FloatChat 🌊 – AI-Powered ARGO Data Explorer

FloatChat is an AI-powered conversational interface for exploring ARGO float oceanographic data. It allows users to query, explore, and visualize oceanographic information using natural language.

---

📝 Features

• Chatbot-style interface with ChatGPT-style bubbles
• Floating input at the bottom for easy conversation
• Interactive visualizations:
  • Float locations on a map
  • Pressure and other parameter time-series
• Backend:
  • PostgreSQL for structured ARGO data
  • ChromaDB for vector search and metadata retrieval
  • Retrieval-Augmented Generation (RAG) for natural language query handling

---

💻 Tech Stack

• Python 3.x
• Streamlit – Frontend dashboard and chat interface
• Plotly & Leaflet – Interactive plots and maps
• PostgreSQL – Structured ARGO dataset
• ChromaDB – Vector database for semantic search
• Flan-T5 / Local LLM – Query interpretation

🚀 Demo Queries

Try the following queries in the chat interface:

1. Show me the temperature and pressure profiles of ARGO floats near the equator.
2. Compare salinity levels in the Arabian Sea and Bay of Bengal over the last 6 months.
3. What are the nearest ARGO floats to latitude 10°N and longitude 75°E?
4. Show me pressure vs depth for floats in the Indian Ocean.
5. Plot the pressure trends of ARGO floats in March 2023.

⚡ How to Run

1. Activate your virtual environment: & D:/my_project/venv/Scripts/Activate.ps1 Run the Streamlit app:

bash Copy code cd D:\floatchat streamlit run front_end/app.py Open in your browser: http://localhost:8501/

📌 Notes Demo uses a subset of 500 ARGO floats for speed.

Designed for internal hackathon PoC.

Fully functional chat + inline visualizations for Indian Ocean ARGO dataset.

🔗 Future Work Full ARGO dataset integration

Additional BGC and satellite data

Enhanced RAG pipeline for advanced queries

Improved UI/UX and multi-modal visualizations
