Microfibers in oceanic surface waters: A global characterization

open access: yesScience Advances, 2020
Contrary to global production, most fibers floating in the ocean are not synthetic but natural fibers of animal or plant origin. Microfibers are ubiquitous contaminants of emerging concern.

Potassium isotopic heterogeneity in subducting oceanic plates

open access: yesScience Advances, 2020
High-precision K isotopic measurements identify crustal inputs to the mantle and controls on oceanic K cycle. Oceanic crust and sediments are the primary K sinks for seawater, and they deliver considerable amounts of K to the mantle via subduction ...

The challenge of the oceanic feeling: Romain Rolland’s mystical critique of psychoanalysis and his call for a ‘new science of the mind’ [PDF]

open access: yes, 2017
In a letter written in 1927, the French writer Romain Rolland asked Sigmund Freud to analyse the “oceanic feeling,” a religious feeling of oneness with the entire universe.

Top-down estimate of a large source of atmospheric carbon monoxide associated with fuel combustion in Asia [PDF]

open access: yes, 2002
We simulate the oceanic and atmospheric distribution of methyl iodide (CH3I) with a global 3-D model driven by assimilated meteorological observations from the Goddard Earth Observing System of the NASA Data Assimilation Office and coupled to an oceanic ...

The oceanic sink for anthropogenic CO2 from 1994 to 2007

open access: yesScience, 2019
The state of ocean CO2 uptake The ocean is an important sink for anthropogenic CO2 and has absorbed roughly 30% of our emissions between the beginning of the industrial revolution and the mid-1990s. This effect is an important moderator of climate change,

Primary production of the biosphere: integrating terrestrial and oceanic components

open access: yesScience, 1998
Integrating conceptually similar models of the growth of marine and terrestrial primary producers yielded an estimated global net primary production (NPP) of 104.9 petagrams of carbon per year, with roughly equal contributions from land and oceans ...

Handbook of methods for the analysis of the various parameters of the carbon dioxide system in sea water. Version 2 [PDF]

open access: yes, 1994
The collection of extensive, reliable, oceanic carbon data is a key component of the Joint Global Ocean Flux Study (JGOFS). A portion of the US JGOFS oceanic carbon dioxide measurements will be made during the World Ocean Circulation Experiment ...

Glacial cycles drive variations in the production of oceanic crust [PDF]

open access: yesScience, 2014
Connecting orbit to the ocean floor The amount of magma erupted at mid-ocean ridges can be modified by periodic ice ages that alter sea level. Crowley et al.

Impact of El Niño Variability on Oceanic Phytoplankton

open access: yesFrontiers in Marine Science, 2017
Oceanic phytoplankton respond rapidly to a complex spectrum of climate-driven perturbations, confounding attempts to isolate the principal causes of observed changes.
