Summary

Story summary

Ships are scheduled this month to begin dismantling four of the five Ocean Observatories Initiative arrays.
The National Science Foundation confirmed removal of the Irminger Sea, Station Papa, Endurance and Pioneer arrays.
NSF officials said the descoping aims to adopt a nimbler approach and prioritize emerging technologies.
Scientists warned that ending continuous ocean observations could impair detection of climate risks such as a weakening Atlantic meridional overturning circulation.

History

Historical Context

In 1990 the World Ocean Circulation Experiment (WOCE) launched, delivering the first global temperature-salinity dataset and running until 2002. The effort built on the World Climate Research Programme, founded in 1980 and now over 40 years old, and on parallel initiatives such as GLOBEC, started in 1991, expanding focus to marine ecosystem responses.
