Pioneer Array Relocation

The Pioneer Array was initiated in 2016 as a re-locatable coastal array suitable for moderate wave and current regimes on the continental shelf and upper slope. The Pioneer Array is currently located off the coast of New England. It consists of cross-shelf moored arrays and autonomous vehicles that enable examination of upwelling, shelf break fronts, and cross-shelf exchanges.

After a two-phase Innovations Lab series between January and June of 2021, a new location was decided upon in the Southern Mid-Atlantic Bight. The Pioneer Array relocation is planned during 2024.


Timeline of Activities

Phase 1 Innovations Lab

  • April 30, 2021 – NSF announces that the next location of the OOI Coastal Pioneer Array is the Mid-Atlantic Bight (MAB).

Phase 2 Innovations Lab

  • May 3-31, 2021 – Applications to participate in the Pioneer Array Phase 2 Innovations Lab are open.
  • May 12, 2021 – The Pioneer Array Phase 2 Micro Lab is held.
  • June 21-25, 2021 – The Pioneer Array Phase 2 Innovations Lab is held to collect recommendations on how the Pioneer Array configuration can be optimized at its new location in the Mid Atlantic Bight.
