The operation of the Wastewater Treatment Plants and the discharge of treated wastewater to the marine environment is conducted under Licence Conditions set by the Department of Environment and Conservation. The Licence Conditions include requirements to: Measure treated wastewater flows and associated contaminant loads to ensure maximum nutrient loads are not exceeded; and Undertake an annual summer survey of ocean and beach water quality (nutrients, primary productivity and bacteria indicators) in the vicinity of the ocean outlets. This metadata record outlines all the annual reports from Perth Coastal Waters Study (1992) onwards. An indicative study area that includes PLOOM Summer Water Quality, Seasonal, Trial, Compliance, and Drogue Program Sites has also been compiled to provide a spatial reference to the work. Ocean Reef, Sepia, and Swanbourne are the location of these outlets.

'Seabase' is a fully relational on-line database which holds all the PLOOM (Perth Long-Term Ocean Outlet Monitoring), SDOOL (Sepia Depression Ocean Landline) and Bunbury Ocean Outfall water quality monitoring data, as well as data from the Perth Coastal Waters Study, the Alkimos Marine Studies Programme and the Metropolitan Desalination Plant Monitoring Programme.

The Lucinda Jetty Coastal Observatory (LJCO) is located on the end of the 5.8 km long Lucinda Jetty (18.52 S, 146.39 E) in the coastal waters of the Great Barrier Reef World Heritage Area close to the Herbert River Estuary and the Hinchinbrook Channel in Queensland. The observatory acquires continuous above and in-water optical measurements with the objective to support satellite ocean colour validation and algorithm development. Data collection and delivery was interrupted in 2011 with tropical cyclone Yasi. Currently, LJCO is the only southern-hemisphere ocean colour validation site integrated into NASA’s AERONET-OC global network of ground-based radiometers and one of a few sites globally that combines the acquisition of both atmospheric and in-water optical measurements. Mounted instruments on the LJCO included: - Met Station (Vaisala WXT520) - Above-water radiometry --- CIMEL SeaPRISM --- Satlantic HyperOCR --- DALEC instrument (added in mid-2016 for continuous hyper-spectral radiometric measurements) -Instrument telemetry --- Power supply --- UPS --- NextG Router --- WETLabs DAPCS --- PC controller --- Automated winch - Underwater optics --- WETLabs WQM --- WETLabs Eco Triplet --- WETLabs ac-s --- WETLabs BB9 - Campbell Scientific submersible pressure transducer The above-water measurements collected at LJCO compromise of multi-spectral water-leaving radiance and atmospheric observations for retrieving aerosol optical properties using an autonomous CIMEL SeaPRISM radiometer, in addition to hyper-spectral down-welling radiance measurements using the a Satlantic Hyper-OCR. In mid 2016 continuous hyper-spectral radiometric measurements were added using the DALEC instrument. The in-water optical measurements consist of conductivity, temperature, pressure, dissolved oxygen, chlorophyll fluorescence and turbidity using a WETLabs WQM, coloured dissolved organic matter (CDOM) fluorescence using a WETLabs EcoTriplet, as well as particulate and dissolved spectral absorption and attenuation coefficients using a WETLabs AC-S. Further, total backscattering coefficients are measured using a WETLabs BB9 radiometer. Additional meteorological and sea state measurements are continuously recorded such as barometric pressure, relative humidity, air emperature, wind speed and direction using a Vaisala WXT520 weather transmitter. Wave height and water temperature are measured with a Campbell Scientific submersible pressure transducer that is used to keep the caged in-water optical instruments at a constant depth. All data streams are processed in delayed-mode with automatic quality control applied and made publicly available through the AODN portal; and the data presented here is the daily in-water generated products.

Field-based sampling: As part of Australian Antarctic Science project # 4298, a total number of 44 sea ice sites were sampled for bio-optical measurements along 4 transects on land-fast sea ice off Davis Station (Antarctica) during November – December 2015. Measurements included simultaneous hyperspectral down-welling (ice surface) irradiance (triplicate) and under-ice radiance (triplicate) measurements (320 – 900 nm, 3.3 nm resolution) with a TriOS ACC and Trios ARC radiometer, respectively. The radiance measurements were conducted with the TriOS ARC radiometer mounted onto an L-shaped arm (for deployment details see Melbourne-Thomas et al. 2015). Subsequently, snow thickness was measured with a ruler and an ice core was collected directly above the radiometer location. Sea-ice freeboard (tape measure) and ice thickness (ice core length) were also recorded. Ice cores (9 cm internal diameter) were cut into sections, and these were melted in the dark at +4 degrees C, filtered onto GFF filters and then used to measure ice algal pigment content (using High Performance Liquid Chromatography (HPLC) and spectral ice algal absorption coefficients (ap, ad, aph) for entire vertical profiles or for the lower-most 0.1 m of ice cores. The location of the sampling grid had its origin (x=0, y=0) at GPS position: -68.568904, 77.945439. Transects (128m – 512 m in length) started at x=60, x=70, x=80 and x=90 m and were sampled at y-positions of 0m, 0.5m, 1m, 2m, 4m, 8m, 16m, 32m, 64m, 128m, (256m, and 512m) on 19/11/2015, 23/11/2015, 29/11/2015 and 02/12/2015, respectively. Analysis of ice algal chlorophyll a concentration: For pigment analysis, 0.25 to 1.0 litres of melted ice core subsamples were passed through 25 mm diameter glass-fiber (Whatman GF/F) filters. The filters were then frozen and stored below −80 degrees C prior to analysis using HPLC. Samples were extracted over 15 to 18 hours in acetone before analysis by HPLC using a modified C8 column and binary gradient system with an elevated column temperature [Van Heukelem and Thomas, 2001]. Pigments were identified by retention time and absorption spectra from a photo-diode array (PDA) detector, and concentrations were determined from commercial and international standards (Sigma; DHI, Denmark). Analysis of particulate (algal and non-algal) absorption: The optical density (OD) spectra of the particulate material on these filters (see section above) were measured over the 350 to 750 nm spectral range in 0.9 nm increments, using a Cintra 404 UV/VIS dual-beam spectrophotometer equipped with an integrating sphere. The pigments on the sample filter were then extracted using the method of Kishino et al. [1985]'s method to determine the OD of the non-algal particles in a second scan. The OD due to ice algae was then obtained by calculating the difference between the optical density of the total particulate and non-algal fractions. The OD measurements were converted to absorption spectra using blank filter measurements, and by first normalizing the scans to zero at 750 nm and then correcting for the path length amplification using the coefficients of Mitchell [1990]. A detailed description of the method is given in Clementson et al. [2001], and followed SeaWiFS protocols [Muller et al., 2003]. An exponential function was fitted to all spectra of non-algal particulate material: ad(λ) = ad(350 nm) exp[−S(λ − 350 nm)] + b, (1) where ad(λ) is the residual absorption coefficient over the wavelength (λ) range 350 to 750 nm of the particles after methanol extraction, also referred to as absorption of detritus [m−1] although this may include absorption of non-extractable pigments and heterotrophic protists. A non-linear least-squares technique was used to fit Equation 1 to the untransformed data, where S and b are empirically-determined constants. The inclusion of an offset b allows for any baseline correction. In some samples, pigment extraction was incomplete, leaving small residual peaks in
