Ocean Networks Canada

 Ocean Networks Canada - "Ocean Networks Canada is a University of Victoria initiative that operates the NEPTUNE and VENUS cabled ocean observatories in the northeast Pacific Ocean and the Salish Sea. Additionally, Ocean Networks Canada operates smaller community-based observatories offshore from Cambridge Bay, Nunavut.,[1] Campbell River, Kitamaat Village and Digby Island. These observatories collect data on physical, chemical, biological, and geological aspects of the ocean over long time periods. As with other ocean observatories such as ESONET, Ocean Observatories Initiative, MACHO and DONET, scientific instruments connected to Ocean Networks Canada are operated remotely and provide continuous streams of freely available data to researchers and the public.[citation needed] Over 200 gigabytes of data are collected every day.[2]" -Wikipedia

Abstract:

In recent years, airborne microplastics have been identified in a range of remote environments. However, data throughout the Southern Hemisphere, in particular Antarctica, are largely absent to date. We collected snow samples from 19 sites across the Ross Island region of Antarctica. Suspected microplastic particles were isolated and their composition confirmed using micro-Fourier transform infrared spectroscopy (µFTIR). We identified microplastics in all Antarctic snow samples at an average concentration of 29 particles L−1, with fibres the most common morphotype and polyethylene terephthalate (PET) the most common polymer. To investigate sources, backward air mass trajectories were run from the time of sampling. These indicate potential long-range transportation of up to 6000 km, assuming a residence time of 6.5 d. Local sources were also identified as potential inputs into the environment as the polymers identified were consistent with those used in clothing and equipment from nearby research stations. This study adds to the growing body of literature regarding microplastics as a ubiquitous airborne pollutant and establishes their presence in Antarctica.

"Drawing directly upon work by the European ATLAS project (2016-20) this Research Topic will explore recent findings and themes emerging as both the marine scientific and management communities embrace assessments of marine ecosystem connectivity, biogeography and function at ocean basin scale. Research and policy development at basin scale has been driven by the realisation that climatic change and anthropogenic impacts are rapidly altering marine ecosystems at the same time as governments seek to promote increased economic output from the marine environment. This broad context sets the considerable challenge and opportunity for marine science, industry, management and policy to shape the frameworks through which this sustainable economic ‘Blue Growth’ can be achieved.

This Research Topic will bring together key advances and approaches relevant to ocean basin-scale research and management. Studies built upon new discoveries from poorly-understood deep ocean ecosystems (e.g. coral, sponge, vent & chemosynthetic fauna) are now highlighting the opportunities for the scientific community to create a new evidence base for long-term management. For example, advances in oceanographic data availability, modelling resolution and a better understanding of larval biology and dispersal are fostering more interdisciplinary partnerships between physicists and biologists to model......cont."
