Temporal variability of particulate flux in the northern Bering Sea

Pelagic primary productivity and upper ocean nutrient dynamics across Subarctic and Arctic Seas

“…After ice correction, the highest level of new production was still found in the BE‐CH (average 396 mg C m −2 d −1 ; Table ), which agrees reasonably well with other estimates of export production of 253–654 mg C m −2 d −1 in the North Bering [ Fukuchi et al ., ] between June and September 1988 using sediment traps, and an average of 456 mg C m −2 d −1 on the Chukchi shelf [ Moran et al ., ]. Ice‐corrected new production was lower and very similar in the CAA and BB‐LS domains.…”

The benthos: the ocean’s last boundary?

“…Because the water temperature is between 0 and less than -1°C all year round, organic matter decomposes much more slowly than in tropical systems and maintains its nutritional potential for months (Gili et al 2001). A similar example is given by Fukuchi et al (1993) in the Bering Sea. These examples support the hypothesis made by Grebmeier and McRoy (1989), which proposes that benthic communities reflect processes occurring in the overlying water.…”

Carbon and nitrogen assimilation in the Bering Sea clams Nuculana radiata and Macoma moesta

“…The weight-based C:N ratio as a measure of food quality was 11.2 in the experimental food, which represents a mid-range quality food source between the high quality of a sinking marginal ice algal bloom occurring late in the spring and a more refractory, open-ocean particulate organic matter in the summer and fall (Falk-Petersen et al, 1998;Leu et al, 2010;Tremblay et al, 2006). Also, the POC:chl ratio of~65 is near the middle of established ranges of 15-180 for ice algae (Fukuchi et al, 1993;Juul-Pedersen et al, 2008;Leu et al, 2010).…”

“…Algal food quantity (based on chl) supplied to the experiments was scaled to natural concentrations during sea ice algal release occurring in the northern Bering Sea (Cooper et al, 2002;Dunton et al, 2005;Fukuchi et al, 1993;Olson and Strom, 2002). Unfortunately, the initial chlorophyll measurements of the experimental algal food were faulty, resulting in~8 times lower than intended food concentrations in jar experiments.…”
