The next challenge for those interpreting the LOICZ information lies in extrapolating baseline data for specific sites into more detailed environmental information.
The LOICZ webpage also summarizes and updates the budgeting procedure, provides tools for carrying out the process, offers teaching materials, and posts existing budgets as they become available.
The LOICZ database of detailed information about coastal ecosystems is maintained at Stockholm University in Sweden.
Members of the LOICZ project have conducted 15 workshops around the world to teach local experts how to develop nutrient budgets for their regions.
To obtain baseline information about the status of estuaries worldwide, the LOICZ model uses secondary data obtained locally, gathered, for example, by health officials, environmental biologists, or even a school laboratory activity.
In these cases, the LOICZ model uses the "Redfield ratio" to estimate carbon from known changes in nitrogen and phosphorus.
Gordon first conceived the idea of modeling estuaries for LOICZ and developed the methodology with Fredrik Wulff, a professor of marine systems ecology at Stockholm University.
The LOICZ budget model considers the flow of water, and that of the dissolved nutrients carbon, nitrogen, and phosphorus, to produce a so-called nutrient budget.
