Crimea’s ‘Putrid Sea’ from Space: A Colorful Spectacle with a Stinky Secret
In a striking satellite image captured by Landsat 8 nearly a decade ago, the Sivash region in the northern Crimean Peninsula reveals a breathtaking array of colors in a series of shallow lagoons known as the “putrid sea.” The vibrant hues, ranging from raspberry and peach to lime green and brilliant blue, create a deconstructed rainbow that captivates the eye. But behind this stunning visual display lies a fascinating yet foul-smelling secret.
The Enigmatic Colors of the Sivash Lagoons
Stretching across approximately 3,900 square miles, the Sivash region is home to more than a dozen multicolor lagoons, each with its own unique palette of colors. The vibrant hues are a result of various factors, including the presence of microorganisms within the lagoons. The waters of these shallow pools, ranging from 2 to 10 feet in depth, are hypersaline, containing high levels of minerals that contribute to their salty nature.
The diverse colors of the lagoons are influenced by the minerals, acidity, and vegetation present in each body of water. However, the primary driver of the vivid hues is the species of algae that bloom in the lagoons’ waters. During the summer months, these algae blooms emit a distinct rotten egg-like odor, earning the region its unflattering nickname.
A Natural Haven Teeming with Life
Despite its pungent aroma, the Sivash region is a thriving ecosystem teeming with wildlife. Protected by the International Convention of Wetlands, the lagoons are home to a variety of salt-resistant plant species and serve as a vital habitat for up to 1 million water birds that migrate to the area every winter. The region’s rich mineral deposits also support a large chemical plant that extracts minerals for industrial use.
A History of Conflict and Resilience
The Sivash region has not only been a haven for wildlife but also a battleground for human conflict. During the Russian Civil War in November 1920, the Red Army orchestrated a daring ambush in the Sivash lagoons, ultimately securing control of the Crimean Peninsula from the White Army. This historic event, known as the Siege of Perekop, highlights the region’s strategic significance and its role in shaping the course of history.
As we marvel at the beauty of the “putrid sea” from space, let us remember the complex interplay of natural processes, human history, and environmental conservation that define the Sivash region. From its vibrant colors to its storied past, this unique ecosystem continues to captivate and intrigue observers around the world.
