Paleoseismology and paleogeodesy using coral microatolls Paleoseismology and paleogeodesy using coral microatolls
Establishing the rupture extent and slip distribution of individual paleo-earthquakes is vital for assessing fault behavior including the persistence of rupture segmentation, recurrence patterns, and similarity of successive events, key issues in both fault mechanics and hazard assessment. Techniques with high temporal and geodetic precision as well as a wide distribution of study sites...

History of terrestrial ecosystem development in southern Alexander Archipelago, Alaska since the onset of deglaciation History of terrestrial ecosystem development in southern Alexander Archipelago, Alaska since the onset of deglaciation
This chapter focuses on reconstructing the history of vegetation development in southern Alexander Archipelago (AA) of southeast Alaska during and after deglaciation up to the present day. It also summarizes key findings from recent paleoceanographic research in the Gulf of Alaska to provide a detailed, well-dated record of late Quaternary climate changes for the region. Understanding...

Phenology in higher education Phenology in higher education
Phenological data collection and analysis are well-suited to higher education settings, providing valuable opportunities for hands-on data collection, manipulation, and interpretation. Few subjects are more conducive or accessible for engaging diverse learners in meaningful and impactful science at such large scales and minimal cost. In this chapter, we provide a range of examples of how

Ecosystems Ecosystems
The Fifth National Climate Assessment updates the evidence regarding how climate change influences ecosystems, biological diversity, and the implications for changes to critical ecosystem services—as noted in the key messages above (McElwee et al., 2023). Large-scale transformational changes to ecosystems are occurring, including—but not limited to—land-use conversion, hydrological...

Contribución de la geodesia a la gestión del riesgo volcánico del Nevado del Ruiz Contribución de la geodesia a la gestión del riesgo volcánico del Nevado del Ruiz
Nevado del Ruiz es uno de los volcanes más activos de Colombia. Adquirió una trágica notoriedad a causa de la devastadora erupción ocurrida en noviembre de 1985, que provocó la destrucción de la población de Armero. Desafortunadamente, los limitados datos de deformación recopilados en ese momento no proporcionaron una advertencia clara de la inminente erupción. Desde 1985, el seguimiento...

Pollen records, postglacial: Southeastern North America Pollen records, postglacial: Southeastern North America
Pollen records from the unglaciated southeastern region of North America provide an overview of biogeographic changes associated with vegetational migration northward following the retreat of the Laurentide Ice Sheet. Changing insolation during the Holocene affected forest composition on the Coastal Plain, and rising sea level controlled the distribution of marsh and forested wetlands...

Fish bioenergetics modeling Fish bioenergetics modeling
A bioenergetics model for a fish is defined as a quantitative description of the fish's energy budget. Bioenergetics modeling can be applied to free-ranging fish in rivers, lakes, and oceans to estimate annual food consumption by fish populations; such applications have proven useful in managing fisheries. In addition, bioenergetics models have been used to better understand fish growth...

Amphibian and reptile conservation in the United States of America Amphibian and reptile conservation in the United States of America
Wildlife stewardship is of utmost importance in the United States, where management for sustainable natural resources is extended to native species including amphibians and reptiles. The U.S. wildlife conservation framework is a nested system of authorities regulating species and habitats, science-based management and policy decisions, and adaptive management as new knowledge is applied...

Global Food Security Support Analysis Data (GFSAD) using remote sensing in support of food and water security in the 21st century Global Food Security Support Analysis Data (GFSAD) using remote sensing in support of food and water security in the 21st century
The overarching goal of this chapter is to provide a comprehensive overview of the state-of-art of global cropland mapping procedures using remote sensing as characterized and envisioned by the “Global Food Security Support Analysis Data @ 30 m (GFSAD30)” project working group team. First, the chapter will provide an overview of existing cropland maps and their characteristics along with

A global view of remote sensing of rangelands: Evolution, applications, future pathways A global view of remote sensing of rangelands: Evolution, applications, future pathways
The application of digital remote sensing to rangelands is as long as the history of digital remote sensing itself. Before the launch of the Earth Resources Technology Satellite (ERTS) – later renamed Landsat, scientists were evaluating the use of multispectral aerial imagery to map soils and range vegetation (Yost and Wenderoth 1969). During the late 1960’s, the promise of ERTS...

Seismicity and anisotropic imaging reveal an active detachment beneath the northern Alaska Range foothills Seismicity and anisotropic imaging reveal an active detachment beneath the northern Alaska Range foothills
North of the Denali Fault, the collision between the Yakutat block with North America is accommodated by a fold-thrust belt giving rise to the northern Alaska Range foothills. At the western end, the Kantishna Hills anticline hosts prominent microseismicity and surface deformation, interpreted as active folding of the Kantishna Hills anticline above a midcrustal detachment. We test for...
