providing state-of-the-art scientific understanding of coastal landform function, case history management and regulation of human activities proposed on coastal landforms, a multi-faceted mock conservation commission hearing presented by practicing technical consultants and attorneys that involved all attendees acting as regulators in breakout sessions, and, at the conclusion of the workshop, an open discussion on all issues related to the science and management of coastal landforms, including future research needs.
    Description: Funding for these proceedings was provided by WHOI Sea Grant and the NOAA National Sea Grant College Program Office, Department of Commerce, under NOAA Grant No. M10-2, Woods Hole Oceanographic Institution Sea Grant Project No. NA86R60075.

    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: Conference name: North Atlantic Current (NAC) System; 19-20 April 1993, Woods Hole Oceanographic Institution, Woods Hole, MA
    Description: On April 19-20, 1993 a two-day workshop was held at the Woods Hole Oceanographic Institution on "The North Atlantic Current (NAC) System". The workshop, which was sponsored by NSF/NOAA/ONR reflected a growing sense of excitement and interest in the oceanographic community in the NAC system and its role in the large scale circulation of the North Atlantic Ocean and Climate of the adjoining landmasses. The presence of the North Atlantic Current with its warm waters at such high latitudes, and its role in both the wind-driven and thermohaline circulations makes it unique amongst the Western Boundary Currents of the oceans. Being on the one hand part of the wind-driven circulation and on the other hand the upper branch of the "Global Conveyor Belt", the North Atlantic current is indeed an enigma, suggesting fundamental issues about the nature of the coupling between the two 'roles' of the current that will need to be addressed. But it was also clear from the workshop discussions that there remain considerable uncertainty about the basic structure of the NAC. A high level of interest in these questions was evident at the workshop. The lectures, presentations, and the discussion sessions where observational and modelling issues were debated, brought out many ideas for the development and focus of future research of the NAC and surrounding waters. This report is intended to provide not only a synopsis of the lectures, papers, and ideas that were discussed, but also a scientific statement from the workshop reflecting a growing consensus for initiating a coordinated research effort in the region.

    Description: During the period October 1985 to October 1986 a large group of oceanographers collaborated in an intensive field effort called the Gibraltar Experiment. Scientists from Morocco, Spain, France, the United Kingdom, Canada and the United States joined together to obtain an extensive suite of measurements which greatly enlarged the oceanographic data base for the Strait of Gibraltar. Primary experiment goals included obtaining one realization of the annual flow cycle, understanding the dynamical balances of the strait flow, developing strategies for long-term monitoring of the Strait, and increasing knowledge of strait effects on the adjacent ocean. Preliminary results show progress toward each of these four goals.
    Description: Funding was provided by the Office of Naval Research through contract Numbers N00014-82-C-0019, N00014-85-C-0001, and N00014-87-K-0007.

    Description: The Nantucket Shoals Flux Experiment (NSFE79) was conducted across the continental shelf and upper slope south of Nantucket from March, 1979 to April , 1980 to measure the flow of shelf water from the Georges Bank/Gulf of Maine region into the Middle Atlantic Bight. Conceived as a cooperative field experiment involving the Northeast Fisheries Center (NMFS), U.S. Geological Survey (Woods Hole), University of New Hampshire, and the Woods Hole Oceanographic Institution, the experiment contained two principal components, a moored array of current meter and bottom instrumentation deployed at six locations across the shelf and upper slope spanning a depth range from 46 m to 810 m, and a series of 27 hydrographic surveys made along or near the moored array line during the experiment. A basic description of the NSFE79 hydrographic data has been given in Part 1 by Wright (1983). A description of the moored array components and the basic moored array data sets is presented here in Part 2.
    Description: The NEFC participation was supported by the NMFS Marine Resources Monitoring, Assessment, and Prediction (MARt-1AP) Program. The U.S. Bureau of Land Management (BLM) supported the USGS field and analysis component under t~emoranda of Understanding M550-MU6-79, M551-MU8- 24, M551-MU9-4, and M551-MU0-18.
