Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Reference genome for Phragmites australis (Poaceae, subfamily Arundinoideae) and comparison of North American invasive genotype (ssp. australis) and native (ssp. americanus) Reference genome for Phragmites australis (Poaceae, subfamily Arundinoideae) and comparison of North American invasive genotype (ssp. australis) and native (ssp. americanus)
These data represent the first reference genome for the invasive Phragmites australis ssp. australis (1.14 giga base pairs (Gbp)), as well as output from comparative genomic and transcriptomic analyses for invasive and native genotypes coexisting in the Great Lakes region of North America. Genome sequencing data used tillers and associated rhizome tissues collected from a single P...
Vegetation Types in Coastal Louisiana in 2021 (ver. 2.0, April 2023) Vegetation Types in Coastal Louisiana in 2021 (ver. 2.0, April 2023)
Coastwide vegetation surveys have been conducted multiple times over the past 50 years (e.g. Chabreck and Linscombe 1968, 1978, 1988, 1997, 2001, and 2013) by the Louisiana Department of Wildlife and Fisheries (LDWF) in support of coastal management activities. The last survey was conducted in 2013 and was funded by the Louisiana Coastal Protection and Restoration Authority (CPRA) and...

Historical simulated snowpack for the Lake Sherburne, MT watershed and vicinity, water years 1980-2019 Historical simulated snowpack for the Lake Sherburne, MT watershed and vicinity, water years 1980-2019
Abstract This data release contains historical SnowModel (Liston and Elder, 2006) output for the Lake Sherburne, MT watershed and surrounding area. The two quantities simulated for this release were snow water equivalent depth (swed), the liquid water equivalent depth stored as snow in the simulation domain, and runoff (roff), which includes snowmelt at the snow-soil interface and...
Reflectance and spectral fluorescence data from the effect of diagenesis on the preservation of morphology and ultrastructural features of pollen Reflectance and spectral fluorescence data from the effect of diagenesis on the preservation of morphology and ultrastructural features of pollen
Pollen morphology and pollen morphology in conjunction with other characteristics have elucidated the origin and evolution of various plant groups. Many studies of fossil pollen rarely discuss the effects of diagenesis and sample preparation on pollen characteristics. This paper examines the relationship of diagenesis, sample preparation (e.g., acetolysis), and staining techniques on the
