Split Signals End for Remnant of Antarctic Iceberg A68a

The once-mighty iceberg A68a looks to be in its death throes.
The largest fragment from a block of Antarctic ice that originally measured some 5,800 sq km (2,240 sq miles) in area has suffered another major split.
Satellite imagery shows at least two segments drifting close together about 135 km south-east of the British territory of South Georgia. They will no doubt soon move further apart.
For more than three years, A68a was the biggest iceberg in the world.
At its greatest extent, it was about a quarter of the size of Wales - or New Jersey or Israel.

Martian Mineral, Rare on Earth, Found Locked in Antarctic Ice

Scientists boring more than a mile deep into Antarctic ice have unearthed a mineral that's rarely seen on Earth but found in abundance on Mars.
The yellow-brown mineral, called jarosite, requires both water and acidic conditions to form, according to NASA — conditions that are hard to find now on the Red Planet.
Nonetheless, after the Opportunity rover first discovered jarosite on Mars in 2004, the mineral turned up in several Martian locations, leaving scientists to wonder how the mineral became so common, Science reported.
Some theorized that, when ice covered the planet billions of years ago, dust containing the required minerals — iron, sulfate and potassium — may have been trapped inside.

The Zoological Survey of India has started tagging endangered olive Ridley to track their migration path in the off-shore waters of Odisha.
The ZSI scientists took six turtles floating in the deep water of the Bay of Bengal and attached the tags made of aluminium before releasing them back in the sea.
Tags were attached to six including four female and two male turtles. Basic information such as their weight and length was recorded by the researchers.
According to Amlan Nayak, Divisional Forest Officer of Berhampur, ZSI would tag 30,000 turtles to know where they come from and go to.
