UCanWBGT: urban street canyon heat stress calculation for weather and climate models

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This work introduces UCanWBGT, a new model to calculate wet‐bulb globe temperature in an urban environment, suitable for use with weather and climate model data. We present the model, then verify its performance against observations made in the streets of Paris during heatwave conditions.

DuckNet: an open‐source deep learning tool for waterfowl species identification in UAV imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Using drones with thermal‐RGB sensors and a deep learning model (RetinaNet with ResNet‐50), we surveyed non‐breeding waterfowl across restored wetlands in the Mississippi Alluvial Valley. Our model, DuckNet, achieved high accuracy and offers an open‐source, customizable tool for automated waterfowl detection to support conservation monitoring ...

Detection of large acoustic energy flux in the solar atmosphere

open access: yes, 2010
We study the energy flux carried by acoustic waves excited by convective motions at sub-photospheric levels. The analysis of high-resolution spectropolarimetric data taken with IMaX/Sunrise provides a total energy flux of ~ 6400--7700 Wm$^{-2}$ at a ...

Impact of parameterization in multiple acoustic index comparisons: practical cases in terrestrial and underwater soundscapes

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Parameter choices in acoustic analyses (sampling frequency, FFT size and window overlap) strongly influence multivariate soundscape separation. Using terrestrial and coral reef recordings, we show that these settings can exaggerate or mask ecological differences, emphasizing the need for parameter sensitivity testing and transparent reporting in ...

Cameras do not always take a full picture: wolf activity patterns revealed by accelerometers versus road‐positioned camera traps

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Camera traps have become an increasingly popular non‐invasive alternative to animal‐attached devices for studying wildlife behaviour. This study compared wolf (Canis lupus) activity patterns derived from collar accelerometers and road‐positioned camera traps and revealed strong overall agreement but also important seasonal and diel mismatches between ...

Dispersive Calculation of the Massless Multi-loop Sunrise Diagram [PDF]

open access: yes, 2018
The massless sunrise diagram with an arbitrary number of loops is calculated in a simple but formal manner. The result is then verified by rigorous mathematical treatment. Pitfalls in the calculation with distributions are highlighted and explained.

From snapshots to continuous estimates: Augmenting citizen science with computer vision for fish monitoring

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study presents an end‐to‐end computer‐vision pipeline for monitoring fish migration using underwater video. We integrate field camera deployment, annotation, model training and automated in‐season counting to generate continuous, high‐resolution data on river herring spawning migration.

Biological production in the Eastern Pacific Ocean [PDF]

open access: yes, 1964
ENGLISH:The present paper is principally concerned with the geographic distribution of the standing crop and production of phytoplankton at the surface of the eastern Pacific, east of 130°W and between 10°N and 33°S, as reflected by recently collected ...
