Interannual and Subdecadal Variability in the Nutrient Geochemistry of the Cariaco Basin
Interannual and Subdecadal Variability Nutrient Geochemistry Cariaco Basin
2015/7/17
The CARIACO Ocean Time Series program has made monthly measurements of oxygen, nutrients, and carbon system parameters (∑CO2, alkalinity, pH) in the Cariaco Basin since 1996. At the same time, sedimen...
Lava Geochemistry as a Probe into Crustal Formation at the East Pacific Rise
Lava Geochemistry Crustal Formation East Pacific Rise
2015/7/14
Basalt lavas comprise the greatest volume of volcanic rocks on Earth, and most of them erupt along the world's mid-ocean ridges (MORs). These MOR basalts (MORBs) are generally thought to be relatively...

low dissolved oxygen stracodes sediment geochemistry
2014/4/17
Low dissolved oxygen during the summer and early fall controls profundal continental ostracode distribution
in Crystal Lake (McHenry County), Illinois, favoring Cypria ophthalmica and Physocypria glo...
Ecological, landscape, and climatic regulation of sediment geochemistry in North American sockeye salmon nursery lakes: Insights for paleoecological salmon investigations
sediment geochemistry Ecological landscape climatic
2014/4/17
We used multiple linear regressions across a Northeast Pacific region 56-lake set to examine the influence of
sockeye salmon spawner densities and limnological, climatic, and watershed characteristic...
Sedimentary organic matter geochemistry of Clayoquot Sound, Vancouver Island, British Columbia
Sedimentary organic matter geochemistry Clayoquot Sound Vancouver Island British Columbia
2014/5/9
Surface sediment samples from three interconnected fjords of Clayoquot Sound, British Columbia, were density fractionated (1.6 g cm-3) to isolate discrete organic debris (OD) from mineral-associated o...
Controls of d13C-DIC in lakes: Geochemistry, lake metabolism, and morphometry
d13C-DIC in lakes Geochemistry lake metabolism morphometry
2014/5/19
We investigated δ13 carbon (C)-dissolved inorganic carbon (DIC) values in 72 lakes from diverse regions using literature data as well as new measurements for 32 lakes. δ13C-DIC varied broadly among la...
