TL;DR: Results from a series of Arctic Ocean transects are presented that show that the amount of CO2 in the surface waters has increased greatly recently, which will act as a barrier to future CO2 uptake and suggests that the Arctic Ocean will not become the large CO2 sink that some have predicted.

TL;DR: In this paper, the authors evaluate the biological and environmental factors that support communities of benthic prey on the continental shelves, with a focus on four macrofaunal biomass hotspots.

TL;DR: In this paper, the major environmental factors limiting the levels of primary production and possible future climate change on the ecosystems were examined, and it was shown that the bottom surface of the ice has a low specific uptake and productivity of phytoplankton, indicating that photosynthetic activity might be controlled by both light and nutrients.

TL;DR: For example, the Russian-American Long-term Census of the Arctic (RUSALCA) research cruise in 2004 covered all major water masses and contributed to a better understanding of the regional physics, nutrient dynamics, and biological systems.

TL;DR: In this paper, the authors investigated 32 net primary productivity (NPP) models by assessing skills to reproduce inte-grated NPP in the Arctic Ocean and found that most of the models were not able to fully reproduce the variability of in situ NPP, whereas some of them exhibited almost no bias.
