本研究探討台灣東北海域龜山島海底熱泉湧出及擴散對此海域浮游動物與熱泉生物生態及補添量之機制，本研究擬結合海洋生物學與生物海洋學之知識來分析龜山島日以繼夜終年的熱泉湧出對浮游動物（包括holoplankton 和meroplankton）與熱泉生物之存活率、生活史、歧異度、污染物累積量、生物含量和分佈之影響。本研究主要著重在龜山島淺海熱泉噴口之海洋物理傳輸過程對浮游動物所形成的影響以及浮游動物之生態毒理學的耐受性研究。尤其探討垂直剖面離熱泉1，5，10 米距離之活體熱泉浮游動物及幼體以瞭解浮游動物之垂直剖面的時空變化及生態毒理學的耐受性研究。同時我們也將研究水平直線距離熱泉數十至數百公尺遠的浮游動物與熱泉生物之活體分佈以及行為模式作為研究之基礎。採樣時間擬從2011 年8 月到2014 年7 月。我們擬探討熱泉浮游動物與熱泉生物幼體靠近海底熱泉區的豐度與遠離熱泉區的比較。由於熱泉生物生殖期之不同可能會產生時空上之明顯的變化，因為熱泉生物之繁衍可能與其浮游幼期之輸送機制有關，本研究將增加我們對熱泉生物相之生殖及輸送形式有更進一步的瞭解，本研究亦將涵蓋野外採樣分析與研究室實驗同時並行。研究結果將使我們對海底熱泉湧出及擴散對此海域浮游動物與熱泉生物存活率、污染物累積、生態及補添量之機制有更進一步的瞭解。Zooplankton and vent animals’ diversity, abundance and distribution patterns – comprising holoplankton and meroplankton - will be studied near shallow water hydrothermal vents at Turtle Island, off the northeast coast of Taiwan (west Pacific), in order to investigate how physical transport processes and the ecotoxicological tolerance and particularly behavior of plankton may interact. We will characterize vertical and lateral distributions and temporal variation of plankton and larvae of vent species. Vertical distribution patterns at heights of 1, 5, 10m above the seafloor and the surface distributions were positioned directly above and at 10s to 100s of meters away from vent communities will be studied. Sampling will be conducted at different spatial and temporal scales from August 2011 to July 2014. Larval abundances will be compared both on-vents and away from them. Lateral abundance patterns will be studied since hydrodynamic processes may have transporting impacts on the populations and assemblages of copepods. However, the species-level differences in temporal patterns indicate that there is substantial discontinuity in the abundance of individual species at vent communities, possibly due to the timing of spawning and/or behavioral interactions with flow. This analysis will provide evidence of a potential bottle-neck situation for plankton above vent sites that will also influence larval dispersal from, and supply to, vent populations. The intended study will improve our understanding of reproductive and dispersal patterns of hydrothermal vent fauna since besides facilitated field surveys the shallow vent site allows for experimental approaches.
