    Abstract: Zooplankton has an important role in thropic ecology at coastal area. According to their ecological function as the first consumer, zooplankton linked between producers (phytoplankton) and other marine organisms in the higher thropic level. The abundance of zooplankton in coastal area can be indicate as secondary productivity and as a food source for fisheries. This study aims to examine the biodiversity of zooplankton in coastal area of Keffing Island, Eastern Seram regency. Sampling was conducted in November 2017 during November (transitional season II) using NORPAC net (mesh size 300 micrometer) with vertical hauling from 10 meter of deep to the surface water. Samples were preserved with 4% formaldehyde and identify in the laboratory. The results showed that the biodiversity of zooplankton during transitional season II was 28 species, which copepods are the dominant taxa (13 species, 46.43% of total zooplankton). The total abundance of zooplankton is 351-1190 individu/m3, which Oncaea sp, Eucalanus sp and Corycaeus sp are abundant. Study biodiversity in coastal area of Keffing Island is important to support fisheries management programs. Avalaibility of data on the composition and abundance of zooplankton can be used as baseline data of secondary productivity and potency of natural food source in coastal area. Zooplankton mempunyai peranan penting dalam jejaring ekologi perairan pesisir. Posisinya sebagai konsumen pertama akan menghubungkan antara produsen dalam hal ini fitoplankton dengan biota pada tingkat tropik level di atasnya. Kelimpahan zooplankton di suatu perairan dapat menggambarkan produktivitas sekunder dan potensialitas pakan alami dari sumberdaya perikanan di suatu perairan. Penelitian ini bertujuan untuk mengkaji biodiversitas zooplankton di perairan pesisir Pulau Keffing, Seram Bagian Timur (SBT). Penelitian ini dilakukan pada bulan November 2017 (musim peralihan II). Pengambilan sampel dilakukan dengan menggunakan jaring NORPAC (mata jaring 300 mikrometer), ditarik secara vertikal dari kedalaman 10 meter menuju permukaan. Sampel dipreservasi menggunakan formalin 4%, dan diidentifikasi di laboratorium. Hasil penelitian menunjukkan bahwa biodiversitas zooplankton selama musim peralihan II sebanyak 28 jenis. Komposisi jenis copepoda mendominasi dengan 13 jenis (46,43% dari total komposisi zooplankton). Kelimpahan Total zooplankton berkisar antara 351-1190 ind/m3. zooplankton yang melimpah dari jenis Oncaea sp., Eucalanus sp. dan Corycaeus sp. Kajian tentang biodiversitas zooplankton di pesisir Pulau Keffing sangat penting untuk mendukung program pengelolaan sumberdaya perikanan. Ketersediaan data komposisi dan kelimpahan zooplankton dapat digunakan sebagai data dasar produktivitas sekunder dan potensi pakan alami di perairan.

    Abstract: The dynamics abundance of zooplankton in Morella coastal waters is poorly known.The purpose of this study was to detemine the abundance of zooplankton in Morella coastal waters during Southeast Monsoon. This research was conducted in August 2011. Plankton samples were collected from five stations, by NORPAC net that was vertically hauled from 10 meter depth up to the surface (except in Station 5, less than 10 m). The result showed that composition of zooplankton in Morella consisted of 43 taxa of zooplankton (33 taxa of holoplankton and 10 taxa of meroplankton). Total abundance of zooplankton was between 752 and 1050 ind/m3 (average 890±128 ind/m3), which was dominated by Copepods (53.70%). The abundace of the Copepods was between 368 and 742 ind/m3 (average 481±153 ind/m3). Copepods that typically found in coastal water may have higher tolerant on oceanographic factors than one that typically found in oceanic water. Sagitta enflata was identified as the most abundant, followed by Oncaea sp and Acrocalanus gibber. Echinoderms larvae were abundant in the pluteus stage (8 arms) indicated that spawning process occurred in August. The Bray-Curtis clustering analyses showed that in station 4 there were six different species zooplankton indentified in this location.   Keywords: structure community, copepods, meroplankton, chaetoghnata, Morella

    Hydrodynamic Conditions of the Banda and Northern Arafura Seas in the Northwest Monsoon (Februay2014)

    Abstract: The physical and hydrodynamic conditions in the Banda and Northern Arafura Seas (BAS) during northwest monsoon (February 2014) were investigated using a three-dimensional baroclinic nonlinear numerical model—the Hamburg Shelf Ocean Model (HAMSOM). This study found that northwesterly winds induced eastward surface currents that transported relatively fresh water from the Flores Sea to the Arafura Sea via the Banda Sea. It was also found that the westerly surface currents carried relatively cold water induced by upwelling along the northern coast of the Lesser Sunda Islands. Furthermore, the simulation results revealed that relatively saline surface water from the Indian Ocean intruding through the Ombai Strait and Timor Passage contributed to the surface water of the Eastern Banda Sea and Aru Basin being more saline than the surrounding water. Part of the surface water sank as a result of downwelling in the Arafura Sea. The BAS had higher salinity than the Makassar Strait at a depth of 75 –300m. The simulation results suggested that the higher salinity was due to the influence of the South Pacific Subtropical Water (SPSW) that entered the Indonesian Seas primarily through the Halmahera Sea.

    Abstract: The Cooperative Study of Kuroshio and its marginal seas (CSK) is one of the international joint research project conducted in the Western Pacific region. Many Asian countries had been involved in this project from 1965 to1979. Data and information from the CSK are enormous and cover wide-ranging aspects of marine science from the Kuroshio and adjacent regions (e.g. physical aspects, biological aspects and biogeochemical aspects). Indonesia had committed to participate actively in several marine research programs in the area linked to the CSK program by conducting marine research in its internal waters. This essay explained the CSK from biological aspects and Indonesia perspective. During the CSK, biological aspects (e.g. primary productivity, zooplankton biomass, and fisheries) were studied intensively. Indonesia conducted research in internal waters (Natuna Sea and the Java Sea) for oceanography monitoring and fish stock assessment. Participation in the CSK program allowed Indonesia to pursue the establishment of the National Center for Ocean Research (NCOR), develop human capacity building, research properties and standardized all techniques and procedures related to oceanography aspects. After the CSK, Indonesia has continued to conduct marine research linked to the previous study. We learn a lot from the past CSK that a key to succeeding in running this program depending on co-operative spirit, enthusiastic in understanding marine science from the region and enhancing human capacity for doing better marine research.

    Abstract: The aims of this research were to investigate the species richness and abundance of Copepods. Copepods were sampled using rosette sampler (surface, 25 m and 75 m) on November 21 st – 30 th , 2013, from the Banda Sea. A total of 21 taxa of Copepods belonging to three orders were identified. Calanoid was identified as the most richness order, followed by Cyclopoid and Harpacticoid. The highest value of total abundance in the surface water is 121 ind/6L, in the 25 m of depth is 221 ind/6 L, and in the 75 m of depth is 96 ind/6L. Acrocalanus longicornis is the most abundant taxa of Copepods, followed by Acartia bispinosa, and Subeucalanus mucronatus. The most predominant taxa of Acartia bispinosa, and Subeucalanus mucronatus showed a remarkable peak at 25 m layers.
