In Situ Ichthyoplankton Imaging System (ISIIS) and oceanographic data collected on board the R/V Point Sur cruise PTS01 in the northern Gulf of Mexico on 2015-11-04

This dataset reports In Situ Ichthyoplankton Imaging System (ISIIS) image segments, classifications, and oceanographic data collected on board the R/V Point Sur cruise PTS01 in the northern Gulf of Mexico on 2015-11-04. The chief scientists for this cruise are Dr. Frank Hernandez and Dr. Monty Graham. The data were collected using a towed in situ imaging just offshore of the Louisiana Bird Foot Delta. The ISIIS collected hydrographic data oceanographic parameters such as depth of the vehicle, temperature, salinity, dissolved oxygen, light levels (PAR), and chlorophyll-a fluorescence of the water, along with in situ images of the plankton. The dataset includes the R codes for the image classification. The data were collected during the day and night, and regions of interest (segments) were extracted and identified for comparison to continuous ADCP measurements collected in the same area. ADCP data is available under GRIIDC Unique Dataset Identifier (UDI) R4.x260.204:0004 (DOI: 10.7266/N7PG1Q49).

本数据集收录了2015年11月4日于墨西哥湾北部，搭载“瑟斯角号”（R/V Point Sur）科考船执行PTS01航次期间采集的原位鱼卵仔鱼成像系统（In Situ Ichthyoplankton Imaging System，ISIIS）图像片段、分类结果及海洋学数据。本航次的首席科学家为弗兰克·埃尔南德斯博士（Dr. Frank Hernandez）与蒙蒂·格雷厄姆博士（Dr. Monty Graham）。数据于路易斯安那鸟足三角洲近海采集，采用拖曳式原位鱼卵仔鱼成像系统（ISIIS）完成。该系统同步采集了载体深度、水温、盐度、溶解氧、光照强度（PAR）、水体叶绿素a荧光等水文与海洋学参数，同时获取了浮游生物的原位图像。本数据集包含图像分类所用的R语言代码。数据于昼夜时段均有采集，研究人员提取并标注了感兴趣区域（图像片段），用于与同一区域获取的连续声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP）测量数据开展对比分析。声学多普勒流速剖面仪（ADCP）数据可通过GRIIDC唯一数据集标识符（Unique Dataset Identifier，UDI）R4.x260.204:0004获取，其数字对象标识符（DOI）为10.7266/N7PG1Q49。
