Summary: A dynamic energy budget model was used to study the effects of ocean acidification on Atlantic surfclam bioenergetics. The simulation results showed that future warming and acidification conditions would result in faster growth and increased energy allocation for reproduction in young surfclams, but a reduction in maximum shell length and energy allocated to reproduction was observed by the beginning of the 22nd century according to the RCP 8.5 scenario.

Summary: The Atlantic surfclam is a promising candidate for species diversification in the US Northeast. However, gaps in the literature have left aquaculture practitioners without a complete understanding of how to best cultivate this species. Controlled experiments were conducted to evaluate the efficacy of different gear types and conditions, and results showed that multiple methods can effectively produce commercial-scale quantities of surfclams.

Summary: This study applied an existing integrated bioeconomic model to evaluate the potential economic effects of offshore wind development on the Atlantic surfclam fishery. By simulating fishing activity and economic outcomes under different offshore wind energy development scenarios, the study found that spatial restrictions and changes in fishing effort distribution would decrease revenues for fishing vessels and processors and increase fishing costs.

Summary: Rising water temperatures have caused the Atlantic surfclam to shift its range to areas where ocean quahogs are already present, resulting in restrictions on fishing activities and potential economic disruption. Wind energy development further limits the fishery, and simulations demonstrate the consequences of species overlap and fishing constraints. The study highlights the challenges faced by the Atlantic surfclam fishery as climate change and ocean management evolve.

Summary: Climate change impacts on fishery resources in the warm-temperate Southwest Atlantic Ocean have been assessed. The study found that most species showed moderate or high sensitivity to climate change, with mollusks and chondrichthyans being the most sensitive groups. The stock and conservation status of the species greatly influenced their sensitivity. The study also revealed that although past landings were mostly from relatively climate-resilient species, future catches and benthic fisheries may be at risk due to the high sensitivities of some exploited species and potential changes in species distribution.

Summary: Warming of the Mid-Atlantic continental shelf has caused a range shift of the Atlantic surfclam, resulting in species overlap with the ocean quahog. An at-sea survey was conducted to assess the fishable concentrations of surfclams and quahogs in the overlap region. The analysis revealed depth-dependent density changes and temperature-dependent size differences between the two species. This study emphasizes the potential economic disruption of fisheries and the importance of regulatory changes to accommodate mixed catches.

Summary: The study suggests that a small fraction of ancient CH4-derived carbon is being assimilated into the dissolved inorganic radiocarbon in the U.S. Mid-Atlantic Bight, especially in areas with elevated CH4 concentration and active gas seepage. While the short-term influence of CH4 oxidation on ocean pH is small, over longer time scales, the oxidation of ancient CH4-derived carbon could contribute to deepwater acidification on a global scale.

Summary: Shelfbreak exchange processes, particularly the Salinity Maximum Intrusion, have been extensively studied in the Middle Atlantic Bight. Recent data suggests that middepth intrusions are occurring more frequently and with greater salinity difference from ambient water compared to previous studies. The increase in frequency may be linked to a recent regime shift in the annual formation rate of Warm Core Rings by the Gulf Stream. Properly resolving this process in numerical simulations is necessary to account for salt budgets for the continental shelf and slope.

Summary: Climate-driven distributional shifts have been well-documented for fisheries resources along the East Coast of the United States, yet little attention has been given to adjacent estuarine systems. This study analyzed data collected from 2008 to 2019 to explore temporal patterns and environmental drivers of the estuarine-coastal ocean exchange in the Mid-Atlantic for eight economically and ecologically important species. The results demonstrate that climate drivers have different impacts on estuarine-coastal ocean exchange and the impacts vary spatially.

Summary: Many marine species are shifting their distributions in response to changing ocean conditions, which poses challenges for fisheries management. Species distribution models (SDMs) are used to project future distributions, but there is concern that fishery-dependent data may bias predictions. Understanding the strengths and limitations of SDMs based on fishery-dependent data is critical due to limited resources for fishery-independent surveys.

Summary: Warm Core Rings (WCRs) have significant impacts on the shelf flow and temperature. Rings with higher rotational velocities and closer to the shelf have greater influence, including reversing the direction of flow at the shelf break. The seasonal variability affects the temperature impact of rings on the shelf, with associated upwelling effects on the shelf flow.

