Raphael M. Kudela, David B. Senn, Emily T. Richardson, Keith Bouma-Gregson, Brian A. Bergamaschi, Lawrence Sim
2024, Remote Sensing (16)
A massive bloom of the raphidophyte Heterosigma akashiwo occurred in summer 2022 in San Francisco Bay, causing widespread ecological impacts including events of low dissolved oxygen and mass fish kills. The rapidly evolving bloom required equally rapid management response, leading to the use of near-real-time image analysis of chlorophyll from the...

Eric Arthur Scholl, Kyle R. Hanus, Tyler Gardner, Theodore Kennedy
2024, Ecosphere (15)
Predicting how increasing temperatures interact with other global change drivers to influence the structure and dynamics of Earth's ecosystems is a primary challenge in ecology. Our study made use of multiple simultaneous “natural experiments” to examine how rapid warming, declining nutrients, invasive consumers, and...

Alexander P. Graziano, Travis L. Smith, Arthur G. Lilienthal III
2024, Conference Paper, Proceedings of the 2024 Mohawk Watershed Symposium
Between October 31 and November 3, 2019, historic flooding in parts of the Mohawk Valley and southern Adirondack region resulted in one fatality, an estimated $33 million in damages, and the declaration of a state of emergency for 13 New York counties. Flooding resulted from high-intensity rainfall within a 24-hour...

Kimberly R. Beisner, Rebecca E. Travis, David A. Alvarez, Larry B. Barber, Jacob Fleck, Jeramy Roland Jasmann
2024, Emerging Contaminants (10)
Per- and polyfluoroalkyl substances (PFAS) are ubiquitous in the environment but sources are not well defined for temporal and spatial aspects within an urban environment, and especially for an arid urban environment subject to seasonal short term high-intensity precipitation events. A focused diel sampling...
Time of year and weather influence departure decisions of sandhill cranes at a primary stopover
Rachel A. Vanausdall, William L. Kendall, Daniel P. Collins, Quentin R. Hays
2024, Frontiers in Ecology and Evolution (12)
The Rocky Mountain Population (RMP) of greater sandhill cranes uses a key stopover area, the San Luis Valley (SLV) in Colorado. Parameters of migration phenology can differ between autumn and spring and are affected by weather and environmental factors. We hypothesized that sandhill cranes in the SLV would have...

Jennifer L. Shelton, Elias Tejeda
2024, Fact Sheet 2024-3002
The GAMA-PBP is a comprehensive assessment of statewide groundwater quality in California. The first phase of the GAMA-PBP in 2004–15 assessed groundwater resources used for public drinking-water supplies. The second phase is assessing groundwater resources used for domestic drinking-water supplies. An estimated 2 million Californians rely on individual domestic wells...

Rachel R. Renne, Daniel Rodolphe Schlaepfer, Kyle A. Palmquist, William K. Lauenroth, John B. Bradford
2024, Ecosphere (15)
Simulation models are valuable tools for estimating ecosystem response to environmental conditions and are particularly relevant for investigating climate change impacts. However, because of high computational requirements, models are often applied over a coarse grid of points or for representative locations. Spatial interpolation of model output can be necessary to...
Evaluating water-quality trends in agricultural watersheds prioritized for management-practice implementation
James S. Webber, Jeffrey G. Chanat, John W. Clune, Olivia Devereux, Natalie Celeste Hall, Robert D. Sabo, Qian Zhang
2024, Journal of the American Water Resources Assocation (60) 305-330
Many agricultural watersheds rely on the voluntary use of management practices (MPs) to reduce nonpoint source nutrient and sediment loads; however, the water-quality effects of MPs are uncertain. We interpreted water-quality responses from as early as 1985 through 2020 in three agricultural Chesapeake Bay watersheds...
What the cliffs near America’s earliest settlements tell us about climate change
Harry J. Dowsett, Marci M. Robinson
2024, Frontiers for Young Minds (12)
Climate change is a big problem for natural habitats, people, and the systems that support society, including roads, water supply, electrical grids, and phone and internet connections. It’s an important theme in politics, economics, and culture. Scientists make computer models to show what the climate might be like in the...

Lonneke Roelofs, Susan J. Conway, Tjalling de Haas, Colin M. Dundas, Stephen R. Lewis, Jim McElwaine, Kelly Pasquon, Jan Raack, Matt Sylvest, Manish Patel
2024, Communications Earth and Environment (5)
Martian gullies resemble water-carved gullies on Earth, yet their present-day activity cannot be explained by water-driven processes. The sublimation of CO2 has been proposed as an alternative driver for sediment transport, but how this mechanism works remains unknown. Here we combine laboratory experiments of CO2-driven granular flows under Martian atmospheric pressure...

A multi-sensor approach to characterize winter water-level drawdown patterns in lakes
Abhishek Kumar, Allison H. Roy, Konstantinos Andreadis, Xinchen He, Caitlyn Butler
2024, Remote Sensing (16)
Artificial manipulation of lake water levels through practices like winter water-level drawdown (WD) is prevalent across many regions, but the spatiotemporal patterns are not well documented due to limited in situ monitoring. Multi-sensor satellite remote sensing provides an opportunity to map and analyze drawdown frequency and metrics (timing, magnitude, duration)...
