Data from: A compendium of geochemical information from the Saanich Inlet water column

Marine oxygen minimum zones (OMZs) are widespread and naturally occurring
water column features that constitute ~7% of global ocean volume, but
contribute disproportionately to biogeochemical cycling of carbon,
nitrogen and climate active trace gases such as nitrous oxide and methane.
Climate change compounded by other human activities is causing OMZ
expansion. While microbial communities are the primary engines driving
biogeochemical cycles in OMZs, our current understanding of microbial
community metabolism is hindered by a lack of time-series observations
charting responses to changing water column oxygen-deficiency. Saanich
Inlet, a seasonally anoxic fjord on the coast of Vancouver Island British
Columbia is a model ecosystem for monitoring microbial community
structure, function and dynamics in relation to changing levels of water
column oxygen-deficiency extensible to coastal and open ocean OMZs. Here,
we present nine years of monthly time series observations in Saanich Inlet
encompassing water column chemistry and environmental sequence
information. This compendium provides a unique ecological and
biogeochemical framework for comparative community analysis and modelling
efforts in OMZs throughout the global ocean.
