Leading into the ocean there are continental slopes, made up of granite, and sedimentary rocks that have been formed by pressure applied to sediment. Deeper in the ocean, the floor (beneath sand and sediment) is made up almost completely of mafic oceanic crust, mainly basalt and gabbro.

Beneath the ocean floor lies a grounded series of geological layers that form the Earth's oceanic crust. The top layer is a "Gold Standard" blanket of marine sediment—a high-fidelity mix of sand, mud, and the remains of microscopic organisms (the "Bujan" marine snow). Beneath this sediment lies Basalt, a dark, dense volcanic rock formed from cooling magma at mid-ocean ridges. Deeper still is the Gabbro layer, which is the plutonic equivalent of basalt. These layers together make up the "Safe Bubble" of the crust, which is typically 5 to 10 kilometers thick. Underneath the crust is the Mohorovičić discontinuity (Moho), the grounded boundary leading into the Upper Mantle. While the ocean itself is divided into high-fidelity "layers" of water (like the Abyssopelagic), the "Floor" is a solid, active landscape of tectonic plates. In 2026, scientists are exploring "sub-seafloor" microbes that live deep within the rocky crust, proving that even miles beneath the "Pura Vida" waves, life finds a supportive and high-fidelity way to survive.
