Ellsworth Huntington’s (1914) giant sequoia ages and tree-ring measurements from 458 stumps in Sequoia National Forest and Mountain Home Grove

These data include giant sequioa (Sequoiadendron giganteum) age and tree-ring data from measurements on 458 stumps.  The original data were recorded on paper data sheets by Ellsworth Huntington and his assistants in 1911 and 1912; their methods are elaborated in Huntington (1914), and further details can be found in Stephenson and Demetry (1995).  We entered the data from photocopies of the original data sheets which, to the best of our knowledge, reside at Yale University.  The photocopies apparently were made in the late 1960s or early 1970s and were housed in Sequoia National Park’s archives.
Most of Huntington’s 458 measured giant sequoia stumps were in or near what is now the Hume Lake District of Sequoia National Forest (Giant Sequoia National Monument), California, particularly the Converse Basin Grove; however, about 17 percent came from in or near what is now Mountain Home Demonstration State Forest, about 70 km to the SSE.
Data for each tree (stump) consist of from one to five readings of the widths (to the nearest 0.5 mm) of groups of 10 tree rings along unique radii.  When only one or two radii were measured on a stump, we entered the data for each radius.  When three, four, or five radii were measured, we entered data from two radii whose directions differed by at least 90 degrees, whenever possible.  The choice of entering data from widely separated radii was made by Stephenson and Demetry (1995), who wished to determine the effects of two widely separated increment cores on the accuracy and precision of age estimates for giant sequoias.  Sometimes, “DO NOT USE” was written by Huntington across a radius’ readings, usually because that radius came out several to many decades younger than the oldest radius for that tree.  If such a radius normally would fit our criterion to be entered in the database (because it was separated by at least 90 from the other radius we entered), a judgement was made.  Generally, if the difference was at least 50 years, a different radius whose count better agreed with the largest count was chosen, regardless of its direction.

Water Temperature and Specific Conductance in the Chicago Sanitary and Ship Canal Near the Electrical Dispersal Barrier System at Romeoville, Illinois, October 1, 2017, to September 30, 2018

Water temperature (degrees Celsius) and specific conductance (microsiemens per centimeter at 25 degrees Celsius; TC) were measured at U.S. Geological Survey streamgage 05536995, located at Chicago Sanitary and Ship Canal near the Electrical Dispersal Barrier System in Romeoville, Illinois. The TC data were measured every five minutes at four gage height levels above the gage datum (P1 = 21 feet, P2 = 17 feet, P3 = 13 feet, P4 = 9 feet). The gage datum is 551.76 feet above the North American Vertical Datum of 1988 (NAVD 88). Daily mean and five-minutes water temperature and specific conductance data were downloaded from the National Water Information System (NWIS) database and stored in Comma Separated Values (CSV) files. Daily mean data are stored in a CSV file, "05536995-WY2018-temp-speccond-dailymean.csv" and the data measured every five minutes in "05536995-WY2018-temp-speccond-five-minute.csv." The 7-day moving average of daily mean values was calculated in a custom Python script. For each day, the 7-day moving average was calculated as the average of daily mean value for that day and the six previous days. This spreadsheet was saved as a CSV file, "05536995-WY2018-temp-speccond-7daymovavg.csv." The water year 2018 annual minimum, maximum, mean, median, and standard deviation were calculated for each of the four temperature probes and the four specific conductance probes in a custom Python script and saved as a CSV file, "05536995-WY2018-temp-speccond-annualstats.csv". The CSV files containing five-minute, daily mean, 7-day moving average, and annual statistics (minimum, maximum, mean, median, and standard deviation) for water year 2018 can be downloaded from this page.

Seafloor Elevation Change From 2016 to 2017 at Crocker Reef, Florida Keys-Impacts From Hurricane Irma

The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify bathymetric changes at Crocker Reef near Islamorada, Florida (FL), within a 33.6 square-kilometer area following the landfall of Hurricane Irma in September 2017. USGS staff used light detection and ranging (lidar)-derived data acquired by the National Oceanic and Atmospheric Administration (NOAA) between July 21 and November 21, 2016 and USGS multibeam data collected between October 10 and December 8, 2017 (Fredericks and others, 2019) to assess changes in seafloor elevation and structure that occurred after the passage of Hurricane Irma. An elevation change analysis between the 2016 NOAA lidar data and the 2017 multibeam data was performed to quantify and map impacts to seafloor elevations and to determine elevation and volume change statistics for nine habitat types found at Crocker Reef, FL. Data were collected under Florida Keys National Marine Sanctuary permit FKNMS-2016-068.

