The Estuarine/Marine EHMP monitors a range of physical/chemical and biological indicators: water quality, seagrass depth range and distribution,  15N mapping, Lyngbya and coral. Click on the indicators to the right for more detailed information. |
|  | | | | | | Methods (190KB)  | | | Water quality is measured monthly at 254 sites and is comprised of physico-chemical parameters, dissolved and total nutrients, water clarity and phytoplankton abundance. Water quality information is collected to assess baseline ecosystem process and to track changes in the zones of human impact. | |
| | Methods (290KB) | | | Sewage nitrogen mapping assesses the extent of sewage treatment plant discharges into SEQ waterways through measurements of the uptake of the stable nitrogen isotope 15N by the macroalga Catenella nipae. | |
| | Methods (82KB) | | | Lyngbya majuscula is a toxic filamentous cyanobacterium found in tropical and sub-tropical marine and estuarine environments worldwide. | |
| | Methods (114KB) | | | Coral monitoring provides a measure of the change in biological structure of coral reefs in Moreton Bay annually. | |
| | Methods (114KB) | | | The seagrass depth range (SDR) is the difference in elevation (m) between the upper and lower depth record of the seagrass Zostera capricorni at a site. The distribution of seagrass in Moreton Bay is mapped every three years using a combination of remotely sensed images, underwater camera observation and visual estimation of seagrass cover. | |
| | Methods (138KB) | | | Riparian vegetation provides the interface between the land and a waterbody. The EHMP measures the extent of riparian habitat in the estuaries as the percentage of the total system that has retained unmodified riparian habitat. | |
