Short summary
Nutrient levels govern oceanic primary production, but measuring them is labor-intensive and costly. To address this, we used machine learning models to learn the hidden relationships between easy-to-measure ocean properties (like temperature and salinity) and nutrient levels. Applying this model, we created ~ 470 million nutrient data points across the North Pacific from 1895 to 2024. This data will help to understand nutrient and marine ecosystem variability under climate change.

We investigated the abundance, diversity, composition, and distribution of ostracods (a meiobenthic group) and their interactions with eutrophication and pollution through high-resolution sampling of surface sediment in Deep Bay, a small semi-enclosed riverine bay adjacent to two of the world’s most populated cities: Hong Kong and Shenzhen. The results support the idea that ostracods are a useful bioindicator of coastal benthic ecosystems shaped by distinct environmental problems.

Short summary
The biodiversity and abundance of benthic foraminifera tend to increase with distance within a transect from the Rainbow hydrothermal vent field. Miliolids dominate closer to the vents and may be better adapted to the potentially hydrothermal conditions than hyaline and agglutinated species. The reason for this remains unclear, but there are indications that elevated trace-metal concentrations in the porewater and intrusion of acidic hydrothermal fluids could have an influence on the foraminifera.

Short summary
This study reports higher nutrient release in fish farming system compared to river inputs and other sources with implications for coastal environment. DIN and DIP variation in Sansha Bay are dominated by mariculture activity relative to river input during spring. The N/P budget shows that 52.8 ± 4.7 % of DIN and 33.0 ± 3.7 % of DIP released from fish feeds exceeded other nutrient inputs. Co-culture strategies (e.g., of fish, kelp and oysters) allow effective mitigation of environmental impacts.

We distinguished particulate organic carbon (POC) export fluxes out of the nutrient-depleted layer (NDL) and the euphotic zone. The amount of POC export flux at the NDL base suggests that the NDL could be a hotspot of particle export. The substantial POC export flux at the NDL base challenges traditional concepts that the NDL was limited in terms of POC export. The dominant nutrient source for POC export fluxes should be subsurface nutrients, which was determined by 15N isotopic mass balance.

We reconstructed monthly sea surface pCO2 data with a high spatial resolution in the South China Sea (SCS) from 2003 to 2020. We validate our reconstruction with three independent testing datasets and present a new method to assess the uncertainty of the data. The results strongly suggest that our reconstruction effectively captures the main features of the spatiotemporal patterns of pCO2 in the SCS. Using this dataset, we found that the SCS is overall a weak source of atmospheric CO2.

Fe and P are key factors controlling the biogeography and activity of marine N2-fixing microorganisms. We found lower abundance and activity of N2 fixers in the northern South China Sea than around the western boundary of the North Pacific, and N2 fixation rates switched from Fe–P co-limitation to P limitation. We hypothesize the Fe supply rates and Fe utilization strategies of each N2 fixer are important in regulating spatial variability in community structure across the study area.

In situ oxygen consumption rates were estimated for the first time during destruction of coastal hypoxia as disturbed by a typhoon and its reinstatement in the South China Sea off the Pearl River estuary. The reinstatement of summer hypoxia was rapid with a comparable timescale with that of its initial disturbance from frequent tropical cyclones, which has important implications for better understanding the intermittent nature of coastal hypoxia and its prediction in a changing climate.

This study reconstructs a complete field of summer sea surface partial pressure of CO2 (pCO2) over the South China Sea (SCS) with a 0.5° resolution in the period of 2000–2017 using the scattered underway pCO2 observations. The spectral optimal gridding method was used in this reconstruction with empirical orthogonal functions computed from remote sensing data. Our reconstructed data show that the rate of sea surface pCO2 increase in the SCS is 2.4 ± 0.8 µatm yr-1 during 2000–2017.

Through a comprehensive investigation, we observed differential niche partitioning among diverse ammonia-oxidizing archaea (AOA) sublineages in a typical subtropical estuary. Distinct AOA communities observed at DNA and RNA levels suggested that a strong divergence in ammonia-oxidizing activity among different AOA groups occurs. Our result highlights the importance of identifying major ammonia oxidizers at RNA level in future studies.

Short summary
Our results suggest coccolithophore calcite accounts for a major fraction of PIC (particulate inorganic carbon) standing stocks in the western North Pacific, with a markedly higher contribution in the oligotrophic subtropical gyre than in the Kuroshio–Oyashio transition region, which highlights the importance of coccolithophores for PIC production in the pelagic ocean, particularly in oligotrophic ocean waters.
