Are Harmful Algal Blooms Increasing in the Great Lakes?

Karl R. Bosse, Gary L. Fahnenstiel, Cal D. Buelo, Matthew B. Pawlowski et autres

This study used satellite remote sensing to investigate trends in harmful algal blooms (HABs) over the last 21 years, focusing on four regions within the Laurentian Great Lakes: western Lake Erie, Green Bay, Saginaw Bay, and western Lake Superior. HABs in the …

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

Robert Ladwig, Adrian Daw, Ellen 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 Delany, Robert Ladwig, Cal D. Buelo, Ellen 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 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 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 …

Increasing heatwave frequency in streams and rivers of the United States

Spencer J. Tassone, Alice F. Besterman, Cal D. Buelo, D. T. Ha et autres

Abstract Heatwaves are increasing in frequency, duration, and intensity in ocean, coastal, and lake ecosystems. While positive water temperature trends have been documented in many rivers, heatwaves have not been analyzed. This study examined heatwaves in rivers throughout the United States between …
