Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

Limnology and Oceanography: Methods, EarlyView.
Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

Methodological constraints for the stable isotope analysis of different tissues: A comparison between muscle and whole‐body samples in freshwater gammarids

Limnology and Oceanography: Methods, EarlyView.
Abstract Carbon (δ13C) and nitrogen (δ15N) stable isotope ratios allow the reconstruction of food webs, provided that all trophic levels are properly characterized. In freshwater ecosystems, small‐bodied invertebrates often occupy central positions in food webs, with whole‐body samples commonly used for their stable isotope analysis, due to ...

A novel approach to estimate non‐algal particle absorption for improved retrieval of pigment concentrations in coastal waters

Limnology and Oceanography: Methods, EarlyView.
Abstract Phytoplankton play a central role in ocean biogeochemistry and understanding their composition and variability is critical for monitoring marine ecosystem dynamics. Continuous spectrophotometric measurements (using a Seabird Sci. AC‐S) along ship tracks enable high‐resolution measurements of particle spectral absorption (apλ$$ {a}_p\left ...

Sodium sulfite can reliably induce chemical hypoxia without toxic effects in the model sea anemone species, Exaiptasia diaphana

Limnology and Oceanography: Methods, EarlyView.
Abstract Climate change is accelerating the deoxygenation of aquatic ecosystems, so understanding its effects on biological processes is increasingly critical. An emerging method for inducing hypoxia during experimentation utilizes sodium sulfite (SSI) to scavenge oxygen; however, it remains unclear if hypoxia‐inducing concentrations of SSI are toxic ...

Evaluation of methods for the analysis of oxygen and carbon dioxide in water, sediment, litter, and soil

Limnology and Oceanography: Methods, EarlyView.
Abstract Choosing an appropriate analyzer to measure concentrations of oxygen (O2) and carbon dioxide (CO2) during biogeochemical cycling studies can be difficult, considering the range of options available. While several studies examine the abilities of specific analyzers, comparison of multiple analyzers and environmental sample types is lacking.
