Extended Benefits of Collaboration

• System provides data in previously unsampled region within MARCOOS

• Data will aid in the development of improved and expanded nowcast/forecast model.

• Reporting to NWS FO to develop improved flood impact tables

Extended Benefits of Collaboration

• Research Initiatives– New Jersey Marine Science Consortium

Vulnerability Project– Collaborative Proposal to NOAA Climate

Program to develop Historic and future (sea level rise) visualizations for community planning and preparedness
