Temperature thresholds for black mangrove (Avicennia germinans) freeze damage, mortality, and recovery in North America: refining tipping points for range expansion in a warming climate

To advance understanding of mangrove range dynamics in eastern North America, there is a need to refine temperature thresholds for mangrove freeze damage, mortality, and recovery. Here, We integrated data from 38 sites spread across the mangrove range edge in the Gulf of Mexico and Atlantic coasts of the southeastern United States, including data from a regional collaborative network called the Mangrove Migration Network (https://www.usgs.gov/centers/wetland-and-aquatic-research-center-warc/science/mangrove-migration-network). In 2018, an extreme freeze event affected 60 percent of these sites, with minimum temperatures ranging from 0 to -7 degrees Celsius. We used temperature data and vegetation measurements from before and after the freeze to quantify temperature thresholds for leaf damage, mortality, and biomass recovery of the black mangrove (Avicennia germinans) — the most freeze-tolerant mangrove species in North America. Note that the temperature logger data presented here are the site-level mean nightly minimum temperatures obtained from plot-level means of the raw temperature data collected from the loggers. For additional information, see the associated publication (Osland et al. 2019).

Geochemical and isotopic compositions of stream sediment, parent rock, and nearshore sediment from southwest Puerto Rico, April 2017-June 2018

Geochemical and isotopic compositions were determined in stream sediment and parent rocks collected in April 2017 and June 2017 and in nearshore sediment collected bimonthly in sediment traps from May 2017 to June 2018 in the coastal zone and 12 drainages of southwest Puerto Rico: Rio Loco, Yauco, Guayanilla, Macana, Tallaboa, Matilde, Portugues, Bucana, Inabon, Jacaquas, Descalabrado, and Coamo. Geochemical compositional data include: a) total contents of major, minor, trace, and rare earth elements in the &lt;0.063 mm-diameter fraction of terrestrial (n=53) and nearshore sediment (n=63) and powdered rocks (n=19) analyzed by inductively coupled plasma optical emission spectroscopy (ICP-OES) and inductively coupled plasma mass spectroscopy (ICP-MS); b) major oxide contents of stream sediment (n=46) and rocks (n=19) determined by wavelength dispersive x-ray fluorescence spectrometry (WD-XRF); and c) total organic carbon and carbonate contents of stream (n=48) and nearshore (n=64) sediment determined coulometrically. Isotopic compositional data include: 1) strontium isotope ratios (87Sr/86Sr) determined by thermal ionization mass spectrometry in the &lt;0.063 mm-diameter fraction of select stream (n=50) and nearshore (n=40) sediment, and in all rocks; and 2) activities of the short-lived cosmogenic nuclides beryllium-7, cesium-137, and excess (unsupported) lead-210 determined by gamma spectrometry on bulk nearshore sediment (n=44). The percentage by weight of the &lt;0.063 mm-diameter sediment fraction (percent fines), the median grain size, and the silt to clay ratio are reported for stream (n=48) and nearshore (n=64) sediments. These data accompany Takesue, R.K., Sherman, C., Ramirez, N.I., Reyes, A.O., Cheriton, O.M., Rios, R.V., and Storlazzi, C.D., 2021, Land-based sediment sources and transport to southwest Puerto Rico coral reefs after Hurricane Maria, May 2017 to June 2018: Estuarine, Coastal and Shelf Science, v. 59, p. 107476, https://doi.org/10.1016/j.ecss.2021.107476.

Electrical Resistivity Tomography Data at Edwards Air Force Research Laboratory, Antelope Valley, California, 2018

Electrical resistivity tomography (ERT) surveys were done northwest of the Air Force Research Laboratory (AFRL) at Edwards Air Force Base. ERT surveys were done at four locations in May through June of 2018 to refine the understanding of the bedrock-alluvial aquifer transition zone downgradient from the AFRL. The ERT technique injects direct-current electricity with known voltage and current into the earth using a series of electrodes and measures the resulting resistivity. This technique is generally limited to investigations of aquifer properties less than 100 meters below land surface. Data from other geophysical techniques co-located with the ERT data, including time-domain electromagnetics and horizontal-to-vertical spectral ratio passive seismic, are made available in other child pages within this data release: https://doi.org/10.5066/P9ZGZTA4. This page contains the ERT data, spatial information for the ERT transects, and preliminary processed ERT data.

Ground-Based Time-Domain Electromagnetic Data Collected at Edwards Air Force Research Laboratory, Antelope Valley, California, 2018

Time-domain electromagnetic (TEM) surveys were done northwest of the Air Force Research Laboratory (AFRL) at Edwards Air Force Base. TEM surveys were done at 33 locations between May and October 2018 to refine the understanding of the bedrock-alluvial aquifer transition zone downgradient from the AFRL. TEM surveys (also called transient electromagnetic surveys) provide 1D resistivity soundings of the subsurface, which can be related to lithology and hydrogeology. In the TEM method, electrical current is cycled through a transmitter loop (Tx) wire, which in turn produces a primary magnetic field. When the current is abruptly terminated, a secondary magnetic field is induced in the earth, and it moves downward and outward as the induced current decays with time. The decay is controlled by the resistivity of the earth. A receiver (Rx) at the center of the Tx loop measures the secondary magnetic field as a function of time (dB/dt). Decaying voltage measurements at the receiver are converted to apparent resistivity, which can be inverted to recover the depth-dependent vertical resistivity structure of the earth below the receiver location. Other geophysical techniques, including electrical resistivity tomography and horizontal-to-vertical spectral ratio passive seismic, co-located with the TEM data are made available in other child pages within this data release: https://doi.org/10.5066/P9ZGZTA4. This page contains the TEM data, spatial information for the TEM surveys, and preliminary processed TEM data.

