The authors have been involved in numerous street cleaning research projects for over 30 years. This paper will give us a unique opportunity to highlight the historical use of street cleaning as a method for reducing stormwater pollutants, and will examine newly emerging street cleaning technologies. There have been many misconceptions concerning this potential stormwater management control. Th...

This paper presents an overview of fatigue testing systems in high-cycle regime for metals subjected to uniaxial and multiaxial random loadings. The different are critically discussed, highlighting advantages possible limitations. By identifying relevant features, the classified terms type machine (servo-hydraulic or shaker tables), specimen geometry applied constraints, number load acceleratio...

The Baltic and Black Seas are both brackish, that is to say both have salinities intermediate between freshwater and seawater. The coccolithophore Emiliania huxleyi is abundant in one, the Black Sea, but absent from the other, the Baltic Sea. Here we present summertime coccolithophore measurements confirming this difference, as well as data on the calcium carbonate saturation state of the Balti...

S U M M A R Y We have reprocessed ERS-1 radar altimeter waveforms using an algorithm designed to minimize sea surface slope error and decouple it from significant wave height (SWH) error. Standard waveform retracking estimates three parameters—arrival time, SWH and amplitude. We show that errors in retracked estimates of arrival time and SWH are inherently correlated because of the noise charac...

[1] SMOS (Soil Moisture and Ocean Salinity) is a European Space Agency mission that aims at generating global ocean salinity maps with an accuracy of 0.1 psu, at spatial and temporal resolution suitable for climatic studies. The satellite sensor is an L-band (1400–1427 MHz) aperture synthesis interferometric radiometer. Sea surface salinity (SSS) can be retrieved since the brightness temperatur...

The goal of this project is to develop a new capability for the chemical characterization of marine aerosols. This involves the development of an instrument to make quantitative, near real-time sodium concentration measurements on individual size-segregated marine aerosols. The development and deployment of a single particle sodium detector would allow us to measure the size distribution of sea...

It has been widely noted that sea ice retreats faster in summer than winter in the Northern Hemisphere, both in observations and in projections from state-of-the-art climate models. Explanations for why the wintertime sea ice cover should be less sensitive to global warming have been proposed. However, in the Southern Hemisphere sea ice retreats fastest in winter in climate model projections. H...

The transition from transient response to steady-state for a layered medium subjected to antiplane loadings is studied. The steady-state formula for a layered medium is derived and the solutions for a layered half-space are then expressed explicitly in the form of wave number integrals. The transient response solutions for a layered half-space are obtained by the convolution of time harmonic lo...
