Phytoplankton in Oneida Lake, New York, 1975 to present

This dataset contains phytoplankton data from Oneida Lake from 1975 to present and is part of the collection Cornell Oneida Lake Data. The Cornell Biological Field Station (CBFS) serves as a primary field site for aquatic research at Cornell University (more information can be found at http://cbfs.dnr.cornell.edu/index.html) and is part of the Department of Natural Resources, College of Agriculture and Life Sciences ,Cornell University. The centerpiece of the station's research program is a 60-year database on the food web of Oneida Lake, New York, that has been collected with support from the Cornell University Brown Endowment and from the New York State Department of Environmental Conservation. The data are collected by personnel from the Cornell Biological Field Station and include limnology, benthos, zooplankton, phytoplankton, and fish survey data, primarily from Oneida Lake and spanning 1957 to the present. This data package contains results of phytoplankton surveys of Oneida Lake, New York divided in two series: 1975 - 1995 and 1996 to present. The primary tables give densities of phytoplankton taxa identified in samples collected from sites in Oneida Lake. Five of these sites are standard sites and used when stations are pooled. A derived table has the densities and biovolumes of each taxa averaged over the five standard stations (1975 to 1995 data). Supplemental tables provide explanations of the taxonomic codes used in the two primary tables as well as geographic coordinates and information for the sampling sites.

本数据集收录了1975年至今纽约奥奈达湖（Oneida Lake）的浮游植物数据，隶属于康奈尔奥奈达湖数据集（Cornell Oneida Lake Data）合集。康奈尔大学生物野外站（Cornell Biological Field Station, CBFS）是康奈尔大学开展水生研究的核心野外基地，其隶属于康奈尔大学农业与生命科学学院自然资源系，更多相关信息可访问http://cbfs.dnr.cornell.edu/index.html。该站科研项目的核心是一项历时60年的纽约奥奈达湖食物网数据库，其构建得到了康奈尔大学布朗捐赠基金以及纽约州环境保护部的资助。本数据集相关数据均由康奈尔大学生物野外站工作人员采集，涵盖湖沼学、底栖生物、浮游动物、浮游植物以及鱼类调查数据，采集范围以奥奈达湖为主，时间跨度为1957年至今。本数据包收录了纽约奥奈达湖浮游植物的调查结果，分为两个数据序列：1975年至1995年，以及1996年至今。主数据表列出了从奥奈达湖各采样点采集的样本中鉴定出的浮游植物类群密度。其中5个采样点为标准采样点，用于合并站点数据时使用。衍生数据表则给出了1975年至1995年期间，5个标准采样点各类群浮游植物的平均密度与生物体积。补充数据表则对两个主数据表中使用的类群编码进行说明，并提供各采样点的地理坐标及相关信息。
