Blue Mars(98)

TEMPE TERRA



She walked the shore of the new sea. It was at the foot of the Great Escarpment, in Tempe Terra, a lobe of ancient highlands extending into the north. Tempe had probably escaped the general stripping of the northern hemisphere by being roughly opposite the impact point of the Big Hit, which most areologists now agreed had struck near Hrad Vallis, above Elysium. So; battered hills, overlooking an ice-covered sea. The rock looked like a red sea’s surface in a wild cross chop; the ice looked like a prairie in the depths of winter. Native water, as Michel had said— there from the beginning, on the surface before. It was a hard thing to grasp. Her thoughts were scattered and confused, darting this way and that, all at the same time— it was like madness, but not. She knew the difference. The hum and keen of the wind did not speak to her in the tones of the MIT lecturer; she suffered no choking sensations when she tried to breathe. It was not like that. Rather her thinking was accelerated, fractured, unpredictable— like that flock of birds over the ice, zigzagging across the sky in a hard wind from the west. Ah the feel of that same wind against her body, shoving at it, the new thick air like a great animal paw. . . .

The birds struggled in it with reckless skill. She stood for a while and watched: they were skuas, out hunting over dark streaks of open water. These polynyas were just the surface signs of immense pods of liquid water under the ice; she had heard that a continuous channel of under-ice water now wrapped the globe, winding east over old Vastitas, tearing frequent polynyas in the surface, gaps which then stayed liquid for an hour or a week. Even with the air so cold, the underwater temperatures were warmed by the drowned Vastitas moholes, and rising heat from the thousands of thermonuclear explosions set off by the metanats around the turn of the century. These bombs had been placed deep enough in the megaregolith to trap their radioactive fallout, supposedly, but not their heat, which rose in a thermal pulse through the rock, a pulse that would continue for years and years. No; Michel could talk about it being Mars’s water, but there was little else that was natural about this new sea.

Ann hiked up a ridge to get a wider view. There it lay: ice, mostly flat, sometimes shattered. All as still as a butterfly on a twig, as if the whiteness might suddenly lift off and fly away. The birds’ wheeling and the clouds’ scudding showed how hard the wind blew, everything in the air pouring east; but the ice remained still. The wind’s voice was deep and huge, scraping over a billion cold edges. A strip of gray water was striated by windchop, the strength of each gust precisely registered by the flayed cat’s paws, each brush of harder wind feathering the larger waves with exquisite sensitivity. Water. And below that brushed surface, plankton, krill, fish, squid; she had heard they were producing in hatcheries all the creatures of the extremely short Antarctic food chain, and then releasing them to the sea. Teeming water.

The skuas wheeled overhead. One cloud of them whirlpooled down onto something along on the shore, behind some rocks. Ann hiked toward them. Suddenly she saw the birds’ target, lying in a cleft at the edge of the ice: the mostly eaten remains of a seal. Seals! The corpse lay on tundra grass, in the lee of a patch of sand dunes, sheltered by another rocky ridge running down into the ice. The white skeleton emerged from dark red flesh, ringed by white blubber, black fur. All torn open to the sky. Eyes pecked out.

She hiked on past the corpse, up another little ridge. The ridge made a kind of cape extending into the ice, and beyond it was a bay. A round bay— a crater, infilled by ice. It had happened to lie at sea level, had happened to have a breach in its rim on its seaward side, so that water and ice had poured in and filled it. Now a round bay, perfect for a harbor. One day it would be a harbor. About three kilometers across.

Ann sat down on a boulder on the cape, and looked out at the new bay. Her breath heaved in and out of her in an involuntary motion, her rib cage moving violently, as during labor contractions. Sobs, yes. She pulled aside her face mask, blew her nose using her finger, wiped her eyes, all the while still weeping furiously. This was her body. She recalled the first time she had stumbled onto the flooding of Vastitas, in a solo trip ages ago. That time she had not cried, but Michel had said that was only shock, the numbness of shock, as in any injury— withdrawal from her body and her feelings. Michel would call this response healthier, no doubt, but why? It hurt— her body, spasming in a seismic trembling. But when it was over, Michel would say, she would feel better. Drained. A tension gone— the tectonics of the limbic system— she scorned such simplistic analogies as Michel offered, the woman as planet, it was absurd. Nevertheless there she sat, sniffling, looking out at the ice bay under scudding clouds, feeling drained.
