asked.
âNewly developed alloy. Light, nonreactive, exceptionally strong.â
They reached an intersection and Asher turned left. From the image, Crane had assumed the chief scientist of the National Ocean Service to be in his late sixties, but he was obviously a decade younger. What Crane had taken for age lines was really the weathering of a life spent at sea. Asher walked quickly, and he toted Craneâs heavy bag as if it were nothing. For all his apparent healthiness, however, the man kept his left arm cradled against his side. âThese upper levels of the Facility are a warren of offices and dormitories, and they can be disorienting at first,â he said. âIf you ever get lost, refer to the schematic diagrams at major intersections.â
Crane was impatient to learn more about the medical issues and the dig itself, but he decided to let Asher set the agenda. âTell me about the Facility,â he said.
âTwelve decks high, and exactly one hundred eighty meters per side. Its base is embedded into the matrix of the ocean floor, and a protective titanium dome has been placed over it.â
âI saw the dome on the way down. Thatâs some piece of engineering.â
âIt is indeed. This Facility weâre in sits beneath it like a pea under a shell, and the open space between is fully pressurized. With the dome and our own hull, there are two layers of metal between us and the ocean. And itâs some metal, too: the skin of the Facility is HY250, a new kind of aerospace steel, with a fracture toughness above twenty thousand foot-pounds and a yield strength in the range of three hundred KSI.â
âI noticed the surface of the dome was punctured by a horizontal tube, running inward,â Crane said. âWhatâs the purpose of that?â
âYou must mean the pressure spoke. There are two of them, actually, one on either side of the Facility. Given the water pressure at these depths, the ideal shape would be a perfect sphere. The dome being only one half of an ideal sphere, those two tubesâopen to the oceanâhelp counterbalance the pressure. They also anchor the Facility to the dome. No doubt the propeller-heads on deck seven could give you more details.â
This second hallway they were walking through resembled the first: a ceiling busy with cabling and pipes, lots of closed doors with cryptic labels. âI also noticed a strange object attached to the top of the dome, maybe thirty feet across,â Crane said.
âThatâs the emergency escape pod. Just in case someone accidentally pulls the plug.â Asher laughed as he said thisâan easy, infectious laugh.
âSorry, but I have to ask. That dome around us isnât exactly small. Surely certain foreign governments have taken interest?â
âNaturally. Weâve carefully disseminated a disinformation campaign about a secret research sub that went down at this site. They think weâre involved in reclamation operations. That doesnât stop the occasional Russian or Chinese sub from doing a drive-by, of course, causing our military contingent all sorts of angst.â
They passed by a door with a retinal scanner beside it and a complement of two marines, rifles at their sides, standing guard. Asher didnât offer an explanation, and Crane didnât ask.
âWeâre on deck twelve right now,â Asher went on. âItâs mostly support services for the rest of the Facility. Decks eleven and ten are crew quarters, including the sports complex. Youâre bunking on deck ten, incidentally. Weâve got you sharing a bath with Roger Corbett, the mental health officer. Most rooms share bathsâas you can imagine, space is at a premium. Weâve already got a full complement, and youâre an unexpected addition.â
He paused before an elevator, pressed the button. âDeck nine is crew support. The medical suiteâwhere youâll be
