Sea Shepherd

At Poseidon Ascend, we believe that true exploration goes hand in hand with responsible stewardship of our oceans. That’s why we are proud to support Sea Shepherd, a global marine conservation organization dedicated to defending wildlife, preventing illegal fishing practices, and safeguarding marine ecosystems.

By choosing to embark on a Poseidon Ascend expedition, you’re not only treating yourself to an unforgettable underwater adventure—you’re also making a tangible impact on ocean preservation. A portion of every expedition fee is donated directly to Sea Shepherd, helping them patrol the seas, protect vulnerable species, and continue their critical advocacy work.

Through our partnership, we aim to raise awareness of the urgent need for marine conservation and empower our guests to become ambassadors for the ocean. Thank you for joining us in this mission and making a difference beneath the waves.
