Prepared in cooperation with the Global Temperature-Salinity Profile Program (GTSPP)

This summary represents real-time open ocean data and data from three shelf regions, specifically the Gulf of Maine, North and Baltic Seasand off-shore of the United States. The intent is to demonstrate the growth in ocean observations as new observing systems become operational (ARGO for example) and more Nations participate in Global programs (GOOS for Example).  The graph should not be interpreted as full representation of ocean observations, open ocean nor, particularly, shelf.
