Arctic Coring Expedition (ACEX) Recovers a Cenozoic History Arctic Ocean
2015/7/24
The Arctic Ocean is a small, nearly landlocked ocean basin that is the shallowest in the world (Figure 1). It has maintained a polar location since forming in Early Cretaceous times (Grantz et al., 19...
Hovercraft as a Mobile Science Platform Over Sea Ice in the Arctic Ocean
Arctic Ocean Science Platform Over Sea Ice
2015/7/17
Physical sampling of sea ice, the water mass, and subbottom geology in the Arctic Ocean is carried out from icebreakers or temporary ice camps deployed and supported by aircraft. Here, we consider an ...

Light nutrient control of photosynthesis
2014/4/2
During the 2010–2011 ‘Impacts of Climate Change on the EcoSystems and Chemistry of the Arctic Pacific
Environment’ project, we measured photosynthetic parameters in natural Arctic phytoplankton assem...
A substantial export flux of particulate organic carbon linked to sinking dead copepods during winter 2007–2008 in the Amundsen Gulf (southeastern Beaufort Sea, Arctic Ocean)
A substantial export flux particulate organic carbon linked sinking dead copepods during 2007–2008 the Amundsen Gulf (southeastern Beaufort Sea, Arctic Ocean)
2014/4/2
In the Arctic Ocean, vertical fluxes of particulate organic carbon (POC) remain low during the dark winter period because POC fluxes are derived from photosynthetic production. Passively sinking dead ...
Bromine measurements in ozone depleted air over the Arctic Ocean
Bromine measurements ozone depleted air the Arctic Ocean
2010/8/16
In situ measurements of ozone, photochemically active bromine compounds, and other trace gases over the Arctic Ocean in April 2008 are used to examine the chemistry and geographical extent of ozone de...
Quantifying the clear-sky temperature inversion frequency and strength over the Arctic Ocean during summer and winter seasons from AIRS profiles
the clear-sky temperature inversion frequency and strength the Arctic Ocean summer and winter seasons AIRS profiles
2010/8/13
Temperature inversions are one of the dominant features of the Arctic atmosphere and play a crucial role in various processes by controlling the transfer of mass and moisture fluxes through the lower ...
Circumpolar measurements of speciated mercury, ozone and carbon monoxide in the boundary layer of the Arctic Ocean
Circumpolar measurements speciated mercury ozone and carbon monoxide the boundary layer the Arctic Ocean
2010/8/13
Using the Swedish icebreaker Oden as a platform, continuous measurements of airborne mercury (gaseous elemental mercury (Hg0), divalent gaseous mercury species HgIIX2(g) (acronym RGM) and mercury atta...

Arctic Ocean marine carbon cycle evaluation air-sea CO2 exchanges ocean acidification impacts
2010/1/21
At present, although seasonal sea-ice cover mitigates atmosphere-ocean gas exchange, the Arctic Ocean takes up carbon dioxide (CO2) on the order of ?66 to ?199 Tg C year?1 (1012 g C), contributing 5–1...
