BGSCET Hackathon 2025 — Karnataka Coastline

India's Marine
Trophic Collapse
Early Warning System

BlueWhale monitors 5 IUCN-aligned ecosystem indicators across Karnataka's 320km coastline — computing real-time regime shift probability before irreversible collapse occurs.

The Crisis

Every existing tool
detects what's already dead.

BlueWhale predicts what's about to die — and fires alerts before the trophic cascade becomes irreversible. Because once a marine ecosystem crosses the regime shift threshold, internal feedback loops prevent recovery.

Trophic Cascade Risk

Overfishing removes apex predators → mesopredator explosion → prey collapse. Karnataka lost 67% of Whale Shark sightings in 5 years. Cascade already in progress.

⚠ 73% regime shift probability
💀
Hypoxic Dead Zones

Arabian Sea OMZ intrudes Karnataka coast seasonally. Sasihithlu zone: DO at 1.4 mg/L — below 2 mg/L dead zone threshold. Marine life suffocating.

⚠ DO: 1.4 mg/L at Sasihithlu
⚠️
Regime Shift Alert

84% probability of irreversible regime shift at Sasihithlu within 7 months. Once crossed, internal feedback loops prevent ecosystem recovery. The Black Sea never recovered from its 1989 collapse.

⚠ 7 months to threshold
How It Works

Detect → Analyze → Alert

01
📡

Detect

AI Vision analyzes coastal imagery every cycle. Citizen reports fill real-time gaps. Every data point geotagged and validated automatically.

Gemini Vision + Crowdsource
02
🧠

Analyze

Computes 5 IUCN-aligned sub-indices per zone: Dissolved Oxygen, MSA biodiversity index, Fishing Mortality vs MSY, SST anomaly, and pollution density.

Ecosystem Score Engine
03
🚨

Alert

Direct automated alerts to Coast Guard, KSPCB, NGOs. Fishermen get SMS zone advisories. Fire alarms, not fire investigations.

SMS + Authority Integration
Platform Features

Built to predict,
not just report.

Designed for hackathon judges and real-world coastal authorities.

Ecosystem Intelligence Map

Full-screen Leaflet map with 6 Karnataka coastal zones. Each zone shows live regime shift probability, 5 sub-indicators, and IUCN species risk. Click any zone to dive deep.

🤖

Gemini AI Pollution Scanner

Upload any coastal photo. Real Gemini 1.5 Pro Vision classifies by MARPOL category, estimates DO impact radius, maps trophic cascade threat, and recommends specific authority to alert.

🐢

Species Trophic Monitor

5 IUCN-listed species tracked with MSA index. Hawksbill Turtle (CR), Whale Shark (EN), Dugong (functionally extinct in Karnataka). Interactive food web shows cascade consequences.

🎣

Fisherman Advisory System

Fishing Mortality (F) vs Maximum Sustainable Yield (MSY) per zone. Real-time "Do Not Fish" advisories with safe zone alternatives — no smartphone required.

8 more weeks.

3 lakh fishing families on Karnataka's coast depend on ecosystem health we're currently flying blind on. BlueWhale changes that.
