A Survey of Chrysophyte Ultraplankton from the Open Oceans

超级浮游生物提供了公海70%-80%的初级生产力。超级浮游生物主要有三类：(1)原核生物；(2)绿藻；(3)金藻。国际海洋研究所建议在北大西洋和北太平洋调查两大类金藻-金藻和金藻--的超浮游植物，制作完整的标本和切片材料，培养收集的标本，研究这些标本和培养物-以及已经在手的培养物-使用电子显微镜。这些分类群很少被收集，更少的是在培养中。因此，尽管它们在世界初级生产中具有重要意义，但人们对它们的生物学知之甚少。这项研究应该开始通过将物种编目并提供给深入研究来纠正这种缺乏知识的情况。

Ultraplankton provide 70-80% of the primary productivity of the open oceans. There are three major groups of ultraplankton (1) prokaryotic organisms; (2) green algae; and (3) golden algae. The PI proposes to survey the North Atlantic and North Pacific oceans for ultraplankton members of the two protistan classes of golden algae---Chrysophyta and Prymnesiophyta, to produce whole mounts and sectioned materials, to culture the collected specimens, to study these specimens and cultures---and cultures already in-hand --- using electron microscopy. These taxa are seldom collected and even fewer are in culture. Consequently, little is known about their biology, in spite of their significance in world primary production. This study should begin to rectify that lack of knowledge by cataloging the species and making them available for in-depth studies.
