Abstract The Indian Ocean presents two distinct climate regimes. The north Indian Ocean is
dominated by the monsoons, whereas the seasonal reversal is less pronounced in the …

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 …

Dinitrogen (N2) fixation provides the major source of reactive nitrogen in the open ocean,
sustaining biological productivity. The Indian Ocean (IO) covers 22% of the ocean surface …

A marine symbiosis has been recently discovered between prymnesiophyte species and the
unicellular diazotrophic cyanobacterium UCYN-A. At least two different UCYN-A phylotypes …

The evolution of very large body size requires a ubiquitous and abundant source of food. In
marine environments, the largest animals such as whale sharks are secondary consumers …

There have been many individual phytoplankton datasets collected across Australia since
the mid 1900s, but most are unavailable to the research community. We have searched …

Marine diazotrophs convert dinitrogen (N 2) in seawater into bioavailable nitrogen (N),
contributing approximately half of the external input of bioavailable N to the global ocean. A …

Australia's tropical waters represent predicted 'hotspots' for nitrogen (N2) fixation based on
empirical and modelled data. However, the identity, activity and ecology of diazotrophs …

Biogeochemical cycling of carbon (C) and nitrogen (N) in the ocean depends on both the
composition and activity of underlying biological communities and on abiotic factors. The …

Nitrogen (N) is an essential element for life and controls the magnitude of primary
productivity in the ocean. In order to describe the microorganisms that catalyze N …
