AndreaBozzo/ceres-open-data-index huggingface dataset:
Evapotranspiration (ET) at Blue Cypress marsh site, daily data, Indian River County, Florida, June 1, 1995 – October 20, 2014

The data consists of daily evapotranspiration (ET) measurements/estimates for the time period June 1, 1995 to October 2014. These data are derived from (1) measurements of actual ET conducted at the USGS Blue Cypress marsh station (USGS station number 274143080424100) and (2) estimates of actual ET inferred from statistical regressions between the measurements of actual ET and potential ET. The station is located at a nearly flat wetlands site (27 degrees 41 minutes 43 seconds North / 080 degrees 42 minutes 41 seconds West) within the Blue Cypress Marsh Conservation Area, Indian River County, Florida. The dominant plant cover at the study site is sawgrass (Cladium jamaicense), with secondary amounts of other wetland plant species. Sawgrass height generally varies from 1.8 to 2.4 meters. The canopy can be temporarily removed through fire, followed by rapid re-growth. The soils at the site are peats. The water-table generally is above land surface but can be greater than a meter below land surface during droughts. Actual ET measurements derived using the eddy-covariance method are available for January 1, 2000 to September 1, 2005; and December 11, 2009 to October 20, 2014. The contribution of the present Data Release is dissemination of a dataset of actual ET estimates for a period prior to the first period of actual ET measurements (June 1, 1995 to December 31, 1999) and for the time interval between the two periods of actual ET measurement (September 2, 2005 to December 10, 2009). Estimates of actual ET during periods of missing actual ET measurements were obtained using regression-determined, monthly vegetation coefficient multipliers applied to potential ET data. The source of potential ET data was an existing Statewide database developed through an assimilation of satellite- and field-based meterological data. A seamless time series of measured and estimated actual ET for the period June 1, 1999 to December 10, 2014 is provided in this Data Release. Although the actual ET estimator performs relatively well (r-squared values of 0.85 and 0.95 for daily and monthly periods, respectively) in reproducing measured data, it should be noted that this degree of accuracy is not assured for non-measured time periods.

Tool-use frequency by individual sea otters in California

Sea otters are well-known tool users, employing objects such as rocks or shells to break open invertebrate prey. We used a series of generalized linear mixed effect models (GLMEs) to examine observational data on prey capture and tool use from 211 tagged individuals from five geographically defined study areas throughout the sea otter’s range in California. Our best supported model was able to explain 75% of the variation in the frequency of tool-use by individual sea otters with only ecological and demographic variables. In one study area, where sea otter food resources were abundant, all individuals had similar diets focusing on preferred prey items and used tools at low to moderate frequencies (4-38% of prey captures). In the remaining areas, where sea otters were food-limited, individuals specialized on different subsets of the available prey and had a wider range of average tool-use frequency (0-98% of prey captures). The prevalence of difficult-to-access prey in individual diets was a major predictor of tool use, and increased the likelihood of using tools on prey that were not difficult to access as well. Age, sex, and feeding habitat also contributed to the probability of tool use, but to a smaller extent. We developed a conceptual model illustrating how food abundance, the prevalence of difficult-to-access prey, and individual diet specialization interacted to determine the likelihood that individual sea otters would use tools and considered the model’s relevance to other tool-using species.
The dataset is a csv file of tool-use frequency based on observed foraging behaviors of tagged sea otters in California. Foraging data was collected opportunistically on each individual over time (typically 1-3 years). For each successful foraging dive, observers recorded the type of habitat the sea otter was using, the prey type consumed, and whether a tool use used to open the prey item. These observations are summarized as the percent prey captures with tool-use observed for each grouping of prey type, habitat type, and individual sea otter. Dataset also includes the age, sex, and general location of each individual.

Evaluating population responses of Greater sage-grouse to variation in public grazing records at broad scales

In 'Broad-scale analysis of greater sage-grouse population trends in response to grazing records in Wyoming, USA (2004-2014)', we provide data and R code necessary for analyzing state-space models for male greater sage-grouse (Centrocercus urophasianus) populations in response to grazing level, timing, and NDVI in Wyoming, USA, and then to compare models with 10-fold cross validation scores (Monroe et al. 2017). In 'Analysis of Land Health Standard failure among allotments in Wyoming, USA (2001-2009)', we provide data and R code necessary for logistic regression analyzing effects of grazing level and timing on the probability of an allotment failing one or more Land Health Standard (LHS) the previous year (Monroe et al. 2017). Relative predictive ability of models are then compared with a 10-fold cross-validation score. In 'Data to evaluate sensitivity of model results to scale and allotment overlap threshold', we provide data used to evaluate the sensitivity of our results to our choice of scale (6.44 km around lek sites) and the overlap threshold for allotments with grazing data (&gt;75%).

