NOAA Recovers Deep-Sea Orb, Finds Anemone Base

Summary

NOAA Maps Alaska

NOAA announced that a 4-inch orb recovered miles deep in the Gulf of Alaska is dead cells forming a sea anemone base.
The orb was retrieved by an operated vehicle from the NOAA Ship Okeanos Explorer during the Seascape Alaska program launched in 2021.
NOAA reports that 61% of U.S. waters off Alaska remain unmapped, a gap the Seascape Alaska effort seeks to close for mapping and territorial-claim work.

Summary

Scientists Identify Cuticle

Scientists found the golden orb’s outer layer is a chitin-rich cuticle that hosts deep-sea bacteria fueling the nitrogen cycle.
Whole-genome sequencing removed contaminant DNA and confirmed the cuticle’s composition matches the polymer of insect exoskeletons and fungal walls.
Researchers suggest the orb is either a shed cuticle left as the anemone moves or an incomplete pedal-laceration, creating a debris-based microbial hotspot that can sustain communities for months.
