Here we compare three PTE extraction methods that are widely used in foraminiferal pollution studies. Evident discrepancies between methods were observed when diversity indices and relative abundances were influenced differently by the same and, in some cases, by different PTEs depending on the method. This was reflected in the canonical correspondence analysis (CCA), where Cr-Ni (Method B) and Zn-Pb-Cu (Method C) had a respective positive and negative influence over the foraminiferal relative abundances while no positive correlations were observed for Method A. These discrepancies stem from each method extracting different concentration levels of the same PTE from the same sediment samples. We recommend bioavailable PTEs to be extracted from the following fractions: (1) mud-bound from Method A (F1- exchangeable); (2) organic-bound from Method B (F3- oxidizable); and (3) completely avoid using Method C.

TY - AU - Jundt, EvaLynn AU - Hu, Xinping AB - Historical water column carbonate measurements have been scarce in the Gulf of Mexico (GOM); thus, the progression of ocean acidification (OA) is still poorly understood, especially in the subsurface waters. In the literature, statistical models, such as multiple linear regression (MLR), have been created to fill OA data gaps in different ocean regions. Additionally, machine learning techniques such as random forest (RF) have been used in model creations for both the open ocean and marginal seas. However, there is no statistical model for subsurface carbonate chemistry parameters (i.e., pH and ΩArag) in the GOM. By creating models with various architectures built upon the relationships between commonly measured hydrographic properties (e.g., salinity, temperature, pressure, and dissolved oxygen or DO) and carbonate chemistry parameters (e.g., pH and aragonite saturation state, or ΩArag), data gaps can be potentially filled in areas with insufficient sampling coverage. In this study, two statistical models were created for pH and ΩArag in the northwestern GOM (nwGOM) within the range of 27.1–29.0˚N and 89–95.1˚W using both MLR and RF methods. The calibration data used in the models include salinity, temperature, pressure, and DO collected from seven cruises that took place between July 2007 and February 2023. The models predict ΩArag with R2 ≥ 0.94, mean square error (MSE) ≤ 0.04, and pH with R2 ≥ 0.93, MSE ≤ 0.0005. Both the MLR and RF models perform similarly. These models are valuable tools for reconstructing pH and ΩArag data where direct chemical observations are absent but hydrographic information is available in the nwGOM. Nevertheless, potential shifts in circulation, water mass changes, and accumulation of anthropogenic CO2 need to be accounted for to improve and revise these models in the future.

AU - Temby, Owen AB - It is well known that publications with collaborators from external institutions increase citations. This effect scales with spatial distance. There are also many barriers to long-distance collaborations, including linguistic differences, funding constraints, and the incremental costs of remote collaboration. This paper uses the Gulf of Mexico as a case study to examine long-distance research collaboration because it consists of three countries with diverse development levels and two prominent diplomatic languages, within a singular regional ecosystem of tremendous natural and economic value. This paper uses bibliometric network analysis to examine scientific research article co-authorship in the Gulf of Mexico from 2000 to 2018. The results reveal that, although inter-organizational co-authorship has increased, significant fragmentation exists between the U.S.A, Mexico, and Cuba. Large differences in technological and organizational proximity as well as research capacity between US and Mexican states in the Gulf of Mexico may make collaboration more difficult compared to other transboundary settings, such as the US-Canadian border. Centrally located organizations in the network, such as NOAA, have played a prominent role in cross-institutional research, suggesting a capacity to bridge political entities in the Gulf of Mexico.

We explore the potential oceanic emissions of NO and its impacts using a global chemistry-climate model with a newly developed oceanic NO emission inventory, considering the abiotic photochemical production of NO in the seawater. The results are evaluated using global observations from the NASA Atmospheric Tomography Mission (ATom). We propose that the photochemical production of NO from the photolysis of dissolved inorganic nitrite and nitrate in the surface seawater could lead to an oceanic NOx source of ∼3 Tg N per year, which could explain the missing NO in the remote marine boundary layer. This potential oceanic NO source leads to a small but potentially widespread increase in surface ozone and hydroxyl radicals in the remote marine environment, altering our understanding of the role the remote marine atmosphere plays in the global system. Further, the role of the photolysis of nitrate aerosols may be overestimated in recent studies and warrants further investigation.

