House Station Photographs Reveal Earth’s ‘Bloody’ Lakes

Astronauts have captured a “bloody” phenomenon operating by way of a number of the Earth’s lakes whereas on board the Worldwide House Station.

They took images exhibiting our bodies of water flowing in crimson colours attributable to an abundance of algae and micro organism lurking within the water.

One {photograph}, posted to the NASA Earth Observatory, exhibits the Laguna Colorada, also referred to as the Purple Lagoon within the Bolivian Andes, from above. This lagoon is legendary for being brilliant crimson in look, and based on native folklore, the lake is not filled with water in any respect, bur slightly the blood of gods.

The reddish hues are attribute of hypersaline environments—the place our bodies of water are usually saltier than regular seawater. In these lakes, crimson algae and different microorganisms are so considerable that they shade the water vibrantly.

Some lakes see extra of this algae progress than others. Its progress is dependent upon a number of components, together with water temperature, gentle and the saltiness of the water. The algae within the Laguna Colorado is an important meals supply for flamingos, which come to the water to feed.

One other picture captured by the astronauts exhibits the Betsiboka River Delta in Madagascar, revealing water flowing in crimson and brown colours.

The redness of this river, and different waters in Madagascar, is attributable to the iron-rich sediment, the NASA Earth Observatory reported.

Many photos have been captured of those bloody waterways earlier than by satellites and astronauts. In keeping with a earlier report from the NASA Earth Observatory, one astronaut, upon assembly the president of Madagascar mentioned: “Oh, sure, I do know your nation. It’s the one bleeding into the ocean.”

The sediment flows by way of the river and generally clogs waterways. Nonetheless, it additionally sometimes types new islands, the place mangroves develop.

The Nice Salt Lake in Utah has additionally seen a excessive quantity of crimson algae blooming in its waters up to now.

A satilite picture beneath exhibits the lake from above, the place half the water is coloured with a reddish tint.

Whereas the bloody shade could look unusual, some algae gives important water sources for hen species and marine life.

Within the Betsiboka River Delta, the seagrasses within the estuary present meals to endangered inexperienced turtles and sea cows.

An extreme quantity of algae in water might be dangerous. Purple tide, for instance, is a sort of algal bloom that grows shortly and may shade waters brilliant crimson. Excessive concentrations of this algae might be poisonous to marine life. Hotter waters, affected by local weather change, may cause excessive quantities of crimson tide in lakes and rivers.
