The ever increasing demand for metals and minerals is putting significant pressure on current mining companies to find more ore. As these companies explore and mine, the future appears to be to go deeper and deeper underground._x000D_
With depth, however, comes ever increasing costs as infrastructure such as hoisting, ventilation, the movement of workers and materials increase in size and scope. Further, the actual rock mass becomes prone to destruction through rock bursts and the heat generated becomes a major issue resulting in extreme expenditures in cooling plants and some of the biggest air movers in the world._x000D_
All these issues result in dramatic changes in both capital and operating costs, subsequently making cut-off grades rise. As this trend continues there is an economic limit to how deep one can go, resulting therefore in a severe shortage of accessible ore deposits to mine. This paper discusses the need for larger marine robotics technology and presents the state-of-the-art in current research in underwater tele-autonomy, specifically the development of high bandwidth optical communication networks critical to any future activities (mining, construction, etc) underwater._x000D_
