Water Quality Analysis and Chl- Prediction of 15 Large-scale Freshwater Lakes in Korea by Multivariate Statistical Analysis [PDF]

open access: yes대한환경공학회지, 2022
Objectives A large-scale freshwater lake is a freshwater lake with a storage of 5,000,000 tons or more among freshwater lakes. It is located at the end of the basin, so complex and various pollutants flow in from a wide basin, and it has a characteristic

Subcellular view of host–microbiome nutrient exchange in sponges: insights into the ecological success of an early metazoan–microbe symbiosis

open access: yesMicrobiome, 2021
Background Sponges are increasingly recognised as key ecosystem engineers in many aquatic habitats. They play an important role in nutrient cycling due to their unrivalled capacity for processing both dissolved and particulate organic matter (DOM and POM)

Upscaling Tracer‐Aided Ecohydrological Modeling to Larger Catchments: Implications for Process Representation and Heterogeneity in Landscape Organization

open access: yesWater Resources Research, 2023
Stable isotopes of water are ideal tracers to integrate into process‐based models, advancing ecohydrological understanding. Current tracer‐aided ecohydrological modeling is mostly conducted in relatively small‐scale catchments, due to limited tracer data

Periphyton in urban freshwater facilitates transformation of trace organic compounds: A case study on iodinated contrast media

open access: yesFrontiers in Environmental Science, 2023
Introduction: Due to urbanization and demographic change trace organic compounds (TrOCs), synthetic chemicals such as pharmaceuticals, personal care products or biocides are an increasing problem in waterbodies affected by treated sewage.

Intermittent meromixis controls the trophic state of warming deep lakes

open access: yesScientific Reports, 2020
Vertical mixing modulates nutrient dynamics in lakes. However, surface warming reduces the range of vertical mixing and the probability of full circulation events. Important consequences of reduced vertical mixing include the sequestration of phosphorus (
