Sea urchin eggs contain plastid-derived components linked to development
What the study found Sea urchin eggs were found to contain plastid-derived material, including chromoplast-derived carotenoid crystals and chromoplast-specific metabolites in Arbacia lixula. The authors also report plastid DNA in the eggs of 11 other sea urchins, with diatoms appearing to be the main source. Why the authors say this matters The study suggests that…
Atmospheric oxygen links reveal higher Southern Ocean productivity
What the study found The study found that Southern Ocean net primary production is about 6.5 ± 1.36 PgC yr−1, which is higher than most CMIP6 model and satellite-based estimates but consistent with Argo oxygen-based estimates. Why the authors say this matters The authors say these productivity estimates provide quantitative benchmarks and, together with airborne…
Seagrass in Mosquito Lagoon recovered to pre-collapse levels
What the study found The study found that seagrass in Mosquito Lagoon, Florida, recovered rapidly after Hurricanes Ian and Nicole. It was still in significant decline until March 2023, then returned to pre-collapse levels in summer 2023 and later. Why the authors say this matters The authors say the findings raise awareness that Mosquito Lagoon…
HYBRID improved tidal and stratification simulation in the Yellow Sea
What the study found The hybrid z*-isopycnal vertical coordinate system (HYBRID) performed better than the z* coordinate system (ZSTAR) in simulations of Yellow Sea tides and stratification. It gave a more accurate picture of sea surface temperature, vertical thermal structure, and several tidal measures, especially in summer when the water column is strongly stratified. Why…
Atlantic δ13CDIC reconstructed with machine learning
Gaussian Process Regression reconstructs stable carbon isotope composition of dissolved inorganic carbon in the Atlantic Ocean, expanding historical data coverage 7.65-fold.
Warming changes phytoplankton macromolecular composition
Cellular model predicts how phytoplankton protein, carbohydrate, and lipid composition will shift under climate warming, with divergent regional responses that reshape marine food web nutrition.
Extreme low light triggers distinct energy states in Fragilariopsis cylindrus
Discover how Arctic polar diatoms survive extreme low light beneath sea ice by sustaining photosynthesis while uncoupling growth, maintaining metabolic readiness for rapid recovery.
Polynesian reef soundscape dataset spans multiple depth zones
Underwater acoustic recordings from Polynesian coral reefs across depth zones, capturing marine life sounds and ecosystem data for conservation research.
