Nodular Fathoming explores entangled ways of knowing, sensing, and storytelling in the deep sea.
Rooted in collaborative research and poetic worldbuilding, the project moves across visual, sonic, and speculative practices to engage with the opacity, fragmentation, and unknowability of abyssal environments. Focusing on polymetallic nodules and the Clarion–Clipperton Zone as central figures, the project questions extractive narratives and linear epistemologies by assembling a plural vocabulary of response. Rather than explaining the deep ocean, Nodular Fathoming seeks to fathom it: to dwell in partiality, scale-shift, and submerged relations beyond representation.
Situated in plurality and opacity through embracing the unknownable, Nodular Fathoming (NF) is a worldbuilding process to both engage the opaque realities and deep uncertainties of the future of our ocean planet and refuse the homogenous (heroic, extractive, and inhumane) narratives that claim to know better and more thoroughly; yet, fuel endings of worlds. It proposes understanding our water world on its own terms by contemplating alongside its most mysterious, abundant, and essential environment, the ocean. By embracing the ocean's inherent fragmented, plural, thick, and trans-scalar coexistence, NF becomes a speculative storytelling device to fabulate within the unknowns of abyss(m)al times.
How has knowing the ocean been historically approached by science, industry and government?
Human exploration has attempted and continually strives to know the ocean with certainty through scientific knowledge production, which necessitates acts of exploration, mapping, collection, classification, quantification, mapping, modelling, and simulating. Objects of study are extracted, disembodied, and vivisected, displaced from their original environments with the hope of knowing them more fully. As measurements and models simulate and imitate worlds, cuts made to study and replicate one aspect of a phenomenon bifurcate and rift, creating knowns and their shadow traces, the unknowns. Scientific tools are limited in their ability to mediate realities of shifting, erupting, ooze-covered ocean floors, where sunlight cannot reach, attempts to know fully fall short and these shadow traces endure. Targets to map the entire seabed by 2030 and digital ocean twins further abstract wet worlds with conventions of land-based technology. The knowledge produced by such mapping endeavors facilitate the increasing parceling, exploitation, and commodification of the ocean through human agency, as the ocean is divided into grids and worlds.
Why is telling other and plural stories critical for the future of the ocean?
To hold space for the unknowable and embrace the innate resistance of somethings to being fully known, goes against the dominant paradigm of Science, which strives to resolve unknowns and uncertainty through continuous, ‘objective’ knowledge production. Saturated with deep uncertainties, contemporary climate and environmental issues connected to the ocean remain trans-scalar, tangled, and only partly visible. Global ecological, social, economic, and political decision-making is interlinked intimately with ocean futures. Yet, geologic timescales of impact and immense complexity of the interwoven global crises lay outside of human comprehension. Plans fall short and fail to acknowledge present realities with humility. Challenges surround communication in articulating the gravity of concerns, connecting emotionally, and mobilizing action. This suggests a different approach to storytelling is needed.
Why polymetallic nodules?
The human discovery and categorization of polymetallic nodules has been credited to the 19th century HMS Challenger expedition, recorded in the exploration Report on the Deep-Sea Deposits (1891). The masses are part of a new horizon for extractive fantasies and oceanic ‘land’ claims, which began in the 1970s. As the targets of prospectors, they are objectified as ‘critical’ minerals – singular and essential resources to serve humanity in the green energy transition for sustained urban futures. Immense energy and environmental damage would be expended for extraction of the nodules from their abyssal environments and for extractive metallurgy to separate complex geochemical assemblies into commodified elements (nickel sulfate, cobalt sulfate, copper, manganese). Nevertheless, the future is already being claimed and rendered as “metallic” by mining companies and design consultants, as oil drill ships are converted into polymetallic nodule collection vessels. While replacement nodules, underwater cables, pipelines, and violent fishing practices troll the ocean floor, companies invest in the further development of technologies to exploit deep sea environments. Science still has not reached a deep understanding how nodules relate to life and planetary systems. Findings that complicate and slow the efficiency of master plans are refuted with crafted rebuttals--both claiming scientific truths. Private enterprises make moves to operate outside of the International Seabed Authority (ISA) and UNCLOS (who although holding immense importance for global solidarity, have little ability to enforce when diplomacy fails). In spite of these attempts, the nodules themselves and the environment they inhabit resist being essentialized and fully knowable. They remain complex, multiple and entangled--the irreducible other.
