NASA Space Apps Challenge 2025

Tracking Sharks from Space

Using satellite data, AI, and real-time ocean sensors to understand and protect marine ecosystems.

Core System Components

Satellite Data

Ocean Chlorophyll concentration, Fluorescence line height, Total Absorption at 412nm, Total Backscattering at 412nm, Diffuse Attenuation coefficient at 490nm, Particulate Inorganic Carbon, Remote Sensing reflectance at 412nm and Sea Surface Temperature

AI Model

Predicts foraging zones based on location and enviromental factors.

Smart Tags

Non-invasive sensors attached to sharks record depth, temperature, images, and movement, transmitting data when near a buoy.

Smart Buoy
Network

Specialized buoys are deployed in predicted zones to gather in-situ ocean data and receive transmissions from tagged sharks.

Hybrid Data Transmission

The system operates in two modes: synchronous (direct GPS or satellite link) and asynchronous (data stored until contact with a buoy).

Data Integration & Analytics

All transmitted data — both synchronous and asynchronous — is unified, processed, and analyzed to refine movement predictions and environmental correlations.

Three Core Pillars

Our project combines satellite data, artificial intelligence, and ocean-based technology to monitor, predict, and protect shark habitats — ensuring the survival of these vital apex predators.

Data Flow Overview

Track how information moves from sharks to satellites through smart tags and buoys, ensuring timely insights for conservation and research.

  • Synchronous Transmission: Real-time data sent directly to GPS and monitoring systems.

  • Asynchronous Storage: Data buffered in smart tags until a buoy can relay it to satellites.

  • Integrated Feedback: All collected information feeds prediction models to optimize buoy placement and shark tracking.
