An unphumed, but unique, experiment has given an in situ measurement of the strength of deforming subglacial till under the central region of a major valley glacier. We report on both planned and unplanned borehole investigations of the subglacial shear zone of Columbia Glacier, southeast Alaska. Basal samples, coring and down-hole water samples show that the fiord-filling lower reach of the •a...

Plastic debris litters marine and terrestrial habitats worldwide. It is ingested by numerous species of animals, causing deleterious physical effects. High concentrations of hydrophobic organic contaminants have also been measured on plastic debris collected from the environment, but the fate of these contaminants is poorly understood. Here, we examine the uptake and subsequent release of phena...

The distribution, abundance, and characteristics of neuston plastic in the North Pacific, Bering Sea, and Japan Sea were studied during the 4-year period 1985-88 at 203 neuston stations encompassing ca. 91,000 m2 of sampling. The highest total density of neuston plastic was 316,800 pieces/km2 at lat. 35"59'N, long. 152"OO'E in Transitional Water east of Japan. The highest total concentration of...

This study presents a large-scale monitoring of marine litter performed in the joint Norwegian–Russian ecosystem monitoring surveys in the period from 2010 to 2016 and contribute to documentation of the extent of marine litter in the Barents Sea. The distribution and abundance of marine litter were calculated by recordings of bycatch from the pelagic trawling in upper 60m, from bottom trawling ...

Abstract. Agricultural plastic covers made from polyethylene (PE) and polypropylene (PP) provide increased yields an improved crop quality. However, such are suspected of partially breaking down into smaller debris thereby contributing to soil pollution with microplastics. To scrutinize this, we randomly sampled 240 topsoil cores (0–5 cm) eight fields which were covered fleeces, perforated foil...

Marine debris is one of the global problems due to human activities. One biggest loads marine in city Jakarta, namely Pluit Emplacement. Emplacement a special location for managing with largest burden discharged from urban areas. This study analyses aquatic waste's generation or debris, composition, and recycling potential at The research process starts formulating problem, conducting literatur...
