Seasonal change is important to consider when managing conservation areas at landscape scales. The study of such patterns throughout the year is referred to as phenology. Recurring life-cycle events that are initiated and driven by environmental factors include animal migration and plant flowering. Phenological events capture public attention, such as fall color change in deciduous forests, the first flowering in spring, and for those with allergies, the start of the pollen season. These events can affect our daily lives, provide clues to help understand and manage ecosystems, and provide evidence of how climate variability can affect the natural cycle of plants and animals. Phenological observations can be gathered...
The Dam Removal Information Portal (DRIP) is an online representation and visualization tool for the USGS Dam Removal Science Database, inspired by Bellmore et al. 2015 and now developed as a live data system in ScienceBase as part of the Biogeographic Information System. DRIP provides a map-based visualization of information of dam removals and associated scientific studies. The database was developed in cooperation with the NGO, American Rivers, who also provides data on other dam removals that lack associated scientific studies. The original software for the online DRIP application was developed in cooperation with AppGeo. Basic information about the dam’s location, size, date built and date removed are provided...
The increasing availability of climate projections provides natural resource managers and scientists with a number of scenarios from which to estimate variability in hydrologic response to future climatic conditions. This presents a need for consistent and efficient conversion of climate data into model-ready format, archiving and indexing of model simulation results, and the visualization and summation of model simulation results. Furthermore, decision-makers need this information at specific locations and for specific periods of record to effectively manage their water resources. This final report summarizes a collaborative effort to help address these issues through the construction of the Monthly Water Balance...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
