Farmers in parts of the western United States who rely on snowmelt to help irrigate their crops will be among the hardest hit in the world by climate change, a new study reveals.In a paper published i...
Climate change scientists warn that the continued burning of fossil fuels is likely to cause major disruptions to the global climate system leading to more extreme weather, sea level rise, and biodive...
Background: Total-body iron stores (TBI), which are calculated from serum ferritin and soluble transferrin receptor concentrations, can be used to assess the iron status of populations in the United S...
Background: In the literature, it has been suggested that there are race-ethnic disparities in what Americans eat. In addition, some studies have shown that residents of African American and low-incom...
The vast majority of infant formulas in the United States contain the long-chain polyunsaturated fatty acids (PUFAs) docosahexaenoic acid (22:6n–3) and arachidonic acid (20:4n–6), which were first per...
In spite of recent economic growth, India is a country with serious deficits in its power sector. Four hundred million Indians lack access to electricity, blackouts have become front-page news, and...
The Emission Scenario Projection (ESP) method produces future-year air pollutant emissions for mesoscale air quality modeling applications. We present ESP v2.0, which expands upon ESP v1.0 by spati...
More than a decade ago, the U.S. approach to research on harmful algal blooms (HABs) was uncoordinated and modest in scale. Research groups were few and their work was piecemeal and constrained by sma...
If nothing else, research in deep-sea environments teaches us how little we know about such important and productive habitats. The relatively recent discovery of hydrothermal-vent and cold-seep ecosys...
Terrestrial inputs largely govern nutrient delivery to the coastal ocean, and subsequent processes transform these nutrients in the land-ocean transition zone. Here, we describe spatial and temporal p...
Reconstructions of Holocene relative sea level (RSL) have valuable applications in a number of topics within the Earth sciences, including calibrating and constraining geophysical models of Earth's rh...
ABSTRACT Dustin Graves ASSESSING THE ROLE OF GEOLOGIC SETTING ON THE HYDROLOGY AND GROUND WATER GEOCHEMISTRY OF FENS IN THE GLACIATED MIDWESTERN UNITED STATES A water quality investigation of se...
Background: Marked increases in mean body mass index (BMI) and prevalence of obesity and overweight in the United States are well known. However, whether these average increases were accompanied by ch...
A semi-parametric PAR diffuse radiation model was developed using commonly measured climatic variables from 108 site-years of data from 17 AmeriFlux sites. The model has a logistic form and improve...
