We ain’t afraid of no ghosts: Tracking habitat interactions and movement dynamics of ghost PIT tags under differing flow conditions in a sand bed river
J. Benjamin Stout, Mary Conner, Phaedra E. Budy, Peter Mackinnon, Mark McKinstry
2019, North American Journal of Fisheries Management (39) 1337-1347
The use of PIT tags has rapidly proliferated since their introduction, and new mobile detection methods have been developed. However, the presence of ghost tags (i.e., PIT tags left in the system after a fish dies) creates uncertainty about the status (live or dead) of tags...

The data show a strong underlying spatial component and somewhat weaker temporal component. Drivers of the spatial component are favorable...
Where’s the rock: Using convolutional neural networks to improve land cover classification
Helen Petlyak, Corina Cerovski-Darriau, Vadim Zaliva, Jonathan D. Stock
2019, Remote Sensing (11)
While machine learning techniques have been increasingly applied to land cover classification problems, these techniques have not focused on separating exposed bare rock from soil covered areas. Therefore, we built a convolutional neural network (CNN) to differentiate exposed bare rock (rock) from soil cover (other). We made a...

Empirical estimation of natural geoelectric hazards
Jeffrey J. Love, Paul A. Bedrosian, Anna Kelbert, Greg M. Lucas
2019, Book chapter, Geomagnetically induced currents from the sun to the power grid
Geoelectric field time series can be estimated by convolving estimates of Earth‐surface impedance, such as those obtained from magnetotelluric survey measurements, with historical records of geomagnetic variation obtained at magnetic observatories. This straightforward procedure permits the mapping of geoelectric field variation during magnetic storms. Statistical analysis of the time series...
