The flux of iron from continental shelf sediments: A missing source for global budgets
- V. A. Elrod, W. Berelson, K. Coale, K. Johnson
- Environmental Science, Geology
- 1 June 2004
[1] The flux of dissolved iron from sediments to the water column was measured with flux chambers along the California coast over a five-year period. High fluxes were observed from sediments on the… Expand
Mesoscale Iron Enrichment Experiments 1993-2005: Synthesis and Future Directions
- P. Boyd, T. Jickells, +20 authors A. J. Watson
- Environmental Science, Geology
- Science
- 2 February 2007
Since the mid-1980s, our understanding of nutrient limitation of oceanic primary production has radically changed. Mesoscale iron addition experiments (FeAXs) have unequivocally shown that iron… Expand
Marine Chemistry Discussion Paper What controls dissolved iron concentrations in the world ocean
- K. Johnson, R. Gordon, K. Coale
- Geology, Chemistry
- 1 July 1997
Dissolved ( value in the data set at a depth near 750 m, where variability is at a maximum. The minimum concentrations are found at stations in the remote central Pacific and the maximum values occur… Expand
Testing the iron hypothesis in ecosystems of the equatorial Pacific Ocean
- J. Martin, K. Coale, +41 authors N. W. Tindale
- Biology
- Nature
- 8 September 1994
The idea that iron might limit phytoplankton growth in large regions of the ocean has been tested by enriching an area of 64 km2 in the open equatorial Pacific Ocean with iron. This resulted in a… Expand
Copper complexation in the Northeast Pacific
- K. Coale, K. W. Bruland
- Chemistry
- 1 September 1988
Copper titrations were conducted at sea with differential pulse anodic stripping voltammetry to examine the degree to which copper was associated with organic ligands. Greater than 99.7% of the total… Expand
Control of community growth and export production by upwelled iron in the equatorial Pacific Ocean
- K. Coale, S. Fitzwater, R. Gordon, K. Johnson, R. Barber
- Environmental Science
- Nature
- 1 February 1996
THE 'iron hypothesis'1,2 states that phytoplankton growth and biomass are limited by low concentrations of available iron in large regions of the world's oceans where other plant nutrients are… Expand
Trace metal concentrations in the Ross Sea and their relationship with nutrients and phytoplankton growth
- S. Fitzwater, K. Johnson, R. Gordon, K. Coale, W. Smith
- Geology
- 2000
Abstract Dissolved and particulate trace metal concentrations (dissolved Fe, Zn, Cd, Co, Cu and Ni; particulate Fe, Mn and Al) were measured along two transects in the Ross Sea during austral summer… Expand
Phytoplankton growth and biological response to iron and zinc addition in the Ross Sea and Antarctic Circumpolar Current along 170°W
- K. Coale, X. Wang, S. Tanner, K. Johnson
- Biology, Environmental Science
- 1 March 2003
Deckboard enrichment experiments were conducted during the US JGOFS Antarctic Environment Southern Ocean Process Study to determine the community response to added iron and zinc and their effect on… Expand
A switch from Si(OH)4 to NO-3 depletion in the glacial Southern Ocean
- M. Brzezinski, C. Pride, +7 authors K. Coale
- Geology
- 1 June 2002
[1] Phytoplankton in the Antarctic deplete silicic acid (Si(OH)4) to a far greater extent than they do nitrate (NO3−). This pattern can be reversed by the addition of iron which dramatically lowers… Expand
234Th:238U disequilibria within the California Current1: 234Th:238U disequilibria
- K. Coale, K. W. Bruland
- Geology, Biology
- 1985
Profiles of dissolved and particulate 234Th were determined at several stations within the California Current. Modeling of the disequilibria between the 234Th and 238U within the surface waters… Expand
