Data

This preliminary product contains annual land cover, land use, and change process variables for reference data plots in a .csv table. The same information available in the.csv file is also provided in a .xlsx format. The LCMAP Preliminary Duplicate Attributes Collection for Reference Data includes the attributes collected from 30-meter by 30-meter plots across the conterminous United...

In order to understand the provenance of lead in the surface water, groundwater, soils, and shallow pore water within and near the Middleton Municipal Airport–Morey Field (C29) in Middleton, WI, a subset of samples were sent to the Wisconsin State Lab of Hygiene for analysis. The results of these analyses are included in this data release and include both low-level lead concentrations...

Sediment samples were collected from Los Padres reservoir in the Carmel River watershed, central California coast, between July 11 and 17, 2017, using a CME-45 barge-mounted drill rig, to characterize sedimentary properties in the reservoir deposits following the Soberanes Fire of 2016 and high river flows in winter 2017. Borehole samples were recovered using direct push coring with an...

Landsat Extended Acquisitions of the Poles (LEAP) imaging plan is a Landsat special request data collection program for Earth's polar regions that include Antarctica, Greenland, and Arctic sea ice geographies. The LEAP program includes Landsat 8 and Landsat 9 observatories that operationally acquire spaceborne images of all Earth's land surface and near-shore coastal environments. These...

Data include lengths, observations on piscivory, and hatch dates for age-0 largemouth bass in Wisconsin lakes with predicted total length (TL) if the fish would have hatched 7 days earlier or 7 days later.

Letter concerning Apollo 17 training exercises at Nevada Test Site

This is a letter from E. M. Shoemaker to E. P. Henderson requesting samples from Meter Crater, AZ, that were being held there.

This is a letter from John O'Keefe to Eugene Shoemaker discussing Lunar rays and formulas for computing impact crater ray formation.

This data release defines beach volumes and shoreline change for each 10-meter-wide profile along the New Jersey and New York coastline. The profiles are derived from light detection and ranging (lidar)-digital elevation models (DEMs). These data support the National Fish and Wildlife Foundation (NFWF)-funded project entitled “Monitoring Hurricane Sandy Beach and Marsh Resilience in New...

The lifespans of salt marshes in Connecticut are calculated based on estimated sediment supply and sea-level rise (SLR) predictions, following the methodology of Ganju and others (2020). The salt marsh delineations are from Ackerman and others (2023). The SLR predictions are local estimates corresponding to increases of 0.3, 0.5 and 1.0 meter in global mean sea level (GMSL) by 2100, as...

The lifespans of salt marshes in Atlantic-facing Eastern Shore of Virginia are calculated based on estimated sediment supply and sea-level rise (SLR) predictions, following the methodology of Ganju and others (2020). The salt marsh delineations are from Ackerman and others (2023). The SLR predictions are local estimates corresponding to increases of 0.3, 0.5 and 1.0 meter in global mean...

*This dataset is revised due to a revision of the Eastern Long Island dataset. Please see the process steps below for full details.* 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)...
