Herein we report on the abundance and composition of floating marine debris (FMD) in coastal waters of the SE-Pacific (off the Chilean coast) during the austral summer 2002. The observed FMD consisted mainly of plastic material (86.9%). Densities of FMD were highest between 20 degrees S and 40 degrees S, corresponding to the main concentrations of human population and activities. Low densities ...

A better knowledge of the physiological basis of salinity tolerance is essential to understanding the ecology and evolutionary history of organisms that have colonized inland saline waters. Coleoptera are amongst the most diverse macroinvertebrates in inland waters, including saline habitats; however, the osmoregulatory strategies they employ to deal with osmotic stress remain unexplored. Survi...

Samothraki is a northern Aegean island with poorly studied inland waters. River features show a high degree of naturalness; lotic, lentic and riparian conditions exhibit significant perennial flows with waterfalls, pools and ancient riparian woodlands. In this study, we document surface and ground water quality status based on recent field observations, data collection and analyses. The island ...

To develop the models for chlorophyll (CHL) estimation, the nature of a peak near 700 nm on the reflectance spectrum of water should be investigated. Simultaneous measurements of the reflectance spectra from 400 to 750 nm and relevant water quality constituent concentrations were carried out. A shift of the peak position and an increase of the peak magnitude, when chlorophyll concentration incr...

Since the launch of ENVISAT satellite in 2002, the Radar Altimetry Mission provides systematic altimeter observations of the Earth surface. The ENVISAT Geophysical Data Records products contain, over all type of surfaces, altimeter ranges derived from four specialized retrackers: Ocean, Ice-1, Ice-2 and Sea-Ice retracker. Among the different goals of the ENVISAT Mission, one directly concerns l...

Figure 1. Approximate distribution of harbor porpoise in the U.S. Pacific Northwest (shaded area). Stock boundaries separating the stocks are shown. STOCK DEFINITION AND GEOGRAPHIC RANGE In the eastern North Pacific Ocean, the harbor porpoise ranges from Point Barrow, along the Alaskan coast, and down the west coast of North America to Point Conception, California (Gaskin 1984). Harbor porpoise...
