Macquarie Harbour Dissolved Oxygen and Temperature Monitoring Data - HOBO loggers - 04-06-2017 to 11-12-2018
This dataset consist of dissolved oxygen (DO) and temperature data collected using HOBO Dissolved Oxygen loggers (U26-001) under FRDC project 2016-067. Loggers are deployed on strings in two locations in Macquarie Harbour, Tasmania.
This dataset consists of data collected by the real-time dissolved oxygen (DO) monitoring system in Macquarie Harbour, Tasmania, originally established under the Sense-T program, continued under FRDC project 2016-067 and deployed and maintained by IMAS. The system consists of 3 strings of acoustically telemetered, optical fluorescence DO, temperature and depth sensors (VEMCO, Bedford, Canada) which measure DO in % saturation, temperature in °C and depth in meters. The dataset spanning the time period from the 1st of January 2017 to the 19th of April 2017 consists of data collected using the first generation of sensors as described above. Subsequent quarterly updates from the 3rd of June 2017 onwards consist of data collected using the new generation of tags which contain a tilt instead of a depth sensor.
These data describe quantitative exposure indices generated using cartographic fetch methods on a 0.01 degree grid across temperate Australia (South Australia, Victoria and Tasmania). Two indices are reported: openness and bathymetry-altered fetch. Openness is a measure of the distance of a site to the nearest coastline in all directions and describes potential exposure to locally generated seas and undefined swell. Bathymetry-altered fetch attempts to account for the attenuation of wave energy as waves move into shallow waters and encounter friction with the seafloor.
