Major ion and nutrient concentrations of water-soluble salts leached from aeolian material, McMurdo Dry Valleys, Antarctica (2013-2016)

Summary

Abstract: 

To evaluate the role of Antarctic aeolian transport in surface chemistry homogenization, fifty-three samples of aeolian material from the McMurdo Dry Valleys region of Antarctica were collected and analyzed for water-soluble major ions and nutrients at a 1:5 sediment:water ratio. Samples were collected seasonally from Alatna Valley, Victoria Valley, Miers Valley, and Taylor Valley (Taylor Glacier, East Lake Bonney, F6 (Lake Fryxell), and Explorer’s Cove) at five heights (~5, 10, 20, 50, 100 cm) above the surface between 2013 and 2015. This data package is associated with Aeolian Material Transport and Its Role in Landscape Connectivity in the McMurdo Dry Valleys, Antarctica, published by Diaz et al. in 2018 (DOI: 10.1029/2017JF004589).

sample_height_rel
  • Label: Relative sample height
  • Definition: Height above the ground where sample was collected. Relative terms (bottom lower, bottom middle, bottom upper, middle, top) loosely correspond with ~ 5, 10, 20, 50, 100 cm above the surface.
  • Type: Nominal
  • Missing values: None specified
sample_height_cm
  • Label: Sample height
  • Definition: Approximate sample height. The aeolian material collection trays were initially set to standardized heights above the surface (5, 10, 20, 50, and 100 cm). However, strong winds generated variation in heights among the individual units. Relative terms (bottom lower, bottom middle, bottom upper, middle, top) loosely correspond with ~ 5, 10, 20, 50, 100 cm above the surface.
