2023, Water (15)
Extreme water-level recurrence estimates for a complex estuary using a high-resolution 2D model and a new method for estimating remotely generated sea level anomalies (SLAs) at the model boundary have been developed. The hydrodynamic model accurately resolves the dominant physical processes contributing to extreme water levels across the Washington...
A simple approach to modeling light attenuation in the Sacramento-San Joaquin Delta using commonly available data
Emily T. Richardson, Keith Bouma-Gregson, Katy O'Donnell, Brian A. Bergamaschi
2023, San Francisco Estuary and Watershed Sciences (21)
The diffuse attenuation coefficient of photosynthetically active radiation (KdPAR) is commonly used to predict light attenuation in aquatic productivity models, but obtaining measurements of PAR to compute KdPAR is difficult. In situ calculations of KdPAR require multiple measurements of PAR through the...

Hawksbill and green turtle niche overlap in a marine protected area, US Virgin Islands
Melissa A. Moorehouse, John D. Baldwin, Kristen Hart
2023, Endangered Species Research (52) 265-283
Studying how species interact with their environment and other co-occurring species are 2 main aspects of ecology. For marine turtles, ocean currents drive migratory routes and may determine the location of surrounding foraging grounds. As a result, circumglobal species like the hawksbill turtle Eretmochelys imbricata and green turtle Chelonia mydas adapt to diverse foraging...

Josh Adams, Jonathan J. Felis, Robert C. Klinger, Emily C. Kelsey, Joy Tamayose, Raina Kaholoa'a, Cathleen Natividad Bailey, Jay F. Penniman, Jennifer Learned, Ciara Ganter, John Medeiros, Huisheng Chen
2023, Endangered Species Research (52) 231-246
Haleakalā National Park and montane areas on east Maui, Hawaiian Archipelago, support critical nesting habitat for endangered ‘ua‘u Hawaiian petrel Pterodroma sandwichensis. Habitat loss, non-native predators, and damage by feral ungulates are limiting factors for ground-nesting petrels at Haleakalā and throughout Hawai‘i. Because nesting habitats differ among the Hawaiian Islands,...
Micropaleontological evidence of a submarine fan in the lower Coaledo Formation, Southwestern Oregon, USA
Kristin McDougall-Reid
2023, Journal of Foraminiferal Research (53) 311-337
The middle Eocene lower Coaledo Formation was interpreted as ten shoaling upward delta-margin cycles based on sediments and macrofauna. The strata, however, contains deep-water foraminifers. Explanations to resolve this anomaly included reworking, bathymetric range extension, or upward migration of water masses. Paleoecology analysis...

2023, Wetlands (43)
Wetlands cover a small portion of the world, but have disproportionate influence on global carbon (C) sequestration, carbon dioxide and methane emissions, and aquatic C fluxes. However, the underlying biogeochemical processes that affect wetland C pools and fluxes are complex and dynamic, making measurements of wetland C challenging. Over decades...
Editorial: Remote sensing of volcanic gas emissions from the ground, air, and space
Christoph Kern, Santiago Arellano, Robin Campion, Silvana Hidalgo, Ryunosuke Kazahaya
2023, Frontiers in Earth Science (11)
When magma rises in volcanic systems, volatile species exsolve from the melt and are outgassed to the atmosphere. The melt composition and temperature, depth at which degassing occurs, extent of gas-water-rock interactions, and volume of ascending magma are all factors that determine the composition and rate of gas emissions at...
