Film helps document the world, but Oscar-nominated filmmaker Sarah Dosa’s new project with National Geographic asks audiences to feel its rhythms, ruptures, and responsibilities. The documentary, Time and Water, explores how humans seek meaning with the more‑than‑human natural world, using Iceland’s glaciers and one family’s archive to examine time, memory, and ecological care. Her new film treats nature as a collaborator with its own intelligence and history.
At a moment when climate narratives can highlight doom and catastrophe, Dosa offers a different cinematic tone. She builds a story that acknowledges loss while insisting on possibility. Her approach blends science, myth, and intergenerational memory to reframe how viewers imagine the future. It is a film about glaciers, but more about the stories we choose to carry forward.
Her work stems from the awe she felt growing up among redwoods and the Pacific, which shaped her sense of scale and responsibility and recognition in the power of the ocean. That early connection still guides her,and also grounds her belief that stories can help people act with more care toward the planet.
Building a Polytemporal Film
Time is the film’s central material. Not a straight line, but a layered field. Doja and her team built a structure that collapses centuries into a single cinematic rhythm by using archival footage from the 1930s, family photographs, and Icelandic manuscripts from around 1200. These fragments sit beside contemporary glacier footage, creating a collage that resists linearity and invites viewers to experience time as something textured and alive.
This approach challenges the idea that time only moves forward toward collapse. Instead, the film suggests that nature’s rhythms echo across generations, much like the Icelandic rimur that inspired the project’s structure. The film uses these echoes to show how environmental change disrupts ancient patterns. “Our hope was to posit a different form of time that works and rhymes,” said Doja.
The nonlinear structure also reframes the climate crisis. Yes, it becomes a countdown; moreover, it acts as a rupture in a long conversation between people and place. By weaving past and present together, the film highlights what remains worth fighting for. Meanwhile, it shows how human and planetary memory can guide future action for this era of climate crisis.
The Power of an Intergenerational Lens
To make these ideas accessible, Doja centers the story on Andri Magnason and his family. Their archive becomes a bridge between personal memory and planetary change. The intergenerational narrative helps viewers visualize time in human terms, grounding vast ecological concepts in familiar relationships. It also avoids the dystopian tropes that dominate climate storytelling.
Andri’s idea of the “handshake of generations” anchors the film. The image of a child today becoming an elder who speaks to another child in the future offers a simple way to imagine continuity. It also reframes responsibility as something shared across time. “You have a way of visualizing the future beyond these tropes of dystopia,” explained Doja. The film uses this lens to show how care can move forward.
The story remains intimate, but its resonance is broad. By focusing on one family’s archive, the film invites audiences to consider their own. It asks viewers to reflect on the futures they imagine for the people they love and also suggests that understanding where time fractures can help us understand how to repair it.
Working with myth and allegory carries risks. Doja and her team approached these themes with care, especially when dealing with Andri’s family history. They wanted to avoid reducing personal suffering to metaphor; more importantly, they wanted to avoid flattening the emotional complexity of climate loss. The film’s power comes from its sensitivity instead of its symbolism.
The parallel between Andri’s grandfather’s fading memory and the melting of Iceland’s glaciers is one of the film’s most striking elements. Both hold histories, yet they are slipping away. But Doja insists the film does not present this as a puzzle to decode. The team worked to protect that vulnerability while still inviting viewers to form their own associations. “It’s a really vulnerable thing to put your family’s story on film,” she said.
This balance required constant conversation. The filmmakers discussed where association becomes instrumentalization and how to maintain compassion in the storytelling. The result is a film that honors human and planetary memory simultaneously without collapsing one into the other. It treats loss as something shared, and certainly not as something interchangeable.

Water as Cinematic Language
Water appears in every form throughout the film. Fog. Rivers. Ice. Sea. Each becomes a character. Much of this comes from cinematographer Pablo Alvarez‑Mesa, whose previous work treated water with similar reverence. His patience and attention allow the camera to capture nature’s intelligence rather than its spectacle.
Doja describes Pablo as someone who can “get so in tune with clouds, with the ice, with the birds,” which allows his sensitivity to shape the film’s visual language. It also reinforces the idea that glaciers are not static objects but living presences with their own rhythms. The imagery gives viewers a sense of the glacier’s life, in order to truly grasp its decline.
Sound deepens this effect. Led by Bjorn Victorsen and guided by glacier sound researcher Konstantin Vlasic, the team used specialized microphones to record the sonic life of ice. “You can’t really see glaciers move,” informed Doja. “We had to use sound to get the movement.” The result is a sensory experience that makes time audible.
A Bridge Between Memory and Landscape
While the film is grounded in emotion and ecology, its construction relies on a quiet layer of technological innovation. The team digitized fragile manuscripts, restored aging family footage, and used high‑resolution sensors to capture glacier surfaces that shift by millimeters. These tools allowed the filmmakers to place centuries of material in direct conversation.
The archival process became a form of preservation in its own right. By scanning and stabilizing footage from the 1930s, the team ensured that the visual memory of Iceland’s landscapes would endure beyond the film itself. The same is true for the manuscripts from 1200, which were photographed using controlled‑light imaging to reveal details invisible to the naked eye.
Technology also shaped the film’s rhythm. Slow‑motion capture, drone‑based mapping, and long‑interval time‑lapse sequences allowed the team to visualize temporal scales that humans rarely perceive. These tools made the glacier’s life legible allowing viewers to distinctly recognize its disappearance.
Sensing the More‑Than‑Human World
The film’s sound design is one of its most innovative elements. The team used contact microphones, hydrophones, and geophones to record vibrations inside the glacier. These sensors captured frequencies that fall outside human hearing, then translated them into audible textures. The result is a soundscape that reveals the glacier’s internal movements.
This approach mirrors emerging research in environmental sensing, where scientists use similar tools to monitor ice stability, water flow, and seismic shifts. By integrating these methods into the film, Doja’s team created a bridge between scientific data and cinematic experience. The glacier serves as a subject of the film while acting as a storyteller for the climate crisis.
These technologies also reinforce the film’s central idea: that nature holds memory. The sensors reveal patterns, pulses, and rhythms that echo across time. They allow audiences to hear a world that is usually silent, and in doing so, they expand the emotional and scientific vocabulary of climate storytelling.
Collaboration Adds Texture and Emotion
Collaboration shaped every stage of the project. Doja describes the process as playful, even when the themes were heavy. Andri’s humor and curiosity helped keep the work grounded. The team held story retreats in Iceland, near the site of the vanished Okjökull glacier, where they explored themes, textures, and emotional tones together.
The filmmaking process remained open and iterative as Doja shared narration drafts with Andri. He, in turn, shared writing with her. Editors and producers shaped the material in conversation with both. “It was a constant iterative process of working together,” Doja mentioned. That transparency ensured authenticity and protected the emotional integrity of the story.
The resulting material is a film that feels lived‑in. It carries the fingerprints of many people, treating their memories as a shared responsibility and their collaboration as a form of care. It takes the storytelling one step further, helping audiences collectively to imagine the future.
Time and Water stands out against climate narratives that can feel exhausted. Her approach takes a different path by blending science, history, and personal memory into a story that expands the imagination. It asks viewers to consider what remains, and their personal relationship with time. She leaves us with a conversation across generations and landscapes, inspiring us to repair rather that relationship.
