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.

Cenozoic Calcareous Nannofossil Occurrences from South Atlantic Coastal Plain Cores Cenozoic Calcareous Nannofossil Occurrences from South Atlantic Coastal Plain Cores
In this data release, Cenozoic calcareous nannofossil occurrence charts are provided as Microsoft Excel spreadsheets for 17 cores from the South Atlantic Coastal Plain (North Carolina, South Carolina, and Georgia) Samples have been assigned a USGS sample number and are organized by depth below the land surface. Based on their known stratigraphic position, lithology, and specific...
Cenozoic Calcareous Nannofossil Occurrences from Gulf Coastal Plain Cores and Outcrops Cenozoic Calcareous Nannofossil Occurrences from Gulf Coastal Plain Cores and Outcrops
In this data release, Cenozoic calcareous nannofossil occurrence charts are provided as Microsoft Excel spreadsheets for 15 cores or outcrops from the Gulf Coastal Plain (Alabama, Mississippi, and Georgia). Samples have been assigned a USGS sample number and are organized by depth below (cores and wells) or height above (outcrops) the land surface. Based on their known stratigraphic...
Biomass accrual and trace-element concentrations in water and periphytic algae at select locations in the Clark Fork and Blackfoot Rivers, Montana, 2015 Biomass accrual and trace-element concentrations in water and periphytic algae at select locations in the Clark Fork and Blackfoot Rivers, Montana, 2015
The U.S. Geological Survey monitored algal biomass accrual and concentrations of metals and other trace elements in stream water and periphytic algae at 3-4 day intervals over a 2-week period at 3 locations within the upper and middle portions of the mining-impacted Clark Fork River, Montana, and at one location on the relatively unimpacted Blackfoot River tributary. This data release...
Repeat microgravity data from Mesilla Valley, New Mexico, 2016-2018 Repeat microgravity data from Mesilla Valley, New Mexico, 2016-2018
This dataset represents the network-adjusted results of relative- and absolute-gravity surveys. Relative-gravity surveys were carried out using a Zero Length Spring, Inc. relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations...
Time Series of Autonomous Carbonate System Parameter Measurements in Eastern Gulf of Mexico near Tampa Bay, Florida, USA Time Series of Autonomous Carbonate System Parameter Measurements in Eastern Gulf of Mexico near Tampa Bay, Florida, USA
This data set contains time series measurements of carbonate system parameters including water temperature (degrees C), pressure (dbars), salinity, pHT (pH on the total scale), carbon dioxide (ppm), dissolved oxygen (milligrams/L), and photosynthetically active radiation (microEinsteins). These data were collected in the eastern Gulf of Mexico near Tampa Bay, Florida, at the University...

Hawaii Island bird response to koa moth outbreak, 2013-2014 Hawaii Island bird response to koa moth outbreak, 2013-2014
This data release includes metadata and tabular data that document the responses of birds to changes in habitat conditions before and after koa (Acacia koa) defoliation by koa moths (Scotorythra paludicola). Data sets document changes in the (1) use of tree species, (2) arthropod composition of diets, and (3) body mass.
Hakalau Forest NWR seed rain, seedling, and plant data for 2017-2019 Hakalau Forest NWR seed rain, seedling, and plant data for 2017-2019
This data release includes data and metadata on tree and shrub basal area as well as bird-mediated and passive seed rain for sites selected to have a range of understory cover under canopy trees (Metrosideros polymorpha and Acacia koa). It also includes seedling germination and survival data for a large-scale seed addition and grass removal experiment that varied both seed rain and grass...
Hawaii Island locations of reintroduced Alala from automated radio telemetry tracking system, 2017 cohort Hawaii Island locations of reintroduced Alala from automated radio telemetry tracking system, 2017 cohort
Alala, or Hawaiian Crow (Corvus hawaiiensis), were extinct in the wild since the early 2000s. The first effort to reintroduce captive bred Alala back into the wild was conducted at Puu Makaala Natural Area Reserve on Hawaii Island. The 2017 release cohort were released in two stages and were the only Alala in the wild. Using automated radio telemetry tracking towers (n=4) that were...
