Since 2000, however, the marine ecosystem has become unstable due to climate change, marine pollution and other factors, resulting in unstable catch volumes and otherwise affecting the lives of people working in fisheries-related jobs.
It also explores how organisms interact within their individual marine ecosystems, and discusses the impact of human activity on oceans, pollution, oceanic dead zones, and coral reefs.
For marine ecosystems, the possibility of effects on flora and fauna was limited to the shoreline area adjacent to the power station and the potential for effects over the long term was considered insignificant.
As the first MSC certified Chinese longline fishery, Liancheng now joins an elite group of fisheries working hard to protect our marine ecosystems and protecting seafood supplies for this and future generations.
The MSC program meets all the essential components of the GSSI benchmark, and a further 63 supplementary components relating to issues such as deep sea fishing, vulnerable marine ecosystems and data collection to demonstrate impact.
Changes in the ocean have impacted marine ecosystems and ecosystem services with regionally diverse outcomes, challenging their governance(high confidence).
DOM that is easily broken down will be recycled within the marine ecosystem, whereas refractory(difficult to break down) DOM, and the carbon it contains, will be locked away for thousands of years.
It's a huge step for Cambodia, because there was no formal protection for these coral reef habitats before… you risked overexploiting species. The marine ecosystem is a delicate balance.”.
This first expedition gave the decisive impetus to the entire Gombessa project, which is today composed of four missions dedicated to the study of the world's rarest and most untouched marine ecosystems.
During the assessment, the three principles of the MSC's fishery standard were evaluated in detail: the status of the fish stock, the impact of the fishery on the marine ecosystem and the management system overseeing the fishery.
By the end of the century, the acidification of the oceans is expected to exceed what the planet has experienced in the past 30 million years, which has sparked concerns for the stability of marine ecosystems.
According to a report jointly produced by the Food and Agriculture Organization(FAO) and the UN Environment Program(UNEP), fishing nets abandoned at sea remain in the marine ecosystem for hundreds of years.
As the earliest evidence of over-water gliding in vertebrates, the new discovery lends support to the hypothesis that the recovery of marine ecosystems after the end-Permian was more rapid than previously thought.".
Another special feature of the nuclear weapon, referred to at the hearings, is the damage caused by ionizing radiation to coniferous forests, crops, the food chain, livestock and the marine ecosystem.
Natural Resources and Ecosystem Services: Outline The Asia-Pacific region is blessed with great diversity and richness in natural resources, from biodiversity-rich tropical forests and wetlands, to fertile flood plains and deltas, to diverse freshwater and coastal marine ecosystems.
The Pacific water inflowing through the Bering Strait is a predominant source of heat, fresh water, and nutrients in the Arctic Ocean. Its transport has a potential to affect both the sea ice variation and marine ecosystem.
Since this water is loaded after unloading cargo and then discharged at the port when cargo is loaded, its impact on the marine ecosystem is raising concerns because invasive/alien species are brought in with the ballast water.
Advancements to fishing gear design, sourcing decisions, fishing policies and disposal of end-of-life fishing gear can significantly reduce the impact of ghost gear on marine ecosystems, livelihoods, and wildlife.
His research specialties include marine ecology and biodiversity, bio-physical and social impacts in coastal zones, management of coastal resources and small-scale fisheries, and marine conservation.
Improved understanding of the complex interactions between species will be important for predicting the likely composition of marine ecosystems under future climate change and ocean acidification, the authors conclude.
