2022, Oil & Gas Journal (120) 46-53
The revision of federal safety regulations for integrity management of gas transmission pipelines to require explicit consideration of seismicity increases the importance for operators to be actively identifying high-consequence areas (HCAs), evaluating seismic-related threats, and choosing a risk model to support risk management decisions. To ensure equal access to information...

M.A. Kaemingk, R. Arlinghaus, M.H. Birdsong, C.J. Chizinski, R. Lyach, K.L. Wilson, Kevin L. Pope
2022, Fisheries Research (254)
The size of an ecosystem affects ecological interactions, but less is known about how ecosystem size may affect social interactions. We posit that ecosystem size could serve as a basis for understanding and contextualizing social interactions, connecting how ecosystem size influences natural resource investment decisions and the use of ecosystem services. We...

2022, Report
Lake wide acoustic (AC) and bottom trawl (BT) surveys are conducted annually to generate indices of pelagic and benthic prey fish densities in Lake Michigan. The BT survey has been conducted each fall since 1973 using 12-m trawls at depths ranging from 9 to 110 m and includes 70 fixed...
Interagency Flood Risk Management (InFRM) watershed hydrology assessment for the Neches River basin. Appendix A: Statistical hydrology
David S. Wallace
2022, Report
Statistical analysis of the observational record from U.S. Geological Survey (USGS) streamgaging stations and other historical information provides an informative means of estimating flood flow frequency. Flood flow frequency is defined by values or quantiles of discharge for selected annual exceedance probabilities (AEPs) (England and others, 2018). The annual peak...
Response in the water level of Anvil Lake, Wisconsin, to changes in meteorological and climatic changes, Wisconsin
Dale M. Robertson
2022, Report
Anvil Lake, a relatively shallow seepage lake in northern Wisconsin, USA, has experienced dramatic changes in water level since elevation records began in 1938 in response to changes in meteorological and climatic conditions (Figure 1. Robertson et al., 2018). Anvil Lake’s water level record shows a pronounced 10–15-yr cycle, with...

Kira Mizell, James R. Hein, Manda Viola Au, Amy Gartman
2022, Book chapter, Perspectives on deep-sea mining
Deep-ocean ferromanganese crusts and manganese nodules are important marine repositories for global metals. Interest in these minerals as potential resources has led to detailed sampling in many regions of the global ocean, allowing for updated estimates of their global extent. Here, we present global estimates of total tonnage as well...

2022, Proceedings of the North American Crane Workshop (15) 6-33
Whooping crane (Grus americana) migratory stopovers can vary in length from hours to more than a month. Stopover sites provide food resources and safety essential for the completion of migration. Factors such as weather, climate, demographics of migrating groups, and physiological condition of migrants influence migratory movements of cranes (Gruidae)...

James A. Hunter, Heather L. Crow, William J. Stephenson, Andre J.-M. Pugin, Robert Williams, James B. Harris, Jackson K. Odum, Edward W Woolery
2022, Journal of Seismology (26) 631-652
Reflection and critically refracted seismic methods use traveltime measurements of body waves propagating between a source and a series of receivers on the ground surface to calculate subsurface velocities. Body wave energy is refracted or reflected at boundaries where there is a change in seismic impedance, defined as the product...
Extensive droughts in the conterminous United States during multiple centuries
Gregory J. McCabe, David M. Wolock
2022, Earth Interactions (26) 84-93
Extensive and severe droughts have substantial effects on water supplies, agriculture, and aquatic ecosystems. To better understand these droughts, we used tree-ring-based reconstructions of the Palmer drought severity index (PDSI) for the period 1475–2017 to examine droughts that covered at least 33% of the conterminous United States (CONUS). We identified...

