Phytoplankton North Adriatic-Gulf of Trieste C1 – LTER time-series 2006-2009

Time series of phytoplankton abundance collected with a monthly frequency at 0.5, 5, 10 and 15 meters in the Gulf of Trieste. The time series station C1, located in the Gulf of Trieste in the northernmost part of the Adriatic Sea, is part of the Adriatic Long Term Ecological Research (LTER) site. It is a shallow coastal station (17 m depth) located at 0.2 Km from the coast, at the outer border of the Natural Marine Reserve of Miramare, Trieste. More information about activities carried out and about datasets from other periods can be found at: http://nettuno.ogs.trieste.it/ilter/GoTTs/en_index.html. Samples were fixed with Ca(HCO3)2-buffered formaldehyde (0.8% final concentration) and cell abundance was estimated according to Utermöhl’s method (1958), using an inverted microscope equipped with phase contrast, at 200-320-400x final magnifications. Abundant cells were counted in defined random fields, rarer species were counted on the whole chamber (Fonda Umani et al., 2007).

本数据集为在的里雅斯特湾（Gulf of Trieste）海域，以月度频次于0.5米、5米、10米及15米水深采集的浮游植物丰度时间序列。
站位C1坐落于亚得里亚海（Adriatic Sea）最北端的的里雅斯特湾内，隶属于亚得里亚海长期生态研究（Long Term Ecological Research, LTER）站点。该站位为近岸浅海站位，水深17米，距海岸0.2公里，位于的里雅斯特米拉马雷自然海洋保护区的外围边界处。

样品采用终浓度为0.8%的碳酸氢钙（Ca(HCO3)2）缓冲甲醛溶液固定，细胞丰度依据1958年提出的乌特莫尔（Utermöhl）法进行估算：使用配备相差物镜的倒置显微镜，以200倍、320倍、400倍的最终放大倍率进行观测。丰度较高的细胞在指定随机视野中计数，稀有物种则对整个计数室进行全片计数（Fonda Umani等，2007）。
