We've had a lot of new arrivals while I've been ensconced with data, so I suppose I'll start with a reintroduction. I'm Martha Jones, I'm one of the doctors on board. If you've any questions about what's going on here, I'm just one of the many people here who can help. If you've questions about the TARDIS specifically or the Doctor, I'm able to help specifically. As a note, as you may have noticed the TARDIS is sentient, there may be part of the ship she does not allow you into, please do not try to force the issue, she doesn't take well to it.
That out of the way, yes, we've landed. All scans show that food on the island follow Earth patterns - so if it was poisonous back home, don't eat it. Other than that all metrics: atmospheric, oceanographic, geographic, are similar to Earth if not identical. But as we are cutting through dimensions, please be cautious.
I've been able to determine that we are not doing any damage to the dimensional fabric of universes as we are passing through. The TARDIS' footprint is apparently not big enough to leave a permanent mark. I've set the systems to continue monitoring just in case.
Anyone who needs a change of clothing, feel free to raid the Wardrobe if the TARDIS hasn't left something in your rooms. Believe me there are enough clothes in there to outfit dozens of theatre companies.
