Seabirds from the poles: microplastics pollution sentinels

Frontiers in Marine Science, Journal Year: 2024, Volume and Issue: 11

Published: March 6, 2024

The Arctic and Antarctica represent two of the most inhospitable poorly investigated biomes in world. Although polar regions are still perceived as some pristine places existence, these remote no longer immune to anthropogenic pollution, particular, micro- nanoplastics. Seabirds, avian species feeding mainly at sea, indicators change environment an early study group ecological for plastic pollution. goal this bibliometric overview is evaluate international research trends on impacts microplastics (MPs) nanoplastics (NPs) seabirds inhabiting regions. A total least 13 seabird were reported have ingested MPs from 1983–2023. Overall, 1130 samples investigated, including stomach content, pouch guano, pellets.

Determination of equivalent cohesion for snow and ice samples in the cold laboratory of the Geography Faculty of MSU

BIO Web of Conferences, Journal Year: 2025, Volume and Issue: 173, P. 03002 - 03002

Published: Jan. 1, 2025

This paper examines the use of snow and ice as construction materials in polar regions, emphasizing their environmental benefits. Rapid climate change regions necessitates maintenance sustainable infrastructure, becomes a promising option due to its mechanical properties at low temperatures. Technologies such production blocks pipes for buildings thermal insulation are described. Snow compaction plays key role creation winterized roads runways, using ball stamp method control strength. The results showed an equivalent cohesion around 0.04, compacted 0.01–0.025.

Influence of metal structural heterogeneity in a sheet tube billet on forming mechanical properties and crack resistance of steel pipes for operation in the Arctic climate conditions

CIS Iron and Steel Review, Journal Year: 2024, Volume and Issue: 28, P. 69 - 74

Oil and gas main pipelines, which provide delivery of gaseous liquid raw materials from the Russian distant Arctic Sub-Arctic regions for processing at production facilities in central RF areas, remain base transportation system energy carriers.New pipeline systems are expanding far to north north-east mostly uninhabited territories with weakly developed transport infrastructure extremal operating conditionslow climatic temperatures increased corrosion activity mined materials.Analysis operation such conditions displayed enormous rise number accidents rejects pipelines comparison regions.Thus, metal structural heterogeneity a sheet tube billet, presented by its banding difference grain size as well presence large non-metallic inclusions, considered one key causes accidents.The results investigation effect inclusions state billet on mechanical properties, crack resistance basic heat-affected zones this research.The examined tubes used carriers minimal possible temperatures.
