21 July 2016

This newsletter details the use of symbols as a visual language. Symbols are useful for depicting unequivocal messages that transcend cultures, languages and times. The use of symbols to construct conceptual diagrams ('thought drawings') can be an effective tool for science communication and problem solving. Conceptual diagrams help to clarify thinking and provide a communication interface between scientists and non-scientists.

New York Harbor is a large, iconic and complex body of water that has been extensively modified to support the development of a megacity. These modifications have affected the shorelines, water flow, water quality, habitats and living resources of the harbor. Changes in topography and bathymetry have altered the landscapes and seascapes of the region, largely to support an active shipping port and intense human settlement.
