“…These results corresponded with the previous results of studies that used chlorophyll-a concentration data from both SeaWiFS and Aqua-MODIS sensor (Susan et al, 2001, Lumban-Gaol et al, 2002, Hendiarti et al, 2004, Kunarso et al 2011) that stated that the chlorophyll-a concentration would be maximum during the peak of upwelling process was in August or September. In east monsoon wind blew from the southeast and fully pushedthe sea water masses along the south coast of Java, due to the coriolis forced the sea water masses would be diverted away from the south coast of Java, causing sea water masses emptiness (Figure 3-5).…”

Estimating specific inherent optical properties of tropical coastal waters using bio-optical model inversion and in situ measurements: case of the Berau estuary, East Kalimantan, Indonesia

et al. 2010

Specific inherent optical properties (SIOP) of the Berau coastal waters were derived from in situ measurements and inversion of an ocean color model. Field measurements of water-leaving reflectance, total suspended matter (TSM), and chlorophyll a (Chl a) concentrations were carried out during the 2007 dry season. The highest values for SIOP were found in the turbid waters, decreasing in value when moving toward offshore waters. The specific backscattering coefficient of TSM varied by an order of magnitude and ranged from 0.003 m 2 g -1 , for clear open ocean waters, to 0.020 m 2 g -1 , for turbid waters. On the other hand, the specific absorption coefficient of Chl a was relatively constant over the whole study area and ranged from 0.022 m 2 mg -1 , for the turbid shallow estuary waters, to 0.027 m 2 mg -1 , for deeper shelf edge ocean waters. The spectral slope of colored dissolved organic matter light absorption was also derived with values ranging from 0.015 to 0.011 nm -1 . These original derived values of SIOP in the Berau estuary form a corner stone for future estimation of TSM and Chl a concentration from remote sensing data in tropical equatorial waters.

“…8, 9). A dense cloud cover shading the surface ocean from space observations could have caused this decoupling during the rainy season (Hendiarti et al, 2004). Although the same problem occurs in summer during the upwelling season in the Arabian Sea (Banse andEnglish, 2000, 1994) the long-term mean organic carbon flux and primary production rates reveal 30 the same seasonality (Fig.…”

Abstract. In this study, data obtained from a sediment trap experiments off South Java are analyzed and compared to satellite-derived information on primary production and data collected by deep-moored sediment traps in the Arabian Sea 10 and the Bay of Bengal. The aim was to study the relative importance of primary production and the ballast effect on the organic carbon export and the CO 2 uptake of the biological carbon pumps. Therefore, data obtained from sediment trap experiments carried out in other ocean basins were also integrated into the data analysis and a four-box model was developed. Our data showed that the organic carbon flux in the highly-productive upwelling system in the Arabian Sea was similar to those in the low productive system off South Java. Off South Java as in other river-influenced regions, lithogenic 15 matter supplied from land mainly controls the organic carbon flux via its ballast effect in sinking particles, whereas carbonate produced by marine organisms appears to be the main ballast material in the high productive regions. Since the carbonate flux tends to increase with an increasing export production, it is difficult to quantify the relative importance of productivity and the ballast effect on the organic carbon flux into the deep sea. However, the export of organic matter into the deep sea represents a loss of nutrients for the pelagic ecosystems, which needs to be balanced by mode water nutrient 20 supply into the seasonal thermocline to sustain the productivity of the pelagic system. The amount of preformed nutrients utilized during the formation of the exported organic matter strongly influences the impact of the ballast effect on the CO 2 uptake of the organic carbon pump. Accordingly, this is stronger at higher latitudes where preformed nutrients are formed than at lower latitudes where the euphotic zone is nutrient depleted. Nevertheless, the ballast effect enhances the export of organic matter into the deep sea and favors the sedimentation of organic matter in river-influenced regions. Since globally > 25 80% of organic carbon burial occurs in river-dominated systems, the lithogenic ballast is assumed to play an important role in the Earth's climate system on geological time scales.
