Limnology and Oceanography: Methods, EarlyView.Abstract Acoustic cameras, or imaging sonars, are often used to monitor marine energy sites in regions where the water is too dark or turbid for optical sensing. To do so more effectively, scientists are investigating automated detection methodologies to use on these data.

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.

Freezing and chemical preservatives alter the stable isotope values of carbon and nitrogen of the Asiatic clam (Corbicula fluminea) [PDF]
, 2011 We tested the impacts of most common sample preservation methods used for aquatic sample materials on the stable isotope ratios of carbon and nitrogen in clams, a typical baseline indicator organism for many aquatic food web studies utilising stable ...

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

Association between periphyton and bioflocs systems in intensive culture of juvenile Nile tilapia
Acta Scientiarum: Animal Sciences, 2016 The present work aimed at determining the effects of the association between the periphyton-based system with the bioflocs-based system in the intensive culture of juvenile Nile tilapia (1.56 ± 0.07 g; 72 fish m-3), on variables of water quality, growth ...

Limnology and Oceanography: Methods, EarlyView.Abstract Accurate quantification of particulate phosphorus is critical for understanding biogeochemical processes in aquatic systems. Extra high‐temperature dry combustion at 800°C improves phosphorus recovery by ~ 11% compared to lower‐temperature methods.
