Conclusions of evaluation of restoration for avian species at Caminada Headland and Whiskey Island, Louisiana Conclusions of evaluation of restoration for avian species at Caminada Headland and Whiskey Island, Louisiana
We conducted various analyses to determine the impact of coastal restoration on several focal avian species at Caminada Headland and Whiskey Island, Louisiana. We assessed if restoration affected avian use of restored sites by determining overall habitat changes, occupancy trends, and impacts of construction activities. Here, we summarize our findings from Chapters 2-9. For more details...

Mapping habitats and shorelines pre-, during, and post-restoration on Caminada Headland and Whiskey Island, Louisiana, 2012–2020 Mapping habitats and shorelines pre-, during, and post-restoration on Caminada Headland and Whiskey Island, Louisiana, 2012–2020
Barrier islands and headlands provide ecological services that are integral to economic and environmental interests. Adaptive management may help in ensuring their resilience and the continued provision of ecosystems goods and services over time. The dynamic nature of these environments makes evaluating the impacts from restoration and extreme events an important part of adaptively...

An introduction to the evaluation of restoration for avian species at Caminada Headland and Whiskey Island in Louisiana An introduction to the evaluation of restoration for avian species at Caminada Headland and Whiskey Island in Louisiana
Barrier islands are crucial for protecting Louisiana’s coastal communities and ecosystems as they reduce coastal erosion and help safeguard native flora and fauna. Along the Louisiana shoreline, these islands are mostly long and thin, running parallel to the shoreline. The islands typically consist of the following components: 1) a sandy beach facing the Gulf of Mexico; 2) vegetated and...

An interoperability strategy for the next generation of SEEA accounting An interoperability strategy for the next generation of SEEA accounting
The System of Environmental-Economic Accounting (SEEA) is a set of international environmental-economic standards, adopted by the UN Statistical Commission in 2012 (SEEA Central Framework) and 2021 (SEEA Ecosystem Accounting); the latter in particular requires the integration of large and diverse data streams. These include geospatial and other data sources, which have proven challenging...

Groundwater flow model investigation of the vulnerability of water resources at Chaco Culture National Historical Park related to unconventional oil and gas development Groundwater flow model investigation of the vulnerability of water resources at Chaco Culture National Historical Park related to unconventional oil and gas development
Chaco Culture National Historical Park (CCNHP), located in northwestern New Mexico, protects the greatest concentration of Chacoan historical sites in the American Southwest. Geologically, CCNHP is located within the San Juan structural basin, which consists in part of complex Cretaceous stratigraphy and hosts a variety of energy resources. As part of a larger study to investigate the

Component 1: Data and monitoring gap analysis Component 1: Data and monitoring gap analysis
The goal of Component 1 is to identify available data and data gaps in the Texas coastal region and to establish a plan for obtaining data critical for successful coastal flood analysis in these regions. This component is supporting the expansion and improvement of data observations for inland, coastal, and ocean systems.

An inventory of three-dimensional geologic models—U.S. Geological Survey, 2004–22 An inventory of three-dimensional geologic models—U.S. Geological Survey, 2004–22
A database of spatial footprints and characteristics of three-dimensional geological models that were constructed by the U.S. Geological Survey between 2004 and 2022 was compiled as part of ongoing development of subsurface geologic information by the USGS National Cooperative Geologic Mapping Program. This initial inventory resulted in the compilation of 38 three-dimensional geological...
