In 1896, Arrhenius provided the first roughly quantitative sense of the plausible magnitude of human-induced changes in the concentration of CO2 in the atmosphere. Since then, all chemists could be aw...
Volcanic ash as fertiliser for the surface ocean
Volcanic ash fertiliser the surface ocean
2010/8/12
Iron is a key limiting micro-nutrient for marine primary productivity. It can be supplied to the ocean by atmospheric dust deposition. Volcanic ash deposition into the ocean represents another externa...
A discrepancy between predictions of saturating nutrient uptake models and nitrogen-to-phosphorus stoichiometry in the surface ocean
saturating nutrient uptake models nitrogen-to-phosphorus stoichiometry the surface ocean
2014/4/17
We derive a simple prediction about euphotic zone N : P stoichiometry from a large class of models that use saturating nutrient uptake functions to characterize N and P acquisition by phytoplankton. T...
On the Determination of Kv in the Near-Surface Ocean from Acoustic Measurements of Bubbles
wind waves Acoustic Measurements Near-Surface Ocean

When wind waves break in deep water, clouds of small bubbles are produced which are diffused downwards by turbulence. We describe here how the vertical diffusion coefficient Kv of the turbulence near ...
Bubbles in the Near-Surface Ocean：Their Various Structures
Near-Surface Ocean Various Structures
2008/12/16
Air is entrained by breaking waves to produce bubbles. A highly transient macrobubble cloud is first generated under the breaker, with larger bubbles returning sooner to the sea surface. Those remaini...
Reconciling surface ocean productivity,export fluxes and sediment composition in a global biogeochemical ocean model

This study focuses on an improved representation of the biological soft tissue pump in the global three-dimensional biogeochemical ocean model PISCES. We compare three parameterizations of particle dy...
