Year 2014, continuous measurements every 15 minutes were made of dissolved oxygen, water temperature in Cart Creek, Newbury, MA, a small headwater stream draining a mainly forested catchment (55% forest + 19% wetland) in the Parker River watershed.
Dissolved oxygen and water temperature were measured using a HOBO datalogger attached to the outside of a PVC pipe in the center of the stream channel.
Dissolved oxygen percent saturation was calculated using HOBOware software and barometric pressure data from a HOBO pressure transducer located at Wednesday Hill Brook in the Lamprey River watershed, in Lee, NH. Barometric pressure data are typically collected at the MBL Marshview Farm Field Station in Newbury, MA however due to instrument failure, barometric pressure data from Wednesday Hill Brook, 45 km north of Marshview, were used.
ADDITIONAL RESEARCH LOCATION COORDINATES:
In addition to the decimal degree coordinates given above, locations are also given here in Massachusetts State Plane coordinates. The stream is called Cart Creek and is located in Newbury MA. Some residential area is present (~10% of the basin). In addition, I-95 passes through the center of the catchment, resulting in roughtly 8% impervious surface area. Beaver have also been actively present since roughtly the mid-2000s and have created a number of impoundments spanning the length of the stream.

NOTES AND COMMENTS:
HOBO dissolved oxygen loggers have a sensor cap that requires replacement every 7 months. If the logger is deployed when the sensor cap expires, no usable data is collected after that point.
1 -- Datalogger not deployed
2 -- Datalogger was deployed but with an expired sensor cap
