Snow bloom refers to the rapid growth and increase in numbers of so-called snow algae on the surface and interior of snow fields. Typically occurring as the surface of the snow warms in the springtime sun, the algal growth confers various colors to the...

Snow algae describes cold-tolerant algae and cyanobacteria that grow on snow and ice during alpine and polar summers. Visible algal blooms may be called red snow or watermelon snow. These extremophilic organisms are studied to understand the glacial...

It's truly spring when those last white drifts go technicolor Microbiologist Brian Duval hates this part, so let's just deal with the snickering up front. Yes, he studies yellow snow. He also studies red, green, and orange snow and would love...

ABSTRACT Aplanospores of Chlamydomonas nivalis are frequently found in high-altitude, persistent snowfields where they are photosynthetically active despite cold temperatures and high levels of visible and ultraviolet (UV) radiation. The goals of this work were to characterize the UV environment of the cells...
