Jason Virtual Van

Jason is a remotely operated vehicle (ROV) deep-diving vessel that gives shipboard scientists immediate, real-time access to the sea floor. Jason is connected by a long fiberoptic tether to its research ship. The 10-km (6 mile) tether delivers power and instructions to Jason and fetches data from it. As part of the Jason ROV project, the Virtual Van data acquisition system was developed to automatically captures the information in the control-van during ROV operations including up to four simultaneous video sources, vehicle data, scientific instrument data, and event data. All this information is accessible via a web-browser in real-time and is also available to the scientists after the cruise for post-cruise data access and analysis.

Jason是一款远程操控潜水器（remotely operated vehicle, ROV）深潜载具，可为船载科研人员提供实时直达的海底观测通道。Jason通过一条长10千米（约6英里）的光纤系缆与母科研船相连，该系缆可为其输送电力、传输操控指令并回传采集到的数据。作为Jason ROV项目的组成部分，研发团队开发了Virtual Van数据采集系统，可在ROV作业期间自动捕获操控舱内的各类信息，包括最多四路同步视频信号、载具状态数据、科学仪器数据及事件日志数据。所有此类信息均可通过网页浏览器实时访问，且航次结束后，科研人员也可获取这些数据用于航后数据访问与分析。
