The dual isotopes of deep nitrate as a constraint on the cycle and budget of oceanic fixed nitrogen
- D. Sigman, P. J. DiFiore, +6 authors S. Pantoja
- Environmental Science
- 1 September 2009
We compare the output of an 18-box geochemical model of the ocean with measurements to investigate the controls on both the mean values and variation of nitrate d 15 N and d 18 O in the ocean… Expand
Air‐sea CO2 fluxes along the coast of Chile: From CO2 outgassing in central northern upwelling waters to CO2 uptake in southern Patagonian fjords

The role of fungi in processing marine organic matter in the upwelling ecosystem off Chile
- M. Gutiérrez, S. Pantoja, E. Tejos, R. Quiñones
- Biology
- 2011
In a study that spanned from March 2007 through November 2009, we report high fungal biomass and over 90% of extracellular enzymatic activity occurring in the size classes dominated by fungi during… Expand
Oceanography of the Chilean Patagonia

- Biology
- 23 March 1995
The effect of the chemical composition of seston on the egg-production rates (E,: eggs female-' d') of the copepods Acartia hudsonica Pinhey and Ternora longicornis (Muller) was studied in Long… Expand
Geochemistry of surface sediments from the fjords of Northern Chilean Patagonia (44–47°S): Spatial variability and implications for paleoclimate reconstructions
- S. Bertrand, S. Bertrand, K. Hughen, J. Sepúlveda, S. Pantoja
