Pine species distribution maps of the Madrean Sky Islands, United States and Mexico Pine species distribution maps of the Madrean Sky Islands, United States and Mexico
This dataset includes raster species distribution models of five pine species in the Madrean sky islands of Mexico and the United States. Models were trained using a large bi-national field dataset (n = 1,416) of pine species observations. Species distribution models were created for the following pine species: P. arizonica (syn. P. ponderosa var. arizonica); P. discolor (syn. P...
Pinyon-juniper basal area, climate and demographics data from National Forest Inventory plots and projected under future density and climate conditions Pinyon-juniper basal area, climate and demographics data from National Forest Inventory plots and projected under future density and climate conditions
These data were compiled to help understand how climate change may impact dryland pinyon-juniper ecosystems in coming decades, and how resource management might be able to minimize those impacts. Objective(s) of our study were to model the demographic rates of PJ woodlands to estimate the areas that may decline in the future vs. those that will be stable. We quantified populations growth...
PlanetScope and DESIS spectral library of agricultural crops in California's Central Valley for the 2020 growing season PlanetScope and DESIS spectral library of agricultural crops in California's Central Valley for the 2020 growing season
Here we provide information for the PlanetScope and d Deutsches Zentrum fur Luft- und Raumfahrt (DLR) Earth Sensing Imaging Spectrometer (DESIS) Derived Spectral Library of Agricultural Crops in California which was developed using PlanetScope Dove-R high spatial resolution data and DESIS hyperspectral data acquired for 2020. PlanetScope images are available through Planet Labs (2022)...
Planktonic foraminifer census data from type section of Yorktown Formation at Rushmere, Virginia, USA Planktonic foraminifer census data from type section of Yorktown Formation at Rushmere, Virginia, USA
Data consist of census counts of Pliocene planktonic foraminifera from the lectostratotype of the Yorktown Formation at Rushmere Virginia, Rice's Pit, Yorktown, and the type section of the Morgarts Beach Member at Morgarts Beach, Virginia. In total, counts of individuals from 12 samples and 25 species are included.
Plotting multiple fault representations: Applications for National Seismic Hazard Model 2023 update (NSHM-faultmaps) Plotting multiple fault representations: Applications for National Seismic Hazard Model 2023 update (NSHM-faultmaps)
The National Seismic Hazard Model (NSHM) utilizes a fault sections database (FSD) throughout the model workflow. Working towards a 2023 NSHM release, the NSHM23 FSD encompasses a major update with the addition of new fault sections, as well as the revision of existing fault sections from prior FSD (2014). The additions and revisions were largely based on the U.S. Geological Survey's...
Point Raw Glaciological Data: Ablation Stake, Snow Pit, and Probed Snow Depth Data on USGS Benchmark Glaciers Point Raw Glaciological Data: Ablation Stake, Snow Pit, and Probed Snow Depth Data on USGS Benchmark Glaciers
This dataset contains point raw glaciological field data. Snow pit and snow core data give detailed information on snow density through the measured snow column. Snow depth measurements are collected via snow probe and in some snow pits or snow cores that extend the full depth of the snowpack to the glacier's surface. Ablation stakes allow point measurement of both snow depth and snow...
Point Sampling Data for Eelgrass (Zostera marina) and Widgeongrass (Ruppia marina) Abundance in Embayments of the North Pacific Coast of Baja California, Mexico Point Sampling Data for Eelgrass (Zostera marina) and Widgeongrass (Ruppia marina) Abundance in Embayments of the North Pacific Coast of Baja California, Mexico
These data are in seven tables relating to surveys of eelgrass (Zostera marina) and widgeongrass (Ruppia maritima) beds in embayments of the north Pacific coast of Baja California, Mexico. The tables provide environmental conditions, eelgrass and widgeongrass abundance, and measurements used to estimate their aboveground biomass. These tables also provide information on percent cover...
Point Sampling Data from Eelgrass (Zostera marina), Seaweeds and Selected Invertebrates at Six Embayments and Two Islands at the End of the Alaska Peninsula Point Sampling Data from Eelgrass (Zostera marina), Seaweeds and Selected Invertebrates at Six Embayments and Two Islands at the End of the Alaska Peninsula
This dataset is from surveys for the abundance and distribution of eelgrass and seaweeds that were made at six embayments and two offshore islands at the southwestern end of the Alaska Peninsula in August-September 2012. The five tables provide information on percent cover and location of eelgrass and seaweeds, presence and absence of selected invertebrates, locations of eelgrass genetic...
Point Sampling for Eelgrass (Zostera marina) and Seaweeds in Duchikthluk and Shoal Bays of Nunivak Island, Alaska, 2010 Point Sampling for Eelgrass (Zostera marina) and Seaweeds in Duchikthluk and Shoal Bays of Nunivak Island, Alaska, 2010
These data are in seven tables relating to surveys of eelgrass beds in Duchikthluk and Shoal Bays of Nunivak Island, Alaska. The tables provide environmental conditions, eelgrass abundance, distribution, and measurements used to estimate overall biomass. These tables also provide information on percent cover and location of eelgrass and seaweeds/bluegreen algae, biomass of eelgrass...
Polar Bear Continuous Time-Correlated Random Walk (CTCRW) Location Data Derived from Satellite Location Data, Chukchi and Beaufort Seas, July-November 1985-2017 Polar Bear Continuous Time-Correlated Random Walk (CTCRW) Location Data Derived from Satellite Location Data, Chukchi and Beaufort Seas, July-November 1985-2017
This dataset consists of one table with estimated locations of adult female polar bears during July-November 1985-2017, used for quantifying changes in summer land use over time. Locations were estimated with a Continuous Time-Correlated Random Walk (CTCRW) model fit to satellite tracking from radio-collared adult female polar bears. All bears included in this data set were captured and
Polar Bear Fall Coastal Survey Data from the Southern Beaufort Sea of Alaska, 2010-2013 Polar Bear Fall Coastal Survey Data from the Southern Beaufort Sea of Alaska, 2010-2013
This data set is one table with observations of polar bears located during aerial surveys along the coast and barrier islands of the southern Beaufort Seas during fall, 2010-2013. Survey flights were conducted using A-Star B2 and Bell 206 helicopters at an average altitude of 300 feet AGL and an average speed of 50 miles per hour.
