From Halopedia, the Halo wiki
Project: ALOHA-19 was a Unified Earth Government initiative which involved the artificial intelligence Gabriela and her supervision of an Outpost Discovery following the end of the Human-Covenant War.
As part of Project ALOHA-19, an Acheron Security A.I. memory matrix containment and display module was shipped from Havenwinter on Ballast to UNSC Transit Dock L22 on Luna, and from there to an Outpost Discovery on Earth. This module was used to contain and display the avatar of Gabriela, the A.I. caretaker of the Outpost Discovery. Gabriela's operating system was at least partially designed in accordance with the project as well, being labelled "ALOHA 1.0".
