This ocean science technology development project will design and implement a cost-efficient and easy-to-operate, multiple rock corer and deep sea camera system that will have wide application for ocean floor imaging and sampling. It will be made available on UNOLS research vessels. The core of the system is based on standard CTD equipment and .322" coaxial conducting cable and winches which are familiar to all UNOLS ships and technicians. The purpose of the multi-corer/camera is to take multiple cores during a lowering while at the same time collecting digital photographs of the seafloor being sampled. The system uses a proven self-recording digital camera system, a CTD pylon for triggering each corer, and a pressure sensor and altimeter, that are commonly integrated with CTD units for determining depth altitude off bottom. The multi-corer/camera will permit 20 rock cores to be taken on each lowering, with digital photographs taken every ~10 sec. The imaging system will be easily transformable for use with a fiber optic hydrographic cable and direct telemetry of the images to the surface once fiber optic hydrographic cables are introduced on UNOLS ships.

这一海洋科学技术开发项目将设计和实施一个具有成本效益和易于操作的多岩石取样器和深海照相机系统，该系统将广泛应用于海底成像和取样。 将在联合国后勤处的研究船上提供。该系统的核心是以标准CTD设备和.322”同轴电缆和绞盘为基础，这些都是联合国地雷行动处所有船只和技术人员所熟悉的。多芯取样器/照相机的目的是在下放过程中采集多个岩心，同时收集正在取样的海底的数码照片。该系统使用一个经过验证的自记录数码相机系统、一个用于触发每个取芯器的CTD挂架、一个压力传感器和高度计，这些传感器和高度计通常与CTD装置集成在一起，用于确定离海底的深度高度。多芯取样器/照相机将允许每次下放时采集20个岩心，每10秒采集一次数码照片。 一旦在联合国日内瓦办事处的船只上安装了光纤水文电缆，成像系统将很容易转换，与光纤水文电缆一起使用，并将图像直接遥测到水面。
