John W. Jones
Through my research, I pursue two over-riding goals: (1) increased understanding of relationships among land surface dynamics, hydrologic, and biologic processes; and (2) the provision of resource management relevant information to decision-makers. To meet these goals, research is focused on developing new methods to measure and monitor biophysical characteristics of various land covers.
John has been developing and applying geospatial technologies to improve process understanding and resource management for nearly four decades. His current emphasis is on the development and application of methods and products to monitor inland surface water dynamics from local through global scales. He is particularly interested in the fusion of data collected by various sensors to provide the highest quality time-series data possible. Collaboration across disciplines and institutions improves the quality of his work. Before joining the USGS, John worked as a geospatial technology applications specialist in state government and private industry. Since joining the USGS, John has engaged in research, strategic planning, training, mentoring, and outreach. Specific research endeavors have included: snow cover mapping; incorporating remote sensing and landscape ecology in Everglades restoration science; wetland bathymetry modeling; evaluating the role of vegetation in hydrology (e.g., spatial and temporal variations in evapotranspiration; precipitation interception and resistance to surface water flow); land surface phenology; impervious surface data accuracy assessment; mapping irrigated lands and estimating agricultural water use; land surface inundation/depth dynamics - especially in wetlands; remote sensing of river discharge; and hazard mitigation.

Estimating evaporative fraction from readily obtainable variables in mangrove forests of the Everglades, U.S.A.
A remote-sensing-based model to estimate evaporative fraction (EF) – the ratio of latent heat (LE; energy equivalent of evapotranspiration –ET–) to total available energy – from easily obtainable remotely-sensed and meteorological parameters is presented. This research specifically addresses the shortcomings of existing ET retrieval methods such as calibration requirements of extensive accurate inAuthorsAli Levent Yagci, Joseph A. Santanello, John Jones, Jordan G. BarrEngaging the user community for advancing societal applications of the Surface Water Ocean Topography mission
Scheduled for launch in 2021, the Surface Water and Ocean Topography (SWOT) mission will be a truly unique mission that will provide high-temporal-frequency maps of surface water extents and elevation variations of global water bodies (lakes/reservoirs, rivers, estuaries, oceans, and sea ice) at higher spatial resolution than is available with current technologies (Biancamaria et al. 2016; AlsdorfAuthorsFaisal Hossain, Margaret Srinivasan, Craig Peterson, Alice Andral, Ed Beighley, Eric Anderson, Rashied Amini, Charon Birkett, David M.

Methods to estimate irrigation withdrawal using nationally available datasets and techniques that are transferable to other agricultural regions were evaluated by the U.S. Geological Survey as part of the Apalachicola-Chattahoochee-Flint (ACF) River Basin focus area study of the National Water Census (ACF–FAS). These methods investigated the spatial, temporal, and quantitative distributions of watAuthorsJaime A. Painter, Lynn J.

Fire occurs naturally in the environment on most continents, including Africa (Ryan and Williams, 2011), Asia (Kauhanen, 2008), Australia (Kutt and Woinarski, 2007), Europe (Eshel and others, 2000), South America (Fidelis and others, 2010), and North America (Van Auken, 2000). Antarctica appears to be the only continent that has no reported natural fires, although fire is common in grasslands of PAuthorsThomas J. Smith, Ann M.

The U.S. Geological Survey is developing new Landsat science products. One, named Dynamic Surface Water Extent (DSWE), is focused on the representation of ground surface inundation as detected in cloud-/shadow-/snow-free pixels for scenes collected over the U.S. and its territories. Characterization of DSWE uncertainty to facilitate its appropriate use in science and resource management is a primaAuthorsJohn JonesMonitoring Everglades freshwater marsh water level using L-band synthetic aperture radar backscatter
The Florida Everglades plays a significant role in controlling floods, improving water quality, supporting ecosystems, and maintaining biodiversity in south Florida. Adaptive restoration and management of the Everglades requires the best information possible regarding wetland hydrology.

Construction of small reservoirs affects ecosystem processes in numerous ways including fragmenting stream habitat, altering hydrology, and modifying water chemistry. While the upper and middle Chattahoochee River basins within the Southeastern United States Piedmont contain few natural lakes, they have a high density of small reservoirs (more than 7500 small reservoirs in the nearly 12,000 km2 baAuthorsAmber R. Ignatius, John JonesLinking river management to species conservation using dynamic landscape scale models
Efforts to conserve stream and river biota could benefit from tools that allow managers to evaluate landscape-scale changes in species distributions in response to water management decisions. We present a framework and methods for integrating hydrology, geographic context and metapopulation processes to simulate effects of changes in streamflow on fish occupancy dynamics across a landscape of inteAuthorsMary Freeman, Gary R.

A hydrologic model of the Apalachicola–Chattahoochee–Flint River Basin (ACFB) has been developed as part of a U.S. Geological Survey (USGS) National Climate Change and Wildlife Science Center effort to provide integrated science that helps resource managers understand the effect of climate change on a range of ecosystem responses.

Ecotones are areas of sharp environmental gradients between two or more homogeneous vegetation types. They are a dynamic aspect of all landscapes and are also responsive to climate change. Shifts in the position of an ecotone across a landscape can be an indication of a changing environment. In the coastal Everglades of Florida, USA, a dominant ecotone type is that of mangrove forest and marsh. HoAuthorsThomas J. Smith, Ann M.

The ability to document the frequency, extent, and severity of fires in wetlands, as well as the dynamics of post-fire wetland land cover, informs fire and wetland science, resource management, and ecosystem protection. Available information on Everglades burn history has been based on field data collection methods that evolved through time and differ by land management unit.

Fire is a major factor in the Everglades ecosystem. For thousands of years, lightning-strike fires from summer thunderstorms have helped create and maintain a dynamic landscape suited both to withstand fire and recover quickly in the wake of frequent fires. Today, managers in the Everglades National Park are implementing controlled burns to promote healthy, sustainable vegetation patterns and ecosAuthorsJohn Jones - News
