North Atlantic Ocean Gulf Stream


Probably the most dominant oceanographic feature of the western North Atlantic Ocean is the Gulf Stream. The northern edge of that current is clearly visible in the chlorophyll field measured by SeaWiFS. As the Gulf Stream flows eastward it forms meanders that occasionally pinch off to form clockwise-rotating warm-core rings to the north and counterclockwise- rotating cold-core rings to the south. Cold-core rings generally have higher chlorophyll concentrations (and lower surface temperatures) than the surrounding water. Image Credit: NASA SeaWiFS
