Chlorophyll-a concentrations in the Arabian Gulf waters of arid region: A case study from the northern coast of Qatar
( Elsevier , 2022 , Article)Remote sensing of spectrally active Chlorophyll-a (Chl-a) in the gulf water of an arid region is important to understand the spatial and temporal variations of phytoplankton and biomass in the water. This study characterizes ... -
Editorial: Challenges in characterizing nano- to macro-plastics and adhered substances in the aquatic environment
( Frontiers Media , 2022 , Article)Globally, plastic contamination is one of the serious planetary threats, affecting almost all environmental matrices such as air, water, soil, sediment, and biota (including humans). It is estimated that ∼19 to 23 million ... -
Aquaculture sediments amended with biochar improved soil health and plant growth in a degraded soil
( Elsevier , 2023 , Article)Sustainable and safe management of aquaculture sediments is of great concern. Biochar (BC) and fishpond sediments (FPS) are rich in organic carbon and nutrients and thus can be used as soil amendments; however, it is not ... -
Photodegradation and Its Effect on Plant Litter Decomposition in Terrestrial Ecosystems: A Systematic Review
( MDPI , 2023 , Article Review)Photodegradation is an important mechanism that affects carbon and nutrient cycling; a significant amount of data has been reported previously. The present review includes the effect of a wider spectrum of solar radiation ... -
