Lake sturgeon seasonal movements in regulated and unregulated Missouri River tributaries
M.J. Moore, Craig P. Paukert, B. Brooke, T. Moore
2022, Ecohydrology (15)
Spatio-temporal movement patterns of aquatic organisms drive many ecological processes. However, dams block migrations and alter the hydrologic and thermal regimes influencing movement behaviour of freshwater fishes. In North America, many recovering southern Lake Sturgeon populations occur in rivers with hydroelectric dams, but few studies have examined the impact of...

2022, Journal of Quaternary Science (37) 928-943
A submillennial-resolution record of lake water oxygen isotope composition (δ18O) from chironomid head capsules is presented from Burial Lake, northwest Alaska. The record spans the Last Glacial Maximum (LGM; ~20–16k cal a bp) to the present and shows a series of large lake δ18O shifts (~5‰)....
Identifying climate-resistant vernal pools: Hydrologic refugia for amphibian reproduction under droughts and climate change
Jennifer M. Cartwright, Toni Lyn Morelli, Evan H. Campbell Grant
2022, Ecohydrology (15)
Vernal pools of the northeastern United States provide important breeding habitat for amphibians but may be sensitive to droughts and climate change. These seasonal wetlands typically fill by early spring and dry by mid-to-late summer. Because climate change may produce earlier and stronger growing-season evapotranspiration combined...

K. Ritenour, Sammy L. King, S. M. Collins, M.D. Kaller
2022, Estuaries and Coasts (45) 897-912
Subsidence and accelerated sea level rise impact nesting area availability and flood probabilities of breeding islands for colonial nesting waterbirds. In 2017 and 2018, we monitored 855 nests of four species of colonial nesting waterbirds on Rabbit Island, LA, to determine factors affecting nest and chick...
Quantifying the response of nitrogen speciation to hydrology in the Chesapeake Bay Watershed using a multilevel modeling approach
Isabella Bertani, Gopal Bhatt, Gary W. Shenk, Lewis C. Linker
2022, Journal of American Water Resources Association (58) 792-804
Excessive nitrogen (N) inputs to coastal waters can lead to severe eutrophication and different chemical forms of N exhibit varying levels of effectiveness in fueling primary production. Efforts to mitigate N fluxes from coastal watersheds are often guided by models that predict changes in N loads...
Short communication: evidence for geologic control of rip channels along Prince Edward Island, Canada
Phillipe Alan Wernette, Chris Houser
2022, Physical Geography (43) 145-162
Rip currents can move unsuspecting swimmers offshore rapidly and represent a significant risk to beach users worldwide, including along the northern coast of Prince Edward Island (PEI), Canada. Although many rip currents are ephemeral and/or spatially variable in response to changes in the nearshore bar morphology and wave and tidal...
Estimating the influence of oyster reef chains on freshwater detention at the estuary scale using Landsat-8 imagery
Alice Alonso, Natalie G. Nelson, Simeon Yurek, David Kaplan, Maitane Olabarrieta, Peter C Frederick
2022, Estuaries and Coasts (45) 1-16
Oyster reef chains grow in response to local hydrodynamics and can redirect flows, particularly when reef chains grow perpendicular to freshwater flow paths. Singularly, oyster reef chains can act as porous dams that may facilitate nearshore accumulation of fresh or low-salinity water, in turn creating intermediate...

A statistical framework to track temporal dependence of chlorophyll–nutrient relationships with implications for lake eutrophication management
Qianlinglin Qiu, Zhongyao Liang, Yaoyang Xu, Shin-Ichiro S. Matsuzaki, Kazuhiro Komatsu, Tyler Wagner
2021, Journal of Hydrology (603)
A reliable chlorophyll–nutrient relationship (CNR) is essential for lake eutrophication management. Although the spatial variability of CNRs has been extensively explored, temporal variations of CNRs at the individual lake scale has rarely been discussed. The paucity of information about temporal dependence in CNRs may in part be due to the...

Experimental tree mortality does not induce marsh transgression in a Chesapeake Bay low-lying coastal forest
David C Walters, Joel A. Carr, Alyssa Hockaday, Joshua A Jones, Eliza McFarland, Katya Kovalenko, Matthew L. Kirwan, Donald Cahoon, Glenn R. Guntenspergen
2021, Frontiers in Marine Science (8)
Transgression into adjacent uplands is an important global response of coastal wetlands to accelerated rates of sea level rise. “Ghost forests” mark a signature characteristic of marsh transgression on the landscape, as changes in tidal inundation and salinity cause bordering upland tree mortality, increase light availability, and the...

S. Jerrod Smith, Elise M. Sherrod
2021, Scientific Investigations Map 3482
Hydrologic records used to create previously published maps depicting mean annual runoff are biased to a relatively dry period in Oklahoma history that was dominated by droughts. Therefore, the U.S. Geological Survey, in cooperation with the Oklahoma Water Resources Board, developed an updated mean annual runoff and annual runoff...

Understanding the potential changes in hydrology and water temperature as a result of climate change is important to this priority for evaluating...
Streambed scour of salmon (Oncorhynchus spp.) redds in the Sauk River, Northwestern Washington
Andrew S. Gendaszek
2021, Scientific Investigations Report 2021-5133
The autumn and winter flood season of western Washington coincides with the incubation period of many Pacific salmon (Onchorhynchus spp.) populations. During this period, salmon embryos incubating within gravel nests called “redds” are vulnerable to mobilization of surrounding sediment during floods. As overlying sediment is transported downstream, the vertical...

Christopher F. Waythomas
2021, Frontiers in Earth Science (9)
This study addresses the characteristics, potential hazards, and both eruptive and non-eruptive role of water at selected volcanic crater lakes in Alaska. Crater lakes are an important feature of some stratovolcanoes in Alaska. Of the volcanoes in the state with known Holocene eruptive activity, about one third have summit crater...

Janet R. Barclay, John R. Mullaney
2021, Scientific Investigations Report 2021-5116
Aquatic systems in and around the Long Island Sound (LIS) provide a variety of ecological and economic benefits, but in some areas of the LIS, aquatic ecosystems have become degraded by excess nitrogen. A substantial fraction of the nitrogen inputs to the LIS are transported through the groundwater-flow system. Because...

Ryan M. Fitzpatrick, Dana L. Winkelman, Brett M. Johnson
2021, Fishes (6)
Otolith microchemistry has emerged as a powerful technique with which to identify the natal origins of fishes, but it relies on differences in underlying geology that may occur over large spatial scales. An examination of how small a spatial scale on which this technique can be implemented, especially in...
