Vertical distribution measurements of Meroplanktonic gastropod larvae and the environment. A Canadian Healthy Oceans Network Population Connectivity project, PC-06

This dataset was collected in the field (using a plankton pump, CTD, fluorometer and ADCP) for a MSc Thesis and 1 publication. This dataset contains the standardized abundance (count m-3) of meroplanktonic larvae (Margarites spp., Crepidula spp., Astyris lunata, Diaphana minuta, Littorinimorpha, Arrhoges occidentalis, lyanassa spp., Bittiolum alternatum, Nudibranchia), temperature, salinity, density, fluorescence, calculated Richardson number and current velocities (north-south, east-west, and vertical velocities) at 6 (3, 6, 9, 12, 18 and 24 m) depths, every 2 h over a 36- and 26-h sampling period, in St. George’s Bay, Nova Scotia, Canada. The dataset also included lunar cycle, diel period, tidal state, date, time, sampling depth, sampling depth range, and more.

本数据集为完成一篇硕士学位论文及1篇学术出版物而在野外采集获取，采集所用设备包括浮游生物泵、温盐深仪（CTD）、荧光计及声学多普勒流速剖面仪（ADCP）。该数据集涵盖加拿大新斯科舍省圣乔治湾（St. George’s Bay, Nova Scotia, Canada）的多类观测数据：其一为阶段性浮游幼虫（meroplanktonic larvae）的标准化丰度（单位：个·m⁻³），涉及星螺属（Margarites spp.）、履螺属（Crepidula spp.）、阿斯泰里斯螺（Astyris lunata）、小笛螺（Diaphana minuta）、玉黍螺目（Littorinimorpha）、西方翁戎螺（Arrhoges occidentalis）、蛾螺属（Iyanassa spp.）、交替小锥螺（Bittiolum alternatum）及裸鳃目（Nudibranchia）；其二为环境参数，包括水温、盐度、密度、荧光值、计算得到的理查森数（Richardson number），以及北-南向、东-西向与垂向的流速。本次采样共设置6层水深，分别为3 m、6 m、9 m、12 m、18 m及24 m，采样间隔为每2小时1次，采样时长分别为36小时与26小时。此外，数据集还包含月相周期、昼夜时段、潮汐状态、日期、时间、采样深度、采样深度范围等额外元数据。