Extended framework for NF
NF holds space for diverging partial perspectives through the assemblage of nodule worlds rooted in rhizomatic relations, a right to opacity, kin-making, and poetic engagement (in its broadest sense—myth, narrative, language itself). The slow and fragmented worldbuilding at the base of the ocean holds an idea of plural, non-linear storytelling that recognizes the inability of humans to ever know the ocean as a whole. Instead of seeking to know, they seek to fabulate: to embrace the other, complexity, uncertainties, multiplicities, alliances, and interconnectivities to foster improvisations, resilience, and collective, co-created futures that work with the unknowable. For example, the deep sea and its nodules hold an agency to refuse extraction by remaining unknown. To accept the mystery, opacity, and agency of those that resist being known or fully understood is to move beyond singular notions progress, through scientific knowledge accumulation for evidencing desirable futures (more often than not human-centered ones) and their accompanying homogenous, often extractive and inhumane, narratives.
“One of the paradoxes of ocean governance is that the body meant to protect the seabed from harm is also the one authorising its exploitation. The International Seabed Authority operates less as a neutral regulator than as a self-legitimising structure — writing legal frameworks that accommodate extraction while postponing the question of irreversible damage.”

Mixed Up Worlds for Abysmal Times
by Monica Hutton
Worlds are planned to be smelted before they are known as the ocean is divided into abstract grids to classify, record, and weigh it. This speculative storytelling device proposes holding space for political and ecological imaginations to coexist, refusing homogenous extractive narratives that move towards the abyss. Contradictions and mixed motivations for ocean futures are unsettling realities that can be fabulated with, as many futures exist at once.
Each deep sea nodule is a cosmic world mixed around a fragment. Over millions of years, layers of iron, manganese and other metals congeal around a piece of a shell, bone, plant, fossil.1 Although their discovery by humans has been credited to the 19th century HMS Challenger expedition, science has not reached a deep understanding of how nodules relate to life. Recorded in the exploration Report on the Deep-Sea Deposits2 (1891), nodule worlds were crushed and found to hold ‘cosmic dust’ that fell to Earth as cosmic spherules from meteorites. These microcosms spread across the seafloor as a constellation of ancient stories that connect far beyond their physical bodies, with non-human nuclei. Complex microbial communities on each extraplanetary geography pulled from the seabed are watched through microscopes.
Inaudible Harm, Epistemologies of Evasion and the Metrics of Deep Unknowing
by Burak Korkmaz Schwichow
Roughly 20% of the global seafloor has been mapped with high-resolution bathymetry¹, and even less has been biologically or chemically analysed. In the Clarion–Clipperton Zone alone, over 5,000 new species² are estimated to exist — the vast majority of which remain undescribed, unclassified, or poorly understood. Comprehensive environmental baselines are absent across most of the deep sea, with knowledge gaps encompassing not only biological taxa, but also sediment structures, ecological interactions, and geochemical processes.
We have long crossed the threshold. Past the stage of simply pointing to data voids, beyond the cartographer’s apology of “information not available.” We now stare into the deeper fracture — the unknowable unknowables. It is not a question of access, nor a lack of data infrastructure. It is the unutterability of what resists not only measurement, but even classification. What if the seabed hosts harms so thickly entangled with temporal and biological scales that they cannot be assimilated into a legend, a registry, a scientific appendix? What if they are not only not-yet-known, but never-to-be-known?
