Journal ArticleDOI
Paleoproductivity from benthic foraminifera abundance: Glacial to postglacial change in the west-equatorial Pacific
TL;DR: In this paper, the authors found that surface productivity is correlated with the rate of accumulation of benthic foraminifera on the deep-sea floor and that productivity during the last glacial maximum exceeded present productivity by a factor of between 1.5 and 2.0, with intermediate values for the midtransition period.

TL;DR: Observations implying that Atlantic meridional overturning circulation during the Last Glacial Maximum was neither extremely sluggish nor an enhanced version of present-day circulation are reviewed.
Journal ArticleDOI
Collapse of the California Current During Glacial Maxima Linked to Climate Change on Land

TL;DR: Both the timing and magnitude of the SST estimates suggest that the Devils Hole (Nevada) calcite record represents regional but not global paleotemperatures, and hence does not pose a fundamental challenge to the orbital (“Milankovitch”) theory of the Ice Ages.
Journal ArticleDOI
Deep-sea benthic foraminifera and biogenic opal: Glacial to postglacial productivity changes in the western equatorial Pacific
TL;DR: The accumulation rate of benthic foraminifera in deep-sea sediments is strongly correlated with the productivity of the surface ocean, and the correlation can be used to reconstruct organic carbon flux to the seafloor in the past, and hence the productivity in past oceans.
Book ChapterDOI
Reading the Sedimentary Record of the Ocean’s Productivity
TL;DR: The basic controls on ocean productivity are poorly understood both biologically and geologically as mentioned in this paper, and we do not know the global patterns of productivity very well, either with regard to the rates of primary production (that is, the amount of carbon fixed in the photic zone each year).
