About the Mission

Protecting Living History
Beneath the Pacific

Eye on FSM is a community-driven monitoring program enabling divers, vessel crews, tour operators and members of the public to contribute to the long-term protection of the Federated States of Micronesia's extraordinary WW2 marine heritage and the ecosystems that have grown around these silent vessels over 80 years.

Truk Lagoon alone contains over 60 wrecks from Operation Hailstone (February 1944) — now home to coral gardens, sharks, turtles and an unparalleled diversity of marine life. These sites are irreplaceable. Your reports directly inform management decisions.

Oil Risk Monitoring
Many wrecks still contain fuel oil. We track signs of leakage before spills escalate.
🪸
Ecosystem Health
Documenting coral cover, fish populations and invasive species across all wreck sites.
🤿
Diver Reporting
Every dive is an observation opportunity. Report directly from the water or surface.
Heritage Protection
Safeguarding the structural integrity of wrecks as both memorials and marine habitats.
Why It Matters

The wrecks of Chuuk Lagoon — from aircraft carriers to oil tankers — still hold an estimated millions of litres of bunker fuel. Climate change, structural degradation and increasing vessel traffic create compounding risks to both the marine environment and local communities.

Traditional Owner Connection — The peoples of Chuuk, Pohnpei, Yap and Kosrae have maintained relationships with these waters for thousands of years. Eye on FSM works alongside Traditional Leaders and community groups in all monitoring activities.

Incident

Submit your observation securely. Reports can be submitted anonymously. Photos and videos strongly encouraged.

⚠ Witness Safety First
If you witness a suspected breach of law, do not approach any suspected persons. Record details safely from a distance and report immediately.
📍 GPS Tips for Divers
Record GPS coordinates at the surface before or after your dive. Note the wreck name and any visible landmarks. Depth and compass bearing from a fixed point also help.

Frequently Asked Questions

How it
Works

Everything you need to know about participating in Eye on FSM monitoring and protection.

You should report any environmental incident or suspicious activity you observe in FSM's marine waters — especially around known WW2 wreck sites. This includes oil sheens or fuel leaks, coral or reef damage, vessel grounding, ghost nets, marine animal injury or entanglement, unusual water discolouration, structural changes to wrecks, illegal fishing, and the removal of artifacts from wrecks. If in doubt, report it — no observation is too minor.

Yes. You have the full option of not identifying yourself or using a pseudonym when reporting suspected offences. Personal information you choose to provide is handled in accordance with FSM privacy regulations. Select the 'remain anonymous' option in the report form and no contact details are required.

For an active or spreading oil spill, call our 24-hour emergency line immediately: +691 3XX XXXX. Do not attempt to enter the water near the spill. Photograph or video the extent of the sheen from a safe distance, noting the time, GPS location, wind direction and approximate size of the affected area. Submit your report and photos via this form or email Report@eofsm.com as soon as possible.

You cannot record GPS at depth as signals don't penetrate water. The best approach is to record your GPS position at the surface immediately before descending at the dive site, and note the name of the wreck you're diving. Upon surfacing, note your GPS position again. If you use a dive computer with GPS integration, save your dive track. For incidents deep inside a wreck, note your position relative to a known reference point such as the bow, stern, mast or wheelhouse, along with the compass bearing and estimated distance.

Absolutely — and we strongly encourage it. Eye on FSM is designed for anyone who visits or works in FSM's waters, from first-time tourists to professional marine biologists and commercial vessel operators. You don't need any formal training or certification to submit a report. Your first-hand observations are invaluable. Even a simple photo of an unusual water colour or floating debris is a meaningful contribution.

Reports are reviewed by our field team, typically within 24–48 hours. Urgent incidents (oil spills, vessel groundings, structural collapses) are escalated immediately to our Chuuk field coordinator. Your report may be shared with FSM state environmental agencies, the Division of Marine Resources, or international partner organisations where appropriate. If you provided contact details, we will follow up to confirm receipt and may ask for additional information. All data contributes to our long-term environmental monitoring database.

The Eye on FSM app (currently in beta) is available for iOS and Android and provides: wreck location maps for offline use, guided reporting forms with GPS auto-fill, the ability to record and submit photos and video directly from your device, instant access to safe diving zones, and real-time alerts about known incidents near your location. The app is also compatible with Apple Watch and Wear OS smartwatches, allowing simplified in-water logging before a full report is completed on the surface.

Yes. The wrecks in FSM waters are protected under FSM federal and state law, and many are considered war graves under international maritime law. It is illegal to remove, disturb or damage any artifact, part of a wreck, or human remains. Diving is permitted at most sites under permit conditions, which vary by state. Chuuk State has designated Truk Lagoon as a State Historic Preservation site. Violations can result in significant fines and criminal prosecution.

Dive operators, liveaboard vessels, tour agencies and individual volunteers can register as official Eye on FSM monitoring partners. Partners receive training materials, access to the full monitoring platform, and are listed in our partner directory. Contact us at Report@eofsm.com with the subject line 'Monitoring Partner' to enquire. We particularly welcome applications from Chuuk-based operators, Traditional Owner groups, and community organisations.

The wrecks considered highest priority for oil risk monitoring are the Shinkoku Maru (largest oil tanker, Chuuk), the Rio de Janeiro Maru (submarine tender with significant fuel reserves, Chuuk), and the Hoyo Maru (tanker, Chuuk). These sites are subject to enhanced monitoring. All observations near these wrecks — including any sheen, unusual bubbling, discolouration or strong fuel odour — should be reported immediately.
