Virág párbaj, Barents Tenger
As the seasons pass on Earth, different species tend to dominate the landscape at different times. Such was the case in July 2014 in
the surface waters of the Barents Sea, north of Norway and Russia. The Aqua satellite captured a transitional moment between one
form of microscopic, plant-like organisms (phytoplankton) and another.
Several currents merge in this area, and intersecting waters combine with stiff winds to promote mixing of waters and nutrients from
the deep. Note the green swirls on the center and left, as well as the milky, blue-white swirls on the upper right. (The fluffy white area
is cloud cover.) It is likely that the green plankton were diatoms and the white ones were coccolithophores. Research has suggested
that diatoms start to bloom in the well-mixed, cooler waters of spring and dominate the early summer. As the water warms and
becomes more stratified or layered, coccolithophores bloom more abundantly.
