Diazotrophy as the main driver of the oligotrophy gradient in the western tropical South Pacific Ocean: results from a one-dimensional biogeochemical–physical coupled model [PDF]
The Oligotrophy to UlTra-oligotrophy PACific Experiment (OUTPACE) cruise took place in the western tropical South Pacific (WTSP) during the austral summer (March–April 2015). The aim of the OUTPACE project was to investigate a longitudinal gradient of

Abstract Introduction Polycyclic aromatic hydrocarbons (PAHs), a class of petroleum‐derived compounds known for causing cellular damage and for their recalcitrant behavior, severely limit effective biodegradation. Arbuscular mycorrhizal fungi (AMF) from oil‐contaminated environments can mitigate PAH‐related stress on host plants, highlighting the ...

Microbial communities in dark oligotrophic volcanic ice cave ecosystems of Mt. Erebus, Antarctica
The Earth’s crust hosts a subsurface, dark, and oligotrophic biosphere that is poorly understood in terms of the energy supporting its biomass production and impact on food webs at the Earth’s surface.

The fate of a southwest Pacific bloom: gauging the impact of submesoscale vs. mesoscale circulation on biological gradients in the subtropics [PDF]
The temporal evolution of a surface chlorophyll a bloom sampled in the western tropical South Pacific during the 2015 Oligotrophy to UlTra-oligotrophy PACific Experiment (OUTPACE) cruise is examined.

Abstract The subtropical North Atlantic is a key region for ocean carbon cycling despite its relatively small spatial extent. Here we present a high‐resolution transect (23°–27°N; ∼2° longitude spacing) across the North Atlantic Subtropical Gyre, integrating physical, chemical, and microbial observations to examine how hydrography and nutrient ...

Nano-Sized and Filterable Bacteria and Archaea: Biodiversity and Function
Nano-sized and filterable microorganisms are thought to represent the smallest living organisms on earth and are characterized by their small size (50–400 nm) and their ability to physically pass through <0.45 μm pore size filters.

Thresholds of terrestrial nutrient loading for the development of eutrophication episodes in a coastal embayment in the Aegean Sea [PDF]
Thresholds of terrestrial nutrient loading (inorganic N and P) for the development of eutrophication episodes were estimated in an enclosed embayment, the gulf of Kalloni, in the Aegean, Eastern Mediterranean.
