In piston cores from the open subarctic Pacific and the Okhotsk Sea, diatom-bound δ15N
(δ15Ndb), biogenic opal, calcium carbonate, and barium were measured from coretop to the …

One of the most important breakthroughs in oceanography in the last 30 years was the
discovery that iron (Fe) controls biological production as a micronutrient, and our …

Using multiple lines of evidence, we demonstrate that volcanic ash deposition in August
2008 initiated one of the largest phytoplankton blooms observed in the subarctic North …

Projected responses of ocean net primary productivity to climate change are highly
uncertain. Models suggest that the climate sensitivity of phytoplankton nutrient limitation in …

The flux of biologically produced organic matter from the surface ocean (the biological
pump), over an annual cycle, is equal to the annual net community production (ANCP) …

Iron is an essential nutrient and plays an important role in the control of phytoplankton
growth (Martin et al., 1989). Atmospheric dust has been thought to be the most important …

Phytoplankton community composition profoundly affects patterns of nutrient cycling and the
dynamics of marine food webs; therefore predicting present and future phytoplankton …

The distribution of silicon in the North Pacific is controlled by the utilization of silicic acid by
diatoms, a process that fractionates silicon (Si) isotopic compositions. Silicon isotope …

The spring zooplankton community in the Strait of Georgia (British Columbia, Canada) is
characterized by the presence of several calanoid copepod species which collectively make …

In comparison to the open ocean, several additional processes including coastal upwelling,
river discharge, tidal mixing, estuarine circulation and benthic remineralization enhance …
