APPENDIX 3 - LIST OF PRE-EVENT CHALLENGE QUESTIONS POSED BY THE EVENT AMBASSADORS
Challenge Questions
How do trash generation rates correlate with traffic count?
When applying machine learning to trash imagery, is it most effective to analyze by quantity, quality, or categories of trash?
What is the uncertainty associated with trash visual assessments for quantifying trash loading ?
How can machine learning be used to reliably quantify trash volumes and/or types in images?
Can we design an app to maximize public engagement that also captures useful data for track trash mitigation effectiveness?
Characterizing differences between upstream and coastal debris data - how does the assemblage of trash / litter / debris change within the watershed, and do we see a clear signal of ocean-sourced debris in the coastal data?
How do estimates of type and quantity of trash in local and regional trawl surveys contribute to knowledge of sources and loadings to Santa Monica Bay?
How can trawl trash data be combined with other datasets to estimate microplastics generated via trash in the ocean?
Do socioeconomic factors affect trash generate rates?
In Sacramento, If the vegetation is green in the summer, more than likely there is a hired landscaper that is also picking up trash. Would there be a way to look at satellite imagery and get correlations between green vs brown roadside edges and trash scores to use to exclude these areas from our priority land uses?
Do trash cans at bus stops alleviate litter issues or increase trash issues? Is there a difference between open trash cans and the compactors?
What are the costs per unit trash removal or acre treated using street sweeping, drain inlet devices, hydrodynamic separators, litter pick-up crews vs in-stream clean ups?
Are there any factors in rivers/streams that can predict the level of trash?
How much trash is in California?
What is the spatial distribution of trash?
What are the most prevalent trash types? Has this changed over time?
Create a comprehensive litter dataset to identify the most common item types according to volume, weight, flux, material, product, source, brand, and other units of importance.
Analyze the effectiveness of Trash Total Maximum Daily Loads (TMDLs) on reducing the flow of trash from stormwater systems to the ocean.
Analyze the effectiveness of full capture systems versus other best management practices as removing trash from waterways.
What trash removal credit could be claimed through a straw ban?
Are bans/tmdls effective (e.g. bag, styrofoam)?
Is there a difference in trash amounts in rivers/streams in Track 1 vs Track 2 areas?
Analyze the impact of the single-use plastic carryout bag ban on reducing disposable bag use, preventing ocean litter, and reducing government costs.
How do we identify trash mitigation actions that provide the greatest trash reduction benefits?
How do local, regional, and statewide policies, like bag bans, straw bans, and extended producer responsibility affect the amount and composition of debris found on California's beaches?
What sources of data are available to track the quantity and type of Tobacco Product Waste (TPW) ?
Where are TPW hot spots?
What are different group perceptions and actions on TPW? • Parks and Recreation • Environmental • Public • Tobacco Users
