WhaleDataset-VisualAnalysis 🐋🐬

This project presents a visual analysis of whale and dolphin sightings using a dataset provided by OBIS-SEAMAP.
The analysis explores spatial and temporal patterns of marine mammals across different geographic regions and time periods, using a variety of visual techniques.

📊 Key Features

• 📍 Geospatial Mapping
  Using scatter_geo, whale and dolphin sightings are plotted globally based on latitude and longitude.

• 🌡️ Environmental Analysis
  The dataset includes sea surface temperature, bathymetry (depth), and latitude, allowing comparisons across species and oceanic regions.

• 📦 Species Grouping and Aggregation
  Observations are grouped by species, enabling average-depth, temperature, and spatial distribution analysis.

• 📈 Temporal Trend Analysis
  Sightings over multiple decades are visualized to explore possible seasonal or long-term trends.

• 🎨 Visual Methods Used

  • Heatmaps
  • Boxplots
  • Countplots
  • Scatter plots
  • Strip plots
  • Interactive geographical maps (plotly)
