Shotgun metagenomes of wet tundra soils across the Arctic Coastal Plain, Alaska April 2018
This dataset includes 64 shotgun metagenomes (Illumina PE150) generated from three depths (5-10 centimeters (cm), 10-25 cm, and 30-35cm, when available) of three replicate soil cores from eight locations in the Arctic Coastal Plain, ranging from coastal sites near Utqiagvik to inland sites at Ivotuk...
