Marine diazotrophs convert dinitrogen (N 2) gas into bioavailable nitrogen (N), supporting
life in the global ocean. In 2012, the first version of the global oceanic diazotroph database …

Biodiversity of phytoplankton is important for ecosystem stability and marine
biogeochemistry. However, the large-scale patterns of diversity are not well understood and …

The global nitrogen (N) cycle at the beginning of the 21st century has been shown to be
strongly influenced by the inputs of reactive nitrogen (N r) from human activities, including …

We present a numerical model of the ocean that couples a three-stream radiative transfer
component with a marine biogeochemical–ecosystem component in a dynamic three …

Phytoplankton identification and abundance data are now commonly feeding plankton
distribution databases worldwide. This study is a first attempt to compile the largest possible …

Jellyfish are increasingly recognised as important components of the marine ecosystem, yet
their specific role is poorly defined compared to that of other zooplankton groups. This paper …

Global ocean biogeochemistry models currently employed in climate change projections
use highly simplified representations of pelagic food webs. These food webs do not …

We present a summary of biomass data for 11 plankton functional types (PFTs) plus
phytoplankton pigment data, compiled as part of the MARine Ecosystem biomass DATa …

The role of nickel (Ni) in ocean biogeochemical cycles is both under-studied and
controversial. Strong correlations between Ni and organic carbon in modern and ancient …

There are a number of hypotheses concerning the environmental controls on marine
nitrogen fixation (NF). Most of these hypotheses have not been assessed against direct …
