Dead Tree Detection Validation Data from Sequoia and Kings Canyon National Parks Dead Tree Detection Validation Data from Sequoia and Kings Canyon National Parks
Most of these data were collected in order to create a database of tree locations for use in calibrating remote sensing tools and products, particularly dead tree detection tools and canopy species maps. Data include tree locations, species identification, and status (live, dead, and, if dead, sometimes includes information on foliage and twig retention). They are a collection of...
Carbon, Nitrogen, and Sulfur Stable Isotopes from Primary Producers, Invertebrates, and Fish at the Nisqually River Delta, Washington from 2011, 2012, and 2015 Carbon, Nitrogen, and Sulfur Stable Isotopes from Primary Producers, Invertebrates, and Fish at the Nisqually River Delta, Washington from 2011, 2012, and 2015
This dataset consists of carbon, nitrogen, and sulfur stable isotope data from primary producers, invertebrates, and fish from the Nisqually River Delta, Washington from 2011, 2012, and 2015. Data were collected to determine food web structure in different habitat zones within the entire river delta. Data collection for primary producers and invertebrates were led by U.S. Geological...
Bayou Bonfouca Marsh Creation (PO-104): 2016 and 2018 land-water classifications Bayou Bonfouca Marsh Creation (PO-104): 2016 and 2018 land-water classifications
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...

Digital elevation model of Mount St. Helens, Washington and vicinity prior to the 1980 eruption Digital elevation model of Mount St. Helens, Washington and vicinity prior to the 1980 eruption
On May 18, 1980, Mount St. Helens, Washington, exploded in a spectacular and devastating eruption that resulted in previously unimaginable events that drastically altered the mountain and the surrounding area. One unprecedented event was the collapse of the summit and north flank of the volcano forming a huge landslide known as the ‘debris avalanche’ with a total volume of about 2.5 km3...
