Quantitative waterbird surveys over seasonal wetlands of the Alligator Rivers Region (ARR) of the NT, provided by the Supervising Scientist Division (SSD) of the Commonwealth Department of the Environment, Water, Heritage and the Arts (DEWHA). Ground and aerial surveys at 17 billabongs within the Magela Creek catchment. Environmental information includes structural classification of each billabong surveyed

Quantitative waterbird surveys over seasonal wetlands of the Alligator Rivers Region (ARR) of the NT, provided by the Supervising Scientist Division (SSD) of the Commonwealth Department of the Environment, Water, Heritage and the Arts (DEWHA). Systematic aerial survey, conducted monthly from June 1981 to August 1984. Environmental information on dominant cover types is also included (Wet Plain, Dry Plain, Wet Melaleuca, Dry Melaleuca, Open Water, Dry Woodland, Mud).

Aerial survey of waterbirds and wetlands in eastern Australia. All waterbird species in ten 30 km wide survey bands are counted, on waterbodies >1ha in size; ; Project was initiated by CSIRO and NSW NPWS and jointly funded by State wildlife agencies of Vic, Qld, SA and NSW. From 2005 project management was transferred to the University of New South Wales.

The National Oceanic and Atmospheric Administration (NOAA) has the statutory mandate to collect hydrographic data in support of nautical chart compilation for safe navigation and to provide background data for engineers, scientific, and other commercial and industrial activities. Hydrographic survey data primarily consist of water depths, but may also include features (e.g. rocks, wrecks), navigation aids, shoreline identification, and bottom type information. NOAA is responsible for archiving and distributing the source data as described in this metadata record.

Accurate elevation data in coastal wetlands is crucial for planning for sea-level rise. Elevation surveys were conducted across southwest Florida wetlands to provide ground validation of LiDAR as well as target long-term monitoring stations (surface elevation tables). Surveys were conducted in June 2021 across Ding Darling National Wildlife Refuge, Clam Bay, Rookery Bay National Estuarine Research Reserve, and Ten Thousand Islands National Wildlife Refuge. A combination of post-processed kinematic GPS and differential levelling survey techniques were employed, depending on the canopy cover.

To relate water levels in our study wetlands to temperature, precipitation, wetland water depth, and amphibian calling activity, we installed one pressure logger in the deepest spot we could find in each wetland. Soon after thawing conditions allowed, we drove a plastic pipe (anchor pipe) into the sediments at the deepest location and secured another pipe to it that contained one pressure logger (Global Water Model 14 and 15 [College Station, TX, USA] or Onset Computer Corporation Model U20-001-04 [Bourne, MA, USA]) suspended approximately 2.5 cm above the sediments. We installed additional individual pressure loggers in the upper part of the logger pipes (in air) at select locations to measure barometric pressure for calibrating the submerged loggers’ readings. We measured pressure once per hour and used software supplied by the logger manufacturers to upload and convert data to depth at the end of each season.

A total of 159 wetlands were monitored on and off between 1977 and 2019 as part of the Southwest Wetland Monitoring Program, by the Department of Biodiversity Conservation and Attractions (DBCA) and its predecessors. Details of the monitoring program and the results can be found in Lane et al., (2017) and references therein (J.A.K. Lane, A.G. Clarke & Y.C. Winchcombe, 2017. South west wetlands monitoring program, 1977-2016. Department of Biodiversity Conservation and Attractions https://library.dbca.wa.gov.au/#record/142545). The data consists of a table of wetland site information, a table of water level and water quality measurements and a file describing the tables columns.