Summary: The study found that larval Atlantic surfclam exhibited a hormetic response at moderate CO2 concentrations, showing significantly increased shell height and growth rates, as well as a higher metamorphosis rate. Although there was no significant difference in survival rates, Atlantic surfclam showed some tolerance to ocean acidification at moderate CO2 concentrations.

Summary: The continental shelf of the West Antarctic Peninsula is characterized by strong alongshore hydrographic gradients influenced by warm Bellingshausen Sea to the south and cold Weddell Sea water to the north. The seasonal and interannual variability in along-shore exchange processes control the spatial structure and variability of glacier retreat and other physical and biochemical factors along the shelf. The wind conditions and hemispheric-scale climate processes play a key role in modulating the amount of cold water flowing into the central West Antarctic Peninsula from Bransfield Strait, highlighting the significance of along-shore exchange in regulating hydrographic properties in the region.

Summary: Diel vertical migration is a common behavior in zooplankton populations, where they migrate to deepwater during the day and return to the surface at night. This study focuses on a subsurface eddy in the Palmer Deep Canyon, which increases the retention of migrating zooplankton in the region. The presence of the eddy improves residence times and contributes to the establishment of a biological hotspot.

Summary: Atlantic surfclams and ocean quahogs are large-bodied clams that dominate the biomass on the Mid-Atlantic continental shelf. However, their numerical abundance is not dominant in the benthic community and they tend to be patchily distributed. Estimating overall abundance and biomass is challenging due to the unique characteristics of individual clams and their distribution habits. Proper sampling and survey strategies are crucial to prevent undersampling and bias. Moreover, consistent sample collection methods are essential to compare data across multiple surveys, improving regional assessments of population status and changes. This paper provides recommendations to enhance the quality of surveys and facilitate direct comparison of data among different surveys and teams.

Summary: Blue crabs (Callinectes sapidus) in the US mid-Atlantic Bight have unpredictable and variable recruitment, so understanding their larval development and dispersal is important. This study used a simulation model to investigate the effects of swimming behavior, current systems, and mixing on larval transport. Results showed that larval transport is mainly influenced by wind speed, but behavioral traits also play a significant role. Swimming larvae can maintain a near-surface position and have more control over their vertical distribution compared to passive particles. These findings highlight the importance of larval swimming ability and behavioral variability in blue crab larval dispersal.

Summary: By combining in situ data, satellite remote sensing, and a physical-biogeochemical model, the deoxygenation process in the Patagonian fjords was revealed for the first time. Deoxygenation was associated with the advection of equatorial subsurface water, and the importance of the Peru-Chile undercurrent in transporting this subsurface water into the fjords was confirmed. The recent deoxygenation in the northern Patagonian fjords emphasizes the need to study dissolved oxygen and its impacts on marine organisms.

Summary: Estuaries provide important habitat for eastern oysters, with varying salinity conditions affecting oyster growth. Experiment 1 found that transplantation to higher salinity led to increased growth, while oyster spat from the lowest salinity had the highest overall growth. Shell morphology did not affect growth. Experiment 2 showed that higher initial salinity and lower final salinity led to increased growth, highlighting the importance of early postsettlement salinity stress on oyster growth. These findings have significant implications for understanding oyster stock resilience in the face of climate change.

Summary: A study finds that global mean sea level has been accelerating since the 1960s, but detecting this locally is difficult due to natural variability. However, tide gauge records along the U.S. Southeast and Gulf coasts show unprecedented rates of sea level rise (>10 mm yr(-1) since 2010). The acceleration is primarily induced by an ocean dynamic signal exceeding the externally forced response, and is compounded by wind driven Rossby waves.

Summary: The Atlantic surfclam fishery in the U.S. Northeast continental shelf is highly vulnerable to the impacts of offshore wind energy development due to overlapping fishing grounds and wind energy lease areas. The installation of wind energy turbines and cables can restrict or eliminate federal assessment surveys, leading to changes in stock assessments and increased uncertainty in setting fishing quotas. A modeling framework was used to assess the impact of excluding the surveys from wind energy lease areas, which resulted in lower spawning stock biomass estimates and increased fishing mortality.
