Redfield ratios of remineralization determined by nutrient data analysis

TL;DR: A nonlinear inverse method is applied to nutrient data upon approximately 20 neutral surfaces in each of the South Atlantic, Indian, and Pacific basins, between 400 and 4000 m depth by accounting for the gradient in nutrients due to the mixing of [open quotes]preformed[close quotes] concentrations of the major water masses, the nutrient changes due to biological activity are examined, and the time-mean, basinwide Redfield ratios calculated.

Abstract: A nonlinear inverse method is applied to nutrient data upon approximately 20 neutral surfaces in each of the South Atlantic, Indian, and Pacific basins, between 400 and 4000 m depth By accounting for the gradients in nutrients due to the mixing of [open quotes]preformed[close quotes] concentrations of the major water masses, the nutrient changes due to biological activity are examined, and the time-mean, basin-wide Redfield ratios calculated It is found that the P/N/C[sub org]/[sup O][sub 2] ratios of nutrient regeneration between 400 and 4000 m (corrected for the effect of denitrification) are approximately constant with depth and basin, at a value of 1/16[+-]1/117[+-]14/170[+-]10 These ratios agree with those of fresh organic matter, suggesting that the flux of organic material to the deep ocean may be dominated by fast-sinking matter produced by sporadic, high-productivity events Sedimentary denitrification reduces the N/P utilization ratio to 12 [+-] 2 between 1000 and 3000 m In the Indian and Pacific basins the C[sub org]/C[sub inorg] regeneration ratio decreases from approximately 7 [+-] 13 at 400 m to 3 [+-] 1 at 1000 m and to 1 [+-] 05 at 4000 m, suggesting a significant amount of calcium carbonate dissolution above the calcite lysoclines in themore » Indian and Pacific oceans 74 refs, 8 figs, 3 tabs« less

TL;DR: In this paper, a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) is presented.
Biogeochemical controls and feedbacks on ocean primary production
TL;DR: Elucidating the biogeochemical controls and feedbacks on primary production is essential to understanding how oceanic biota responded to and affected natural climatic variability in the geological past, and will respond to anthropogenically influenced changes in coming decades.

TL;DR: The in situ CaCO3 dissolution rates for the global oceans from total alkalinity and chlorofluorocarbon data are estimated, and the future impacts of anthropogenic CO2 on Ca CO3 shell–forming species are discussed.

TL;DR: In this paper, the authors reveal two broad regimes of phytoplankton nutrient limitation in the modern upper ocean: Nitrogen availability tends to limit productivity throughout much of the surface low-latitude ocean, where the supply of nutrients from the subsurface is relatively slow.

The relative influences of nitrogen and phosphorus on oceanic primary production
TL;DR: In this article, the competition between nitrogenfixing and other phytoplankton is inserted into a two-box global model of the oceanic nitrogen and phosphorus cycles, with surface waters more deficient in nitrate than phosphate in the steady state.

VERTEX: carbon cycling in the northeast Pacific
TL;DR: In this paper, the vertical derivative of particulate fluxes may indicate solute regeneration rates, and accordingly regeneration rates for C, H and N were estimated under the assumption that 1.5, 1.0 and 0.25 moles of O 2 were used for each mole of N, C and H regenerated.

TL;DR: In this article, a general definition of the nonlinear least squares inverse problem is given, where the form of the theoretical relationship between data and unknowns may be general (in particular, nonlinear integrodierentia l equations).

TL;DR: In this paper, the authors proposed a method for the detection of biological oceanographic processes using biological oceanography processes, which they called Biological Oceanographic processes (BOP). But this method is not suitable for outdoor applications.
