This metadata record describes chlorophyll fluorescence and turbidity time-series data collected through in situ monitoring by the Great Barrier Reef Marine Monitoring Program for Inshore Water Quality (MMP WQ). A full description of the MMP WQ and its associated datasets can be found in the parent metadata record linked above. Continuous in situ chlorophyll fluorescence and turbidity were measured using WET Labs ECO FLNTUSB Combination Fluorometer and Turbidity Sensors. The MMP WQ currently has instruments deployed at 19 sites summarised by Natural Resource Management (NRM) region below. The date ranges of instrument deployments are also shown; some sites were discontinued in 2014 but data are still available for download. Cape York NRM: Annan-Endeavour focus region: Forrester Reef (2020-present), Dawson Reef (2020-present) Wet Tropics NRM: Barron-Daintree focus region: Snapper Island North (2007-2014) Russell-Mulgrave focus region: Fitzroy Island West (2007-present), High Island West (2007-present), Russell-Mulgrave River mooring (2015-present), Frankland West (2007-present) Tully focus region: Dunk Island North (2007-present), Tully River mooring (2015-present) Burdekin NRM: Pelorus (2007-present), Pandora (2007-present), Geoffrey Bay (2007-present), Burdekin River mooring (2015-present) Mackay Whitsunday NRM: Double Cone Island (2007-present), Daydream Island (2007-2014), Pine Island (2007-present), Seaforth Island (2015-present), Repulse Island dive mooring (2015-2021), O'Connell River mooring (2021-present) Fitzroy NRM (monitored 2005-2014 under MMP WQ, 2020-present under Fitzroy Basin program): Pelican Island (2007-2015), Humpy Island (2007-2015, 2021-present), Barren Island (2007-2015, 2021-present), Fitzroy River mouth (2021-present). Instruments are deployed for approximately 4 months at a time at 5 m below the water's surface. They collect one sample every 10 minutes, where each data point is calculated as the mean of 50 instantaneous burst readings. Pre- and post-deployment checks of each instrument include measurements of the maximum fluorescence response and the dark count (instrument response with no external fluorescence, essentially the ‘zero’ point). Factory servicing and calibration checks are performed at the WET Labs facility in the USA after 12-18 months of in-water deployment time. After retrieval, the instruments are cleaned and data downloaded and converted from raw instrumental records into measurement units (µg L-1 for chlorophyll fluorescence and NTU for turbidity) according to the standard procedures of the manufacturer. Deployment information and all raw and converted instrumental records are stored in an Oracle-based data management system developed by AIMS. Detailed procedures for data handling can be found the MMP WQ's QA/QC Reports (see link below in Related Information). Instrument data are validated against concurrently-collected water samples. Water samples for analyses of chlorophyll a and total suspended solids are collected three times per year to calibrate logger fluorescence and turbidity to in situ conditions. Diver-operated Niskin bottles are used to sample close to the moored loggers and samples are preserved and analysed in the same manner as ship-based water samples (see link below in Related Information). Instruments in the Cape York region are deployed at 3 m below the surface and have different processing and servicing procedures than other regions. These procedures are detailed in the files containing instrument data, linked below. Instrument data can be downloaded in hourly or daily averaged formats (see links below in Data Downloads).

Five sites within Cleveland Bay were instrumented with Wetlabs NTU (turbidity), LiCor PAR (light as PAR) and Diver CTD instruments with monthly data download and collection of water samples for TSS analysis. Instruments were deployed in September 2014 and removed in August 2017 under a contract with the Port of Townsville Limited (PoTL).The work was to understand background and dredging turbidity within the bay. Sites were located in the eastern part of the Bay (JCU Seagrass Watch site 'Meadow-19' = Site CB), at Florence (Site FB), Geoffrey (Site GB) and Picnic Bays (Site PB) around magnetic Island and at Virago Shoals (Site VS) off Pallarenda.Data from the Cleveland Bay AIMS weather station were also provided along with MMP data for Picnic Bay. To monitor background levels of turbidity (as NTU and underwater light) in the Bay and to provide information on potential impacts of maintenance dredging on turbidity levels at sensitive receptor sites (Coral Reefs - Florence, Geoffrey and Picnic Bays, Seagrass - Virago Shoals and Meadow-19). Data was collected from September 2014 through to August 2017,

This research monitored inshore island fringing reef communities, including fish and benthos, for over 20 years in the Palm, Magnetic, Whitsunday and Keppel Island groups, to better understand the effects of marine park zoning on these reefs. It is the only large-scale, long-term dataset on the inshore Great Barrier Reef that includes fish assemblages as well as benthic communities. The data were initially collected to inform the Great Barrier Reef Marine Park Authority about the effects of no-take (green) zones on fisheries target species, along with other fish species and benthic assemblages. The monitoring began in 1999 in the Whitsundays, subsequent years in other island groups, and ended in 2019. Elements were added as the surveys progressed, and the entire fish assemblage captured in this analysis was surveyed from 2007 onwards. The surveys were conducted by SCUBA divers using underwater visual survey for fish and point intercept transects for benthos, with five 50m transects at each site. We are analysing this dataset using boosted regression tree models that test the influence of different predictor variables on the fish assemblage.

