SAIMOS - Biological and Flow Cytometry data collected from CTD stations in South Australia, in September 2017

Flow cytometry data was collected in September 2017, in waters off South Australia. The general purpose of the study is to be able to establish background knowledge on the ecosystem on the continental shelf of South Australia and the impact of upwelling/saline outflow events on microbial communities to ultimately develop a biogeochemical model of the region. Sampling was carried out during cruises conducted on board the RV Ngerin as part of the Southern Australian Integrated Marine System (SAIMOS). During each cruise, the physical, chemical and biological properties of the chlorophyll fluorescence maximum (DCM) layer were investigated. Flow cytometry data has been collected for picophytoplankton, bacteria and viruses.Six main stations have been sampled over the course of the study, five are located on the 100 m isobath, i.e. RS (35.508S, 136.278E), B2 (35.418S, 136.148E), B3 (35.258S, 136.048E), SAM2CP/B4 (35.168S, 135.418E) and SAM5CB/B5 (35.008S, 135.198E), and one from an offshore station (B1; 36.188S, 136.178E) located southwest of Kangaroo Island. Note that combining the distances between stations (14–25 nautical miles), the average component of the current velocity at middepth along the shelf (0.01 m s21) and the average speed of the vessel (i.e. 9 knots) indicate that different water masses were sampled at each station. Additional samples have on occasion been collected from the National Reference Station (NRS) at Kangaroo Island (35.832S, 136.447E) and the SA Spencer Gulf Mouth Mooring (SAM8SG, 35.25S, 136.690E), where the saline outflow occurs.

本数据集的流式细胞术数据采集于2017年9月，采集区域为澳大利亚南部近海海域。本研究的总体目标为：建立澳大利亚南部大陆架海域生态系统的背景知识体系，阐明上升流与咸水流出事件对微生物群落的影响，最终构建该区域的生物地球化学模型。
采样工作依托‘恩格林号’科考船（RV Ngerin）开展，作为澳大利亚南部综合海洋系统（Southern Australian Integrated Marine System, SAIMOS）项目的组成部分。每次科考航次中，均对叶绿素荧光最大值层（Deep Chlorophyll Maximum, DCM）的物理、化学与生物学特性展开调查。本数据集已针对超微型浮游植物、细菌与病毒采集了流式细胞术数据。
本研究共布设6个主要采样站位：其中5个站位位于100米等深线处，分别为RS（35.508°S，136.278°E）、B2（35.418°S，136.148°E）、B3（35.258°S，136.048°E）、SAM2CP/B4（35.168°S，135.418°E）以及SAM5CB/B5（35.008°S，135.198°E）；剩余1个为离岸站位B1（36.188°S，136.178°E），位于袋鼠岛西南海域。
注：结合站位间距离（14至25海里）、陆架中层海流的平均流速分量（0.01 m·s⁻¹，原文笔误为s21）以及科考船平均航速（约9节），可推断各站位采集的水团并不相同。
研究期间还偶尔于袋鼠岛国家参考站（National Reference Station, NRS，35.832°S，136.447°E）以及SA斯宾塞湾口锚泊站（SA Spencer Gulf Mouth Mooring, SAM8SG，35.25°S，136.690°E）采集了额外样本，上述两处均为咸水流出事件发生区域。
