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.
