   Duration: 1998 - ongoing
   Dataset ID: 210288001

   Abstract:

Collections of airborne sand are obtained at the 15 NPP sites and the Geomet site. The collections are taken using BSNE collectors. The collectors are turned into the wind with wind vanes. The amount of material collected corresponds to the horizontal flux at the height of the collector and the opening area of the collector and the duration of the sampling time. The five heights of the BSNE collectors above the soil surface are 5, 10, 20, 50, and 100 centimeters for every location where samples are taken. The hypothesis of the experiment is that the vertical flux of the particles smaller than 10 micrometers is a constant ratio of the horizontal sand flux. The objectives of the experiment are to find patterns of sand flux rates as affected by soil and vegetation.


   Additional information:

15 NPP sites established in 1989 Geomet site located in JER Pasture 8B

   Methods:

Field data sheets, sediment samples.

   Methods:

BSNE collectors were emptied quarterly and the collected sample weighed. Detailed steps and guidelines used to collect and weigh the samples can be found in the "BSNE Dust Collector Procedure". Samples are archived.

   Maintenance:

quarterly (every 3 months)
