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
