You activate your full-spectrum visual sensors, as well as a sonar imaging sensor which allows you to "see" with both ambient sound and pulses of sound which you generate. In the distance you detect a concentrated source of infrared radiation -- the electromagnetic evidence of something much hotter than the frigid water in which you now hold your position.

Unfortunately, your attitude needs adjusting; you have somehow rolled 90 degrees onto your side. The automatic pilot strives to stabilize in the strong, turbulent bottom current, activating quick sequences of the 6 microthrusters which propel your sphere. The current carries you closer to the infrared radiation source before your position steadies.

Slowly, the crimson digital display begins to tabulate readings from your many scientific instruments. Your depth is 2280 meters. You are hovering 1 meter above the sea floor. While the deep sea water around you is mostly typical, occasionally the temperature, salinity, and chemical compostion of the water suddenly vary. You observe that the sea floor is not completely covered with sediments, as it usually is in deeper parts of the ocean. Indeed, in some nearby areas, there is only a dusting of rust-colored sediments over exposed patches of lustrous black stone.


Slowly, the nanocomputers correct the roll, and you are faced with an array of choices:
