Coccolithophores in the Gulf of Mexico (M67/2)

在拟议的研究中，我们将调查的生活颗石藻在墨西哥湾东南部的空间分布，以澄清在该地区的环境和nannoflora之间的关系。我们将检查和相关的物种出现至少磷酸盐和硝酸盐含量以及温度和盐度的手段，以缩小“传统”物种以及可用的形态型的首选生活条件。此外，它的目的是检查是否coccolithophore社区的沃茨以上冷水渗漏不同，那些没有直接受到影响。在一般情况下，我们怀疑这项研究将有助于更好地确定生态位的单一物种和颗石藻作为一个群体。

In the proposed study we will investigate the spatial distribution of the living coccolithophores in the southeastern Gulf of Mexico in order to clarify the relationships between the environment and the nannoflora in this region. We will examine and correlate the species occurrences at least to the means of phosphate and nitrate content as well as temperatures and salinities, in order to narrow down the preferred living conditions of “traditional” species as well as of the available morphotypes. In addition, it is intended to check whether the coccolithophore communities prospering in the waters above cool-water seeps differ from those not directly influenced by them. In general we suspect that this study will help to better determine the ecological niche of single species and coccolithophores as a group.
