    An assessment of variations in phytoplankton nutrient limitation in the tropical Pacific over the past two decades finds that phytoplankton iron limitation is more stable in response to ENSO dynamics than models predict.

    In situ experiments have demonstrated chemotaxis of marine bacteria and archaea towards specific phytoplankton-derived dissolved organic matter, which leads to microscale partitioning of biogeochemical transformation in the ocean.

    A continuous, multi-century record of subarctic Atlantic marine productivity shows that a marked decline in net primary productivity has occurred across the subarctic Atlantic basin over the past two centuries.

    Phytotransferrin, a functional analogue of transferrin, has an obligate requirement for carbonate to bind iron, which suggests that acidification-driven declines in the concentration of seawater carbonate ions may negatively affect diatom iron acquisition.

    Members of a family of marine dsDNA non-tailed bacterial viruses have short, 10-kb genomes, infect a broader range of hosts than tailed viruses and belong to the double jelly roll capsid lineage of viruses, which are associated with diverse bacterial and archaeal hosts.

    An analysis of 24 coral reef viromes challenges the view that lytic phage are believed to predominate when the density of their hosts increase and shows instead that lysogeny is more important at high host densities; the authors also show that this model is consistent with predator–prey dynamics in a range of other ecosystems, such as animal-associated, sediment and soil systems.

    Gene expression of microbes in anaerobic sediment from the Peru Margin at depths up to 159 metres below the sea floor is analysed: anaerobic metabolism of amino acids, carbohydrates and lipids are seen to be the dominant metabolic processes, and genes associated with cell division are found to be correlated with microbial cell concentration, suggesting that ongoing cell division contributes to biomass turnover.

    On the basis of data from other subglacial environments and simulations of the accumulation of methane hydrate in Antarctic sedimentary basins, it seems there could be unsuspected, large stores of methane beneath the Antarctic Ice Sheet.

    Using newly derived genome sequences of 137 marine microbial isolates as well as previously obtained genome and metagenome data, this study presents a functional analysis of picoplankton residing in the ocean's surface layer.

    Phytoplankton biomass is a crucial measure of the health of ocean ecosystems. An impressive synthesis of the relevant data, stretching back to more than 100 years ago, provides a connection with climate change.
