The research station
Our research station is located on the Eastern rim of the Crater. It was built by the Ngorongoro Conservation Area Authority (NCAA) close to a rangers camp and is situated close to Ngorongoro Sopa Lodge; the nearest Maasai village is about 5 km away. Equipment and food can be bought a one-hour drive away in Karatu.
The station is run with solar power and equipped with computers, printers, scanners etc.; access to the internet comes via a satellite dish. One room is dedicated to sample processing and storage, and is equipped with a centrifuge, a liquid nitrogen container and equipment to perform dissections.
