The Ocean View Data Visualization Tool website provides data for 13 ocean locations (including north and mid Altantic, north and south Pacific). This data includes temperature, salinity, oxygen saturation and dissolved oxygen. The user can select two locations to compare side by side. By mousing over the bouys, the user is given the exact location of the collection site. Once two sites are chosen the user can then compare an entire years (January 1998 - December 1998) worth of data, month by month. The graphing tool allows the user to select only one set of data, such as temperature or any combination of the four (temp., salinity, dO2, oxy. sat.)from surface to a maximum depth of 1000 meters . The interactive map also shows surface and deep ocean currents. The site also contains sample lessons to illustrate how the data may be used by students to answer questions about the ocean parameters.
