Summary: Bottlenose dolphins in the Chesapeake Bay show a distinct temporal pattern, mostly sighted in summer months with peak sightings in July. Their occurrence is significantly correlated to spring tidal phase, warm water temperature, and specific salinities. Using statistical modeling techniques, dolphin presence can be predicted in the Bay for future management and conservation efforts.

Summary: Plastic pollution is becoming a growing concern at coastal tourism sites, with unquantified amounts of plastic materials being discharged into coastal waters. This study in Zanzibar, Tanzania, found that plastic accounted for almost half of the waste inflow to the environment, with single-use packaging being the dominant litter item on all sampled sites. The main sources of plastic pollution in Zanzibar were residential households, building and construction, tourism, and the commercial sector.

Summary: This study investigates the variations in source, composition, and nature of aerosols in the coastal Bay of Bengal region. The study finds that aerosols in the region are influenced by the direction of winds, with different sources contributing during different seasons. The dominant contribution to aerosol composition comes from sulphate, followed by sodium, ammonium, and nitrate. The study also highlights the significant contribution of biomass burning emissions to the aerosols, and identifies the acidic nature of the aerosols.

Summary: The combination of shading and trampling from seaweed farming significantly affected the growth of Halophila stipulacea, but had no impact on the climax seagrass species Thalassia hemprichii. Seagrass cover decreased and benthic macroalgae cover increased in seaweed farm plots. Trampling had a negative effect on benthic macroalgae but seagrasses were more resistant and likely to dominate under these conditions.

Summary: This study investigates the fecal contamination dynamic at two bathing sites in Aytre Bay, France. The results reveal that fecal indicator bacteria abundances occasionally exceed the European regulatory threshold in winter, summer, and fall. The poor water quality is primarily due to high enterococci abundance. Negative correlations are found between fecal indicator bacteria and water temperature and salinity, while positive correlations are found between fecal indicator bacteria and rainfall, PO4, NO3, NO2, and SiO2, mostly in water.

Summary: This study aimed to assess the occurrence and spatial variation of industrial-use contaminants in marine biota from coastal Tanzania. The results showed differences in the concentrations of PCBs, BFRs, and organochlorine pesticides among different locations. Samples collected from Zanzibar Island had lower concentrations of PCBs and DDT but higher concentrations of hexachlorobenzene. The highest concentrations of contaminants were found in samples collected around central Dar es Salaam harbor.

Summary: This study looks into the relationship between wind speed and the occurrence of blue whales in the South Taranaki Bight region of New Zealand, finding increasing lag times between wind speed and sea surface temperature. The results indicate that the lag time is closely related to the changes in wind speed and temperature, which in turn impact the aggregation of blue whales.

Summary: This study examines the spatial bias of species occurrence records in multiple biodiversity databases in Germany and tests whether the bias in relation to land cover or land use has changed over time. The findings indicate that the proportion of records from urban areas has increased over time, while the proportion within protected areas has remained consistent. These changing sampling biases have implications for the estimation of long-term trends in species' distributions.

Summary: This study investigates the relationship between microplastic concentrations and various spatiotemporal factors in urban rivers and finds that microplastic concentrations in urban rivers are influenced by season, flow rate, and precipitation. The findings suggest that near stream factors have a stronger influence on the presence and abundance of microplastics. Fragmented microplastics are the most commonly observed morphology.

Summary: Airborne LiDAR datasets were used to measure erosion and retreat along 866 km of California coastal cliffs between 2009-2011 and 2016. The results showed that erosion exceeding the level of detection was observed at 55% of cliffs, with more erosion in northern California compared to southern and central California. Retreat rates were higher for unarmored cliffs and cliffs fronted by sandy beaches. The average cliff top retreat rates were lower than in previous studies, but the average cliff face retreat rates were similar for different time periods.

Summary: This study focused on three click types produced by white-beaked dolphins during foraging, finding differences in duration, frequency, and bandwidth between regular clicks and buzz clicks. Additionally, about 30% of the clicks had high-frequency secondary peaks, and over 90% displayed spectral peak and notch patterns between 20 and 80 kHz. These findings have implications for future quantitative assessment and acoustic identification of this species in the wild.

Summary: Illegal, unreported and unregulated (IUU) fishing is a global issue with significant economic, environmental, and social impacts. Public funding for combating IUU fishing is relatively low, and data at regional and national levels are often insufficient. A more detailed understanding of IUU fishing is needed to inform effective research and actions.

Summary: A study on the construction of wind turbines using gravity-base foundations off Blyth, Northumberland, United Kingdom found that it had no long-term effects on dolphin occurrence, but there was an increase in porpoise occurrence. The use of gravity-base foundations may represent a less impactful offshore construction method for dolphins and harbor porpoises compared to impact pile-driven turbine installation methods.

Summary: This study provides the first independent catch assessment of marine megafauna in Thailand's small-scale fisheries. The estimated annual catches in Thai small-scale fisheries include 5.66 million rays, 457,864 sharks, 2,400 sea turtles, 790 small cetaceans, and 72 dugongs. Restrictions on gillnet fishing effort, specifically crab gillnets, are necessary to prevent the extinction of threatened megafauna species.
