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并实现一种经济高效且易于操作的多岩石覆盖和深海相机系统，该系统将广泛应用于海底成像和采样。它将在联卢观察团的研究船上提供。该系统的核心是基于标准CTD设备和。322”同轴导电电缆和绞车，这是联索特派团所有船只和技术人员所熟悉的。多覆盖/相机的目的是在降低过程中拍摄多个核心，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记录数码相机系统、用于触发每个井盖的CTD塔、压力传感器和高度计，这些通常与CTD单元集成在一起，用于确定离底深度高度。多覆盖/相机将允许每次下潜拍摄20个岩心，每10秒拍摄一张数字照片。成像系统将很容易转换为光纤水文电缆，一旦光纤水文电缆被引入联索特派团船上，就可以将图像直接遥测到地面。

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.
