A chronology constructed from satellite-derived thermal imagery is presented to describe the formation and life history of warm-core ring 82B. This overview provides insight into a classification of features and discrete events associated with Gulf Stream warm-core rings and allows these events, as well as our limited shipboard observations, to be placed in a broader spatial and temporal context than would otherwise be possible without the satellite data. Events influencing the evolution of 82B include environmental factors, such as meteorological influences and Gulf Stream interactions, as well as those stimulated by encounters with changes in bottom topography. The interactions of the ring with surrounding waters are especially noteworthy, and the existence of vortex-vortex interactions is shown to be a significant cause of local water advection through streamer activity. Ring events are documented by following changes in ring size, shape, translation, and surface thermal structure. Our satellite observations are supported by extensive contemporaneous shipboard observations, including XBT, CTD, BOPS (biooptical profiling system) temperature profiles, and along-track sea surface temperature measurements. In addition, acoustic velocity profiling and drifter trajectories have been used to corroborate hydrographic features of the ring and environs. These ship and satellite data form a coherent space/time overview of the ring and its environment and show them to be closely related and continually interacting.
