Chapter 14: First Light

The sun returned on February 14th. This was a coincidence of the calendar, the orbital mechanics of the earth's tilt aligning with the human convention of Valentine's Day, the day that the culture designated for the celebration of love, and the people of Longyearbyen observed both occasions — the astronomical and the romantic — with equal enthusiasm, because in a place where the sun's absence was a lived experience rather than a theoretical concept, the sun's return was an event that carried genuine emotional weight, a restoration of something essential, a recovery of a condition that had been lost, and the fact that it fell on a day already dedicated to love gave the event a resonance that was sentimental and irresistible and that even Astrid, who did not trust sentiment, could not entirely dismiss.

The community gathered on the steps of the old hospital, the traditional viewing point, the spot where the line of sight to the south was unobstructed and where the low ridge of the mountains that defined the southern horizon was visible, the ridge over which the sun would appear, briefly, at 11:58 a.m., for a duration of one minute and thirty-seven seconds before it set again, the first appearance a rehearsal, a preview, a promise that the longer days were coming, that the light was returning, that the four months of darkness were ending and the four months of increasing light were beginning and the world was going to be visible again, in full color, in three dimensions, the landscape restored to its full complexity after the simplified, monochrome months of the polar night.

Astrid and Erik walked to the hospital steps together. The town was out. Two hundred, three hundred people, gathered on the steps and the road and the hillside above, all of them facing south, all of them looking at the same point on the horizon, the same notch between two mountains where the calculations said the sun would appear, the collective attention focused on a single point in space with an intensity that was almost devotional, the entire community turned toward the light like a field of sunflowers, the phototropism of human longing, the biological imperative to seek the light that sustained all living things.

The sky above the mountains was orange. The color deepened as noon approached, the gradient shifting from pale yellow at the horizon to deep orange to pink to the blue of the upper sky, the colors layered like strata in rock, each layer a different temperature of light, the warm colors near the horizon where the sun was closest and the cool colors above where the atmosphere was thinner and the light scattered differently. Astrid watched the gradient and thought about temperature, about the gradient of cold in the tunnel, the air warming as you walked outward, each zone lighter and warmer than the last, and the comparison was apt in a way she did not pursue, the comparison between leaving the dark and entering the light, between emerging from the mountain and stepping into the world, between the conditions of preservation and the conditions of life.

Erik stood beside her. He wore the blue jacket she had bought him for Christmas three years ago, the insulated parka with the fur-trimmed hood that he never pulled up because he liked the cold on his face, liked the sting of the air, liked the physical evidence of the climate they lived in, the daily confirmation that they were in a place where the conditions were extreme and real and non-negotiable. She looked at him and he looked at the horizon and she reached for his hand and found it and held it and the holding was different from the holding in the hallway at the solstice party, different from the accidental contact of two people passing in a kitchen, different from the habitual touch of a long marriage. The holding was intentional. The holding was a choice. The holding was the physical expression of the conversation they had been having for two weeks, the conversation that had opened the coat and let the water in, the conversation that had changed the conditions inside their marriage the way imbibition changed the conditions inside a seed, the dry becoming wet, the hard becoming soft, the dormant becoming active.

The sun appeared.

It came over the ridge as a point of light, then a sliver, then a narrow arc, and the arc was so bright after four months of darkness that Astrid's eyes watered and she squinted and the squinting did not diminish the intensity but concentrated it, the light entering her eyes in a compressed beam that reached the retina with a force that was physical, that was felt in the body as well as in the vision, the physiological response to light after prolonged deprivation, the nervous system recognizing the signal, the serotonin production activating, the melatonin suppression beginning, the body's chemistry shifting in response to the information that the light carried: the sun is back, the day is starting, the conditions are changing.

The crowd made a sound. Not a cheer, not an applause, but a sound, a collective exhalation, a murmur that was part relief and part joy and part the simple, uncontrollable vocalization of a group of people experiencing the same thing at the same time, the shared response to a shared stimulus, the community functioning as a single organism for a moment, oriented in the same direction, feeling the same feeling, the differences between them — nationality, profession, age, language, the specific contours of each individual life — temporarily irrelevant, dissolved in the shared experience of the light.

The sun was orange and flat and barely above the ridge and it lasted for one minute and thirty-seven seconds and then it set, slipping behind the mountains again, returning to the place below the horizon where it had spent the past one hundred and eleven days, and the sky held the afterglow for twenty minutes, the gradient fading from orange to pink to purple to blue to the deep blue-gray of the ongoing twilight, and the crowd dispersed, people returning to their offices and their homes and their routines, carrying the light with them in their retinas and their moods and their conversations, the first sunrise a shared reference point, a collective memory, a thing they had witnessed together and that they would talk about for the rest of the day and the rest of the week, the way communities talked about all shared events, the talk reinforcing the memory, the memory reinforcing the community, the community reinforcing the decision to be here, in this place, at this latitude, where the sun went away and came back and the absence gave the return a meaning that people in temperate latitudes, where the sun rose every day without exception, could not understand.

