Spatial and temporal trends in surface water and sediment contamination in the Laurentian Great Lakes.
Data from recent sediment and surface water surveys have been collated and mapped to illustrate the spatial distribution of contaminants across the entire Great Lakes basin. Information fromExpand

Spatial and long-term temporal assessment of Lake Ontario water clarity, nutrients, chlorophyll a, and zooplankton
Secchi depth, total phosphorus, soluble reactive phosphorus, silica, chlorophyll a, and zooplankton (density, biomass, and average size) were sampled as part of a lake-wide, seasonal (spring, summer,Expand

Cooperative Science and Monitoring Initiative (CSMI) for the Great Lakes — Lake Ontario 2008
Abstract The Cooperative Science and Monitoring Initiative (CSMI) was created as the result of a need to coordinate science in support of management of the Great Lakes. The process includes enhancedExpand

Time-resolved pump-probe experiments beyond the jitter limitations at FLASH
Using a noninvasive, electro-optically based electron bunch arrival time measurement at FLASH (free electron laser in Hamburg) the temporal resolution of two-color pump-probe experiments has beenExpand

Spatial distributions and temporal trends in pollutants in the Great Lakes 1968-2008
The Great Lakes have been the focus of intensive long-term research and monitoring programmes for the past 40 years. Spatial distributions and temporal trends have been determined for a range ofExpand

Two-photon excitation and relaxation of the 3d-4d resonance in atomic Kr.
Two-photon excitation of a single-photon forbidden Auger resonance has been observed and investigated using the intense extreme ultraviolet radiation from the free electron laser in Hamburg. At theExpand

Two-photon inner-shell ionization in the extreme ultraviolet.
We have observed the simultaneous inner-shell absorption of two extreme-ultraviolet photons by a Xe atom in an experiment performed at the short-wavelength free electron laser facility FLASH.Expand

Polarization control in two-color above-threshold ionization of atomic helium.
Two-color multiphoton ionization of atomic helium was investigated by combining extreme ultraviolet (XUV) radiation from the Free Electron Laser in Hamburg with an intense synchronized optical laser.Expand

Femtosecond X-ray Pulse Length Characterization at the LCLS Free Electron Laser
Two-color, single-shot time-of-flight electron spectroscopy of atomic neon was employed at the Linear Coherent Light Source (LCLS) to measure the laser-assisted Auger decay in the X-ray regime. ThisExpand
