This became apparent when looking at the same two GIS overlays in 1995 and then again in 2000. One might infer that the increased human activity is disturbing the seabirds as they nest. In an actual example, sanctuary researchers would closely assess the situation, and if needed, recommend further regulations. With the potential of new discoveries beckoning and a new national commitment to assess and understand our ocean planet, the Sustainable Seas Expeditions promise new knowledge and new ways to gather knowledge over the next five years. Ocean sounds are recorded with a directional hydrophone.
Video cameras allow the pilot to record the dive.
VHF and thru-water communications allow contact with surface support personnel. An Ocean Explorer's Dream DeepWorker 2000 is a one-person submersible about the size of a small car. The sub is driven by a trained pilot who may be a scientist, a technician, an explorer, or even a journalist, teacher, or poet. Eliminating the second occupant from the sub reduces its weight, complexity, and the expense of operation. In addition to DeepWorker's design and life support systems, the sub also uses specialized equipment to document marine life, habitat characteristics, and to monitor physical factors such as temperature, the amount of light penetrating the sea, and water quality.
