attribute NC_GLOBAL acquisition_description String Sea ice brines were collected by the sackhole brine collection method.
Briefly, sea ice cores were drilled approximately three quarters of the way
through the ice column and removed to allow brine from the surrounding sea ice
to percolate for collection over several hours. Brines were collected and
pooled into 20 L acid-washed and sample rinsed cubitainers for transport to
the Barrow Arctic Research Center.


Cryopeg brines were collected from discrete boreholes drilled in the floor of
the CRREL Ice Mine (also known as the Barrow Permafrost Tunnel). Briefly,
permafrost boreholes were drilled with an ethanol-rinsed SIPRE corer, and
brines were collected from the boreholes with a sterile vacuum pump apparatus.
Detailed notes about cryopeg brine collection can be found in\u00a0Cooper et
al. 2019.


Biological abundance samples were fixed in the field immediately after each
sample collection with formaldehyde at a final concentration of 2%. All
samples were placed in insulated containers and transported to the Barrow
Arctic Research Center within a few hours of collection and stored at 4\u02daC
until aliquots were taken for each measurement. Nutrient and isotope aliquots
were frozen and stored at -20\u02daC for transport back to the University of
Washington and the University of Alaska Fairbanks. All analytical methods
except for isotope measurements are detailed in Cooper et al. 2019
