Abstract

The ocean dynamics of the marginal seas in the Java-Makassar-Flores (JMF) Triangle seas facilitates the seasonal exchange of water masses between Java, Makassar, and Flores, which influences the occurrence of small pelagic fish. This research investigates seasonal fluctuations in sea currents, seawater temperature, salinity, and phytoplankton primary production (PPN and PPD) based on validated model output datasets from NEMO and PISCES from the INDESO simulation (2008–2015). The model demonstrated seasonal exchanges of the top 50 m of water masses in the area, where the eastward monsoon current transported freshwater (salinity<31 psμ) from the Java Sea to southern Makassar and Flores. This northwest monsoon produced a much fresher water in the southern region of Makassar and western region of Flores. During the southeast monsoon, the surface component of the Makassar throughflow, which transports saline water (salinity >34 PSU) into the Java Sea, pushes fresh Java waters westward. Seasonal salinity changes and PPN/PPD in the shelf region of southern Kalimantan correlated with substantial small pelagic fishing.

爪哇-望加锡-弗洛雷斯（JMF）三角海域的水质交换：模型研究

爪哇-望加锡-弗洛勒斯（JMF）三角海域边缘海的海洋动力学促进了爪哇、望加锡和弗洛勒斯之间的水团季节性交换，从而影响了小型中上层鱼类的出现。本研究根据 INDESO 模拟（2008-2015 年）中 NEMO 和 PISCES 的有效模型输出数据集，研究了海流、海水温度、盐度和浮游植物初级生产力（PPN 和 PPD）的季节性波动。该模型显示了该地区顶部 50 米水团的季节性交换，东向季风流将淡水（盐度为 31 psμ）从爪哇海输送到望加锡南部和弗洛勒斯岛。西北季风为望加锡南部地区和弗洛勒斯岛西部地区带来了更为清新的海水。在东南季风期间，马卡萨贯穿流的地表部分将盐水（盐度为 34 PSU）输送到爪哇海，并将爪哇淡水向西推送。加里曼丹南部陆架地区的季节性盐度变化和 PPN/PPD 与大量小型中上层捕捞活动有关。

期刊介绍： Continental Shelf Research publishes articles dealing with the biological, chemical, geological and physical oceanography of the shallow marine environment, from coastal and estuarine waters out to the shelf break. The continental shelf is a critical environment within the land-ocean continuum, and many processes, functions and problems in the continental shelf are driven by terrestrial inputs transported through the rivers and estuaries to the coastal and continental shelf areas. Manuscripts that deal with these topics must make a clear link to the continental shelf. Examples of research areas include: Physical sedimentology and geomorphology Geochemistry of the coastal ocean (inorganic and organic) Marine environment and anthropogenic effects Interaction of physical dynamics with natural and manmade shoreline features Benthic, phytoplankton and zooplankton ecology Coastal water and sediment quality, and ecosystem health Benthic-pelagic coupling (physical and biogeochemical) Interactions between physical dynamics (waves, currents, mixing, etc.) and biogeochemical cycles Estuarine, coastal and shelf sea modelling and process studies.
