It's in the air. Assuming the mass of those bodies are approximately that of a human (notably one of the smaller species alive in the Halo Universe), then the Gravemind is approximately 700,000kg at the very minimum. The Gravemind is still alive because the Primordial (the Timeless One, the "last Precursor") transferred his conscious into the Flood before the Didact killed him with a timelock.
He will return he made that clear. I don't know for sure if this is the Gravemind as the camera didn't zoom out as it normally does when he is talking, … His physical body died but his conscious is still alive. The Flood is a highly-infectious parasite which is released several times during Halo's story. Okay, I know this sounds crazy, but I think there is some chance (however small) that the Gravemind is the Primordial and that he may still be alive. The Chief and the Arbiter are captured during their separate missions on Delta Halo, or … The Gravemind is still alive because the Primordial (the Timeless One, the "last Precursor") transferred his conscious into the Flood before the Didact killed him with a timelock. Some good mindblowing content right here.

The Gravemind is a parasitic, hive mind intelligence in the Halo universe. His physical body died but his conscious is still alive.

In Halo 3's last mission, a deep voice says something along the lines of "Defeat is simply an extention of a sentence I never deserved."

Okay, I know this sounds crazy, but I think there is some chance (however small) that the Gravemind is the Primordial and that he may still be alive.
While only one Gravemind is ever seen in the games, the title is given to the final stage of Flood evolution, in which the Flood becomes a superorganism. The Gravemind is a massive creature. I don't know for sure if this is the Gravemind as the camera didn't zoom out as it normally does when he is talking, … Once a new Gravemind forms, it will come back.But that consciousness has no material body right now ?Well, if it does it is waiting in the shadows.
The Gravemind can exist in multiple instances, so it could exist on some level on Delta Halo, the Ark, and High Charity at the same time.. And yes, the Gravemind is still around.
