Summary: This paper summarizes observations of wind and surface gravity waves in Long Island Sound and explores the relationship between significant wave height and wind speed and direction. It shows that waves respond asymmetrically to wind direction, being larger and having longer periods when the wind is from the east compared to the west. The data support fetch limited wave growth predictions for westerly winds, but suggest that an effective fetch of approximately 30 km is needed for easterly winds.

Summary: The geometry of the Long Island Sound (LIS) affects the propagation of waves, leading to differences between western and eastern areas. The mechanisms governing wave formation and dissipation in the LIS are not well understood. Existing meteorological models fail to accurately capture wave statistics due to low resolution and limited ability to resolve the LIS coastline, thus modification of wind fields using in situ wind observations is necessary.

Summary: Cities like New York and areas downwind have poor air quality due to pollution generated by human activity. Ozone (O-3), a harmful pollutant, is produced in the atmosphere from photochemical reactions involving volatile organic compounds (VOCs) and nitrogen oxides (NOx). Aircraft measurements of VOCs obtained during an O3 event in May 2017 over the New York City metropolitan area, Long Island Sound, and Connecticut show concentrations of O-3 exceeding 100 ppb between similar to 200 and 500 m above the surface.

Summary: Coastal marshes are threatened by human wastewater containing high nitrogen levels, leading to eutrophication and degradation of these valuable ecosystems. Analysis of a salt marsh sediment core shows a positive correlation between 8N15 levels, indicative of human population rise, and population over three centuries. This research suggests that refining the relationship between population and nitrogen loads could help protect our coastal ecosystems.

Summary: This study examines the relationship between microplastics and eastern oysters in Long Island Sound. The results show low concentrations of microplastics in oysters and their surrounding environment, with no clear correlation. This suggests that oysters are not a reliable bioindicator species for microplastic pollution.

Summary: The dinoflagellate Gyrodinium jinhaense, originally found in Korean coastal water, has unclear global distribution and genomic characteristics. A transcriptome of a closely related species, Gyrodinium jinhaense strain AP17, was sequenced and analyzed, providing valuable insights into genes related to grazing, energy generation, genome architecture, and protein synthesis. This study represents a foundational step for future genomics and toxicological research on Gyrodinium species.

Summary: Digisonde observations over Ascension Island show that post-midnight spread F is more common during solar minimum years, with a pronounced seasonal variation. The study also reveals a connection between the sudden stratospheric warming in the Southern Hemisphere and higher occurrence of spread F.

Summary: The research examined seasonal deep-water hypoxia in western Long Island Sound and found that bottom DO fluctuations are influenced by tidal advection, while surface DO fluctuations are influenced by biological production. By analyzing continuous timeseries data and weekly cruise surveys, factors such as the duration and area of hypoxia were studied.

Summary: This study presents a modeling study of internal tides propagating around an idealized island. It shows that subcritical slope has the greatest potential for creating favorable conditions for benthic organisms through enhanced upwelling. These findings are important for understanding the propagation of internal waves and the characteristics of water flow around islands.

Summary: In this study, complex Love numbers of long-period zonal tides were estimated for the first time using the optimal sequence estimation method with GPS displacements. The results allow for the determination of lower mantle anelastic parameters and material-dependent parameters, and can be used to construct attenuation and velocity models of the Earth's interior.

Summary: In 1999, the American lobster population in the Long Island Sound experienced a severe mortality event, causing profound and lasting impacts on individuals, their families, and communities. The lack of effective and comprehensive recovery or assistance plans, combined with challenges impeding fishery diversification significantly hindered the ability of lobstermen to adapt. The lessons learned from this case study can inform future action to address impacts and maximize adaptive capacity in fishing communities facing environmental changes and shifts in species distributions due to climate change and other anthropogenic factors.

Summary: How flooding affects home values can significantly impact economic recovery and financial systems at both local and global levels. However, our understanding of the complex relationship between flood insurance, community risk perception, and past flooding events in shaping future housing prices is still limited. Through a socio-environmental model, this study examined the long-term effects of flooding on housing values in coastal areas of New York, Connecticut, and New Jersey from 1970 to 2021. The findings suggest that the initial economic impact of Hurricane Sandy was mitigated by the National Flood Insurance Program (NFIP), but the region experienced a sustained decline in home values afterwards. The study also found that the changes in housing prices were influenced by past flooding events and the level of NFIP participation. A better understanding of these relationships can inform more equitable resource allocation and policy interventions to reduce flooding risk.

Summary: The movement of the drifting ice and tidally generated trapped motion around Hopen Island is described using satellite images and experiments with drifting buoys. An analytical solution is applied to investigate the trapping phenomenon, achieving a general solution through the superposition of incident and reflected waves. The simulated drift of Lagrangian water particles reproduces well the observed trapped motion near Hopen Island.

Summary: This paper leverages historical wave height data and correlations with wind speed and direction to build statistical models that fill data gaps and extend the record length of coastal wave observations. A threshold regression model is developed to capture nonlinear associations using lagged wind speed as a threshold parameter, and lagged predictors based on an empirical wind-wave relationship. The model also addresses residual conditional heteroscedasticity using a GARCH model. The approach allows for hindcasting wave heights using wind information from a coastal station, enabling the estimation of reliable return values for improved coastal protection structure design.
