Zusammenfassung |
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 C m−2 yr−1. |
