Ocean science has long been interdisciplinary. Each great ocean feature has a physical, chemical, biological, and geological signature. Phenomena associated with these features have led curious scientists to collaborate on important questions. One example is the investigation by physical and biological oceanographers of warm- and cold-core eddies (rings) spun off the Gulf Stream in a well-known sequence of productive, coupled projects in the 1980s (Ring Group, 1981). The interactions among investigators from different disciplines were crucial to developing the inherent understanding of the ring phenomena as well as their biological and physical ramifications.
