Bio-GO-SHIP: Linking marine biodiversity and biogeochemistry

The Bio-GO-SHIP program aims to integrate the latest biological observing technologies into the Global Ocean Ship-based Hydrographic Investigation Program (GO-SHIP, http://go-ship.org/). GO-SHIP runs a global repeat-section effort, wherein reference sections that transect major ocean regions are sampled every decade to observe global changes. Bio-GO-SHIP measurements will include optical, flow cytometric, metagenomic and metatranscriptomic, and particulate sampling. Compared to previous global ocean sequencing efforts, Bio-GO-SHIP will sample biological parameters at high spatial and vertical resolution, with ‘omic samples being taken approximately every degree, or approximately 26.

Transcriptional patterns identify resource controls on the diazotroph Trichodesmium in the Atlantic and Pacific oceans

The N2-fixing cyanobacterium *Trichodesmium* is intensely studied because of the control this organism exerts over the cycling of carbon and nitrogen in the low nutrient ocean gyres. Although iron (Fe) and phosphorus (P) bioavailability are thought …

Shifting metabolic priorities among key protistan taxa within and below the euphotic zone

A metatranscriptome study targeting the protistan community was conducted off the coast of Southern California, at the San Pedro Ocean Time‐series station at the surface, 150 m (oxycline), and 890 m to link putative metabolic patterns to distinct …

Virus-host relationships of marine single-celled eukaryotes resolved from metatranscriptomics

Establishing virus–host relationships has historically relied on culture-dependent approaches. Here we report on the use of marine metatranscriptomics to probe virus–host relationships. Statistical co-occurrence analyses of dsDNA, ssRNA and dsRNA …

Functional group-specific traits drive phytoplankton dynamics in the oligotrophic ocean

A diverse microbial assemblage in the ocean is responsible for nearly half of global primary production. It has been hypothesized and experimentally demonstrated that nutrient loading can stimulate blooms of large eukaryotic phytoplankton in …

Metatranscriptome analyses indicate resource partitioning between diatoms in the field

Diverse communities of marine phytoplankton carry out half of global primary production. The vast diversity of the phytoplankton has long perplexed ecologists because these organisms coexist in an isotropic environment while competing for the same …
