Ammonium plays an important role in the nitrogen cycle in marine environments. There is no
universal method for ammonium analysis that can be applied to all types of seawater and …

In order to advance our comprehension of the underlying regulatory mechanisms governing
nitrogen processes in aquatic ecosystems, it is crucial to understand the roles of ammonium …

In this study, the ligand functionalized nano-conjugate material was developed for the
sensitive and selective detection and removal of toxic arsenic (V) and phosphate ions in …

The Coastal Observing System for Northern and Arctic Seas (COSYNA) was established in
order to better understand the complex interdisciplinary processes of northern seas and the …

Ammonia is an important nutrient in coastal and oceanic waters due to its role in the aquatic
nitrogen cycle. However, the presence of the analyte at trace concentrations (nanomolar) …

High-frequency field nutrient analyzers offer a promising technology to solve time-
consuming and laborious sampling problems in dynamic and complex river–estuarine …

Abstract Nutrients (phosphate, nitrate, nitrite, ammonium and silicate) exert strong controls
on oceanic primary productivity. In oligotrophic areas, which cover approximately 40% of the …

Autonomous sensors are required for a comprehensive documentation of the changes in the
marine carbon system and thus to differentiate between its natural variability and …

A simple environmentally-friendly ammonia (SEA) analyser based on programmable flow
was developed for the determination of trace levels of ammonia nitrogen in marine waters …

Herein, a novel homemade portable fluorescence detector that is simple, smaller, and
transportable for the shipboard analysis of ammonium in estuarine and coastal waters has …
