A diurnal, data-driven light installation for a clifftop promenade above the Juan de Fuca Strait. The representation and the thing represented share the same circular field.
Ocean Scribe is a diurnal light instrument. A 3.6-metre circle of live oceanographic data — wave period, tide state, dissolved oxygen, water temperature — rendered as colour, flow, and pulse. At its centre, a 250 mm porthole holds a fisheye view of the Juan de Fuca Strait: the thing the data describes.
The work is engineered as a permanent, site-responsive piece for a clifftop promenade above the Strait near Sooke, British Columbia. It is daylight-primary by design — the LED array is high-density and high-luminance, calibrated to read confidently in coastal noon sun. After civil twilight, the installation enters a proximity-activated, reduced-luminance mode calibrated to dark-sky and ecological spectrum guidelines.
When the animation rises, the ocean recedes behind the data. When it dims, the strait reads through. The boundary between these two conditions is programmable in software, and the work moves between them across the day.
The viewer face is a 3700 × 3700 mm welded Corten weathering steel frame, 900 mm deep — a cubic object, square in all elevations. Centred within it sits a single Ø3600 mm luminous disk — a unified, high-density RGBW LED array within a 130 mm Lambertian white light-mixing cavity, producing smooth continuous colour across the full circular face without visible pixel segmentation.
At the geometric centre, a conical matte-black optical tunnel narrows from Ø800 mm at the ocean-facing end to Ø250 mm at the viewer aperture, terminating in a wide-angle fisheye lens assembly. The platform raises the frame 900 mm above grade.
The tunnel is conical: Ø250 mm at the viewer-facing aperture, opening to Ø800 mm at the ocean-facing end where the wide-angle fisheye lens assembly is seated. At 715 mm depth it falls within the optimal working distance for direct-view fisheye optics, with full lens visibility maintained from all eye positions within the viewer aperture. The cone half-angle of 21.1° places the dark receding walls visibly in the viewer's peripheral field — a presence, not merely a tube.
The tunnel interior is finished in ultra-matte black (<1% reflectance) so that it reads as a clean dark circle when the lens is dim and as a precise pictorial frame when the strait is bright. Rain on the lens is treated as a meaningful condition of the work, not a defect.
Upper and lower LED zones are symmetric about the horizontal centreline.
Data active. The full Ø3600 mm disk renders live ocean data as colour, flow, and pulse. The animation is dominant; the centre porthole reads as a small dark or quietly lit circle.
Transparent. The LEDs dim toward black; the strait reads through the central fisheye lens. The disk recedes. The porthole becomes the picture.
The boundary between these two conditions is software-defined and continuously variable. Across the day, the work moves fluidly between a unified luminous surface, a dim ground with a bright porthole, and every gradient between. This is the core compositional logic of the piece.
From viewer side to interior: a 3–4 mm sacrificial clear polycarbonate sheet that takes the brunt of weather, salt, sand, and any incidental contact; a 10 mm Lexan MR10 polycarbonate panel with hard anti-graffiti and abrasion coating, the structural protection layer; a 5 mm precision-etched acrylic diffusion panel that produces the smooth Lambertian face of the disk.
Behind the diffuser sits the 130 mm Lambertian white light-mixing cavity, then the RGBW LED array, then an aluminium heatsink and the wiring zone. All three protective panels are field-replaceable without disassembling the light engine. The sacrificial sheet is consumable; the inner two panels are long-lived.
The installation is sited approximately 25 metres back from the cliff edge on an existing coastal promenade. The viewer face addresses the inland path; the ocean-facing aperture is set toward the Strait and is not accessible from the path.
The fisheye behind the central tunnel captures roughly a 180-degree panorama of the Strait and the Olympic Mountains beyond. Underground services for power and data are routed along the existing path corridor.
Final position is subject to CRD approval, geotechnical survey, and ecological assessment.
A small computer at the site reads live oceanographic streams and renders them as continuous animation across the disk. Every pixel is a function of the strait beyond the lens. Data sources and the specific mapping of each stream to luminous parameters will be determined through the development process.
Candidate parameters include wave height, swell period, wind, tide state, water temperature, dissolved oxygen, pH, and turbidity. Primary sources include Ocean Networks Canada and CIOOS Pacific. Final source selection and API integration will be confirmed during development.
Each data stream is mapped to a luminous parameter — colour, flow, pulse, density — through a calibrated mapping authored in TouchDesigner. Multiple aesthetic form translations of the data will be developed during production. These translations will be documented and made available as an interpretive guide for viewers who wish to understand what they are looking at.
Daylight-primary. Dawn through full daylight is the principal operating window. After civil twilight, proximity-activated reduced-luminance mode calibrated to dark-sky and ecological spectrum guidelines. The interpretive guide, data documentation, and project record will be maintained on the project website.

Earlier studies. The current resolved form — square Corten frame, unified circular disk, central porthole onto the strait — is the result of working through these alternatives.
These are working studies. The final design is the configuration documented in sheets 01 – 05 above.
