Data Releases

Data and code release to evaluate a continuous-flow streamside toxicity test that was conducted with common logperch (Percina caprodes) and larval sea lamprey (Petromyzon marinus) to evaluate the risk posed by 4-nitro-3-(trifluoromethyl)phenol (TFM) sea lamprey control stream treatments to logperch. Logperch are a host to the parasitic glochidia life stage of the federally endangered...

Metals are used in primary producer metabolic pathways, such as photosynthesis and the acquisition of macronutrients nitrogen (N) and phosphorus (P), yet we often do not know their potential as limiting nutrients in freshwaters. In the Great Lakes, metals have sometimes been identified as limiting the acquisition of macronutrients, mostly in off-shore waters that are relatively isolated...

We conducted this study in Upper Mississippi River Pools 4 and 8 to document the occurrence and cover of Phalaris arundinacea and other forest floor plants in UMR floodplain forests and relate measures of abundance of Phalaris, and community composition and diversity to estimates of flood duration which can exhibit high spatial heterogeneity. We used modeled inundation duration which...

Kīlauea Volcano on the Island of Hawai‘i was in a state of nearly continuous eruption from 1983 - 2018. Large amounts of sulfur dioxide gas (SO2) were released from the volcano’s East Rift Zone (ERZ) during the entire eruptive period, and from the Overlook vent at the summit of the volcano from 2008-2018. This data release presents ground-based estimates of SO2 emission rates from the...

This report documents the SO2 emission rates for the period 2014-2017, from the summit and East Rift Zone eruptions of Kīlauea, along with the wind or plume speed and direction data used to calculate the emission rates.

A digital thermal camera was installed at Papaloloa reef on Ofu, American Samoa and faced west along the beach. Every minute from February 3, 2020, to August 1, 2020, the camera collected raw radiometric snapshot images. The camera is part of a U.S. Geological Survey (USGS) research project to study the effects of temperature on coral reef health. USGS researchers analyzed the timestack...