Species such as Shewanella algae and Shewanella putrefaciens are known to cause soft tissue necrosis and invasive infections from marine exposure. Seafood consumption has been linked to Shewanella illnesses, raising concerns about public health risks. Seafood consumption has been on the rise in recent years due to its reported benefits and overall positive health and nutritional perception of consumers. However, an emerging seafood pathogen, Shewanella spp., threatens the safety of these products. This review synthesizes existing data on: (i) the prevalence of potentially pathogenic Shewanella spp. in oysters and seawater from locations around the world, (ii) the antibiotic resistance profiles of isolates from diverse geographic regions, and (iii) processing treatments to reduce Shewanella in seafoods. Findings suggest that Shewanella spp. are widespread in seafood and marine environments. Studies have also shown that over time Shewanella spp. have become more resistant to β-lactam antibiotics such as penicillin, ampicillin, and vancomycin. This growing antibiotic resistance is largely attributed to the overuse and misuse of antibiotics in aquaculture and agriculture, contributing to the emergence of multiple-antibiotic-resistant (MAR) bacteria in seafood. The presence of MAR bacteria limits treatment options in the event of infection by Shewanella and other pathogenic bacteria underscoring the need for better control measures in seafood production to ensure public health safety.

Immunocompromised individuals are at greater risk when consuming raw fish and shellfish or when open wounds are exposed to contaminated marine environments. The emergence of antibiotic-resistant bacteria has raised concerns over public health and animal health globally. Infections involving resistant hemolytic bacteria can be life-threatening due to limited treatment options. This study aimed to evaluate the resistance profiles of hemolytic Shewanella species against 21 antibiotics commonly used to treat Gram-negative bacterial infections. A total of 166 hemolytic isolates recovered from oyster (n = 107) and seawater (n = 59) samples obtained from the Mid-Atlantic sampling sites between 2019 and 2021 were tested using Sensititre GNX2F antimicrobial susceptibility plates. Overall, 16.27% of oyster isolates and 18.94% of seawater isolates were resistant to one or more antibiotics. Only Ertapenem showed a statistically significant difference in resistance between alpha and beta hemolytic groups. Resistance levels varied across species. Shewanella algae and S. khirikhana exhibited the highest resistance to 10 and 14 antibiotics, respectively, followed by S. marisflavi (11 antibiotics) and S. indica (9 antibiotics). Doxycycline, Levofloxacin, Minocycline, and Tigecycline were the most effective antibiotics, with low or no resistance observed among Shewanella isolates from both seawater and oysters. This is the first study to provide detailed insights into the antibiotic resistance profiles of hemolytic Shewanella species in the Chesapeake Bay and the Maryland Coastal Bays.

However, fire impacts on catchment hydrology are often neglected from land surface model (LSM) simulations. Western U.S. wildfire activity has been increasing in recent decades and is projected to continue increasing over at least the next three decades, and thus it is important to evaluate if neglecting fire impacts in operational land surface models (LSMs) is a significant error source that has a noticeable signal among other sources of uncertainty. We evaluate a widely used state‐of‐the‐art LSM (Noah‐MP) in runoff and snowpack simulations at two representative fire‐affected snow‐dominated catchments in the Pacific Northwest: Andrew's Creek in Washington and Johnson Creek in Idaho. These two catchments are selected across all western U.S. fire‐affected catchments because they are snow‐dominated and experienced more than 50% burning in a single fire event with minimal burning outside of this event, which allows analyses of distinct pre‐ and post‐fire periods. There are statistically significant shifts in model skills from pre‐to post‐fire years in simulating runoff and snowpack. At both study catchments, simulations miss enhancements in early‐spring runoff and annual runoff efficiency during post‐fire years, resulting in persistent underestimates of annual runoff anomalies throughout the 12‐year post‐fire analysis periods. Enhanced post‐fire snow accumulation and melt contributes to observed but unmodeled increases of spring runoff and annual runoff efficiency at these catchments. Informing simulations with satellite observed land cover classifications, leaf area index, and green fraction do not consistently improve the model ability to simulate hydrologic responses to fire disturbances.

