2021, Integrated Environmental Assessment and Management (18) 245-257
A comparison of the presence of additives in airport deicers commonly used in the United States and in airport runoff was conducted with data collected before and after changes in deicer formulations. Three isomers of benzotriazoles (BTs)—4-methyl-1H-benzotriazole (4-MeBT), 5-methyl-1H-benzotriazole (5-MeBT), and 1H-benzotriazole (1H-BT)—are corrosion inhibitors added to some formulations of...

A review of factors affecting PIT tag detection using mobile arrays and use of mobile antennas to detect PIT-tagged suckers in a wadeable Ozark stream
Douglas L. Zentner, Skylar Wolf, Shannon K. Brewer, Daniel E. Shoup
2021, North American Journal of Fisheries Management (41) 697-710
Advantages of passive integrated transponder (PIT) tags are their small size, longevity, and low-cost compared to other tags. PIT tags are often used in fisheries to study movement patterns, survival, or estimate population size. However, PIT tags are limited by their short detection distance. Mobile PIT antennas may increase the...

James A. Luoma, Nicholas Robertson, Justin R. Schueller, Nicholas Schloesser, Todd Johnson, Todd J. Severson, Matthew J Meulemans, Erica Muelemans
2021, Report
A solid lampricide formulation containing 23% 3-trifluoromethyl-4-nitrophenol (TFM) as the active ingredient was developed in the mid-1980s for use in small tributaries of dendritic streams during routine treatments to kill larval sea lamprey. This TFM bar formulation was designed to use a matrix of commercially prepared surfactants that would dissolve...

Carl J. Legleiter, Paul J. Kinzel
2021, Frontiers in Water (3)
Conventional, field-based streamflow monitoring in remote, inaccessible locations such as Alaska poses logistical challenges. Safety concerns, financial considerations, and a desire to expand water-observing networks make remote sensing an appealing alternative means of collecting hydrologic data. In an ongoing effort to develop non-contact methods for measuring river discharge, we evaluated...

Dry formation of recent Martian slope features
Colin M. Dundas
2021, Book chapter, Mars Geological Enigmas From the Late Noachian Epoch to the Present Day
Martian surface conditions are cold and dry, unfavorable for liquid water, yet steep slopes display young and currently active features suggestive of wet processes. These include recurring slope lineae and slope streaks, gully landforms, and small lobate features. Wet origins for these...
Amplified impact of climate change on fine-sediment delivery to a subsiding coast, Humboldt Bay, California
Jennifer Curtis, Lorraine E. Flint, Michelle A. Stern, Jack Lewis, Randy D. Klein
2021, Estuaries and Coasts (44) 2173-2193
In Humboldt Bay, tectonic subsidence exacerbates sea-level rise (SLR). To build surface elevations and to keep pace with SLR, the sediment demand created by subsidence and SLR must be balanced by an adequate sediment supply. This study used an ensemble of plausible future scenarios to predict potential climate change impacts...
Use of the smeltCam as an efficient fish sampling alternative within the San Francisco Estuary
Brock Huntsman, Frederick V. Feyrer, Matthew J. Young
2021, San Francisco Estuary and Watershed Science (19)
Resource managers often rely on long-term monitoring surveys to detect trends in biological data. However, no survey gear is 100% efficient, and many sources of bias can be responsible for detecting or not detecting biological trends. The SmeltCam is an imaging apparatus developed as a potential sampling alternative to long-term...

Long-term shedding from fully convalesced individuals indicates that Pacific herring are a reservoir for viral hemorrhagic septicemia virus
Paul Hershberger, Ashley MacKenzie, Jacob L. Gregg, M. D. Wilmot, Rachel L. Powers, Maureen K. Purcell
2021, Diseases of Aquatic Organisms (144) 245-252
Processes that allow viral hemorrhagic septicemia (VHS) virus to persist in the marine environment remain enigmatic, owing largely to the presence of covert and cryptic infections in marine fishes during typical sub-epizootic periods. As such, marine host reservoirs for VHS virus have not been fully demonstrated, nor have the mechanism(s)...
