For families drawn to the ocean, sea water burials offer a meaningful, peaceful, and environmentally conscious way to say goodbye. The sea represents continuity, renewal, and the vast cycle of life. Whether through biodegradable urns, salt urns, eternal reefs, or scattering cremains, water-based memorials provide a respectful alternative to traditional cemetery burial.
Across the United States, more families are choosing ocean memorial options that minimize environmental impact while honoring personal wishes.
Sea-Water Burials and Biodegradable Urns
When planning sea-water burials, selecting the right urn is essential. Water biodegradable urns are specifically designed for the placement of cremation ashes before a water ceremony. These urns typically float briefly, allowing families time for a final goodbye, before sinking gracefully beneath the surface.
Some biodegradable urns break down naturally in as little as four hours, depending on water conditions. This ensures minimal environmental impact while maintaining dignity and ceremony.
Salt Urns
Salt urns dissolve easily when placed in water and are crafted entirely from natural materials. Many are individually hand-crafted from Himalayan Rock Salt, some deposits dating back 250 million years. Once submerged, the urn gradually dissolves, returning ashes gently to the sea.
Salt urns are:
-
Fully biodegradable
-
Free from harmful chemicals
-
Designed specifically for marine environments
-
Symbolic of returning naturally to the earth and water
Eternal Reefs: A Living Ocean Legacy
One of the newest and most eco-friendly memorial innovations connected to sea-water burials is the Eternal Reef concept.
Eternal Reefs are environmentally friendly memorial structures created by mixing cremated remains with marine-grade concrete to form artificial reef formations. These structures are then placed on the ocean floor, where they contribute to the marine ecosystem.
Benefits of Eternal Reefs include:
-
Supporting coral growth
-
Providing habitat for marine life
-
Contributing to ocean restoration
-
Creating a permanent living memorial
Rather than passing down an urn or occupying cemetery space, an Eternal Reef becomes a lasting environmental contribution. Families who value sustainability often choose this option as a way to continue giving back to the planet even after life.
Eternal Reefs is a leading organization in developing these living legacies, helping restore ailing marine ecosystems while honoring loved ones.
Scattering Cremains at Sea
Another common option is scattering cremains directly into the ocean.
Scattering cremains involves releasing ashes into the environment from an urn or scattering device. This practice is widely accepted in many religions and cultures. However, some Christian denominations may have restrictions, so families should consult spiritual advisors if needed.
Water scattering leaves minimal environmental impact when conducted responsibly. Cremated remains are sterile and natural in composition, making ocean scattering an environmentally safe option when local regulations are followed.
Midway through planning services, families considering sea-water burials often find that scattering ceremonies offer simplicity and emotional closure without permanent physical markers.
Legal Requirements in the United States
It is important to follow federal regulations for ocean burials.
In the U.S.:
-
Scattering must occur at least three nautical miles from shore
-
The EPA must be notified within 30 days
-
Only biodegradable materials may be used
-
Plastic, metal, or non-degradable containers are prohibited
Working with licensed burial-at-sea providers ensures full compliance with maritime and environmental laws.
Emotional and Symbolic Meaning
Ocean memorials symbolize:
-
Freedom
-
Eternity
-
Peace
-
Connection to nature
Families may include:
-
Flower petal releases
-
Reading of personal tributes
-
Military honors (when applicable)
-
Sunset ceremonies
The gentle return of ashes to the sea often provides a sense of calm and spiritual release.
Environmental Perspective
Compared to traditional burial:
Sea burial avoids:
-
Concrete vaults
-
Land use
-
Cemetery maintenance
-
Long-term ground disturbance
When biodegradable urns or Eternal Reefs are used, the environmental footprint remains minimal while potentially contributing positively to marine ecosystems.
