Endurance 18:
Bi-Annual Recovery
and Deploy Mission

Winter Expedition to Coastal Endurance Array

Equipment becomes fouled as marine life makes it home. Batteries run out. Wind and waves take their toll. That’s why every six months, the Coastal Endurance Array team heads offshore of Oregon and Washington. The Endurance Team left the harbor in Newport, Oregon on March 7 for its bi-annual mission to ensure the ocean observing equipment keeps collecting and sharing data. We will be sharing news about what’s happening aboard the R/V Sikuliaq as Oregon State University scientists and engineers recovers and deploys equipment at the Coastal Endurance Array for the 18th time. Check back regularly for updates.
