Log a wider litter sweep along the Maré waterfront

Beyond a single transect line, Complexo da Maré's waterfront needs a broader documented sweep covering multiple access points so a future cleanup crew knows where debris concentrates most. This wider stand-off survey builds on the initial transect with a fuller picture across several vantage points. Given the canal's documented contamination, this stays a photograph-and-log task from public ground. Standard: UNEP marine litter reduction guidance; SDG 14 (Life Below Water) Proof: Photo log of the multi-point litter sweep Method (UNEP marine litter reduction guidance; SDG 14 (Life Below Water)): 1. Identify three to five public vantage points along the waterfront. 2. Photograph debris concentration at each point from a safe stand-off distance. 3. Log an approximate count and type of debris at each point. 4. Rank the points by apparent debris concentration. 5. Submit the sweep log with photos attached. Done when: Photo log of the multi-point litter sweep

$160 proposed

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 45–90 minutes. Method of record: EPA National Wetland Condition Assessment (rapid method)

Bring

• GPS phone
• quadrat frame
• invasive-species ID reference
• boots
• insect protection
• camera

Steps

1. 1. Navigate to the wetland edge; record GPS; stay on stable ground.
2. 2. Photograph 3 quadrat stations.
3. 3. At each station, estimate percent cover native vs invasive; identify the dominant invasive.
4. 4. Note hydrology / water level and any disturbance.
5. 5. Enter cover percentages, invasive ID, hydrology, GPS, photos into the proof record; sign.

If it does not match the plan

• Standing water + wildlife (snakes/alligators) -> maintain distance; never sample alone.
• High invasive cover -> flag for a management/removal plan.

What counts as done

• Percent cover native vs invasive recorded at 3 stations
• Dominant invasive species identified
• Hydrology / water-level note recorded
• GPS waypoints + quadrat photos

Proof is measured against these, not judged by taste.
