Microplankton counts from discrete water column samples using flow imaging microscopy (FlowCam) from Lakes Fryxell and Hoare, McMurdo Dry Valleys, Antarctica (2007-2011)

This data package consists of microplankton counts from discrete water column samples collected at various depths in Lake Fryxell and Lake Hoare in the McMurdo Dry Valleys region of Antarctica. Samples were collected and preserved during the austral summer-autumn transition in 2007-2008 and in addition to routine McMurdo Dry Valley Long Term Ecological Research (LTER) core limnological sampling in November and December of 2008, 2010, and 2011. Data were imaged using flow cytometry (FlowCam VS-IV) and classified with statistical image-based software (Visual Spreadsheet, v4.17.14). These data include haptorian ciliates, filamentous cyanobacteria, and coccoidal algae particle counts per milliliter that were automatically classified from user-built libraries and statistical filters based on the morphological characterizations of the plankton.

本数据包涵盖南极麦克默多干谷（McMurdo Dry Valleys）地区弗莱克塞尔湖（Lake Fryxell）与霍尔湖（Lake Hoare）中不同水深采集的离散水柱样本的微型浮游生物计数数据。样本于2007-2008年南极夏秋季转换期采集并固定，同时还包含2008年、2010年及2011年11—12月开展的常规麦克默多干谷长期生态研究（Long Term Ecological Research，LTER）核心湖沼学采样数据。数据采用流式细胞术（flow cytometry）结合FlowCam VS-IV设备完成成像，并通过基于统计的图像分析软件Visual Spreadsheet（v4.17.14）进行分类。本数据集包含每毫升样本中的定鞭纤毛虫（haptorian ciliates）、丝状蓝细菌（filamentous cyanobacteria）以及球藻藻类颗粒的计数结果，上述分类均基于浮游生物的形态特征，通过用户自建的参考库与统计过滤器自动完成。
