The American Community Survey (ACS) is an ongoing survey that provides data every year -- giving communities the current information they need to plan investments and services. The ACS covers a broad range of topics about social, economic, demographic, and housing characteristics of the U.S. population. Much of the ACS data provided on the Census Bureau's Web site are available separately by age group, race, Hispanic origin, and sex.

Selected Population Profiles provide broad social, economic, and housing profiles for a large number of race, ethnic, ancestry, and country/region of birth groups. The data are presented as population counts for the total population and various subgroups and percentages.

The American Community Survey (ACS) is a US-wide survey designed to provide communities a fresh look at how they are changing. The ACS replaced the decennial census long form in 2010 and thereafter by collecting long form type information throughout the decade rather than only once every 10 years. Questionnaires are mailed to a sample of addresses to obtain information about households -- that is, about each person and the housing unit itself.

The American Community Survey (ACS) is a nationwide survey designed to provide communities a fresh look at how they are changing.

Questionnaires are mailed to a sample of addresses to obtain information about households -- that is, about each person and the housing unit itself.

We present an experimental approach to design an over-the-air (OTA) millimeter-wave system for measuring error vector magnitude (EVM) with associated uncertainties that include correlations and nonlinearities. Our approach uses a variable waveguide attenuator at the output of a modulated-signal source at 44 GHz and provides traceable measurements on a calibrated equivalent-time sampling oscilloscope. The conductor-based EVM measurements and associated uncertainties presented here serve as a baseline for the eventual OTA-based EVM.

NOAA-20 (N20/JPSS-1/J1) is the second satellite in the US NOAA latest generation Joint Polar Satellite System (JPSS). N20 was launched on November 18, 2017. In conjunction with the first US satellite in JPSS series, Suomi National Polar-orbiting Partnership (S-NPP) satellite launched on October 28, 2011, N20 form the new NOAA polar constellation. NOAA is responsible for all JPSS products, including SST from the Visible Infrared Imaging Radiometer Suite (VIIRS).

This dataset contains chemical and physical data collected on USCGC Healy during cruise HLY1702 in the Arctic Ocean, Beaufort Sea, and Bering Sea from 2017-08-29 to 2017-09-12. These data include Nitrogen, depth, salinity, sigma-theta potential density, and water temperature. The instruments used to collect these data include CTD Sea-Bird and Isotope-ratio Mass Spectrometer. These data were collected by Mark A.

This dataset contains biological data collected on R/V Endeavor during cruise EN638 from 2019-05-14 to 2019-06-10. These data include depth, leucine incorporation rate, and standard deviation of leucine incorporation rate. The instruments used to collect these data include Liquid Scintillation Counter. These data were collected by Carol Arnosti of University of North Carolina at Chapel Hill as part of the "A mechanistic microbial underpinning for the size-reactivity continuum of dissolved organic carbon degradation (Microbial DOC Degradation)" project.
