Impact of an Environmental Index of Recruitment on the Stock Assessment for Petrale Sole ( Eopsetta jordani Lockington, 1878) in the California Current Ecosystem

ABSTRACT Stock assessments provide key scientific input for managing fisheries. Age‐structure information is important for these assessments because it provides the foundation for estimating recruitment, which impacts estimates of future spawning biomass and other assessment para...

The MISR Research Product Algorithm – producing global, self-consistent, pixel-level aerosol retrievals for the Multi-angle Imaging SpectroRadiometer

Abstract. The MISR Research Aerosol retrieval algorithm (RA) was developed in parallel with the MISR standard operational algorithm (SA), to explore innovative retrieval ideas for possible implementation in the SA, and to provide higher-spatial-resolution results with enhanced se...

The HRRR Meteorology, Energy, and Transmission (MET) Toolkit: advancing high-resolution atmospheric data for contiguous US energy applications

Abstract. High-quality, multiyear atmospheric data are foundational for power system planning and grid integration. While the legacy Wind Integration National Dataset (WIND) Toolkit has long served as the industry standard, its historical record ends in 2013, leaving a critical g...

Quantifying exposure and residence time of migrating Atlantic salmon post-smolts at aquaculture sites in a region of extreme tides

Aquaculture production now exceeds capture fisheries, but concerns persist regarding environmental impacts. Salmon farms within Atlantic salmon (Salmo salar) migratory corridors may create hotspots of predation, parasites, or disease that could affect out-migrating post-smolts. H...

Observational Validation of Boundary‐Layer Cloud Regimes in Arctic Cold Air Outbreaks

Abstract Arctic cold air outbreaks (CAOs) produce low‐level cloud patterns influencing the surface radiative balance. The stability parameter (boundary‐layer height over Monin‐Obukhov length) is theorized to distinguish shear‐driven roll convection from buoyancy‐driven cellular c...

Physiological responses of Atlantic surfclams (Spisula solidissima) to moderate ocean acidification across thermal regimes

Understanding marine organismal responses to co-occurring climate stressors is critical for predicting changes in ecosystems and commercial fisheries. The Atlantic surfclam supports a major commercial fishery in the Northeastern United States, where ocean warming and acidificatio...

Constraints on the Loss of Hydroperoxymethyl Thioformate (HPMTF) to Marine Clouds Using Aircraft Observations

Abstract The photochemical oxidation of dimethyl sulfide (DMS) by the hydroxyl radical (OH) contributes to the production and growth of particles and cloud condensation nuclei in the marine boundary layer (MBL). DMS oxidized by OH can go on to form a stable intermediate, hydroper...

Global Distribution of Freshwater Paralytic Shellfish Poisoning Toxins (“Saxitoxins”) 1967–2025: Implications, Limitations, and Application to Risk Assessment

Abstract Paralytic shellfish poisoning (PSP) toxins (PSPTs) (“Saxitoxins”) are a class of neurotoxins identified globally in freshwater and marine systems but are understudied in freshwater environments. We collected literature reports of PSPTs in natural systems from their first...

A unifying theory for the evaluation of conditional Akaike information for mixed-effects models

{Simulation studies are conducted to assess the accuracy of our method for evaluating the conditional AIC and its model selection performance across a wide range of mixed-effects models. The proposed approach provides a valuable tool for model selection in the context of mixed-ef...

Dependence of Hurricane Track Forecasts on the Spectral Representation of Cumulus Convection

This study investigates the sensitivity of hurricane track and intensity forecasts to various cumulus parameterization schemes with scale-awareness, including the Simplified Arakawa-Schubert (SAS), Relaxed Arakawa-Schubert (RAS), and Chikira-Sugiyama Arakawa-Wu (CSAW), within the...

Population-level impacts of reducing artificial light at night across an entire migratory corridor

Artificial light at night (ALAN) is a widespread anthropogenic pollution that poses challenges for wildlife in nearly every ecosystem on planet Earth. Although there has been substantial progress on understanding the effects of ALAN on animal physiology and behaviour, few studies...

Resolving Convective‐Scale Cloud and Precipitation Structures in Tropical Cyclone Rainbands With Novel Raman Lidar Observations

Abstract Low‐level clouds in the tropical cyclone (TC) rainbands modulate the radial inflow of warm, moist boundary layer air, which can impact TC intensity. Yet, precisely measuring rainband cloud boundaries with existing remote sensing techniques remains a challenge. To address...

Microsynteny Analysis Clarifies the Early Diversification of Cypriniform Fishes

While genomic data are powerfully informative for phylogenetic inference, traditional sequence-based analyses can be confounded by issues like homoplasy and incomplete lineage sorting, leaving deep nodes unresolved. Synteny, the conservation of gene order along a chromosome, pres...

Wind‐Driven Circulation Feedbacks Offset Tropical Geoengineered Sea Salt Emissions

Abstract Using a NOAA Geophysical Fluid Dynamics Laboratory coupled atmosphere–ocean (CM4) comprehensive model, we employ simulations of enhanced, geoengineered sea salt aerosol (SSA) emissions in the tropics to examine the circulation response to idealized marine cloud brighteni...

Will work for sardines: 20 years of animal-borne ocean observing by Australia’s Integrated Marine Observing System (IMOS) Animal Tagging Facility

The world’s ocean stores ~90% of the excess heat generated by anthropogenic global warming, making sustained ocean observations essential for understanding physical, biological and climate processes. Here, we describe how the Integrated Marine Observing System (IMOS) Animal Taggi...

Evaluation of the Impact of Aged Biomass Burning Emissions on the Global Ozone From the Surface to the Lower Stratosphere

Abstract Biomass burning (BB) is a major global sources of ozone (O 3 ) precursors, including nitrogen oxides (NO x ), carbon monoxide (CO), and volatile organic compounds (VOCs). Here, we combine Community Earth System Model 1 with airborne measurements from the NASA Atmospheric...

Method for Calculating a Generic Oil

Accidental oil spills are an all-too-common occurrence. In order to properly plan for and respond to oil spills, responders and planners need to understand how the oil will behave in the environment: how it will weather and how it will affect ecosystems and biota. To address this...

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food...

Layer‐Dependent Diurnal Moist Static Energy Biases in the Unified Forecast System During the MJO Preconditioning Stage: A DYNAMO Case Study

Abstract Accurate simulation of the Madden‐Julian Oscillation (MJO) requires realistic diurnal evolution and vertical distribution of moist static energy (MSE). While prior studies documented MSE bias in simulations, vertically dependent physical processes responsible for these b...
