AI-powered seabed intelligence
The ocean surface hides what lies beneath.
Thousands of kilometres of seabed can be surveyed with sonar. Finding the debris hidden within those images still takes time, expertise and manual inspection.
TARANG turns Side-Scan Sonar imagery into actionable seabed intelligence.

02 / OCEAN WATCH
What the ocean hides
The deeper we look, the more we discover.
Underwater debris can blend into sand, rock, reef and seagrass. Ghost nets, fishing gear, barrels, tires, pipes and wreckage rarely announce themselves from the surface.
The first challenge is not removing debris. It is knowing where it is.

03 / THE CLEANUP GAP
Beyond the shoreline
We clean what we can see.
Coastal action matters. Yet the objects already resting on the seabed are out of sight, dispersed across a vast and changing underwater landscape.
TARANG helps survey and cleanup teams turn a difficult search into a focused response.
DEPTH REACHEDBelow the visible ocean.
05 / SONAR AI REVEAL
From acoustic image to target
Sonar gives us the eyes. AI gives us the intelligence.
Side-Scan Sonar captures acoustic texture and shadows, not a conventional photograph. TARANG makes potential human-made objects easier to review, understand and locate.
01Acoustic shadows expose height and shape beyond the immediate target.
02Noise, changing seabed texture and dropouts are considered before a finding is surfaced.
03Every potential finding remains a reviewable signal—not an automatic conclusion.

06.5 / CONTEXT MATTERS
Natural vs artificial
Not everything unusual is debris.
Seabed intelligence needs context. TARANG is designed to help distinguish natural formations from objects that may need attention—so teams can focus their expertise where it matters.
FORM + EDGESRegular outlines, mesh or manufactured geometry can stand apart from organic formations.
ACOUSTIC SHADOWShadow length and direction help describe a target’s height above the seabed.
TEXTURELocal texture can vary between sand, reef, rock, seagrass and debris.
HUMAN REVIEWConfidence guides attention; specialist verification informs the final decision.
07 / HOW TARANG WORKS
Connected, not isolated
From seabed survey to field-ready intelligence.
TARANG is not only a computer vision model. It connects acoustic evidence, location information, review and reporting in one practical flow.
Capture sonar and navigation data
Survey teams acquire Side-Scan Sonar imagery alongside the information needed to place a survey in geographic context.
Process a difficult underwater signal
Imagery can contain speckle, shadows, changing resolutions, seabed textures and dropouts. The system prepares it for analysis.
Surface potential anthropogenic objects
AI identifies candidates for review while natural seabed structure is considered to reduce unhelpful leads.
Associate findings with place
Sonar metadata helps connect a reviewed target with a map-safe location and survey context.
Prioritize a response
Findings become concise reports that support expert verification, survey planning and responsible cleanup action.
08 / IMPACT
Deployment record
Public impact, grounded in the platform.
These project metrics come from TARANG’s public-safe statistics endpoint. When it is unavailable, this page keeps its structure without substituting invented results.
Source: TARANG public statistics API. Counts reflect the current deployment database and are not estimates of national marine debris. Public pages intentionally avoid sensitive operational information.

A map built for signal, not spectacle.
Public-facing locations are deliberately rounded. Operational routes, raw sonar and precise target data remain inside the secured platform.
