⚠ Educational Reference Only
This calculator is based on PADI Recreational Dive Planner principles using the DSAT single-compartment decompression model. It is intended for educational reference only. Always use a calibrated dive computer or your physical PADI RDP Table for actual dive planning. Values do not account for altitude, cold or strenuous conditions, Nitrox, or individual physiology. Never dive beyond your training or certification level. PADI recreational depth limit: 130 ft / 40 m.
Ocean Conservation
PADI Project AWARE
For over 30 years, PADI AWARE has united divers, scientists, and ocean advocates to protect marine life and ecosystems. Through citizen science, policy change, and community grants, it empowers a global network of divers to take on the greatest threats facing our ocean — from marine debris and habitat loss to species extinction and climate change.
🗑️ Dive Against Debris® ↗
Divers survey and remove debris from underwater environments and report data that informs marine researchers and policymakers worldwide. Ground-breaking citizen science in action.
🦈 Vulnerable Species Protection ↗
PADI AWARE has helped secure international protection for over 100 species of sharks and rays — animals critical to healthy ocean ecosystems and increasingly threatened by finning and bycatch.
📍 Adopt the Blue ↗
The world's largest network of underwater sites dedicated to conservation action. Dive centers and individual divers can adopt a local site and commit to ongoing monitoring and protection efforts.
🎓 AWARE Courses ↗
PADI instructors have educated millions of divers on how to protect the ocean. Courses include Dive Against Debris, Coral Reef Conservation, and the full AWARE Specialist rating.
Blueprint for Ocean Action
- → Remove ocean debris and combat plastic pollution
- → Expand marine protected areas and safeguard biodiversity
- → Protect endangered marine species
- → Restore degraded habitats and enhance ocean climate resilience
Patron of Mariners & Divers
Prayer of Saint Brendan the Navigator
Help me to journey beyond
the familiar and into the
unknown. Give me the faith
to leave old ways and break
fresh ground with You.
Christ of the mysteries,
I trust You to be stronger
than each storm within me.
I will trust in the darkness
and know that my times,
even now, are in Your hand.
Tune my spirit to the music
of heaven, and somehow, make
my obedience count for You.
Amen
“The sea and dry land belong to God, who made them, formed them by hand.”
— Psalm 95:5
