Phago-mixotrophy of small eukaryotic phytoplankton might alleviate iron limitation in HNLC Southern Ocean

The paper measures carbon fixation rates and taxonomic composition of small phytoplankton in different oceanic regions, suggesting phago-mixotrophy may help alleviate iron limitation in certain populations.

Prey size spectra and predator to prey size ratios of southern ocean salps

This study examines the prey size spectra and predator-to-prey size ratios of southern ocean salps, finding that picoplankton contribute minimally to their diet compared to nanoplankton.

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%.

Quantifying biological carbon pump pathways with a data-constrained mechanistic model ensemble approach

This paper develops a data-constrained mechanistic model to quantify biological carbon pump pathways, finding that sinking particles and vertical mixing are more significant than active zooplankton transport.

Seasonal variability in carbon:234thorium ratios of suspended and sinking particles in coastal Antarctic waters: Field data and modeling synthesis

This study examines seasonal changes in carbon:thorium ratios in Antarctic coastal waters, identifying fecal pellets and diatom blooms as key factors influencing these ratios through field data and modeling.

Taxon-specific phytoplankton growth, nutrient utilization, and light limitation in the oligotrophic Gulf of Mexico

The paper measures light and nitrogen limitation in Gulf of Mexico phytoplankton and identifies taxon-specific nutrient utilization patterns using Bayesian data assimilation.

Trade-offs between risks of predation and starvation in larvae make the shelf break an optimal spawning location for Atlantic Bluefin tuna

This study models larval Atlantic Bluefin tuna mortality to show that spawning near the shelf break balances predation and starvation risks, optimizing larval survival.

Investigating equations for measuring dissolved inorganic nutrient uptake in oligotrophic conditions

This study evaluates nutrient uptake equations under oligotrophic conditions, finding that equations accounting for nutrient regeneration are more accurate, especially at low concentrations with high uptake.

Plankton food webs of the Gulf of Mexico spawning grounds of Atlantic Bluefin tuna

The paper models the Gulf of Mexico food web to show microbial loop dominance and ABT larvae's reliance on zooplankton for trophic transfer.

The Importance of Mesozooplankton Diel Vertical Migration for Sustaining a Mesopelagic Food Web

The paper uses ecological and biogeochemical data to model carbon fluxes between ocean zones, finding that mesozooplankton diel vertical migration significantly contributes to carbon transfer to the mesopelagic zone.
