- Dust storms from the Sahara Desert blow out over the Atlantic Ocean, obscuring the Cape Verde Islands, in these images from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite captured during the summer and fall of 2002, as well as early 2003. Dust transport can have positive and negative consequences. On the one hand, it can bring minerals and nutrients from the soil to marine ecosystems. On the other hand, it can carry viruses and fungi that decimate corals as far away as the Caribbean.
- Tonian (Wikipedia)
The Tonian (from Ancient Greek: τόνος, romanized: tónos, meaning “stretch”) is the first geologic period of the Neoproterozoic Era. It lasted from 1000 to 720 Mya (million years ago). Instead of being based on stratigraphy, these dates are defined by the ICS based on radiometric chronometry. The Tonian is preceded by the Stenian Period of the Mesoproterozoic Era and followed by the Cryogenian.
