Winter marine communities of the Antarctic Peninsula

Winter survey data from the Antarctic Peninsula (including hydrography, zooplankton, and top predators) conducted from the R/V Nathaniel B. Palmer during the austral winter (August-September) of 2012-2016. Survey stations were selected from the U.S. Antarctic Marine Living Resources Program's standard grid, approximately 15-20 nm apart covering the region 60° to 64° S and 54° to 63° W. At each station, hydrography and chlorophyll measurements were collected with CTD profilers and Niskin bottles, and macrozooplankton samples were collected using an Isaacs-Kidd Midwater Trawl. Between stations, observers recorded abundance and behavior of top predators (seabirds and marine mammals).

本数据集为2012-2016年南半球冬季（8月至9月），搭载内森尼尔·B·帕尔默号（R/V Nathaniel B. Palmer）科考船于南极半岛海域开展的冬季调查数据，涵盖水文、浮游动物及顶级捕食者相关观测数据。调查站位基于美国南极海洋生物资源项目（U.S. Antarctic Marine Living Resources Program）的标准网格选取，站位间距约15-20海里，覆盖南纬60°至64°、西经54°至63°的海域范围。每个站位均使用CTD剖面仪（CTD profilers）与尼斯金采水器（Niskin bottles）采集水文与叶绿素测量数据，并采用艾萨克斯-基德中层拖网（Isaacs-Kidd Midwater Trawl）采集大型浮游动物样本。在相邻站位之间，观测人员记录了顶级捕食者（海鸟与海洋哺乳动物）的丰度与行为特征。
