Management status and policy direction of submerged marine debris for improvement of port environment in Korea

open access: yesOpen Geosciences, 2022
As the issue of marine waste is emerging around the world, it is urgent to come up with measures to manage marine waste. This study examined the status of the collection project of submerged marine debris (SMD) undertaken to improve the environment of ...

Metallicity of solar-type stars with debris discs and planets [PDF]

open access: yes, 2012
Around 16% of the solar-like stars in our neighbourhood show IR-excesses due to debris discs and a fraction of them are known to host planets. We aim to determine in a homogeneous way the metallicity of a sample of stars with known debris discs and ...

Microplastics in Invasive Freshwater Mussels (Dreissena sp.): Spatiotemporal Variation and Occurrence With Chemical Contaminants

open access: yesFrontiers in Marine Science, 2021
Invasive zebra and quagga mussels (Dreissena spp.) in the Great Lakes of North America are biomonitors for chemical contaminants, but are also exposed to microplastics (<5 mm).

Debris Thickness of Glaciers in the Everest Area (Nepal Himalaya) Derived from Satellite Imagery Using a Nonlinear Energy Balance Model [PDF]

open access: yes, 2014
Debris thickness is an important characteristic of debris-covered glaciers in the Everest region of the Himalayas. The debris thickness controls the melt rates of the glaciers, which has large implications for hydrologic models, the glaciers' response to

Including debris cover effects in a distributed model of glacier ablation [PDF]

open access: yes, 2012
Distributed glacier melt models generally assume that the glacier surface consists of bare exposed ice and snow. In reality, many glaciers are wholly or partially covered in layers of debris that tend to suppress ablation rates.

Estimation of magnitudes of debris flows in selected torrential watersheds in Slovenia [PDF]

open access: yes, 2006
In this paper the application of different methods for estimation of magnitudes of rainfall-induced debris flows in 18 torrents in the Upper Sava River valley, NW Slovenia, and in 2 torrents in Pohorje, N Slovenia is described. Additional verification of

Human Population Density is a Poor Predictor of Debris in the Environment

open access: yesFrontiers in Environmental Science, 2021
There have been a variety of attempts to model and quantify the amount of land-based waste entering the world’s oceans, most of which rely heavily on global estimates of population density as the key driving factor.
