During the 28-month interval from September 1960 through December 1962, drift bottles were re leased periodically from a stationary platform located 11 nautical miles offshore from Panama City, Florida. Of the 951 bottles released, 276, or 29% were recovered. Approximately 67% of the returns have been found along a 200-mile section of coastline extending from Cape St. George west to the Florida-Alabama line; 20% of the returns were from the Florida east coast and Keys; and 12% of the returns were found along the coasts of Alabama, Mississippi, Louisiana, and Texas. Comparison of the drift bottle data with local wind information indicates that the primary mechanism of surface water transport in the vicinity of the release point is wind-in duced currents, which either transport the bot tles to local s or to regions where perma nent or semi-permanent currents can displace them to western or southern shores. The results of this study are also compared with other drift bottle studies conducted in the Gulf of Mexico. (Author).

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).

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.

This atlas, and the series of which it is a part, is computer generated and automatically plotted. It makes available to the user the most recent surface current data collected and will be updated whenever sufficient amounts of data are added to the data file. This and the other atlases are based on a vast quantity of data as compared to the previous manually-compiled editions printed in the mid-thirties. The surface current information is based mainly on ship drift, which is the difference between the dead reckoning position and the position determined by any type of navigational fix. This difference describes the direction and speed of the current. (Author).
