Lifespan of salt marshes in New York are calculated using conceptual marsh units defined by Defne and Ganju (2018) and Welk and others (2019, 2020a, 2020b, 2020c). The lifespan calculation is based on estimated sediment supply and sea-level rise (SLR) predictions after Ganju and others (2020). Sea level predictions are local estimates which correspond to the 0.3, 0.5, and 1.0 meter increase in Global Mean Sea Level (GMSL) scenarios by 2100 from Sweet and others (2022). The U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands with the intent of providing Federal, State, and local managers with tools to estimate the vulnerability and ecosystem...

This is an SQLite GeoPackage simple feature multilinestring vector database of the Arctic Coastal Plain survey transects in coordinate reference system EPSG:4326. There is one layer for each year 2007 to 2023, although in general the there is a four panel rotation that varies each year. All years are provided because implementation of the panel design varied through time. The field”Year” given the calendar year that the transects were implemented, “Stratum” gives the strata name, “Transect” gives the transect identifier, and the “geom” field gives the simple feature Well Known Text geometry data. Note that these transect are the idealized design and are not an exact record of the true flight path or survey effort....

Aerial survey track files were recorded by each observer using Panasonic Toughpad or Toughbook computers running the software program “RECORD” (John I. Hodges, MBM-Alaska). The RECORD program was activated during the survey before arriving at the first transect and shut down after the last transect was completed, prior to engine shut-down. “Raw” track files recorded the flightpath of the aircraft including the area surveyed on each transect. GPS coordinates were captured every five seconds using a recreational grade receiver with an estimated positional accuracy of 5-10 meters after the software program was activated. These raw track files have not been quality checked, so they may contain missing or erroneous coordinates...

This GeoPackage contains the analysis strata (“YKG_AnalysisStrata”) used in calculating population indices for geese, swans, and cranes. This layer was created from the file (“YKD_DesignStrata”) when the existing rotating panel design was developed in 1999. This layer was originally created as an ArcInfo coverage, saved to a shapefile, and imported to SQLite Database format.

This multi-layer GeoPackage (“VCF_AnalysisStrata”) contains density layers that stratify spectacled eiders into low, medium, and high density classes on the Yukon-Kuskokwim Delta Coastal Zone over two time periods: 1985-1994 and 1995-2015. The (“SPEI_1985to1994_6strata”) and (“SPEI_1995to2015_6strata”) layers were created using ground-based nest data that was log-transformed, interpotated by ordinary kriging methods, and classified into low (0-1.60 km^2), medium (1.60-3.50 km^2), and high (>3.50 km^2) nest density classes. Different visibility correction factors (VCFs) were calculated for each density strata based on the relationship between the nest and aerial survey data. These correction factors are used to produce...

Introduction Relatively little data describing the quality of groundwater in New York State exists, yet groundwater is used as a source of drinking water by approximately one quarter of the population of the state. The objective of the Ambient Groundwater Quality Monitoring project is to quantify and report on ambient groundwater quality from bedrock and glacial-drift aquifers in upstate New York, and is an ongoing cooperative project between the U.S. Geological Survey (USGS) and New York State Department of Environmental Conservation (NYSDEC). The project began in 2002 with a pilot study in the Mohawk River Basin and another in 2003 in the Chemung River Basin. Sampling completed in 2018 represented the conclusion...

This is a folder and zip folder for distribution if the ACP data. Limited metadata exists at this time, thus the readme.txt file contains much of the information. The contents also include 10-02 area data that was collected in 2019. Ths is identified in the 'code' column of the ACP_QCObs_YYYY... files. The contents include: ADDITIONAL INFORMATION: OBSERVATION FILES (Data/ACP_QCObs_YYYY_Name.csv) - 2010 resulted in 3 different observers, 2018 had 1 observer, and all other years had 2 observers. - Latitude and longitude fields are of unknown accuracy and might be 500m from the reported locations due to: (1) GPS satellite accuracy, (2) distance from observed bird to center strip of transect (observer) could be up to...

The Central Valley covers about 20,000 square miles and is one of the most productive agricultural regions in the world. Because the valley is semi-arid, surface-water availability varies substantially. Agricultural demand for irrigation is heavily reliant on surface water and groundwater. In the last few decades, land-use changes and limitations to surface-water availability—including drought and environmental flows—have increased pumping, causing groundwater-level and groundwater-storage declines, renewed subsidence, decreased stream flows, and changes to ecosystems. As these recent trends continue, monitoring, data compilation, and modeling are critical to understanding the dynamics of groundwater use and developing...

This is an SQLite GeoPackage simple feature multipolygon vector database of the Arctic Coastal Plain survey area transect density strata. There is only one layer that gives the strata boundaries in EPSG:4326. The field “Statra” gives the strata name and the “geom” field gives the simple feature Well Known Text geometry data. See the GitHub site for more information. This product was produced from the file ACPmapping.R and is simplified from the original strata files distributed at https://www.sciencebase.gov/catalog/item/65419a58d34ee4b6e05bd001.
