"大氣中越來越多人為產生的營養鹽物質物種(reactive nitrogen species)透過沉降進入海洋，能提高每年海洋生產量約3%。自然界中，主要的磷來自於風化作用與河川輸入，分別為15-20 和 22 Tg-P yr-1。若是根據目前的人口增加速率，到了2050 年人口數將比2000 年增加50%來到90 億人口數；因此，對於食物的需求也會跟著增加。在本計畫中，我們將以離島測站(馬祖與彭佳嶼)平行採樣資料，探討藉由大氣輸送的水溶性磷物種進入東海和西北太平洋的量。從我們過去發表的相關論文(Chen and Chen, 2008; Chen et al., 2010, 2011, 2015)，我們將這些資料統整，以估算大氣中水溶性磷物種進入西北太平洋表層的通量。我們過去的研究發現，這些通量明顯受到氣團來源區域的影響。因此，本計畫的目標有： (1) 藉由氣膠採樣器採集大氣懸浮微粒，瞭解活性水溶性磷物種濃度隨時間分佈的情形，藉以探討有機磷物種之傳輸機制。 (2) 利用主要陰、陽離子鑑識技術及統計分析，針對大氣懸浮微粒中水溶性磷物種成份含量特徵追蹤來源。 (3) 藉由各樣品間的相關性，判別大氣懸浮微粒中水溶性磷物種之來源。 (4) 計算水溶性磷物種之通量值，瞭解區域相對貢獻程度；並提供其他子計畫大氣水溶性磷物種輸入資訊，以探討其對海洋環境生態之影響。" "Increasing amounts of atmospheric anthropogenic nutrient species are being deposited into oceans, thereby increasing the annual marine biological production by approximately 3%. So far, the major inputs of phosphorus are from the weathering process and riverine input which are 15-20 and 22 Tg-P yr-1. According to the current population growth rate, the global population in 2050 will be 9 billion, which is a 50% increase from the population in 2000, indicating that the demands for food will grow. In this work we attempt to derive atmospheric soluble phosphorus inputs to the East China Sea and Northwest Pacific Ocean using parallel sampling between two remote island (Matus and Pengjia). While the results of these data have been published (Chen and Chen, 2008; Chen et al., 2010, 2011, 2015), the goal of this research is to draw all our data together and estimate soluble phosphorus inputs to surface Northwest Pacific waters. We have previously observed that soluble phosphorus concentrations in aerosol samples collected over the Northwest Pacific are heavily influenced by the air-mass derived source regions. The objective of this research include characterization of (1) transportation mechanisms of soluble phosphorus in different season of the study area, (2) derived sources of air mass by using sodium ion (sea-salt ion) and non-sea-salt ions, (3) sources of atmospheric soluble phosphorus by using correlation analysis, and (4) impact of atmospheric soluble phsophorus inputs on marine environment in this region."