Permafrost Mapping in Two Wetland Systems North of the Tanana River in Interior Alaska 2014, Survey Information

Surface-based 2D electrical resistivity tomography (ERT) surveys were used to investigate the distribution of permafrost at wetland sites on the alluvial plain north of the Tanana River, 20 km southwest of Fairbanks, Alaska, in June and September 2014.  The sites contained habitat types characteristic of interior Alaska, including thermokarst bog, forested permafrost plateau, and a rich fen.  These habitats range from treed to open and vary in groundcover vegetation and peat thickness. Individual surveys used a cable with 56 electrodes at 2-m spacing. At a fen site, ERT surveys were performed across a mixed spruce forest area across a vegetation gradient into an open fen area. At a bog site, surveys were performed across a thermokarst bog area bordered by spruce forest and forested permafrost plateau. Some surveys partly overlap in coverage within a season, and some surveys were repeated between seasons.  Different electrode array types, including dipole-dipole, extended dipole-dipole, and Wenner-Schlumberger, were compared at some sites. The metadata here specifically describe the timing, location, and array types associated with the ERT surveys.

Data on Factors Affecting Spatial and Temporal Variations of Annual Summer Median Water Yields in Southwestern Michigan, 1945-2015

Median summer water yields and resultant flows are used in Michigan to regulate large water withdrawals to help prevent negative effects on characteristic fish populations. Large water withdrawals commonly are associated with irrigation in rural areas. In an earlier statewide report, an index-flow statistic for the period of record, defined as the median flow during the summer month of lowest flow, was used to characterize median summer flows and associated water yields. In this report, the annual series of median summer water yields for the period July 1 through September 30 within the period of record is used to characterize median summer water yields. For 27 streamgages included in both reports, the average index water yield was at the 37th percentile of the distribution of median summer water yields. In contrast to an index statistic, an annual time series provides a basis for detecting trends in median summer water yields and for determining basin, climatic, and irrigation factors affecting spatial and temporal variations in summer water yields.  
Daily flow data from 40 selected U.S. Geological Survey streamgages in southwestern Michigan were used in this analysis. Two mixed models were identified to estimate median summer water yields based on fixed basin characteristics and temporally varying climatic factors for 1945-2015. No irrigation data were available prior to 1970, so no irrigation variables were included in the mixed models for 1945-2015. Then, two mixed models were developed for 1970-2015, a period in which a partial annual series of county-level irrigation data also were available. One of the 1970-2015 mixed models provides a basis for estimating median summer water yields at sites in southwestern Michigan using an estimated trend component, and selected basin, climatic, and irrigation factors. Re-estimation of model parameters in this mixed model with more spatially precise information on irrigation withdrawals may improve model accuracy.

Surface geophysics investigations at Edwards Air Force Research Laboratory, Antelope Valley, California, 2018

The Air Force Research Laboratory (AFRL) is about 7 kilometers southwest of Boron, California, and covers 320 square kilometers of Edwards Air Force Base. The AFRL consists of 12 facilities for testing full-size rocket engines, engine components, and liquid and solid propellants. The historical release of contaminants from rocket test stands, evaporation ponds, burn pits, catch basins, and leaking waste-collection tanks has contaminated groundwater in the AFRL. Groundwater aquifers near the AFRL are mostly restricted to fractured granitic bedrock, but previous studies indicate that groundwater and associated contaminants have moved into alluvium to the north and northwest. The U.S. Geological Survey (USGS) and the U.S. Air Force entered into a cooperative agreement to refine the understanding of the bedrock-alluvial aquifer transition zone downgradient from the AFRL. As part of that effort, surface geophysical data were collected to: (1) assess changes in the depth to bedrock with increasing distance from the AFRL; (2) to provide information on shallow geologic structures near the AFRL; and (3) to assess the presence of any faults that could present partial barriers to groundwater flow. The surface geophysical methods collected northwest of the AFRL in 2018 were electrical resistivity tomography (ERT), horizontal-to-vertical spectral ratio (HVSR) passive seismic, and time-domain electromagnetic (TEM).

Spatially Explicit Modeling of Annual and Seasonal Habitat for Greater Sage-Grouse (Centrocercus urophasianus) in Northeastern California

Successful adaptive management hinges largely upon integrating new and improved sources of information as they become available. Updating management tools for greater sage-grouse (Centrocercus urophasianus, hereafter referred to as “sage-grouse”) populations, which are indicators for the large-scale health of sagebrush (Artemisia spp.) ecosystems in the Great Basin of North America, provide a timely example for this tenet. Recently developed spatially-explicit habitat maps derived from empirical data played a key role in the conservation of this species facing listing under the Endangered Species Act. The spatial data provided herein apply resource selection function parameters that informed published maps of seasonal and annual habitat suitability and management areas for sage-grouse across combined population management units in Nevada and northeastern California as identified by the Nevada Department of Wildlife (Coates et al. 2016), to a previously unmapped area of northeastern California spanning 1,169,765 hectares. These data can be mosaicked or merged by users within a geographic information system with previously published mapping products from Coates et al. (2016) to make a seamless product that extends across the extent of known sage-grouse range in northeastern California. Please refer to Coates et. al. (2016) for further details on methodology.
