摘要

Boyd et al. (in press) propose a relatively simple tool that ob-servationalists can use to constrain the extent to which biological events, such as observed episodic phytoplankton blooms, are driven by dust supply to the ocean environment. In their paper, they use this tool to examine four case studies from the literature, one of which was authored by Lenes et al. (2001). Boyd et al. (in press) definitively conclude that the 100-fold Trichodesmium biomass increase on the West Florida shelf (WFS) that occurred by July 1999 could not be attributed to the alleviation of iron (Fe) limitation by deposition of Saharan dust. Their calculations of iron deposition incorporate multiple assumptions related to atmospheric dust concentration, solubility, wet deposition, and air column height. In all iron deposition studies, large uncertainties are associated with each of these variables.

7. The oceans mediate the response of global climate to natural and anthropogenic forcings. Yet for the past 2,000 years — a key interval for understanding the present and future climate response to these forcings — global sea surface temperature changes and the underlying driving mechanisms are poorly constrained. Here we present a global synthesis of sea surface temperatures for the Common Era (ce) derived from 57 individual marine reconstructions that meet strict quality control criteria. We observe a cooling trend from 1 to 1800 ce that is robust against explicit tests for potential biases in the reconstructions. Between 801 and 1800 ce, the surface cooling trend is qualitatively consistent with an independent synthesis of terrestrial temperature reconstructions, and with a sea surface temperature composite derived from an ensemble of climate model simulations using best estimates of past external radiative forcings. Climate simulations using single and cumulative forcings suggest that the ocean surface cooling trend from 801 to 1800 ce is not primarily a response to orbital forcing but arises from a high frequency of explosive volcanism. Our results show that repeated clusters of volcanic eruptions can induce a net negative radiative forcing that results in a centennial and global scale cooling trend via a decline in mixed-layer oceanic heat content.
