| Summary: | This datasets represent an interdisciplinary sampling effort to better understand Arctic aquatic graminoid tundra. In particular, we assessed how environmental nutrient availability influences production of biomass and greenness in the 2 dominant aquatic tundra species: Arctophila fulva and Carex aquatilis.We sampled a total of 17 sites distributed across the Barrow Peninsula and Atqasuk, Alaska, following a nutrient gradient that ranged from sites with thermokarst slumping or urban runoff to sites with relatively low nutrient inputs. Additional information about methods, sites and other considerations on the dataset please refer to: Andresen CG, and Lougheed VL. Arctic aquatic graminoid tundra responses to nutrient availability.
