We present a technique that utilises a segmented flow coil equilibrator coupled to a proton-transfer-reaction mass spectrometer to measure a broad range of dissolved volatile organic compounds. Thanks to its relatively large surface area for gas exchange, small internal volume, and smooth headspace–water separation, the equilibrator is highly efficient for gas exchange and has a fast response time (under 1 min). The system all...

We present an 8‐yr time‐series of monthly water column N 2 O measurements from Saanich Inlet, a seasonally anoxic fjord in southern British Columbia. We document seasonal and inter‐annual variability in N 2 O concentrations driven by physical and biological forcing, and examine the relationship between N 2 O and O 2 concentrations across the redoxcline in this system. Near‐surface N 2 O concentrations were typically supersatur...
