Depth-related cycling of suspended nitrogen-containing lipids in the northeast Atlantic
We utilized high resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) to describe the depth-dependent distribution and molecular nature of nitrogen containing lipids (N-lipids) from suspended particles in an oceanic environment. Samples were collected at the Porcupine A...
