Compilation of Geospatial Data (GIS) for the Mineral Industries and Related Infrastructure of Africa
This geodatabase reflects the U.S. Geological Survey’s (USGS) ongoing commitment to its mission of understanding the nature and distribution of global mineral commodity supply chains by updating and publishing the georeferenced locations of mineral commodity production and processing facilities, mineral exploration and development sites, and mineral commodity exporting ports in Africa. The geodatabase and geospatial data layers serve to create a new geographic information product in the form of a geospatial portable document format (PDF) map. The geodatabase contains data layers from USGS, foreign governmental, and open-source sources as follows: (1) mineral production and processing facilities, (2) mineral exploration...
This study contains TOC and programmed pyrolysis data, as well as vitrinite reflectance collected from 12 samples taken from the Babouri-Figuil Sedimentary basin in northern Cameroon.

Inflow region on the south side of Lake Nyos scoured by the water surge. Lake Nyos gas release disaster, Cameroon. 1986.
Index card: Inflow region on the south side of Lake Nyos scoured by the water surge which followed the emergence of the toxic gas cloud. This is the source of vegetation seen floating on the lake. Damage 25 m above the valley floor. Lake Nyos disaster of August 21, 1986. Cameroon. Photo taken on August 29, 1986.
This zip folder contains ASCII text files of vectors at the specified volcano at 12-hour intervals, from January 1, 1990 through December 28, 2009. The wind vectors are divided into five files, names by their elevation range above sea level in the atmosphere: 00-05km.txt; 05-11km.txt; 11-16km.txt; 16-24km.txt; and 24-30km.txt. The zip folder also contains a subfolder "figures", with Wind rose plots of wind direction and speed over this time period. The plots are by season, and by elevation, given a total of 20 plots (4 seasons, 5 elevation ranges). A summary plot is also included which gives the year-round wind pattern at the volcano, at 0-5 km elevation. Plots are in both jpg and pdf format.
Yale stocks and flows database (YSTAFDB) describing anthropogenic materials cycles, recycling, and criticality for 102 materials on spatial scales ranging from suburbs to global and timescales from the early 1800s to circa 2013
This data release presents the Yale stocks and flows database (YSTAFDB). Its data describe the use of 102 materials from the early 1800s to circa 2013 through anthropogenic cycles, their recycling and criticality properties, and on spatial scales ranging from suburbs to global. This data collection was previously scattered across multiple non-uniformly formatted files such as journal papers, reports, and unpublished spreadsheets. These data have been synthesized into YSTAFDB, which is presented as individual comma-separated text files and also in MySQL and PostgreSQL database formats. Consolidation of these data into a single database can increase their accessibility and reusability, which is relevant to diverse...
Manatee environmental DNA data, and associated attributes, collected from the United States, Cuba, and Cameroon, from 2013-2015
Environmental DNA (eDNA) detection is a rapidly expanding technique used to non-invasively detect cryptic, low density, or logistically difficult-to-study species, such as imperiled manatees. Genetic material shed into the environment through tissue and body fluids is concentrated from water samples and analyzed for the presence of targeted eDNA. To help delineate manatee habitat ranges, high use areas, and seasonal population changes, a cytochrome-b quantitative PCR and state-of-the-art droplet digital PCR (ddPCR) eDNA assay was developed for the three extant and vulnerable manatee species: both subspecies of the West Indian manatee (Florida and Antillean), the African manatee and Amazonian manatee. Occurrence...
