Temperatures there are rising at twice the global rate, sparking an array of changes unlike anything in recorded history. One of the most striking examples is the region's sea ice, whose dramatic decline over the past decade has led to forecasts of an ice-free Arctic Ocean as early as the 2030s. .

The images presented are animals that are experiencing worrisome declines in populations. Most of the declines are the result of human action and most often at least partially due to climate change (e.g., see: .

Water samples collected over six years from major Arctic rivers (. www.arcticgreatrivers.org. ) were analyzed using the MagLab’s record-setting 21T ultra-high-resolution Fourier-transform ion cyclotron resonance mass spectrometer. This magnet system’s resolving power is capable of determining elemental composition for tens of thousands of individual molecules in a single water sample. Combined with isotopic data, these formulae revealed both a common core amongst samples, as well as unique tracers of seasonality and a changing Arctic. .
