Sediment oxygen demand in shallow water habitats around the Chandeleur Islands in 2015 and 2016

Oxygen consumption rates and environmental variables were measured with field-deployed metabolism core chambers in various sites around the Chandeleur Islands in the Fall and Summer of 2015 and 2016. Each chamber consisted of a 15.24 cm diameter (20.32 cm length) acrylic tube, capped at the top with a custom-built fitting for water stirring and HOBO logger placement. For each chamber deployed, dissolved oxygen and water temperature data were collected from within the chamber. Light meters were deployed in parallel with the chambers to detect ambient light penetration into the water column. From these data, sediment oxygen consumption (mmol O2/m2/day) was calculated. These measurements can be correlated with average temperature, light, time of day, habitat type, site, and sampling season. These data can also be associated with infaunal abundances and characteristics in a related dataset (GRIIDC UDI: R4.x262.000:0010).
