Summary: This study analyzed the effects of small pelagic harvests on the Gulf of California ecosystem, estimating latitudinal differences in regionalized baselines of endangered and threatened marine species attracted to fishing sets. It revealed spatial patterns in fishing effort, with higher presence of species attracted to fishing sets on the east coast. The Pennington estimator was used to compute a conservative baseline for each zone, providing insights into the distribution and abundance of marine species attracted to purse seines.

Summary: This study investigates the seasonal patterns of fish fitness for two important Mediterranean small pelagic fish species, the European anchovy and European sardine, along a latitudinal gradient in the Northwestern Mediterranean Sea. The results show spatial and temporal variations in terms of body condition, fat content, and reproduction indices, as well as stable isotopic values. Environmental variables, along with spatial and seasonal factors, mostly explain the variability in fitness for both species. This study provides insights into the interplay of the fitness of these commercial species and contributes to proactive fisheries management.

Summary: This study evaluated the population dynamics of Anchovy in the Yellow Sea large marine ecosystem using the JABBA model. The results showed that the reconfigured commercial fishery CPUE provided the most plausible assessment of the anchovy stock and should be used in fishery management. It is recommended to improve the quality and availability of fisheries statistical data worldwide for more realistic stock assessments.

Summary: The abundance of adult fish depends on the survival of early life stages, which are influenced by mesoscale events in the marine environment. This study investigated the relationship between different mesoscale processes and the catches of Pacific sardine in the Gulf of California. The results showed that eddies and coastal upwelling had significant effects on the catches, while the persistence of Tropical surface sea water intrusion also played a role. The findings highlight the importance of considering these processes in climate change scenarios to understand their impact on trophic dynamics in the Gulf of California.

Summary: This study analyzes the issues related to the efficiency of fishing vessels in managing the Pacific hake fishery. Two types of vessels, large and small, were identified using cluster analysis. Generalized linear models were used to assess efficiency variation, and the results showed that year, fishing area, net type, and vessel type significantly influenced the catch per unit of effort (CPUE). The model with interactions explained 18% of the deviance, with significant contributions from interactions between year and area, as well as depth and vessel. The study also found that large vessels were 1.5 times more efficient than small vessels.

Summary: Knowledge of the population dynamics and changes in abundance of Pacific sardine fishery is important for fishery management. This study used an integrated catch-at-age model to analyze 47 fishing seasons of Sardinops sagax in the Gulf of California. The model showed the importance of recruits in the fishery and highlighted the changes in abundance using spawning and acoustic indices. The Pacific sardine fishery in the Gulf of California has been fully exploited with a stable level of harvest.

Summary: This study presents an evaluation of the downward fluxes and composition of particulate matter in the Beagle Channel. The results show that the fluxes and composition of particulate matter differ between the western and eastern parts of the channel, with the former influenced by glacial and organic material, and the latter dominated by river inputs and phytoplankton blooms. This research contributes to understanding the impact of climate change on the biological carbon pump and land-sea connections in this high-latitude ecosystem.

Summary: Antarctic krill is a key species in the Southern Ocean and also the target of a commercial fishery. This study focuses on understanding the physical and behavioral drivers of krill movement and retention in the South Orkney Islands region through a regional modeling approach. The results suggest that oceanic transport and retention of krill are influenced by oceanographic variability and krill behavior.

Summary: This article investigates the evolution of the Sevastopol eddies using altimetry measurements and a high-resolution Nemo numerical model. The eddies can reside in the Black Sea for >3-6 months, impacting cross-shelf exchange and nutrient fluxes. The stationarity of the eddies is mainly due to the continental slope acting as a barrier, preventing cyclonic propagation.

Summary: The Sao Francisco River is an important river in Brazil, crossing the semi-arid region. A series of dams have been built along the river for hydropower, changing the flow significantly. A hydrodynamic model was used to simulate the effects of flow changes on saline intrusion in the estuary. The simulations showed an increase in mixing and decrease in river contribution after the dams were built. The results can be used by management agencies to improve water quality for human consumption.

Summary: Seasonal-scale local forcings reduce coastal pH and aragonite saturation state. The dynamics of carbonate system parameters were investigated in a coral habitat influenced by seasonal current patterns. Both Oaragonite and pH showed seasonal variations, controlled by dissolved inorganic carbon (DIC) and temperature. Ocean acidification scenarios projected a decrease in Oaragonite amplitude and an increase in hydrogen ion concentration ([H+]) amplitude.

Summary: The Vistula Lagoon, one of the two lagoons on the Polish coast, is economically and environmentally significant. This study aims to calculate the water balance of the lagoon before and after the construction of a canal through the Vistula Spit. The construction of the new connection may impact the lagoon's water balance and its biotic and abiotic environment. Data on precipitation, evaporation, inflow from the catchment, and inflow/outflow through the Strait of Baltiysk were collected for mathematical modeling. The study suggests that the construction of the new canal will not significantly alter the lagoon's water balance but may cause environmental problems.

Summary: We demonstrate that wind-driven Ekman transport enhances the advection and mixing of cells, leading to the transport of colder water from the Surface Antarctic Waters to the warmer waters of the northern Polar Front belt. This mechanism provides cells with a favorable temperature environment, allowing for specific species and community growth rates to develop blooms under non-light limiting macronutrients and iron conditions. Our findings have important implications for increased productivity in a future warming climate.

Summary: This study aimed to gain a better understanding of the role of dissolved organic matter (DOM) in the biogeochemistry of the Southern Patagonian shelf. The results showed that terrigenous input is the main source of ammonium and refractory carbon in the region, while the Antarctic Circumpolar Current contributes autochthonous DOM. Additionally, regeneration processes of nitrogen-rich water were found in the Tierra del Fuego Waters and Grande Bay regions.
