Ballast water- Intro Problem Activities Analyses Database/Vessel Tracking

Database Developments and Vessel Tracking

We are developing a comprehensive relational database that is designed to incorporate the extensive chemical and biological data from this project, as well as the relevant vessel and ballast management data being generated. This application is a powerful tool, facilitating rapid assessment of potential risk factors for species introductions. The design process is complete and the system is currently under construction using Microsoft Access as a front-end (Figure 7). Another useful feature will be the automated linkage we are creating between the database application and ARCVIEW 8.0, a GIS mapping program. This will take the information entered into the ballast management data module of the database, such as ballasting activity and the associated coordinates, and will enable automated mapping of specific voyages. Users will be able to rapidly map a biological variable (e.g. a species) of interest, following its voyage-specific ballasting history. This functionality, coupled with the query functions of the database for the biological and chemical data, will allow for any number of mapping scenarios and on multiple scales designed to help characterize risk of species introductions. In addition, we plan to incorporate web linkages from various remote-sensing resources, to allow consideration of other factors that may be relevant to organism occurrence and density in risk assessment. For example, voyage mapping coupled with the chemical and biological observations from this study, taken with NOAA sea surface temperature animations, may demonstrate that a given locale, at a given time of year represents a high risk for uptake of water that may be diverse and/or abundant (Figure 8).
