项目标书摘要：海龟为一大洋洄游的物种，终其一生95%以上的时间都在海上渡过，因此海洋环境的特性会影响海龟在海上的行为，由近几年的研究显示，大洋中的物理现象如洋流、锋面、风、地磁、bathymetric features、海水表面温度分布、path integration 等均是影响或是决定海龟洄游行为的重要环境因子。从许多质化及量化的研究中显示在各种因子中，洋流对海龟的影响最大。因此了解动物如何利用洋流以顺利地到达目的地，对其族群的存续，有着非常重要的意义。而海龟的洄游路径配合其潜水行为，能使我们以3-D 而非平面2-D 的概念，深入且正确的了解海龟在海上的行为。这对於进行海洋动物的行为研究及保育策略的制定，都有着不可磨灭的贡献。虽然本研究已找到洋流影响海龟洄游的部份证据，也解答出海龟在大洋中如何利用洋流洄游到其觅食地及部分的潜水行为，但仍不完全了解在不同海域中，其洄游行为与海流间的关系。对於母龟在产卵期结束，及其他海龟在遭到混获和救伤痊癒後，进行野放之洄游及潜水行为的所知也十分有限。因此本研究的目的是利用人造卫星追踪的资料，配合物理海洋的洋流模式加以分析，以量化的方式来了解，海龟在不同的活动阶段，如从产卵季进入产後洄游期及到达觅食海域後，或是进入不同海域後，其洄游行为，有多少是受到洋流的影响。这对了解海龟的生理能量上之开销及适应环境变化之行为表现，有着很重要的意义。由於海龟一生中超过95%的时间是在海上渡过的，本研究将使我们更了解牠的生存策略，及采取有效的保育措施。

Application Abstract: Sea turtle is a oceanic migratory species,spends more than 95%time at sea.Therefore,the hydrodynamic environmental characters can influence the behavior of sea turtle at sea.Recent studies showed that,the physical characters in the ocean,such as current,front,wind,geomagnetic field,bathymetric features,distribution of sea surface temperature,path integration,are the important environmental factors that influence or determine the migration behavior of sea turtles.Many qualitative and quantitative studies suggested that among various factors current is the most influential factor.Thus,to understand how animal use current to reach its final destination is crucial to the survivorship of the population.The combine of migration track with diving behavior enable us to understand the sea turtle behavior in the open ocean in detail with 3-D instead of 2-D concept.This will provide indelible contribution to the studies of the behavior of marine animals and development of conservation strategies.Although our studies have found part of the evidences and found some evidences how animal utilize the current to reach its foraging site and diving behavior.However,we still not fully understand the relationship between migratory behavior of sea turtles and the ocean current in different hydrodynamic regimes.The knowledge on the migration and diving behavior of the post-nesting green turtles and rehabilitated as well as by-catch release sea turtles are also limited.Thus,the purpose of this study is to analyze the data obtained from the satellite telemetries along with the hydrodynamic models obtained from the physical oceanography to determine quantitatively to what extent the migration does influenced by the currents as well as their own will when migrate through different stage of activities,such as change from inter-nesting to post-nesting to residential stages,or migrate from one hydrodynamic regime to the other.This is very important to the physiological energy expenditure of sea turtles and the change of behavior in response to the change of marine environment.Because sea turtle spends more than 95%of their life on the sea,this research will enable us to understand their survival strategies and conduct effective conservative measures.
