The reliability of paleoproductivity proxies must be determined before assessing the role of
the oceanic carbon (C) cycle in affecting past climate changes. We compare …

One of the best‐studied aspects of the K‐Pg mass extinction is the decline and subsequent
recovery of open ocean export productivity (eg, the flux of organic matter from the surface to …

Marine biological productivity has been invoked as a possible climate driver during the early
Paleogene through its potential influence on atmospheric carbon dioxide concentrations …

Surface ocean biological productivity was reconstructed for oxygen isotope stages 1 and 2
in 5 cores from the eastern equatorial Pacific using a newly developed proxy based on …

We evaluate phosphorus (P) and biogenic barium (bio‐Ba) as nutrient burial and export
productivity indicators for the Late Cretaceous and early Paleogene, combining these with …

We examine whether or not a relationship exists between the late Miocene carbon isotope
shift (∼ 7.6–6.6 Ma) and marine productivity at four sites from the Indian and Pacific Oceans …

Based on organic carbon accumulation rates, nine time slices of oceanic export
paleoproductivity (P new) are presented which depict the variability of P new on a global …

Although marine productivity is a key parameter in the global carbon cycle, reliable
estimation of productivity in ancient marine systems has proven difficult. In this study, we …

The seminal proposition by Arrhenius (1952) that colder periods favor higher productivity
oceans than warmer ones, together with the relatively recent hypothesis linking the surface …

Export production is an important component of the carbon cycle, modulating the climate
system by transferring CO2 from the atmosphere to the deep ocean via the biological pump …
