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.