Astrid and Erik walked home. The walk was fifteen minutes and they walked in the afterglow, the sky still bright enough to see by, their headlamps off for the first time in months, the road visible in the natural light, the buildings casting faint shadows, the fjord a sheet of pewter below the mountains. They walked in the silence that was a different silence from the silences of the polar night, a silence that was warm rather than cold, full rather than empty, the silence of two people who had said the things they needed to say and who were now in the space after the saying, the space where the words settled and the feelings organized themselves and the future, which had been abstract, began to take shape.

"I'll tell Lars on Monday," Astrid said.

Erik looked at her. "About Bergen?"

"About the leave. August to December. Five months."

"You're sure?"

She was not sure. Sure was not a state she inhabited. Sure was the state of a seed that had been tested and verified and assigned a viability percentage of ninety-eight, a seed that could be relied upon to germinate, to grow, to produce the expected result. Astrid's viability was not ninety-eight percent. Astrid's viability was uncertain, was untested, was the viability of a seed that had been in storage for a long time under conditions that were not optimal, a seed whose capacity for growth was unknown and that could only be determined by planting, by placing the seed in soil and adding water and waiting and seeing whether the radicle emerged, whether the shoot extended, whether the coat was breached and the embryo responded and the life that had been dormant began to move.

"I'm not sure," she said. "But I'm going."

The distinction mattered. The distinction between sure and going was the distinction between certainty and action, between knowing the outcome and accepting the risk, between the viability test on the agar plate and the planting in the field. The test told you the percentage. The planting told you the reality. And the reality was always more complex than the percentage, was always influenced by factors the test could not control — the soil, the weather, the pests, the diseases, the thousand variables that the field introduced and that the laboratory excluded, the messy, uncontrolled, beautiful, dangerous conditions of the actual world.

They went inside. The apartment was warm. The light from the kitchen lamp was yellow and steady and insufficient and Astrid turned on the living room lamp as well, and the additional light filled the room with a warmth that was more psychological than thermal, the reassurance of visibility, of being able to see the space she occupied, the furniture and the shelves and the photograph on the wall and the philodendron on the windowsill, the plant that had survived eight Arctic years in a pot on a ledge, growing toward whatever light came through the glass, bending and stretching and adjusting, the long, slow tropism of a living thing orienting itself toward the conditions it needed, adapting to the conditions it had.

She sat at the desk and drafted the leave request. The language was institutional, formal, the language of human resources and personnel management: "I hereby request a leave of absence from my position as Seed Vault Coordinator for the period August 1 to December 31, for purposes of personal development and accompanying my spouse on an academic sabbatical in Bergen." Personal development. The phrase was a container, like a seed packet, that held a larger reality in a smaller space, the reality being that she was leaving the vault for the first time in eight years, leaving the tunnel and the chamber and the minus eighteen degrees, leaving the mountain that had been her workplace and her refuge and her hiding place, leaving the conditions of preservation for the conditions of life.

She saved the draft. She did not send it. She would send it on Monday, after talking to Lars, after arranging the details, after confirming the logistics that would allow her absence without disrupting the vault's operations. The vault would continue without her. This was its design. The vault was built to function passively, to maintain its conditions without human intervention, to persist even if the staff left and the office closed and the institution that managed it ceased to exist. Lars and Kari could handle the daily operations. The monitoring system would alert NordGen to any deviations. The compressors would run and the temperature would hold and the seeds would remain dormant and viable and the vault would do what the vault did, whether Astrid was there or not.

The realization was both liberating and deflating. Liberating because it freed her to leave. Deflating because it revealed what she had been avoiding: the vault did not need her. The vault needed maintenance, needed monitoring, needed the daily care that any facility required, but it did not need her specifically, her attention, her devotion, her daily walks through the tunnel, her minutes in the chamber, her relationship with the seeds on the shelves. The vault was indifferent to the identity of its keeper. The vault would accept any competent custodian. The vault did not know her name.

