Statement of Purpose
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.
Additional improvements are periodically posted at the LOICZ webpage

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.

FLOW CHART
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.

ALPHA/PERSONAL
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/DESCRIPTION
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

CALIBRATE
Choose the type of
system
The No. of boxes
The No. of layers
The area per box
If the area is
unknown, LOICZCABARET also allows
for the estimation of
the area using the onscreen 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.

BMP OF MAP
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.

ESTIMATING
BOX AREA
To estimate the area
per box, double-click
on the corresponding
box area.
This will once again
open the bmp image
of your system.
Digitize the box area
on-screen. The box
area polygon is
designed to
automatically close
upon clicking of
DONE.

ALPHA/MATERIALS
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

RESULT - WATER AND
SALT BALANCE
Results can be viewed
using any webbrowser.
Make sure to re-load
the page after every
edit.

RESULT - PHOSPHATE & NITRATE BALANCE

VISION
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.
