Salp blooms increase carbon export 5-fold in the Southern Ocean

This study shows salp blooms increase carbon export by 5-fold in the Southern Ocean, enhancing BCP efficiency to 28%.

Molecular hydrogen is an overlooked energy source for marine bacteria

This study shows marine bacteria consume molecular hydrogen as an energy source, with H2 oxidation more active in subantarctic waters and supported by genomic and experimental evidence.

Microbial rhodopsins are increasingly favored over chlorophyll in High Nutrient Low Chlorophyll waters

The paper reports high concentrations of microbial rhodopsins in HNLC waters where chlorophyll-a is low, suggesting rhodopsin phototrophy may compensate for impaired photosynthesis and respiration.

Predation impacts late but not early community assembly in model marine biofilms.

This study examines how predation affects microbial community assembly in marine biofilms over time, finding that top-down selection impacts late-stage communities more than early ones.

Metabolic profiling suggests two sources of organic matter shape microbial activity, but not community composition, in New Zealand fjords

Depth and location influence prokaryotic and eukaryotic microbial community structure in New Zealand fjords

The paper examines microbial community structure changes in New Zealand fjords, finding depth and location influence prokaryotic and eukaryotic communities.

Are oceanic fronts ecotones? Seasonal changes along the Subtropical Front show fronts as bacterioplankton transition zones but not diversity hotspots

The paper investigates whether oceanic fronts act as ecotones by analyzing seasonal changes in bacterioplankton communities along the Subtropical Front, finding they are transition zones but not diversity hotspots.
