Northeast of the Forward Station near the Techiix Station you’ll find a platform, whereupon you’ll find the biologists that’ll give you the quest "The Lost Song". There are also some other, apparently less-interesting seeming armed Angara, but if you head northeast along the ice from this platform an Angara named Orev will ask you to help him lure out a Wraith. This starts the quest "Task: White Death".
To complete this quest, simply continue east, northeast to find a search area, then play "hot/cold" until you get full search bars. Once done bring up your scanner, scan the Wraith, and wait for the Angaran sniper to take it out, which is worth 270 XP When it’s dead, return to Orev to complete this quest, which will net you another 270 XP.
