LANDFIRE Remap Anderson Fire Behavior Fuel Model (FBFM13) CONUS

LANDFIRE's (LF) Remap Anderson Fire Behavior Fuel Model 13 (FBFM13) product represents distinct distributions of fuel loadings found among surface fuel components (live and dead), size classes, and fuel types (Anderson 1982). The fuel models are described by the most common fire carrying fuel type (grass, brush, timber, or slash), loading and surface area-to-volume ratio by size class and component, fuel bed depth, and moisture of extinction. FBFM13 can be used for fire spread related characteristic models. 
LF Remap used vegetation products and 10-years of disturbance data to create Fuel Vegetation Type (FVT), Fuel Vegetation Cover (FVC), and Fuel Vegetation Height (FVH) for disturbed areas to represent pre-disturbance scenarios in FBFM13. A combination of pre-disturbance and non-disturbance Existing Vegetation Type (EVT) are used to assign surface fuel models. FBFM13 was developed using the most recent 10 years of Annual Disturbance products and is a capable fuels product that calculates Time Since Disturbance (TSD) assignments for disturbed areas using an effective year. For example, year 2020 fuels may be calculated for the year 2020. This new process considers all the existing disturbances included in LF Remap and adjusts the TSD for these to the effective year (2020 in this example), making the products "2020 capable fuels." More information about capable fuels can be found at https://www.landfire.gov/lf_remap.php.

j695mb.m77t and j695mb.h77t: MGD77T data and header files for single-beam bathymetry data for field activity J-6-95-MB in Monterey Bay from 10/16/1995 to 11/30/1995

Single-beam bathymetry data along with DGPS navigation data was collected as part of the U.S. Geological Survey cruise J-6-95-MB. The cruise was conducted from in Monterey Bay, California from October 16 to November 30, 1995. The chief scientists were Roberto Anima, Andy Stevenson, and Steve Eittreim all from the USGS Coastal and Marine Geology office in Menlo Park, CA.
The purpose of this cruise was to produce a mosaic of the northern Monterey Bay Santuary continental shelf area from as near shore out to the continental slope, and to collect digital subbottom profile data to better understand the shallow tectonics and paleomorphology of the sanctuary. The geophysical source was a Lowrance fathometer.
These data are reformatted from space-delimited ASCII text files located in the Coastal and Marine Geology Program (CMGP) InfoBank field activity catalog at http://walrus.wr.usgs.gov/infobank/j/j695mb/html/j-6-95-mb.meta.html into MGD77T format provided by the NOAA's National Geophysical Data Center(NGDC).

OahuE_ST - Digital Shoreline Analysis System (DSAS) version 4.2 transects with short-term weighted linear regression rate calculations for the Oahu East region from Kahuku to Makapuu, Hawaii.

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate.  Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.
There is no widely accepted standard for analyzing shoreline change.  Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments.  The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast.  The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.

Chukchi Sea Polar Bear Location Data 1985-1996

These data are the raw location data collected from satellite radio-collars fitted on adult female polar bears in the Chukchi Sea, between 1985-1996. The collars were worn by adult female polar bears ranging within the Chukchi Sea subpopulation boundaries as identified by the International Union for the Conservation of Nature's Polar Bear Specialist Group. Agros collars were programmed to transmit for 8 hours centered on 0:00 UTC once every three days.  Thus, for two consecutive days the Agros collar did not transmit location data.

SEABOSS Images from Cruise 2010-015-FA in JPEG Format (2010_015_997PHOTOGRAPHS)

The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Bathymetry and sidescan-sonar imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities in Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. During October 2008 NOAA completed hydrographic survey H11997 offshore in eastern Long Island Sound, and during May 2010 bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Two interpretive data layers were derived from the multibeam echo-sounder and the ground-truth data used to verify them. For more information on the ground-truth survey see https://cmgds.marine.usgs.gov/fan_info.php?fa=2010-015-FA.

Location and radiochemical data from sediment cores collected on Deer Island, Mississippi

In December 2021, four sediment push cores (core names appended with 'M' for marsh push core) and peat augers (core names appended with 'R' for Russian peat auger) were collected from the marshes of Deer Island, Mississippi during U.S. Geological Survey (USGS) field activity number (FAN) 2021-351-FA. Select intervals from the manual push cores were analyzed for determination of lead-210 activities via alpha spectroscopy for development of accumulation rates using standard model methods. Twenty percent of push core samples were counted in triplicate for determination of a lead-210 activity standard deviation. Select intervals were also run on gamma spectroscopy for lead-210 activity validation and cesium-137 activities. Peat augers were collected for determination of peat thickness and were discarded in the field once described and photographed. Core locations were recorded concurrently using real-time kinematic (RTK) positioning for collection of latitude, longitude and elevation (North American Datum of 1983 (2011) [NAD83_2011] and North American Vertical Datum of 1988 [NAVD88], GEOID12B respectively).
