  2. The Computer Assisted Budget Analysis for Research, Education, and Training or LOICZ-CABARET was designed to simplify the process of calculations in applying the LOICZ approach to biogeochemical budget calculations. This current version can assist in the calculation of the water, salt, and nutrient budget of any single-box or multi-box single-layer or multi-layer system by seasons or monthly. It can also assist in the calculation of the area and volume of a system in its entirely or treated as sub-systems through its on-screen digitization. Finally, to circumvent observed complications of previous users in unit conversions, the LOICZ-CABARET automatically transforms units into m3/yr for easier comparison between systems. Results are displayed in the familiar LOICZ box-diagram format. • Statement of Purpose Additional improvements are periodically posted at the LOICZ webpage www.nioz.nl/loicz For questions and suggestion, contact LOICZ@usa.net

  3. The program can be downloaded from the LOICZ webpage as an executable ZIP file. It is best if the downloaded file is placed and unzipped inside a blank folder. All future working files must reside in this folder for the program to work. To unzip, just double click the executable zip. Run program by double-clicking on cabaret.exe The program should work in windows 95/97/2000 and NT.

  4. Sequentially fill in the necessary data. To help guide users through the program, a flow chart can be accessed at any time by clicking on the menu choice named FLOWCHART. Close the flowchart window by clicking DONE. • FLOW CHART

  5. In order to be duly recognized as a contributor, make sure to fill in the Contact Person Information Window. Note that the two buttons at the bottom allows the user to go back to the previous window (B) or forward to the next sequential window (N) • ALPHA/PERSONAL

  6. Site description goes inside this window. It is necessary to enter the following fields: • ESTUARY NAME • COUNTRY • THE NORTH, SOUTH, EAST, WEST BORDERS OF THE SYSTEM • NO. OF SEASONS & THE START AND END MONTHS OF EACH SEASON • ALPHA/DESCRIPTION

  7. Choose the type of system The No. of boxes The No. of layers The area per box If the area is unknown, LOICZ-CABARET also allows for the estimation of the area using the on-screen digitization. To use this feature you must have a bmp image of your system. Type in the length of your calibration bar found in most maps or use the latitude lines and then click on the MAP button. • CALIBRATE

  8. A small window asking for the bmp file name opens when you click on MAP. The map image then opens. Click the ends of the calibration bar then click DONE. • BMP OF MAP

  9. To estimate the area per box, double-click on the corresponding box area. This will once again open the bmp image of your system. • ESTIMATING BOX AREA Digitize the box area on-screen. The box area polygon is designed to automatically close upon clicking of DONE.

  10. The water, salt and nutrient data are typed in this window. • The minimum fields to be filled are the following: • Layer depth • At least one freshwater flow • At least the salt and nutrient concentration of the outer box and the system box • This should be done per box and per layer. • Afterwards, click BUILDHTML • ALPHA/MATERIALS

  11. RESULT - WATER AND SALT BALANCE Results can be viewed using any web-browser. Make sure to re-load the page after every edit.

  12. RESULT - PHOSPHATE & NITRATE BALANCE

  13. It is hoped that LOICZ-CABARET will not only encourage the users to contribute to the LOICZ endeavor but also experiment with the forcing functions and response sensitivity of their systems. Finally, LOICZ-CABARET is also envisioned to be used as a teaching tool in estuaries and coastal lagoon studies. • VISION
