Dolphin and Sewage Spill Correlation Analysis

I am trying to see if there is any relationship between dates and locations of dolphin sightings with the locations and dates of sewage spills.

I need a comprehensive spatial and temporal analysis to assess the spatiotemporal correlation between dolphin sightings and sewage spill events.

Key requirements:
- Analyze dolphin location data and sewage spill data.
- Focus on spatiotemporal correlation.
- Use appropriate statistical and spatial analysis tools.

Ideal skills:
- Expertise in spatial analysis (hotspot, pathway, cluster).
- Strong background in statistical correlation methods.
- Proficiency with GIS software and data visualization.

Please provide samples of similar work.
