One of the duties of an oceanographer besides field surveys is also the role of the “master mind” as a modeler. Working as a modeler
is not like designing clothes then walking in style on the cat walk. However, oceanographers as modelers are tasked with transferring
oceanographic phenomena into discrete or numerical equations, then numerical models in the field of oceanography are known as oceanographic
modeling. Many things can be modeled, from the simplest to the most complex though.
The use of oceanographic modeling is to study ocean behavior more easily and inexpensively but in detail. The convenience offered is
because a modeler does not need to go directly to the field, as it is known that oceanographic surveys are expensive and difficult.
Modeling is very detailed because as a modeler the study location can be used as cells to a fairly tight scale. In the development of
oceanography, this numerical model helps oceanographers in explaining the phenomena observed in nature in greater depth. Some that are
quite popular are the Stommel model which successfully explains the phenomenon of intensification of western boundary currents and the
Sverdrup model regarding ocean circulation. At present, it seems that almost all oceanographers' work is greatly assisted by numerical
models, especially with the rapid development of computing technology. Many tools for oceanographic numerical models have been
developed and can be easily accessed, ranging from only 1D, 2D, to 3D with a variety of different methods and their respective advantages.
Oceanographic modeling and forcesting that can be done by us are as follows:
• hydrodynamic models such as ocean wave currents, tides, and sediment transport.
• Marine environment models such as particle tracking of pollutants or debris
• Coastal models such as shoreline change and coastal vulnerability
We are supported by a workforce of experienced and experts in their fields. In building a model, we pay close attention to every detail so that errors do not occur and the output produced is as expected. Therefore, caution is required in building a model, and of course a good understanding of numerical models and matters related to oceanography is required.