This dataset contains meteorological and light data from the weather station located on Bramble Cay in the northern part of the Torres Strait. The station was installed under funding from the National Environmental Science Programme (NESP) Tropical Water Quality Hub under Projects 2.2.1 and Project 5.14 with support from the Torres Strait Regional Authority (TSRA). These data are collected to support scientific research. Data are made available on request to other researchers and to the public as well as being available from the AIMS web site. This weather station is funded by NESP with support from the Torres Strait Regional Authority (TSRA). The weather station is an AIMS Mk5 system consisting of a Vaisala WXT520 weather station and a LiCor 192 Light Sensor. The system has seperate underwater sensors that are logged (and so not transmitted in real time). These sensors include a WetLabs NTUS turbidity sensor and a SeaBird SBE37 CDT (Condutivity (salinity), Temperature and Depth) located just off the Cay in 3m of water. Note that this station is located on land and has NO in-water sensors. Data recorded: Barometric Pressure, Air Temperature, Humidity, Solar Radiation (PAR), Wind Direction True (vector averaged), Wind Speed True (30 min average), rain duration and rate, precipitation amount. The weather stations collect and store data in electronic memory every ten minutes, the station uses the 3G phone network to send the data to AIMS where it is stored in a database and then made available via the web and other systems. The data are then checked for accuracy using a number of range and historical checks, longer term summeries are then calculated along with indicies of potential thermal stress.

Biological oceanographers from the Australian Institute of Marine Science (AIMS) have studied the physical, chemical, and biological properties of seawater around northern Australia using a variety of methods including in situ sampling, moored sensors, and vertical profiles. This metadata record describes vertical profiles of physico-chemical data collected by researchers from the from 1974 until the present. Vertical profiles are important tools that oceanographers routinely use to understand ocean structure. These profiles are collected using a Conductivity, Temperature and Depth (CTD) profiler, which is lowered on a steel cable from the water’s surface to close to the seafloor. Niskin bottles can also be attached to the CTD (in a rosette) or used independently to collect water samples from different depths for analysis. AIMS uses Sea-Bird Electronics CTD profilers, which are typically fitted with additional sensors to measure parameters such as fluorescence (a proxy for chlorophyll a concentration), turbidity, beam attenuation, dissolved oxygen concentration, and photosynthetically active radiation (downwelling light) sensors. Instrument models SBE 19plus and SBE 19plusV2 are used currently, while older records include data from SBE 25, SBE 25plus, and SBE 9plus instrument models. Annual calibrations of profilers are carried out in Sea-Bird Electronics laboratories in the USA. These calibration values are included within the instrument configuration file. Pre-trip CTD checks are carried out before each field trip, which include checking the physical status of the sensors and cables and battery voltage. Prior to conducting a cast, the CTD is secured to the hydrographic wire, tubing is removed to allow flush water to drain from the conductivity-temperature cell, and any protective caps are removed from the other sensors. The CTD is lowered into the water sitting ~3 m below the surface, and a three minute "soak" allows sensors to equilibrate and air bubbles to be flushed by the pump. The CTD is then raised to ~0.2 below the surface and the profile is commenced at a rate of 0.5 – 1 m s-1. The CTD is sent to near-bottom, ensuring it does not touch the seafloor, and retrieved to the surface. Casts are done on the sunny side of the boat to avoid the boat's shadow interfering with the measured light profiles. Data processing is conducted using Sea-Bird proprietary software and includes: conversion of raw instrumental records to measurement units, alignment, removal of ship roll, outlier removal, and bin averaging the down-cast at 1 m increments. Further details of CTD data handling can be found in the Quality Assurance and Quality Control Manual from the Marine Monitoring Program (see link below in Related Information). CTD data can be downloaded from this record (see link below in Data Downloads). Each CTD cast occurs at a unique combination of geographic location, time, and date. In the AIMS database, each cast is assigned a unique alphanumeric identifier (called a ‘station’), which is comprised of a 3-letter area code and a 3-digit station number (e.g. WQM324). Using this code, water chemistry measurements taken at the time of the CTD cast can be retrieved from AIMS’ water quality database (see link below in Related Information). Some data in this record were collected as part of the Great Barrier Reef Marine Monitoring Program for Inshore Water Quality, which has its own metadata record (see link below in Related Information).
