The general features of the surface circulation in the northeastern Gulf are presented from an analysis of surface density distribution and an extensive drift bottle study. Results of drift bottle study are based on 6,400 recoveries. Twenty cruises were conducted in the regions east and south of the Mississippi Delta, during the period September 1960-October 1962. Data obtained at this time indicate a surface flow of approximately 0.7 kt. to the east and northeast during March-June. Hydraulic heads formed by discharge from eastern Passes extend some 70-90 miles seaward. Convergence lines associated with strong density gradients are commonly found along southern boundary of these areas. Surface circulation for the area is depicted as follows: An eastward flow during spring and early summer, which diverges into northeast and southeast flow at varing distances east of the Delta depending on local winds and river discharge; a southwest flow over continental shelf during late summer and fall, which appears to continue westward and into southwestern Gulf. The existence of the southeast flowing loop current also is indicated in the offshore region southeast of the Delta at this time. Flow during winter months is to the southeast and appears to be a result of the northward migration of the loop current. (Author).

A continuing, comprehensive and timely survey of the state of knowledge of ocean science, this distinguished series provides an overview of research frontiers as ocean science progresses. Areas covered include physical, biological, and chemical oceanography, marine geology, and geophysics and the interactions of the oceans with the atmosphere, the solid earth, and ice. Because ocean science is evolving so rapidly, straining the boundaries of traditional sub-disciplines, interdisciplinary topics have a special place in this series--including those topics related to the application of ocean science, for example, to ocean technology, marine operations, and the resources of the sea. As a treatise on advances and new developments, each topical volume starts with fundamentals and covers recent progress, so as to provide a balanced account of how oceanography is evolving. Previous volumes (1-12) in the series are now available from Harvard University Press. In the manifold, multidisciplinary efforts of.

One of the most significant, energetic, yet not well understood, oceanographic features in the Americas is the Gulf of Mexico Loop Current System (LCS), consisting of the Loop Current (LC) and the Loop Current Eddies (LCEs) it sheds. Understanding the dynamics of the LCS is fundamental to understanding the Gulf of Mexico's full oceanographic system, and vice versa. Hurricane intensity, offshore safety, harmful algal blooms, oil spill response, the entire Gulf food chain, shallow water nutrient supply, the fishing industry, tourism, and the Gulf Coast economy are all affected by the position, strength, and structure of the LC and associated eddies. This report recommends a strategy for addressing the key gaps in general understanding of LCS processes, in order to instigate a significant improvement in predicting LC/LCE position, evolving structure, extent, and speed, which will increase overall understanding of Gulf of Mexico circulation and to promote safe oil and gas operations and disaster response in the Gulf of Mexico. This strategy includes advice on how to design a long-term observational campaign and complementary data assimilation and numerical modeling efforts.

For the past several years, a number of research programs have funded significant efforts to advance understanding of and forecasting capabilities for the Gulf of Mexico circulation, including the Loop Current, its associated eddies, and abyssal dynamics. One such program is the National Academies’ Understanding Gulf Ocean Systems initiative, which focuses on improving forecasts of the physical dynamics of the open Gulf of Mexico in space and time scales useful for the reduction of risks to offshore energy exploration and production, as well as for other challenges such as forecasting hurricane intensification and managing fisheries. What has been learned, how can this scientific progress be incorporated into operational models, and what are the remaining gaps in knowledge impeding predictive skill?
