Geospatial and Data Services Manager - Wilson Inlet Seagrass Survey - Cover (DWER-114)
공공데이터포털
Wilson Inlet was surveyed in December 2017, April 2018, December 2019, December 2020, December 2021 and December 2022 by underwater drop camera observations and/or observations through a viewing cone. Seagrass distribution and cover (as percentage cover in categories: 0, 0-10%, 10-25%, 25-50%, 50-75%, 75-90%, 90-100%) were recorded. The canopy height (in 10 cm intevals) and epiphytic cover (as low, medium, high) was also estimated. Macroalgae distribution and cover (as percentage cover in categories: 0, 0-10%, 10-25%, 25-50%, 50-75%, 75-90%, 90-100%) were recorded. At approximately a third of the sites, physical water profiles, photosynthetically active radiation (euphotic depth), and secchi depth were recorded.

Sediment Data for Tasman Peninsula, Tasmania
공공데이터포털
Geoscience Australia carried out marine surveys in south-east Tasmania in 2008 and 2009 (GA0315) to map seabed bathymetry and characterise benthic environments through observation of habitats using underwater towed video. Data was acquired using the Tasmania Aquaculture and Fisheries Institute (TAFI) Research Vessel Challenger. Bathymetric mapping was undertaken in seven survey areas, including: Freycinet Pensinula (83 sq km, east coast and shelf); Tasman Peninsula (117 sq km, east coast and shelf); Port Arthur and adjacent open coast (17 sq km); The Friars (41 sq km, south of Bruny Island); lower Huon River estuary (39 sq km); D Entrecastreaux Channel (7 sq km, at Tinderbox north of Bruny Island), and; Maria Island (3 sq km, western side). Video characterisations of the seabed concentrated on areas of bedrock reef and adjacent seabed in all mapped areas, except for D Entrecastreaux Channel and Maria Island. Seabed sediment samples were collected by TAFI in August 2010 in a targeted area to the east of Tasman Peninsula. Samples were collected at 25 stations using a Van Veen grab, from which a 50 - 100 g sub-sample was taken and submitted to Geoscience Australia for analysis. This dataset is a contribution to the CERF Marine Biodiversity Hub.

Port MacDonnell Coastal Station Data 1973-1981
공공데이터포털
This dataset contains oceanographic data collected at a 50m coastal station off Port MacDonnell, South Australia (lat. 38 deg. 10 min. S, long. 140 deg. 41 min. E) from May 1973 to October 1981. The station was set up under the CSIRO coastal monitoring programme in the 1970s and was sampled approximately monthly (weekly at some times) for temperature, salinity, dissolved oxygen and nitrate. The data are stored on-line as part of the CMR hydrology archive in Hobart. Additional copies of the data are deposited with the NODC data archive (World Data Centre-A) in the U.S.A., and details of relevant data files can be viewed via their website by requesting the file inventory for this coastal station which is NODC platform code "09Q8".
