Scientists discover giant kelp forest at 50 meters depth off Galapagos
This digest was compiled by AI from multiple sources — links to the originals are below.
Researchers discovered a dense kelp forest at depths of 50 to 70 meters on seamounts near the Galapagos Islands. The forest is formed by the endemic species Eisenia galapagensis, previously known only from shallow waters. The discovery was made using a remotely operated underwater vehicle.
Key Facts
- The kelp forest extends between 50 and 70 meters depth on Galapagos seamounts.
- The forest is formed by Eisenia galapagensis, a species endemic to the Galapagos first recorded in 1934.
- The kelp specimens found are nearly twice as large as previously known Eisenia galapagensis samples.
- Researchers initially suspected a new species before the Charles Darwin Foundation confirmed the identity.
Discovery Details
Researchers were examining Galapagos seamounts with a remotely operated underwater vehicle when they encountered dense kelp at approximately 50 meters depth. Further investigation showed the forest extends from 50 to 70 meters below the surface. Kelp forests typically occur in cold and temperate waters, making this tropical occurrence unusual. Cold, nutrient-rich currents in parts of the Galapagos likely enable the kelp to thrive despite the tropical setting.
Species Identification
Scientists were studying Eisenia galapagensis, an endemic Galapagos species first recorded in 1934. The deep-water kelp appeared nearly twice as large and visually distinct from known Eisenia galapagensis specimens. This led researchers to consider the possibility of a new species. The Charles Darwin Foundation later confirmed the kelp is a form of Eisenia galapagensis, clarifying the identity of the long-mysterious algae.