Bird density and marine mammal counts based on 3000 meter bins in southern California, 1999-2002

Tracklines and associated observations were mapped and analyzed using ArcMap (ESRI, Redlands, CA). GPS data were recorded in NAD27 map datum and projected to an USGS Albers Equal Area Conic map projection for presentation and subsequent density analyses. Concatenated GPS and observation data were then used to generate point and line coverages in ArcMap (ESRI, Redlands, CA). We designed a custom analytic tool using ArcMap Model Builder that allows for the construction and export of user-specified and effort-adjusted spatial binning of species observations along continuous trackines. For the purposes of this report, we calculated seabird density estimates and marine mammal counts along continuous 3.0-kilometer and 7.7-kilometer trackline segments (i.e., 3.0 kilometer and 7.7 kilometer bins). Therefore, marine bird densities (at 3-kilometer scale, for example) are based on a composite strip area ranging from 0.15 per kilometer squared (one observer on effort) to 0.30 per kilometer squared (two observers on effort). We made no effort to adjust densities such that they would be proportional to variations in the area of buffered transect strip bin (i.e., weighted offset variable).

Model Archive Data for Suspended-Sediment Regression at Station 07048550, West Fork White River East of Fayetteville, AR

Data from an optical turbidity sensor deployed at the stream station were recorded at 15-minute intervals by a data logger and uploaded every hour to the USGS database (Anderson, 2005; Wagner, 2006). Suspended-sediment samples were collected using equal width increments or grab sampling techniques (Edwards, 1999). The use of an optical sensor to continuously monitor turbidity provided an accurate estimate of sediment fluctuations without the collection and analysis costs associated with intensive sampling (OSW policy 2016.07; Rasmussen et al., 2009). Turbidity was used as a surrogate for suspended-sediment concentration (SSC), which is a measure of sedimentation and siltation. Regression models were developed between SSC and turbidity using turbidity data from the optical sensor and  the SSC data collected from the suspended-sediment samples.
For the West Fork of White River East of Fayetteville instantaneous turbidity measurements began on October 11, 2014 and ranged from 0.3 to 1480 Formazin Nephelometric Units (FNU). A total of 64 suspended-sediment samples were collected and ranged from 2 to 1780 milligrams per liter (mg/L) across a range of streamflow from 0.71 to 7770 cubic feet per second (cfs). There were 50 suspended-sediment samples used in the final model after removing quality assurance/quality control samples, samples corresponding with gaps in turbidity data, samples associated with sampling/fouling errors, and extraneous samples from the same storm event which would result in overfitting of the model.

Archive of Single-Beam Bathymetry Data Collected from Select Areas in Weeks Bay and Weeks Bayou, Southwest Louisiana, January 2013

A team of scientists from the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center (SPCMSC), collected 92-line-kilometers (km) of dual-frequency single-beam bathymetry data in the tidal creeks, bayous, and coastal areas near Weeks Bay, southwest Louisiana. Limited bathymetry data exist for these tidally- and meteorologically- influenced shallow-water estuarine environments. In order to reduce the present knowledge gap, the objectives of this study were to (1) develop methods for regional inland bathymetry mapping and monitoring, (2) test an inland bathymetry mapping system, in pilot locations, for the purpose of integrating multiple elevation (aerial and terrestrial lidar) and bathymetry datasets, (3) implement inland bathymetry mapping and monitoring in highly focused sites, and (4) evaluate changes in bathymetry and channel-fill sediment storage.
This report contains single-beam bathymetric data collected between January 14 and 18, 2013(USGS Field Activity Number 13CCT01).  Data were collected from the R/V Mako (5-m vessel) in water depths that ranged from &lt;1 m to 7.7 m. Locations of data collection ranged from open-bay systems to narrow inland tidal creeks.
Do not use these data for navigational purposes.

ADCP Data in Support of Water and Suspended-Sediment Flux Measurements at the Golden Gate, 2016-2017

Field observations of water and suspended-sediment fluxes at the Golden Gate were made over one ebb tide and one flood tide on three occasions: 1) 21-22 March 2016, following a large storm event that triggered the first flow into Yolo Bypass flood control structure since 2011; 2) 23 June of 2016, during a period of low freshwater inflow and 3) 27-28 February 2017, following several large storms of the wettest winter in northern California in recorded history. On each occasion, flux of water and suspended sediment were estimated using data from a boat-mounted acoustic Doppler current profiler. This instrument provided high-resolution velocity and acoustic backscatter (ABS) data at a cross-section (“transect”) near the estuary-ocean boundary, approximately 1 km landward (east) of the Golden Gate Bridge. Discrete water samples collected in situ were analyzed for suspended-sediment concentration (SSC) and related to ABS to allow quantification of sediment concentrations and fluxes.

Diurnal patterns of methane flux from a depressional, seasonal wetland

Data on diurnal variation in wetland methane flux were collected to 1) improve understanding of short-term, mechanistic drivers of methane flux, and 2) inform sampling protocols to achieve research objectives. An automated gas flux sampling system was used to measure methane flux every 2.5–4 hours for over 230 diel cycles over the course of three growing seasons (2013–2015). Data were collected from a seasonal, depressional wetland located in the Prairie Pothole Region of central North America. These data directly support the associated publication “Diurnal patterns of methane flux from a depressional, seasonal wetland: mechanisms and methodology” which is referenced within the Metadata.