Digital Database and Maps of Quaternary Deposits in East and Central Siberia

This digital database is the product of collaboration between the U.S. Geological Survey, the  Alfred Wegener Institute for Polar and Marine Research Potsdam, Foothill College GeoSpatial Technology Certificate Program, and the Geophysical Institute at the University of Alaska. The primary goal for creating this digital database is to enhance current estimates of organic carbon stored in deep permafrost, in particular Late Pleistocene syngenetic ice-rich loess permafrost deposits, called Yedoma.  This deposit is vulnerable to thermokarst and erosion due to natural and anthropogenic disturbances.
The original paper maps were issued by the Department of Natural Resources of the Russian Federation or its predecessor the Department of Geology of the Soviet Union and have their foundation in decades of geological field and remote sensing work and mapping at scales 1:50,000 to 1:500,000 by Russian geologists and cartographers in the respective regions. Eleven paper maps were scanned and digitized to record the geology unit boundaries, genetic type and clast size of each geologic unit, and borehole and outcrop locations. We also calculated area in km2, perimeter in km for each polygon. These attributes were used in support of (Grosse and others, 2013) which focused on extracting geologic units interpreted as Yedoma, based on lithology, ground ice conditions, geochronology, geomorphologic, and spatial association.

Disentangling the effects of low pH and metal mixture toxicity on macroinvertebrate diversity: data sets

This dataset is comprised of water quality data and benthic macroinvertebrate data collected from basins in Colorado, USA, and Finland. The data includes ancillary water quality characteristics but also a suite of trace metals observed at each site. Also included are modeled outputs that characterize the bioavailability of each trace metal to a biotic ligand. These data were used to explore the importance of metal toxicity and pH as stressors on benthic macroinvertebrates characterized as the number of unique Ephemeroptera + Plecoptera + Trichoptera genera observed at each site. An interpretive summary of the work follows.
One of the primary goals of biological assessment of rivers is to identify whether contaminants or other stressors limit the ecological potential of running waters. Quantitative relationships between species richness and environmental gradients are useful to better understand biodiversity patterns.
Many studies have focused on the effects of pH and high metals concentration on freshwater macroinvertebrate community but, due to data limitation and the lack of tools, the ecological effects of metals mixture in streams are less studied and still unclear.
We address an old question: is it the low pH or the metals that are deleterious for stream ecosystems? With new tools, we can achieve improved understanding of the true importance of the two stressors.
Our study quantified the limiting effects of pH and chronic metal toxicity for macroinvertebrate community richness. We verified that current environmental quality standards for metals are protective of aquatic biodiversity and proved that pH has a direct limiting effect on richness and it not acts only via modifying the availability and the toxicity of metals.
These questions were applied to a dataset spanning two continents and diversity of geologies and ecosystems providing a broad basis for understanding how physico-chemical conditions limit global freshwater biodiversity.

Vermilion River Flood Map Files

A slow-moving area of low pressure and a high amount of atmospheric moisture produced heavy rainfall across Louisiana and southwest Mississippi in August 2016. Over 31 inches of rain was reported in Watson, 30 miles northeast of Baton Rouge, over the duration of the event. The result was major flooding that occurred in the southern portions of Louisiana and included areas surrounding Baton Rouge and Lafayette along rivers such as the Amite, Comite, Tangipahoa, Tickfaw, Vermilion, and Mermentau. The U.S. Geological Survey (USGS) Lower Mississippi-Gulf Water Science Center operates many continuous, streamflow-gaging stations in the impacted area.  Peak streamflows of record were measured at 10 locations, and seven other locations experienced peak streamflows ranking in the top 5 for the duration of the period of record. In August 2016, USGS personnel  made fifty streamflow measurements at 21 locations on streams in Louisiana. Many of those streamflow measurements were made for the purpose of verifying the accuracy of the stage-streamflow relation at the associated gaging station. USGS personnel also recovered and documented 590 high-water marks after the storm event by noting the location and height of the water above land surface. Many of these high water marks were used to create twelve flood-inundation maps for selected communities of Louisiana that experienced flooding in August 2016. This data release provides the actual flood-depth measurements made in selected river basins of Louisiana that were used to produce the flood-inundation maps published in the companion product (Watson and others, 2017).
