使用自主视觉浮游生物记录仪(AVPR)记录了世界各地多个寡营养站的浮游生物和其他海洋颗粒物的原位彩色图像,包括北半球副热带公海、南半球热带边缘海、北半球副热带边缘海和极地公海。在确定最佳图像增强设置并在现成的图像分析软件 Image Pro Plus 中使用专门开发的宏例程后,可以对颗粒浓度、尺寸和垂直轮廓进行定量分析和比较。介绍并讨论了海洋颗粒分布、它们与海洋学参数和水团结构的关系以及系统的分辨率相关限制。
An Autonomous Visual Plankton Recorder (AVPR) was used to record colour in situ images of plank- ton and other marine particulates at several oligotrophic stations around the world, including a northern hemi- sphere subtropical open ocean, a southern hemisphere tropical marginal sea, a northern hemisphere subtropical marginal sea, and a polar open ocean. Quantitative analyses and comparisons of particle concentrations, sizes and vertical profiles were possible after identification of optimal image enhancement settings and employment of a specially-developed macro routine in the off-the-shelf image analysis software Image Pro Plus. Marine particulate profiles, their relationships to oceanographic parameters and water mass structure, and the resolution-dependent limitations of the system are introduced and discussed.
