To Janet: On the reported pollution from plastic bags

# data[].attributes.body
You indicated that, in the mentioned areas/cities, plastic bags are the largest fraction of total plastic pollution. Is this in terms of number of items, total mass or both? Many thanks!

# data[].attributes.body
Great Presentation Janet! Thanks! Do you use deep learning for the detection of the plastic shapes by the cameras (GoPro, normal cameras)?

# data[].attributes.body
You mentioned the UN hotspot monitoring methodology. Could you please explain in broad terms in what consist?

Dear Janet and all, I am the Director of the EUREKA Cluster CELTIC-NEXT, one of the clusters part of the EUREKA Clusters Program (ECP).
EUREKA is an intergovernmental network of countries, including Europe, Canada, South Korea, Singapore, promoting international cooperation for R&D&I actions.
EUREKA ECP is foreseeing a series of Joint Thematic Calls on Accelerating Sustainability, starting mid 2022, looking first at Space-Earth-Ocean Integrated System to accelerate Sustainability.
As said, Singapore and South-Korea are members of the EUREKA network of Nations and can/will participate to this call. It will provide a great opportunity to collaborate on those topics between your region and Europe + Canada, South Africa and others.
You can monitor the Eureka site for the announcement of the call: https://www.eurekanetwork.org/
or contact emir.sirage@aircentre.org
or contact me at priem@celticnext.eu
Looking forward to supporting sustainability together,
Xavier

At the moment quantifying plastic leakages into eg waterways is one of key challenges and usually relies on very big assumptions. How are you accounting for this in the Closing the Loop project in a way that is realistic? And a more general point for discussion - how can remote sensing help in assessing this better?

# data[].attributes.body
In my opinion, there should be greater openness in this community in sharing data. In my investigation project, I had to get and process data that was already studied, which took me time that could be used to find the new data, which would have benefited the community.

We are based in Hong Kong and have been focusing on ocean debris. We do use drones in a.lot of our work and not sure if appropriate channel here but looking for hi-res images of beaches with trash around the world for a comparative study. My email is gary@oceansasia.org and any help from anyone here would be greatly appreciated.

Are there any data collection tools that private boats or sailboats could use to support science or any projects?

Testing the algorithms, if available for sharing?!

Skyflox: Using commercial aircraft as a new Earth Observation platform

# data[].attributes.body
Dear all, we from SkyfloX (a European Space Agency (ESA) ‘Spin-Off’ company) are developing ORCA (Optical and Radio frequency Constellation on commercial Aircraft). The ORCA concept proposes to use commercial aircraft as a platform to carry small equipment. Several such equipped aircraft form a constellation which may support several Earth Observation services (https://skyflox.eu/ ). Such data could then be used for a multitude of applications (from forest fire detection to urban monitoring or in this case marine litter detection along coastal areas, provided that the right sensors are installed). I believe there is potential here to fill the data gap and set up a monitoring service: using a constellation of aircraft as a new source of data, to complement satellite and drone data.

What are some of the popular softwares being used at the moment to identify land-based litter from drone imagery or GoPros from cars?

Would not Sargassum also aglutinate macroplastics, due to ocean dynamics? So Sargassum accumulating in places where plastic will go too.

Since the port represents a relatively small area, I believe the best method to detect floating debris would be to use a drone (good spatial resolution, small area and easy to use).
