The metabolism of the Arctic Ocean is marked by
extremely pronounced seasonality and spatial heterogeneity
associated with light conditions, ice cover, water masses and
nutrient availability. Here we report the marine planktonic
metabolic rates (net community production, gross primary
production and community respiration) along three different
seasons of the year, for a total of eight cruises along the
western sector of the European Arctic (Fram Strait – Svalbard
region) in the Arctic Ocean margin: one at the end of
2006 (fall/winter), two in 2007 (early spring and summer),
two in 2008 (early spring and summer), one in 2009 (late
spring–early summer), one in 2010 (spring) and one in 2011
(spring). The results show that the metabolism of the western
sector of the European Arctic varies throughout the year,
depending mostly on the stage of bloom and water temperature.
Here we report metabolic rates for the different periods,
including the spring bloom, summer and the dark period, increasing
considerably the empirical basis of metabolic rates
in the Arctic Ocean, and especially in the European Arctic
corridor. Additionally, a rough annual metabolic estimate for
this area of the Arctic Ocean was calculated, resulting in a
net community production of 108 g Cm−2 yr−1.
