Summary: This study investigated carbon biomass, carbon-to-chlorophyll a ratio (C:Chl a), and growth rates of phytoplankton cells in Jiaozhou Bay, China during four seasonal cruises in 2017 and 2018. The results showed that diatom carbon was predominant in phytoplankton, and phytoplankton growth rates were influenced by temperature and silicate concentration in the bay.

Summary: This study analyzed the spatial distributions of atrazine and its metabolites in water, suspended particulate sediment (SPS), and surface sediment in an estuary-to-bay system. The results showed that metabolites were more actively degraded in the coastal zone and dechlorination-hydroxylation metabolites were dominant pollutants in the bay. Environmental factors have a direct influence on the transport and redistribution of metabolites during the process.

Summary: This study investigated the vertical distribution of organic matter within sea ice and found that both the bottom and upper sections of the ice contained organic matter, predominantly contributed by marine autotrophs. The particulate matter within the ice could potentially serve as an additional food source for higher trophic grazers or act as a seeding material for phytoplankton blooms during the ice melting season.

Summary: Microbial processes and bacterial community structures play crucial roles in the degradation and transformation of marine organic matter. Different sources of particulate organic matter (POM) exhibit distinct characteristics in terms of heterotrophic bacterial abundance, enzymatic activity, and community composition, reflecting the varying levels of degradation and adaptation by bacteria in response to the environmental conditions in coastal systems.

Summary: Quantitative retrieval models of total suspended solids (TSS) concentrations based on Landsat and MODIS data were developed for Jiaozhou Bay. The reliability of the retrieved TSS concentrations was evaluated, and their temporal and spatial variations were analyzed. The main factors influencing the TSS concentration in Jiaozhou Bay were identified, with wind speed being the primary factor.

Summary: The study investigated the C/N/P stoichiometry of organic matter in suspended particulate matter and surface sediment in Daya Bay, China. It found that the surface sediment in the inner bay had higher contents and ratios of total organic C, N, and P. The distribution of C/N/P stoichiometry differed between suspended particulate matter and surface sediment, showing the influence of terrigenous input and thermal effluent from a nuclear power plant.

Summary: This study quantifies the spatial variability of suspended particulate matter (SPM) concentrations in San Francisco Bay using satellite and shipboard remote sensing, showing that point sampling underestimates the variability within a 5 km scale. The spatial structure and variability in the bay change seasonally based on freshwater inflow, tidal state, and wind speed.

Summary: Temperature plays a significant role in affecting the physiological traits of marine plankton. Elevated temperature led to a decrease in Chl a concentration and the effect of temperature on the POC and PON contents of plankton is affected by the availability of nitrate. Diatoms were the dominant phytoplankton group. Ocean warming has the potential to increase the POC contents of marine plankton, which may increase their ability to absorb atmospheric CO2 and alleviate global warming.

Summary: Water transparency is crucial for understanding the optical properties of coastal waters. In this study, we developed a regional linear corrected estimation model for water transparency based on mathematical and mechanical models. Our findings suggest that variations in water transparency are influenced by solar zenith angle, tides, and wind force. Additionally, air temperature was found to have a significant impact on water transparency. Human activities were also identified as a potential factor affecting water environment changes.

Summary: Transparency of coastal waters, measured by Secchi disk depth, is influenced by solar zenith angle and tides in Jiaozhou Bay. An increasing trend in transparency, particularly inside the bay, is observed over the years, with air temperature playing a significant role. Human activities are also recognized as contributing factors to changes in water quality.

Summary: The study reveals that dissolved organic nitrogen (DON) from terrestrial input exacerbates eutrophication and induces harmful algal blooms in Jiaozhou Bay. The addition of hydrophilic (Hic) and low molecular weight (LMW) DON significantly increases algal growth, reduces community biodiversity, and provides a competitive advantage for Skeletonema costatum. These effects are further intensified in autumn with increasing temperature. Hic DON has higher bioavailability than LMW DON.

Summary: The study revealed that seasonal variations in the source of suspended particulate organic matter in Zhanjiang Bay are influenced by the monsoon, with terrigenous sources dominating in summer and marine organic matter being the major source in winter. Additionally, the spatial distribution of delta N-15 values is complex and varies depending on season and location.

Summary: Land-ocean interactions are important in transporting and accumulating organic carbon in marine sediments. This study in the Jiaozhou Bay found significant contributions of terrestrial, marine, and anthropogenic sources to sedimentary organic carbon. Terrestrial biomarkers were predominant in the river, while marine biomarkers showed different distribution patterns.
