Nannochloropsis sp., an unicellular marine microalgae, has potential function as a food source for fish larvae and in chemical industry. Microenvironmental conditions, especially nitrogen and salinity stress in marine ecosystems, became major factor affecting the growth of Nannochloropsis sp.The aim of the experiment was to study effect of different salinities and nitrogen dosages to the growth and lipid contents of Nannochloropsis sp. cells.The experiment was arranged in factorial with three replicates. The first factor was salinity (28 ppt and 38 ppt), and the second factor was nitrogen dosage (100% and 50%). Results of the experiments indicated that nitrogen starvation and high saline concentration affected cell density of Nannochloropsis sp. in different level. The results showed that combination treatments of nitrogen starvation and salinity reduced cell density (treatmant A, B, and D), except in treatment C. Combination of high salinity and high N dosages resulted ini steady growth of Nannochloropsis sp. These results suggest that Nannochloropsis sp. are able to overcome salinity stress (38 ppt) in the presence of optimum concentration of nitrogen in the growth cultures.The results also shows that there were no significant differences of crude lipid content between treatments and no correlation between population density and crude lipid content. These results suggest that no simple correlation between population density and crude lipid concentration. On the other hand, population density was not the only factor affected crude lipid concentration in the microalgae cell.Keyword: Nannochloropsis, population, crude lipid

The northeast Indian Ocean is a region crossed by the monsoon winds and bordered by mainland on northern and eastern side that allegedly the water mass is influenced by these two factors. This research aims to study the vertical dan cross section distribution of physical parameters such as temperature, salinity, and density and also to identify the types of water masses in the region. The data used are the data of temperature, salinity, and density during 2007-2010 is obtained from sensors located on spacecraft of ATLAS Mooring. There are six stations located on the 90oE and from 0-15 oN, with 4 year observation and there are 4 periods each year.Â The results of observations of temperature on the surface indicates the period from December to February and March to May have a similar pattern. While the pattern in the period from June to August is similar to September-November. In other hand, the temperatures around depth of 140 m to the bottom shows the same pattern throughout the year. Value of the sea surface temperature of the period from March to May is generally the highest. Observations of sea surface salinity and water column generally are the same in each period, the salinity values decreased from a low-latitude station towards the high-latitude stations. The differences found are the highest surface salinity values are more common in the period from December to February, which is found on the station I and III. The result of value sea surface density observations show a decline pattern of low-latitudes stations in to higher latitudes stations throughout the year, or a pattern that tends to the same of salinity pattern.Â Analysis of the TS diagram refer to Wyrtki (1961) and Emery (2003) indicates there are some type of water masses, ther are namely the Bengal Bay Water (BBW), South Indian Central Water (SICW), Indian Equatorial Water (IEW), Subtropical Lower Water (SLW), and Northern Salinity Minimum (NSM). Those water masses is found in every period, only period from December to February have differrent type of water masses, that is the Arabian Sea Water (ASW).Keywords: ATLAS Mooring, Diagram TS, Indian Ocean, Water Mass

The aim of this research is to describe the spread salinity with two dimensions numerical model at the Musi Riverâ€™s estuary, and also to determined relationship of spread salinity with hydrodynamic unsure in water. The research has been done at Juli â€“ Agustus 2011 at Musi Riverâ€™s estuary, South Sumatra. Determination of sampling points is done by using purposive sampling method. The sample is measured by in-situ method and the data is proceed using Surface Water Modelling System (SMS 8.1) software, then verified with field measurement. The result of this research indicated that when the condition of sea-water tidal waters not too far into the river, the concentration of salinity in the surface layer (0.2 D) ranged between 6 - 28o/oo, in the water column (0.5 D) between 6 - 27o/oo, and in the deep waters (0.8 D) between 5 - 27o/oo. In other hand, at low tide condition, the influence of river moved farther out to the sea, with the concentration of salinity in the surface layer (0.2 D) ranged between 5 - 26o/oo, the salinity in the water column (0.5 D) and in the deep waters (0.8 D) between 4 - 27 o/oo. The result of spread salinity of the model simulation shows that the salinity distribution patterns follow the formed of the flow so that it can be said that the flow will affect the distribution of salinity in the waters. Based on the results of the flow simulation and salinity with or without the effects of windâ€™s flow and salinity patterns are the same, in the range 0.9 to 23.9o/oo. The verified average error result of measurement and simulation the model (MRE) with or without wind is 3,163 E-11%. So, factor of the wind did not significantly affect the movement of flow on the research.Keywords: Salinity distribution, Numerical models, SMS, Estuary
