Carbon dioxide levels rising across wide swaths Arctic Ocean Canada Basin
2020/7/3
Melting of Arctic ice caused by climate change has exposed more sea surface to the atmosphere. Scientists have long suspected this trend would increase carbon dioxide in Arctic Ocean waters.Now U...
Scientists solve long-standing mystery:Why atmospheric carbon dioxide was lower during ice ages（图）
Scientists long-standing mystery atmospheric carbon dioxide lower during ice ages
2019/10/28
Since scientists first determined that atmospheric carbon dioxide was lower during ice ages than during warm phases, they have looked at why, theorizing that it may be a function of ocean circulation,...

Flying lab Southern Ocean appetite for carbon
2016/1/8
A team of scientists supported by the National Science Foundation (NSF) will launch a series of research flights over the remote Southern Ocean this month to better understand just how much ...
Radiocarbon in Corals: Records of the Carbon Cycle, Surface Circulation and Climate
Carbon Cycle Surface Circulation
2015/7/31
For more than two decades, coral skeletons have been used to reconstruct records of isotopic and chemical ratios in surface seawater (for reviews, see Druffel, 1997a; Gagan et al., 2000). Here I demon...
Inorganic carbon and biological oceanography above a shallow oxygen minimum in the entrance to the Gulf of California in the Mexican Pacific
oxygen minimum Inorganic carbon
2014/4/16
The eastern Pacific intermediate oxygen minimum layer (OML) is particularly well-developed and shoals close
to the Mexican coast. We obtained hydrographic profiles including oxygen concentration [O],...
Long-term patterns of dissolved organic carbon in lakes across eastern Canada: Evidence of a pronounced climate effect
Long-term patterns dissolved organic carbon lakes across eastern Canada a pronounced climate effect
2014/4/16
We analyzed the 21-yr dynamics of dissolved organic carbon (DOC) in 55 lakes during ice-free periods in five regions across eastern Canada in relation to total solar radiation (TSR),precipitation, air...
Black Carbon Transported from Asia Plays Role in Pacific Ocean Climate（图）
Black Carbon Oceanography
2007/3/19
March 15, 2007，More than three-quarters of the particulate pollution known as black carbon and transported at high altitudes over the West Coast during spring comes from Asia, according to a research ...
Colored dissolved organic matter and dissolved organic carbon exclusion from lake ice: Implications for irradiance transmission and carbon cycling
Colored dissolved organic matter dissolved organic carbon exclusion lake ice irradiance transmission carbon cycling
2014/5/26
Thick ice cover is a feature of cold-temperate, polar, and alpine lakes and rivers throughout much of the year. Our observations from Canadian lakes and rivers across the latitudinal gradient 46-80°N ...
Global net community production estimated from the annual cycle of surface water total dissolved inorganic carbon
Global net community annual cycle surface water total dissolved inorganic carbon
2014/6/9
Global net community production is determined, for the first time, from the decrease in salinity (S)-normalized total dissolved inorganic carbon (NCT = CT X 35/S) inventory in the surface mixed layer ...
Carbon dioxide partial pressure and 13C content of north temperate and boreal lakes at spring ice melt
Carbon dioxide partial pressure 13C content north temperate boreal lakes spring ice melt
2014/6/9
Carbon dioxide (CO2) accumulates under lake ice in winter and degasses to the atmosphere after ice melt. This large springtime CO2 pulse is not typically considered in surface-atmosphere flux estimate...