This was the difference between the vault and a life. A life needed specific people. A life was composed of relationships that were not interchangeable, that depended on the particular, the individual, the irreplaceable. Erik was not interchangeable. Lars was not interchangeable. Fatima was not interchangeable. The baby Signe was not interchangeable. The people in Astrid's life were specific and particular and the connections between them were connections that could not be maintained by a substitute, could not be preserved by a system, could not be kept at minus eighteen degrees and retrieved when needed. The connections were alive or they were dead. They grew or they did not. They required the conditions of growth — warmth, attention, presence, vulnerability, the willingness to be changed by the relationship — and the conditions of growth were the opposite of the conditions of preservation, were warm where the vault was cold, were variable where the vault was constant, were risky where the vault was safe.

She stood at the window. The afterglow was gone. The sky was dark again, the stars visible, the aurora faint in the north, a green shimmer that pulsed and faded, pulsed and faded, the rhythm of the solar wind, the heartbeat of the sun reaching across ninety-three million miles of space to touch the earth's atmosphere and produce the light that the people below watched and named beautiful. She looked at the aurora and she thought about Fatima's wheat growing in Morocco, fifteen plants in fifteen pots, the shoots extending, the leaves unfurling, the roots pushing into the soil, the plants doing what plants did, what they had always done, what the seeds in the vault were waiting to do, what everything that was alive was either doing or waiting to do: grow.

She closed the curtain. She turned from the window. Erik was reading on the sofa, the lamp above him casting a warm circle of light that included the sofa and the coffee table and the edge of the rug and that faded at the margins into the dimmer light of the room, the boundary between light and dark soft and gradual, a gradient rather than a line, and she walked across the room and sat beside him and he shifted to make space for her and she leaned against him and his arm came around her shoulders, the gesture automatic and deliberate at the same time, habitual and chosen, the product of fifteen years of practice and of the decision, renewed in this moment, to continue.

"Tell me about the cod," she said.

He looked at her, surprised by the question not because it was unusual — she asked about his work regularly — but because of the way she asked it, the tone different, the attention different, the quality of the asking different from the routine professional check-in that their work conversations usually were. She was not asking about data. She was asking about him. She was asking to hear his voice talking about the thing he cared about, the thing that animated him, the thing that brought him to the fjord every morning and out onto the water in the cold and the dark, the passion that was his equivalent of her vault, his relationship with the living world, his commitment to understanding the things in his care.

He told her. He told her about the polar cod's migration, about the acoustic tags that tracked their movement through the fjord, about the temperature data that showed the warming and the fish that responded to the warming by moving north, toward colder water, toward the conditions they needed, the conditions they were adapted to, the conditions that were receding, moving away from them at a rate that was faster than their capacity to follow. He told her about the Atlantic cod that were moving into the space the polar cod left behind, the temperate species replacing the Arctic species, the slow-motion rearrangement of the marine ecosystem that was, in its way, a kind of displacement, a kind of loss, a kind of change that was not reversible and that was producing a world that was different from the world that had existed before, a world that would require its inhabitants to adapt or to move or to wait for conditions that might not return.

She listened. She listened the way she had not listened in years, with the full attention that she usually reserved for the vault, the attention that was not distracted by the accession database or the temperature logs or the mental inventory of the chamber's contents but that was here, on this sofa, with this man, listening to his voice describe the movement of fish through cold water, the science of it, the beauty of it, the concern of it, the love for the subject that was audible in every sentence, the passion that she had fallen in love with fifteen years ago at a conference in Trondheim and that she heard now, again, as if for the first time, the voice new because the listening was new, the words different because the conditions were different, the conversation changed because the coat had been breached and the water had entered and the dry interior was swelling and softening and the embryo, the living center, was beginning, tentatively, cautiously, irreversibly, to grow.

Outside, the dark held. But the dark was not as dark as it had been. The sun had appeared for one minute and thirty-seven seconds and it would appear again tomorrow for longer and the day after for longer still and the light was coming, was returning, was building in the increments that the earth's orbit prescribed, the slow, certain, astronomical progression from dark to light, from winter to spring, from the conditions of dormancy to the conditions of growth, and in ten days the twilight would last for hours and in a month the sun would be above the horizon for half the day and in two months the snow would begin to melt and the first flowers would appear on the hillsides, the Arctic poppies and the purple saxifrage that bloomed in June, the first color after months of white, the first evidence that the landscape was alive, that it had been dormant and not dead, that the cold had preserved rather than destroyed, that the life that had been invisible was still there, waiting, beneath the snow, beneath the ice, beneath the surface, ready to emerge when the conditions allowed, ready to grow, ready to bloom, the way all dormant things were ready, the way the seeds in the vault were ready, the way Astrid was ready, or was becoming ready, or was beginning to allow herself to consider the possibility that readiness was a state she could inhabit, that growth was a process she could undergo, that the conditions she had been waiting for were not a temperature or a protocol or a set of numbers on a screen but a conversation with the person beside her and a decision to leave the mountain and a willingness to let the light in.
