Brief description
Fixed position oxygen and water temperature logger data from the Macquarie Harbour World Heritage Area (WHA). Two Hobo oxygen data loggers are positioned at approximately 15 m depth at different sites within the WHA, with the intent of monitoring representative mid-bottom water oxygen values in the WHA as these were identified in previous studies to be naturally low due to limited seawater exchange at the harbour entrance, and thus likely to be most susceptible to anthropogenic factors that may increase oxygen demand and alter WHA conservation values. These values include core habitat of the Maugean Skate, a listed threatened species. This work is funded by WHA advisory board via the Nature Conservation Branch of DPIPWE and is part of a larger study being conducted by IMAS undertaking a biological baseline study of the biodiversity of the Macquarie Harbour WHA.This data spans 08/11/14 to present (most recent update 02/02/17).
Lineage
Maintenance and Update Frequency: annually
Statement: Hobo oxygen logger data collecting oxygen and temperature data at half hourly intervals. Instrument id the Hobo Dissolved Oxygen Logger U26-001 (http://www.onsetcomp.com/files/manual_pdfs/15603-B-MAN-U26x.pdf). Instrument calibration was conducted prior to deployment, at three months, and at seven months with new cap added at seven months and recalibrated. Data are uncleaned so include pre-deployment air and surface values, surface values at initial retrieval, download and redeployment (3 months), and at seven months redeployment and cap change.
Note that logger data of this nature does contain occasional spikes, and that significant outliers would normally be removed prior to any data analysis.
