Using a new platform which takes a square kilometer of ocean-bottom imagery and parses it out into an easily navigable, compelling user interface, we humbly ask you to help find scientifically relevant items, in order to allow us to outline them for a broad representation of the reef. Then, traverse planning scientists can then use this aggegated data to target, or confirm the interest items for further study. We can't do this kind of science on our own. We need your help today and again when we send humans beyond the surly bonds of Earth.
