| Summary: | the east side. Polygon troughs have deepened and widened from thermokarst since the spill and cleanup occurred. The light-colored box just beyond the spill is a data recorder for measuring soil and air temperatures at this location. Notice the vegetation has not become green by this date. The green surface next to the road is moss growing in the unseeded strip. Seeding strips are left to right in this image. Fertilizer strips are arranged perpendicular to the seed applications and extend foreground to background. The light colored grass within the spill area is Puccinellia borealis, northern alkaligrass, which was included in experimental seeding on the site. Even though much of the spill site appears barren in this image, by the end of the growing season, it was relatively well covered with vascular plants. The most prominent seeded grass was the Umiat collection of northern alkaligrass. The seed source developed from a collection at ERA Helicopters, Deadhorse, was slower to develop than the Umiat collection, but the ERA source produced an acceptable stand of plants, whose heights were shorter than those of the Umiat seed source. The poorest seeded grass was Puccinellia augustata, which was hand collected in WOA and coated with phosphorus fertilizer, clay and talc to facilitate handling and |