This study quantified responses from the Weather Research and Forecasting Hydrological modelling system (WRF‐Hydro) to a suite of fire‐related perturbations to hydrologic soil and runoff parameters, vegetation area, land cover classifications and associated vegetation properties, and snow albedo across the heavily burned Feather River Basin in California. These experiments were used to quantify the impacts of fire‐related perturbations in model simulations under the observed meteorological conditions during the 2000–2022 water years and determine whether applying these fire‐related perturbations enhanced post‐fire model accuracy across the 11–12 post‐fire months evaluated herein. The most comprehensive fire‐aware simulation consistently modelled enhanced annual catchment streamflow (by 8%–37%), subsurface flow (by 72%–116%), and soil moisture (by 4%–9%), relative to the baseline simulation which neglected fire impacts. Simulated fire‐enhanced streamflow was predominately attributable to fire‐induced vegetation area reductions that reduced transpiration. Simulated streamflow enhancements occurred throughout the water year, excluding early‐summer (e.g., May–June) when the baseline simulation modelled relatively more snowmelt and streamflow because fire perturbations caused earlier model snow depletion. Vegetation area reductions favoured increased model ground snow accumulation and enhanced snow ablation while imposed snow albedo darkening enhanced ablation, ultimately resulting in similar peak SWE and earlier snow disappearance (on average by 8‐days) from the most comprehensive fire‐aware simulation relative to the baseline simulation. The baseline simulation had large degradations in streamflow accuracy following major fire events that were likely partially attributable to neglecting fire disturbances. Applying fire‐related perturbations reduced post‐fire streamflow anomaly biases across the three study catchments. However, remaining large post‐fire streamflow uncertainties in the fire‐perturbed simulation underscores the importance of additional observationally constrained fire‐disturbance model developments.

Suction cup tags deployed for behavioral studies of free-ranging whales sometimes retain exfoliated epidermal tissue from the tagged animal that can potentially be used for molecular genetic sexing. This study provides a protocol to recover and preserve skin from suction cup tags and compares the accuracy of resulting PCR-based sex determinations relative to independent data on individual sex. Skin samples (N = 43) were recovered from tags deployed on North Atlantic humpback and right whales of known sex. Of these, data were obtained from 21 tags deployed on 15 individuals. A PCR-based sex determination yielded correct results for 9 male and 11 female samples. One female was misidentified as male in one of two samples collected from the same tag, suggesting the potential for sexing error based on suction cup tag-derived tissue. The probability of accurate results given current information was estimated using Bayes theorem, with a female result estimated to be 100% reliable, and a male result estimated to be 91% reliable. The minimum DNA yield that resulted in a successful PCR run was 29 ng, however four samples with higher DNA yield did not. With further work, this protocol may increase the reliable data that can be collected as part of suction-cup tagging studies of cetaceans.

AB - On tropical reefs, environmental conditions and biological interactions are fundamental drivers of the spatial distribution of corals, which in turn influences community attributes and ecosystem rate processes. Here we focus on a major habitat-providing species of coral, the thicket-forming staghorn Acropora pulchra, in Moorea, French Polynesia, to explore environmental attributes that shape its local distribution. At the island scale, A. pulchra decreased in abundance with increasing distance from the shoreline and was inversely related to nitrogen enrichment. To investigate growth-predation risk tradeoffs, we quantified growth and corallivory rates across major abiotic (nutrients, sedimentation) and biotic (corallivorous fish biomass) gradients. At 20 sites divided between fringing reef and mid-lagoon habitats, we quantified colony growth of transplanted A. pulchra fragments (nubbins) that were either exposed or protected from predators after 83 days. Nubbins protected from corallivores grew more in the mid-lagoon than on the fringing reef, whereas mid-lagoon nubbins exposed to predators only achieved 30% of the growth of exposed fringing reef nubbins. These findings suggest that a growth-predation risk tradeoff exists for A. pulchra, with predation a major constraint on the local distribution of A. pulchra thickets that hinders the ability of staghorn to proliferate further offshore from the fringing reef.

An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral (Acropora palmata) and staghorn coral (Acropora cervicornis), were severely affected. These species have been the primary focus of reef restoration in Florida for decades. ...

AB - An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral (Acropora palmata) and staghorn coral (Acropora cervicornis), were severely affected. These species have been the primary focus of reef restoration in Florida for decades. Substantial losses of these species occurred in outplanted populations, in ocean-based nurseries, and among remnant wild colonies, leading to uncertainty over their future in the Florida Keys, given recent observed trends in climate conditions. However, the past 2 decades of restoration activity created a community of experts, a network of ocean-based and land-based coral-rearing infrastructure, and 2 independent land-based coral gene banks that prevented regional extirpation and preserved much of the genetic richness of these critically endangered coral species. Without the past decades of effort and the emergency response associated with the 2023 bleaching event, Florida acroporids would largely have been lost. This outcome afforded by the restoration network in Florida demonstrates the value of proactively establishing resources prior to major disturbances. We identified several critical strategies that, in the context of existing climate change, are preventing the extirpation of coral species in Florida, including extending collaborative restoration efforts to solidify a network of trained experts; establishing trust-focused relationships among management agencies and restoration groups; testing direct interventions to reduce light and temperature stress early during thermal anomalies; developing redundant ocean-based and land-based nurseries; and establishing living coral gene banks prior to major threats to prevent the extirpation of coral species.
