Immediate and cumulative effects of nutrient and extreme weather disturbances on pond greenhouse gas emissions

Tyler J. Butts, Ellen A. Albright, Steven J. Hall, Jonathan A. Walter et autres

Abstract Ponds are significant emitters of greenhouse gases (GHGs). While eutrophication stimulates GHG emissions, responses to nutrient pulses and weather events are less clear. We investigated both immediate and cumulative effects of experimental storm‐scale nutrient pulses, along with unplanned extreme heat and …

Summer water chemistry, high frequency sensors, zooplankton and benthic macroinvertebrate community composition, periphyton, fish, and macrophyte biomass, along with lake metabolism and greenhouse gas dynamics in six experimental ponds in central Iowa, USA (2020)

Tyler J. Butts, Ellen A. Albright, Quin K Shingai, Robert A Johnson et autres

This data product contains physical, chemical, and biological data ranging from the minute to daily to weekly scale in six artificial ponds (400 square meter surface area, 2m depth) in central Iowa (USA) 2020. Ponds were paired into three sets of treatment …

Modular Compositional Learning Improves 1D Hydrodynamic Lake Model Performance by Merging Process‐Based Modeling With Deep Learning

Robert Ladwig, Adrian N. Daw, Ellen A. Albright, Cal D. Buelo et autres

Abstract Hybrid Knowledge‐Guided Machine Learning (KGML) models, which are deep learning models that utilize scientific theory and process‐based model simulations, have shown improved performance over their process‐based counterparts for the simulation of water temperature and hydrodynamics. We highlight the modular compositional learning …

The influence of carbon cycling on oxygen depletion in north-temperate lakes

Austin D. Delany, Robert Ladwig, Cal D. Buelo, Ellen A. Albright et autres

Abstract. Hypolimnetic oxygen depletion during summer stratification in lakes can lead to hypoxic and anoxic conditions. Hypolimnetic anoxia is a water quality issue with many consequences, including reduced habitat for cold-water fish species, reduced quality of drinking water, and increased nutrient and …

Legacy Phosphorus and Ecosystem Memory Control Future Water Quality in a Eutrophic Lake

Paul C. Hanson, Robert Ladwig, Cal D. Buelo, Ellen A. Albright et autres

Abstract Lake water clarity, phytoplankton biomass, and hypolimnetic oxygen concentration are metrics of water quality that are highly degraded in eutrophic systems. Eutrophication is linked to legacy nutrients stored in catchment soils and in lake sediments. Long lags in water quality improvement …

Modular compositional learning improves 1D hydrodynamic lake model performance by merging process-based modeling with deep learning

Robert Ladwig, Arka Daw, Ellen A. Albright, Cal D. Buelo et autres

Key Points:• Deep learning models were pretrained on process-based lake water temperature model output and fine-tuned on observed high-frequency data.• Fine-tuned deep learning model was integrated into process-based model creating the hybrid model.• Hybrid model outperformed process-based model and two alternative deep …
