在麦哲伦海峡及其邻近的Bell Bay、Oracion Bay和Brinkley Island三个海域的采样站，测量了春季和夏季浮游生物的叶绿素a （25 μm）。研究结果表明，在春末（11月、12月、1月）四区浮游植物群落中，网络浮游植物组分的生物量占重要组成部分（68%）。在这些沿海站登记的大型链状硅藻物种的优势支持了这一点。而在麦哲伦海峡的早春（9、10月）和贝尔湾、奥拉贡湾和布林克利岛的夏季（2、3月），浮游生物和n-浮游生物组分的贡献更大（约67%）
Picoplankton ( 25 μm) chlorophyll a were measured during the spring and summer months at sampling stations in the Strait of Magellan and three adjacent areas: Bell Bay, Oracion Bay and Brinkley Island. The results obtained in the present study indicated that the biomass of the netphytoplankton fraction became an important component (68%) of the phytoplankton community during late spring (November, December, January) in all four areas. This is supported by the dominance of large chain-forming diatom species registered in these coastal stations. In contrast, the contribution of pico- and n-anoplankton fractions became important (> 67%) during early spring (September, October) at the Strait of Magellan and during summer (February, March) at Bell Bay, Oracion Bay and Brinkley Island
