Pesticides detected in surface waters and fish of the Red River of the North drainage basin Pesticides detected in surface waters and fish of the Red River of the North drainage basin
The Red River of the North drainage basin (herein referred to as Red River Basin) within the United States is a study unit under the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) program. The overall goals of this program, initiated to better define the status and trends of the Nation’s water quality, are to address regional and national water-quality issues in...

Tertiary structural evolution of the southern Rhodope metamorphic province: a fundamental revision Tertiary structural evolution of the southern Rhodope metamorphic province: a fundamental revision
The Rhodope province is conventionally interpreted as a continental fragment that was caught between Apulia and Europe and deformed and metamorphosed in the hinterland of the Hellenic collisional orogen. Geologic mapping in the Strymon Valley region of northeastern Greece augmented by new U-Pb and 40Ar/ 39Ar geochronologic data support an alternative view that the southwestern Rhodope...

A seabird monitoring program for the North Pacific A seabird monitoring program for the North Pacific
Seabird monitoring is the accumulation of time series data on any aspect of seabird distribution, abundance, demography, or behavior. Typical studies include annual or less frequent measures of numbers or productivity; less commonly, the focus is on marine habitat use, phenology, food habits, or survival. The key requirement is that observations are replicated over time and made with...
