The marine microbiome contributes to nearly half of our planet’s net primary production. It plays a central role in the ocean’s carbon cycle through both passive and active release of metabolites into seawater, forming a pool of dissolved compounds known as the marine exometabolome.

The capacity of planktonic marine microorganisms to actively seek out and exploit microscale chemical hotspots has been widely theorized to affect ocean-basin scale biogeochemistry, but has never been examined comprehensively in situ among natural microbial communities. Here, using a field-based ...

In June 12 – 18, 2021, marine microbial samples were collected in East Sound, WA, USA every 4 hours. This high temporal resolution sampling effort captured the initiation of a Chaetoceros socialis bloom. A metaproteomic data dependent analysis was performed on the 6 days of the time series preceding...

Global metaproteomic analyses of microbial biomass from the upper water column of the Central Pacific Ocean. This dataset was used as a discovery dataset to identify peptide biomarkers for cyanobacterial populations for use in targeted metaproteomic calibrated multiple reaction monitoring (MRM) anal...

This study uses 16S rRNA and 16S rRNA gene to investigate variation in the active microbiome across latitudinal scales in the Atlantic Ocean.
An Autonomous Underwater Vehicle (AUV) and large volume underwater pumps were used to collect microbial biomass from offshore waters of the Sargasso Sea, from surface waters and into the deep ocean. Seawater collection was performed along a transect in the western North Atlantic Ocean beginning near...

The viral shunt is a fundamental ecosystem process which diverts the flux of organic carbon fixed through photosynthesis during algal bloom events from heterotrophic grazers to bacteria. Through the extracellular release of metabolites, lytic viral infections supply 2-10% of photosynthetically fi...
