Thermohaline circulation
Thermohaline circulation (THC) is a part of the large-scale ocean circulation driven by global density gradients formed by surface heat and freshwater fluxes.

What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
Foundations · builds on
Thermohaline circulationdepends onSalinityEstablished
thermohaline circulation depends on salinity.
Mechanism: Thermohaline circulation is driven by salinity and temperature: salty, cold water is dense and sinks, powering a slow global conveyor of ocean water.

System context
Thermohaline circulationis part ofOcean currentEstablished
thermohaline circulation is part of ocean current.
Mechanism: The thermohaline circulation is the global 'conveyor belt' of deep ocean currents driven by temperature and salinity.

Open Atlantic overturning (AMOC) →
The Atlantic conveyor.
Mechanism: The AMOC is the Atlantic arm of the global thermohaline circulation, and it is weakening.
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Removing this node severs the only sampled structural route between Atlantic overturning (AMOC) and Climate — a non-redundant bridge here.
structural · Structural removal simulation — not a historical or causal counterfactual.
50% of its relationships cross field boundaries, reaching 6 other disciplines — unusual in a discipline where most concepts stay within their field.
structural · Structural graph analysis — not a claim of importance, causation or history.
Currently dark in the atlas: no key date stored · 4 of 4 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 1 foundation (requires / depends-on / derived-from / emerges-from).

Strengths & constraints
Strengths
- Cross-disciplinary connector — 50% of its relationships cross field boundaries. structural
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- Non-redundant bridge — removing it severs a sampled route between neighbouring clusters. structural
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
