Abstract

A study of the plankton variability and their community structure in the Southern Coastal Area of East Java-Bali-Lombok was conducted to obtain the information of their characteristics and the status of microscopic marine organism in relation to the marine environment on the based of the biological observation. The results show that the marine environment ecologically was stable and productive due to the upwelling occurrencein the South East Monsoon. The plankton communities generally can be found consist of three classes of the phytoplankton (Cyanophyceae, Dinophyceae and Bacillariophyceaea) and two classes of zooplankton (Ciliata and Crustacea). There is no dominance of certain plankton in the observation area and the distribution among the species are relatively proportional.

Abstract

We developed a conceptual coupled atmosphere-ocean-ecosystem model for the South Java seas to investigate interaction between marine biota and SST variability due to monsoon-forced. Ocean and atmosphere are represented by a box model for one dimensional water column. The equation of motions of the zonal wind stress and SST are represented in term of nonlinear oscillator model. Marine biota are represented by three components (nutrient, phytoplankton and zooplankton) of NPZ Edward-Brindley model. The marine ocean-atmosphere coupling mechanism is done through the absorption of blue light by phytoplankton. The system of nonlinear dynamical equation is solved by using Matlab ODE solvers. Monthly SST data is used to compare the model. Result showed that the period and amplitude of oscillation of SST and ecosystem component strongly depend on the parameter choice which describes the dynamical characteristic of the system. The SST and ecosystem variability will strongly correlate with monsoonal wind if we choose the parameter of light attenuation by water 0.2 m-1. Strong seasonal variations associated with monsoonal winds were observed for SST, phytoplankton and zooplankton concentration. On the other hand, the nutrient concentration shows a weak seasonal variationKeywords: SST, NPZ, monsoon, delayed oscillator
