What is “accuracy”? Rethinking machine learning classifier performance metrics for highly imbalanced, high variance, zero‐inflated species count data

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Machine learning has opened the door for the automated sorting (classification) of images, holograms and acoustic backscatters of individual plankton, invertebrates, fish and marine mammals. However, this field is complicated by decades of paradoxically promising reports of classifier performance that do not correlate with real‐world uptake of

Relationships between acoustic scattering layers and ocean stratification: An acoustic approach to estimate mixed layer depth

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Ocean stratification, measured as mixed layer depth (MLD), is an important feature that influences many processes in the ocean; for example, by mediating the fluxes of momentum, heat and crucially key gases such as CO2 and oxygen from the atmosphere into the water column and vice versa. The conventional methods to measure stratification (e.g.,

A low‐cost, automated, and adaptable system for field‐based measurement of pCO2, pCH4, and associated variables in groundwater

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The Groundwater Automated Chemical Examiner (GrACE) is an automated analytical system of integrated sensors for the field‐based measurement of chemical and physical properties of groundwater. The GrACE system was designed to explore parameters influencing the dissolved concentrations of carbon dioxide (pCO2) and methane (pCH4) in groundwater ...

The IceShark, an effective method for sampling plankton under sea ice

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Seasonal sea ice plays a crucial role in shaping coastal ecosystem dynamics throughout the circumpolar region. Of particular interest to oceanographers is the ice‐ocean interface which functions as a multidimensional habitat, supporting both sympagic algae and pelagic phytoplankton in the under‐ice surface waters.

Glide-snow avalanche characteristics at different timescales extracted from time-lapse photography

open access: yesAnnals of Glaciology
Glide-snow avalanches release due to a loss of friction at the snow–ground interface, which can result in large avalanches that endanger infrastructure in alpine regions.

Navigating and reframing tensions within equity‐centered learning health systems

open access: yesLearning Health Systems, EarlyView.
Abstract Introduction Canada recently joined a growing list of countries that are establishing national collaboratives to exchange knowledge on and scale learning health systems (LHSs) across geographies and sectors. The first symposium of the pan‐Canadian Learning Health Hub was held in June 2024 and included a keynote presentation and breakout ...

Applications of a Novel Wireless System for Real‐Time Atmospheric Corrosion Monitoring

open access: yesMaterials and Corrosion, EarlyView.
Developed monitoring system is a powerful tool for real‐time atmospheric corrosion monitoring. Humidity plays a critical role in the corrosion process. Limiting environmental parameters inducing maximum corrosion vary depending on the pollutants present. A monitoring system can be used in a wide range of scientific and practical applications.
