Antarctic Expedition to Find Endurance Shipwreck Made Surprising Seafloor Discovery | News Channel 3-12
Scientists discovered over 1,000 yellowfin notie fish nests in geometric patterns, highlighting a vulnerable marine ecosystem crucial for Antarctic biodiversity protection.
- ROV 'Lassie' aboard the South African polar research vessel SA Agulhas II recorded over 1,000 circular nests on the western Weddell Sea seafloor, researchers reported October 29 in Frontiers in Marine Science.
- The calving of iceberg A68 opened previously sealed seabed, allowing the team to explore new areas using autonomous underwater vehicles and the ROV 'Lassie' aboard SA Agulhas II.
- Researchers found each nest swept clean of detritus, with nests in five patterns and parent guarding behavior reflecting the "selfish herd" concept in yellowfin notie.
- The finding strengthens arguments to designate a Marine Protected Area, as the study provides evidence the site qualifies as a Vulnerable Marine Ecosystem and would protect penguins and seals.
- While searching for the Endurance, the Weddell Sea Expedition 2019 team recorded over 1,000 nests but pack ice thwarted locating Sir Ernest Shackleton’s ship; lessons aided Endurance22 and broader Weddell Sea biodiversity studies.

Antarctic robot ‘Lassie’ uncovers thousands of icefish nests beneath Antarctic ice
Beneath the ice of Antarctica’s Weddell Sea, scientists discovered a vast, organized city of fish nests revealed after the colossal A68 iceberg broke away. Using robotic explorers, they found over a thousand circular nests forming geometric patterns, each guarded by yellowfin noties. The expedition, initially aimed at studying the ice shelf and locating Shackleton’s Endurance, instead unveiled a thriving, structured ecosystem in one of the harsh…
