Phases
Gates, not dates.
The path
From programs to a place.
Phase 0: Planning and programs
Starts when
Now
- This website and its research
- Advisors from science, education and accessibility
- Talks, pop-up demonstrations of underwater robots (ROVs) and citizen-science days with existing local organizations, if they agree
Finished when
A fiscal sponsor or nonprofit in place, and at least one venue willing to host
Phase 1: Temporary exhibit (Format A)
Starts when
A host agreement, insurance and licensed content
- 1,000–3,000 sq ft exhibit for one or more seasons
- Visitor evaluation: who comes, what they learn, what they ask for
Finished when
Evidence of demand and audiences
Phase 2: Feasibility study
Starts when
An independent nonprofit board and Phase 1 results
- Market, site, cost and operating study by independent consultants
- Conversations with owners about land or buildings
Finished when
A board decision with a funding plan
Phase 3: Discovery center (Format B)
Starts when
Land or a building offered, and capital plus operating funding committed
- Design, permits and construction or adaptive reuse
- Opening only when governance, staff and funding are in place
Finished when
Opening
Phase 4: Aquarium decision (Format C)
Starts when
A board decision to study live animals, once the discovery center is open and stable
- A separate, independent study
Finished when
Go only if every hard gate on the Science & Conservation page is met; otherwise (the default) no-go
Detailed specifications for adapting a building, and its materials list, come only when there is a real building. Nothing is designed for construction yet. Once an owner agrees to a space, a licensed architect and engineers would write the drawings, specifications and materials list, with the owner's permission and the required reviews and permits. Materials would follow the plan's rules: reused, local and low-carbon first.
Costs
Benchmarks, not estimates.
Real figures from comparable projects, so nobody underestimates what each format means. None is an estimate for this project, and none is a request for money.

What this implies (our reading, not a sourced fact): the illustrative reference center on the Experiences page, about 14,300 sq ft gross, would likely need on the order of $1–2 million a year to run, with roughly half from public and private support rather than earned income such as admissions, programs and rentals, before free or low-cost access is added. Testing that is the main job of a feasibility study.

Governance
Who would be responsible.
- Start under a fiscal sponsor or form a Pennsylvania nonprofit.
- Register with the Pennsylvania Department of State before soliciting if anyone is paid to solicit. If all fundraising is done by unpaid volunteers or officers, register within 30 days after gross contributions exceed $25,000 in a fiscal year.
- An independent board with a science and education advisory council, an accessibility advisor, and community members from South Bethlehem.
- Aethon is the data and mapping partner, agreed on 19 October 2026. Aethon supplies the maps and data; the center does public education. Aethon does not fund, own, operate or approve the center. The same person founded Aethon and is planning the center, so a future board must manage that conflict of interest with a conflict-of-interest policy, an independent board majority, arm's-length written agreements and credit for any data or equipment.
- No construction fundraising, ticket sales or opening dates until governance, a site and permits are in place.

Major risks
What could go wrong, and what we would do.
No land or building is offered
LikelihoodHighImpactHighStart with hosted exhibits; prefer adaptive reuse; never assume donated land.
Owner, once an organization exists: Board
Operating deficits after opening
LikelihoodHighImpactHighFeasibility study first; multi-year operating commitments before construction; modest size.
Owner, once an organization exists: Board
Competing for the same audiences as Da Vinci and others
LikelihoodMediumImpactMediumCollaborate; specialize in ocean exploration and data; share programs rather than duplicate.
Owner, once an organization exists: Executive director
Brownfield, flood or karst conditions on a site
LikelihoodMediumImpactHighCovenant review, FEMA check and geotechnical study before any design.

Licensing or attribution mistakes

Overstated science or invented discoveries

Animal welfare failure (Format C)

Confusion with Aethon, the City or ArtsQuest
LikelihoodMediumImpactMediumStatus labels on every page. The Aethon partnership is recorded with its date, its limits and the founder's conflict of interest; a conflict-of-interest policy, an independent board majority and arm's-length written agreements would manage it.
