archipelagosAsteria

Asteria is an underwater formation composed of sedimentary and metamorphic rocks. It is located on the seafloor, often in conjunction with an oceanic crust. The structure of Asteria is the result of geological processes that have occurred over thousands or millions of years. This may include erosion of the rock face by the water pressure, weathered remains of islands that sank over time, or secondary structures such as pinnacles that on occasion come above the surface.

Archipelagos consisting of Asteria formations can be found throughout the world's oceans. Within these formations, a peculiar ecosystem often establishes. The living species of this environment often have a symbiotic relationship with the formations. The extremities of such an ecosystem can be linked with pollution presence in a given area, despite the Asteria remaining unaffected.

Asteria often remain isolated and evolve independently from their surface land counterparts over long periods of time. In effect, undersea archipelagos composed of these formations have more microorganisms and potential evolutionary pathways hidden within the complex structure compared to regular island formations.

An example of an Asteria archipelago can be found on the floor of the Pacific Ocean. Its structures, though partially eroded, continue to enhance an ecosystem. The uniqueness of the microorganisms inhabiting Asteria and other underwater formations creates tension between marine conservation and the area of scientific research.
