The Howe Island biocomplexity grid is located on a 1.5 x 0.5 km island off the delta of the Sagavanirktok River, west of the Endicott Causeway in the Prudhoe Bay oilfield, AK. There is one 10 x 10 m grid, with a complex of vegetation types created by 10 to 30-m polygonal cracking due to permafrost ice-wedges, smaller 1 to 3-m non-sorted circles, and small 10-20 cm surficial desiccation cracking. There is sparse vegetation on the sorted circles and more continuous vegetation between the sorted circles and in the troughs between the polygons.
