Caractérisation multi-proxy de « poussières Sahariennes » déposées à l'actuel sur la marge Ouest africaine : relations avec les régions sources et les systèmes de transport et implications pour l’interprétation des archives sédimentaires en Atlantique Tropical Nord-Est

A dissertation presents a multi-proxy analysis of Saharan dust deposited on the present West African margin. It examines links with source regions and transport systems and discusses implications for interpreting sedimentary archives in the northeastern Tropical Atlantic.

Illustrative image: On 30 March 2026, a major dust storm formed in the south of Algeria, disrupting trans-Saharan transport routes and affecting air quality across West and North Africa. The storm moved southwards, passing through Mali and Mauritania towards the west coast of Africa throughout the day. It formed a front approximately 2,000 km long, which travelled all the way to the Canary Islands, where a severe “Calima” episode alert was issued.

Generated scores

Scores are based on the cited reporting and use a 1–10 scale. Read the methodology.

Confidence: 5/10How certain the assessment is based on the clarity and evidence in the cited reporting.
Geographic reach: 6/10How widely the event reaches, from a local area (1) to worldwide impact (10).
Global importance: 3/10The event's broader significance, from limited importance (1) to major global importance (10).
Impact magnitude: 3/10The scale or severity of the real-world impact, from minor (1) to extreme (10).
Positivity: 6/10How harmful or beneficial the event is, from strongly harmful (1) to strongly positive (10).
Urgency: 1/10How time-sensitive the event is, from low urgency (1) to immediate attention needed (10).

Why it matters

The study informs interpretation of sedimentary archives relevant to regional dust-transport and climate research.
