He elaborated, “While we were able to collect the 'golden orb' and bring it onto the ship, we still are not able to identify it beyond the fact that it is biological in origin. We likely won't learn more until we are able to get it into a laboratory setting where we can continue to pull from the collective expertise of the scientific community with more sophisticated tools than we are able to maintain on the ship. While somewhat humbling to be stumped by this finding, it serves as a reminder of how little we know about our own planet and how much is left to learn and appreciate about our ocean.”

... it's still unclear if the golden dome is associated with a known species, a new species, or perhaps represents an unknown life stage of an existing one