Site response is a critical consideration when assessing earthquake hazards. Site characterization is key to understanding site effects as influenced by seismic site conditions of the local geology. Thus, a number of geophysical site characterization methods were developed to meet the demand for accurate and cost-effective...
Impact of spectral resolution on quantifying cyanobacteria in lakes and reservoirs: A machine-learning assessment
Kiana Zolfaghari, Nima Pahlevan, Caren Binding, Daniela Gurlin, Stefan G.H. Simis, Antonio Ruiz Verdu, Lin Li, Christopher J. Crawford, Andrea VanderWoude, Reagan Errera, Arthur Zastepa, Claude R. Duguay
2022, IEEE Transactions in Geoscience and Remote Sensing (60)
Cyanobacterial harmful algal blooms are an increasing threat to coastal and inland waters. These blooms can be detected using optical radiometers due to the presence of phycocyanin (PC) pigments. The spectral resolution of best-available multispectral sensors limits their ability to diagnostically detect PC in the presence of other photosynthetic pigments....
Broad-scale geographic and temporal assessment of northern long-eared bat (Myotis septentrionalis) maternity colony-landscape association
Katherine M. Gorman, Sabrina M. Deeley, Elaine L. Barr, Samuel R. Freeze, Nicholas Kalen, Michael S. Muthersbaugh, W. Mark Ford
2022, Endangered Species Research (77) 119-130
As the federally threatened northern long-eared bat Myotis septentrionalis continues to decline due to white-nose syndrome (WNS) impacts, the application of effective conservation measures is needed but often hindered by the lack of ecological data. To date, recommended management practices have been adopted in part from other federally listed sympatric species such...

2022, Remote Sensing of the Environment (270)
Mounting evidence indicates dryland ecosystems play an important role in driving the interannual variability and trend of the terrestrial carbon sink. Nevertheless, our understanding of the seasonal dynamics of dryland ecosystem carbon uptake through photosynthesis [gross primary productivity (GPP)] remains relatively limited due in part to the limited availability of...
Acoustic and genetic data can reduce uncertainty regarding populations of migratory tree-roosting bats impacted by wind energy
Amanda Hale, Cris D. Hein, Bethany R. Straw
2022, Animals (12)
Wind turbine-related mortality may pose a population-level threat for migratory tree-roosting bats, such as the hoary bat (Lasiurus cinereus) in North America. These species are dispersed within their range, making it impractical to estimate census populations size using traditional survey methods. Nonetheless, understanding population size and...

Pengfei Wang, Paolo Zimmaro, Tristan E Buckreis, Tatiana Gospe, Scott J Brandenberg, Sean Kamran Ahdi, Alan Yong, Jonathan P. Stewart
2022, Seismological Research Letters (93) 1075-1088
Frequency‐dependent horizontal‐to‐vertical spectral ratios (HVSRs) of Fourier amplitudes from three‐component recordings can provide useful information for site response modeling. However, such information is not incorporated into most ground‐motion models, including those from Next‐Generation Attenuation projects, which instead use the time‐averaged shear‐wave velocity (VS"><span...

N.M. Faucheux, A.R. Sample, C.A. Aldridge, D.M. Norris, C. Owens, Victoria R. Starnes, S. VanderBloemen, Leandro E. Miranda
2022, Water Resources Research (58)
Considering reservoirs as linear fragments in a basin's river network could improve understanding, predictability, and management efficiency. We looked for general cascading spatial patterns across five categories of reservoir attributes: land cover, morphology and hydrology, fish habitat, fish assemblages, and fisheries. Attributes were pulled from various databases for large reservoirs...
A quantitative soil-geomorphic framework for developing and mapping ecological site groups
Travis W. Nauman, Samuel S Burch, Joel T. Humphries, Anna C. Knight, Michael C. Duniway
2022, Rangeland Ecology and Management (81) 9-33
Land management decisions need context about how landscapes will respond to different circumstances or actions. As ecologists’ understanding of nonlinear ecological dynamics has evolved into state-and-transition models (STMs), they have put more emphasis on defining and mapping the soil, geomorphological, and climate...
