What Do Latest CMIP6 Global Climate Models Say About Future Arctic Sea Ice Coverage Changes?
International Journal of Climatology, EarlyView.Modelling of sea ice dynamics has significantly improved between CMIP5 and CMIP6, with nearly three times as many models capturing realistic annual variability in sea ice extent (SIE). What we previously thought was a non‐linear pattern of low SIE observations in 2007–2010 that would continue throughout time now appears to be non‐record‐setting lows in

A Nonlinear Quantitative Model for Measuring Concentration Ratios From Raman Intensities
Journal of Raman Spectroscopy, EarlyView.Estimating concentration from Raman intensity ratios is complicated by cross‐contributions from overlapping peaks, causing measured ratios to deviate from the linear behavior assumed in conventional quantitative models. This nonlinear method fully accounts for cross‐contributions, allowing estimation of concentration over several orders of magnitude ...

Sediment trap preservative choice impacts particle‐associated microbial community composition
Limnology and Oceanography: Methods, EarlyView.Abstract Understanding and quantifying the microbial contribution to particulate organic matter (POM) flux and carbon cycling in the ocean relies largely on the collection of sinking POM. A critical aspect of evaluating microbial communities on sediment trap‐collected POM is their preservation until recovery and sample processing.

Limnology and Oceanography: Methods, EarlyView.Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Understanding the dynamic behavior of structural components is crucial for optimizing performance and ensuring structural integrity. This study presents a new method that combines a systematic experimental investigation of four distinct hole geometries (circular, square, compact rectangular, and long rectangular) with varying hole counts, all ...
