A Deep-Sea Multiple Rock Corer and Self-Recording Digital Camera System with UNOLS Standard CTD Triggering Controls

该海洋科学技术开发项目将设计和实施一种低成本、易操作的多岩石取样器和深海相机系统，将在海底成像和采样方面有广泛的应用。它将在联合国日内瓦办事处的考察船上提供。该系统的核心是标准的CTD设备和.322英寸同轴电缆和绞盘，这些都是联合国内罗毕办事处所有船只和技术人员所熟悉的。多取样器/照相机的目的是在下沉过程中采集多个岩心，同时收集被采样海底的数字照片。该系统使用经过验证的自我记录数码相机系统、用于触发每个取样器的CTD塔架、压力传感器和高度计，它们通常与CTD单元集成在一起，用于确定海底的深度和高度。多功能取心器/照相机将允许在每次下井时拍摄20个岩石岩芯，每隔10秒拍摄一次数字照片。一旦联索办事处船只上安装了光纤水文电缆，成像系统将很容易改装，以便与光纤水文电缆一起使用，并可直接遥测图像到水面。

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.
