The Use of Solute-transport Methods to Estimate Time-varying Nitrogen Loading Rates to the Peconic Estuary Resulting from Wastewater and Fertilizer Inputs to Groundwater in Suffolk County, New York (Peconic Solute Transport)

Problem The Peconic Estuary of eastern Long Island, New York, is undergoing development as the region transitions from a rural area dependent on agriculture and tourism to a suburban one with a larger year-round population. The glacial and coastal-plain sediments underlying Long Island comprise a sole-source aquifer system that supplies the region’s communities with potable water. The area...

Sentinel Monitoring of Groundwater for Contaminants of Emerging Concern to Provide Advanced Warning for Supply Wells on Long Island, New York

Problem The groundwater supply of Nassau and Suffolk Counties is prone to contamination from past and current land uses, including practices related to agriculture, industry, and residential development, because the soils and underlying sediments are generally composed of sandy, permeable materials that allow contaminants to move readily from the land surface into the groundwater below. Of...

Modeling summer month hydrological drought probabilities in the United States using antecedent flow conditions

Climate change raises concern that risks of hydrological drought may be increasing. We estimate hydrological drought probabilities for rivers and streams in the United States (U.S.) using maximum likelihood logistic regression (MLLR). Streamflow data from winter months are used to estimate the chance of hydrological drought during summer months. Daily streamflow data collected from 9,144...

Water Use - Ohio Kentucky Indiana

The USGS National Water-Use Information Program collects data about the quantities of water withdrawn for specific uses: public supply, domestic, industrial, mining, thermoelectric power, irrigation, livestock, and aquaculture. On a broader scale, we research how humans interact with the hydrologic cycle throuugh water withdrawal, water delivery, consumptive use, return flows, wastewater reuse...

Monitoring High-Priority Stream Crossings Along Proposed Natural Gas Pipeline Routes

The U.S. Geological Survey (USGS), in cooperation with the Virginia Department of Environmental Quality (DEQ), is monitoring the water quality of multiple high-priority streams where natural gas pipeline crossings have been proposed. The purpose of the monitoring effort is to collect baseline water-quality data and, if the pipeline construction is approved, to monitor water quality in these...

Long-Term Response Monitoring of Suspended-Sediment Transport Characteristics on the Patapsco River near Ellicott City, Maryland, in Response to the Removal of Simkins Dam, 2010-present

For over 100 years, the Patapsco River has been impacted by the presence of several dams that were designed and built at the beginning of the 20th century. The objective of the project is to monitor suspended-sediment transport resulting from the removal of Simkins Dam on the lower Patapsco River in November 2010. The role of USGS in the project includes operation and maintenance of 3 stream...

Azimuthal seismic anisotropy of 70 Ma Pacific‐plate upper mantle

Plate formation and evolution processes are predicted to generate upper mantle seismic anisotropy and negative vertical velocity gradients in oceanic lithosphere. However, predictions for upper mantle seismic velocity structure do not fully agree with the results of seismic experiments. The strength of anisotropy observed in the upper mantle...

Water salinity and inundation control soil carbon decomposition during salt marsh restoration: An incubation experiment

Coastal wetlands are a significant carbon (C) sink since they store carbon in anoxic soils. This ecosystem service is impacted by hydrologic alteration and management of these coastal habitats. Efforts to restore tidal flow to former salt marshes have increased in recent decades and are generally associated with alteration of water inundation...

Size-specific apparent survival rate estimates of white sharks using mark-recapture models

For species that exist at low abundance or are otherwise difficult to study, it is challenging to estimate vital rates such as survival and fecundity and common to assume that survival rates are constant across ages and sexes. Population assessments based on overly simplistic vital rates can lead to erroneous conclusions. We estimated sex and...

Enhancement of primary production during drought in a temperate watershed is greater in larger rivers than headwater streams

Drought is common in rivers, yet how this disturbance regulates metabolic activity across network scales is largely unknown. Drought often lowers gross primary production (GPP) and ecosystem respiration (ER) in small headwaters but by contrast can enhance GPP and cause algal blooms in downstream estuaries. We estimated ecosystem metabolism across...

Explaining harvests of wild-harvested herbaceous plants: American ginseng as a case study

Wild-harvested plants face increasing demand globally. As in many fisheries, monitoring the effect of harvesting on the size and trajectory of resource stocks presents many challenges given often limited data from disparate sources. Here we analyze American ginseng (Panax quinquefolius L.) harvests from 18 states in the...

The missing dead: The lost role of animal remains in nutrient cycling in North American Rivers

While leaf litter, wood, and other plant remnants are known to play a central role in lotic ecosystems, animal remains (carcasses, bones, shells) have received less attention. We propose a simple classification scheme for animal remains in rivers based on origin (authochthonous vs. allochthonous) and frequency (pulsed vs continuous). We then...

The evolutionary consequences for seawater performance and its hormonal control when anadromous Atlantic salmon become landlocked

Populations of anadromous fish have become landlocked in relatively recent geological history (<14,000 years), but the evolutionary impacts of this altered lifecycle on traits underlying seawater performance have not been established. In order to examine the effects of relaxed selection on seawater traits, anadromous and landlocked Atlantic...

Paleocene–Eocene Thermal Maximum prolonged by fossil carbon oxidation

A hallmark of the rapid and massive release of carbon during the Palaeocene–Eocene Thermal Maximum is the global negative carbon isotope excursion. The delayed recovery of the carbon isotope excursion, however, indicates that CO2 inputs continued well after the initial rapid onset, although there is no consensus about the source of this...
