By James B. DuttonThe National Geographic Society’s expedition to Zanzibia is bringing us a new look at one of the worlds largest underwater caves.
The expedition, dubbed Zanzil, has discovered a site that’s larger than London and more than the size of the US state of Connecticut.
It is the largest underground cave in Africa, and the deepest in Africa.
Zanziland has been a haven for people from around the world since the 1970s, and it was one of only a handful of countries in the world to have the caverns.
The Zanzilians also have the largest and oldest known archaeological site in Africa and the largest gold-rich deposits of gold in Africa — more than 20 percent of which lie beneath the water.
The project was launched in 2007, with the first expedition being the first to enter the cavern.
Since then, more than 150 expeditions have been launched to the Zanzile, and more are planned.
The first expedition, in 2002, was a success.
But, as the expedition has grown, so have its challenges.
The team’s goal has been to explore the cavern using technology like underwater cameras and sonar.
The cavern’s natural environment and geological conditions make it an ideal location to study a wide range of creatures, including sharks, whales, and sea turtles.
The depth at which the cavern was first explored, and its age, also make it a unique environment for studying species of the deep sea, including the endangered Bluefin Tuna.
The researchers also want to explore its mineralogical features to better understand the history of the cave.
And the team has a few things to keep in mind: The cavern is underwater, and only about 1 in 2,000 cubic meters of it is underwater.
The majority of the cavern’s rocks, which make up about 95 percent of the total volume, are in the bottom of the chamber.
That means it has been in the water long enough that the water can corrode the rocks and give the cave a rocky appearance.
The cave has an abundance of silica deposits and large amounts of iron, copper, and zinc.
It has also had a relatively high degree of carbonates, which can cause problems with carbon-14 production, and high concentrations of carbonate minerals.
So far, the scientists have not encountered any fish or animals that would be particularly dangerous to human beings.
But some things to watch out for are the pH, which is a measure of acidity in the air.
The acidity of water varies in different environments.
It ranges from 6.6 to 7.2 in the lower reaches of the sea, where water is most acidic.
The highest pH in the deep waters is around 7.3, which means the water is nearly crystal clear.
It’s not a problem in the upper reaches of Zulu River, but the pH of the Zulu is higher than the lower Zulu, and that can affect the way water reacts.
In the lower depths of the ocean, where the water pH is lower, it’s usually around 8.5.
That’s where it can be a problem.
The oxygen in the atmosphere, also known as the oxygen isotope ratio, can affect how well the water reacts to CO 2 and other gases.
Because the cave is so deep, it also has a lot of sediment, and sediment in the deeper waters of the river can contain oxygen.
The sediment can make the water less acidic.
And it can make it more acidic.
So, when the water in the cave gets very alkaline, the oxygen in it gets reduced, and this results in a lot more oxygen being in the groundwater, which causes the water to be less acidic as well.
This has happened in Zanzia, too.
The water levels of the groundwater have been dropping because of pollution.
But as more of the underground water is flushed out of the water table, it will slowly return to the normal levels of acidification.
So this has been happening in the Zancle rivers in recent years, and a few years ago, the water level of the rivers were rising and water quality was improving, said Mark Mair, an archaeologist with the National Geographic team.
But it was only after this first expedition that the team realized that this wasn’t the case.
This cavern, like the rest of Zancia, has not been visited for a long time, and because it was never explored, it was difficult to find any evidence of life, said Dr. David W. Smith, a geologist with British Antarctic Survey.
“We have a good understanding of what is going on, but we are still waiting for people to come and go, and we have to know where they are going, and who they are, and what they are doing,” Smith said.
The second challenge the team faced in the first trip was finding a way to access the water for the first time.
That was particularly difficult because the cave has been underwater for so long. “You
