Current project

The marine environmental effect of Saharan-dust deposition in the Atlantic Ocean

Million tons of Saharan dust are depositied into the Atlantic every year. This brings both refractory lithogenic material and new nutrients into the system, affecting primary production and particle export that transfers CO2 from the surface into the deep ocean.

  

① The wind blows dust through the atmosphere

② Dust minerals contain nutrients and metals

③ Dust is deposited into the ocean - wet or dry deposition

④ Nutrients may be released into the water

⑤ Bioavailable fraction is used by the phytoplankton

⑥ Phytoplankton conducts photosynthesis and consume CO2

⑦ Phytoplankton is eaten by zooplankton

⑧ Dead cells and fecal pellets aggregate & sink to the bottom

⑨ Remaining organic matter settles out the water column and reaches the ocean floor

⑩ CO2 is sequestered

In order to determine the fluxes involved, an array of sediment traps were moored at 1200 m and 3500 m depth at five stations along a transect at approximately 12⁰N to monitor setteling particle fluxes for three years. Every year these sediment traps were serviced.

Haboobs
Dust outbreaks are most often impressive events. One of the most spectacular dust storms is the so-called "haboob". Although initially described in Sudan, Africa, they have also been observed in other dry areas. Last week, a spectacular haboob in…

Australian dust cycle
The Australian dust cycle is a "natural laboratory" for the production of mineral dust. Nowhere else on the planet is the process so clearly visible and chances are that in a few months, huge dust outbreaks will happen again!
