aDate sampling (month/day/year).
bSampling locations (longitudinal arrangement from east to west of Baffin Bay).
cMean values (± standard deviation), average sea-ice concentration in spring between the years 1988 and 2017 (n = 30).
dHighly branched isoprenoid-fingerprint or “H-Print” carbon source index (H-print > 50% is associated with pelagic carbon, and H-print < 50% is associated with SC).
eSC = sympagic carbon.
fOM = organic matter (percentage of sediment mass).
giOM = ice organic matter (percentage of OM content in sediment).
hStable isotope ratios of carbon (δ13C) and nitrogen (δ15N).
iChl a = chlorophyll a.
jSediment textual groups: slightly gravelly sandy mud (SGSM), sandy mud (SM), gravelly mud (GM), and mud (M).
kThe minimum and maximum values obtained are shown in bold.
