Water level data (15-min frequency) from 18 instrumented playas in the Jornada Basin, southern New Mexico, USA, from 2016-2022
This dataset contains water level data collected at 18 playas starting in June 2016 for a long-term study of playa inundation at the Jornada Basin LTER site in southern New Mexico, U.S.A. Playas are located throughout the Jornada Basin and are instrumented with dataloggers and attached pressure transducers located at the lowest point of each playa. Instantaneous measurements of surface water level are made every 15 minutes. Data are processed to flag errors and identify periods of playa inundation (floods). This is an ongoing study and the dataset will be updated yearly.

FIG, 1. John William Daly (1933–2008) on the upper Río San Juan. This paper is dedicated to John Daly, our late friend and colleague, who helped collect three of the new species here described. In addition to his globally acclaimed discoveries in chemistry and pharmacology, John was an accomplished field herpetologist who contributed importantly to the systematics and natural history of dendrobatoid frogs (see Grant et al., 2006; Myers, 2009). This photograph shows John at age 37, with the upper Río San Juan behind him and branches overhead of a madroño tree (probably Garcinia magnifolia, syn. Rheedia chocoensis, Clusiaceae). When in South America, John was never far from a dendrobatid frog—this time, in the tree above his head, a tiny, undescribed semiarboreal species (also collected and later named "Dendrobates fuguritus" by our colleague Philip Silverstone). Other dendrobatids found nearby included Phyllobates aurotaenia (Boulenger, 1913), which was then being used for poisoning blowgun darts, and also the nontoxic species that we name Silverstoneia dalyi herein.

Soil carbon, soil nitrogen, and geometry of 30 playas and their catchment areas at the Jornada Basin LTER site in 2012
This data package contains soil carbon and nitrogen data at a range of soil depths from 30 ephemerally-flooded desert wetlands, or playas, in the Jornada Basin of southern New Mexico, USA. We conducted this study to assess how catchment biophysical variables control soil organic carbon and nitrogen in playas and how playas function differently than upland ecosystems. We chose 30 playas from across this Chihuahuan Desert Basin and collected 36 soil samples from four depths and nine locations. Soil cores samples were taken along two perpendicular transect lines to account for a topographic gradient from the edge of the playa to the center of the playa. At each of the nine locations, one sample was collected at four depths (0–10 cm, 10–30 cm, 30–60 cm, 60–100 cm). We measured soil organic carbon and total nitrogen concentrations in these soils using elemental combustion analysis. Using bulk density measurements for each depth range (m), we converted each soil measurement (g/g) to calculate concentrations of organic carbon and nitrogen per unit area (g/m^2) within the depth-ranges sampled. Data on the geometry of the playas and their associated catchments is also provided. This study is complete. For further information, refer to: McKenna, Owen P., and Osvaldo E. Sala.

Soil water and chloride concentration profiles in 20 playas at the Jornada Basin LTER site in 2014
This data package contains soil water and chloride content data from cores collected in 20 playas in the Jornada Basin of southern New Mexico, USA. The objectives of this work were to assess the rates and controls of groundwater recharge through playas in the Southwestern USA. The twenty playas were cored to 5 meter depth and we used the chloride mass balance (CMB) approach to empirically estimate groundwater recharge beneath playa surfaces. The measured variables are gravimetric soil moisture (kg water/kg soil), soil bulk density (kg/m3), volumetric water content (m3/m3), and porewater chloride (mg/L). All data were taken from playa ecosystems. All measurements were taken in June 2014. This study is complete. For further information, refer to: McKenna, Owen P., and Osvaldo E. Sala. "Groundwater recharge in desert playas: current rates and future effects of climate change." Environmental Research Letters 13, no. 1 (2018): 014025. https://doi.org/10.1088/1748-9326/aa9eb6

Sewage structure, Playa San Blas
This precast concrete element is used to bury outlets under the sand (pipes that expel wastewater into the sea). Its function is to protect the pipe against storms or impacts. The reasons why this "issue" was in the center of what should have been a sebadal patch are unknown, we consider the loss of the piece during transport as a hypothesis. Depth: 10 meters Number of photos: 110 photos Working conditions: good, without currents and visibility 15 meters. Dimensions: 2 meters wide by 1.5 long by 1 meter high.
