RAN CTD Profile Data - HMAS MELVILLE ProjectID: HI548MEL_M From: 2013-10-14 To: 2013-11-12

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 409 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI548MEL_M from HMAS MELVILLE.
The CTD was manufactured by Applied Microsystems Limited and is the "Micro CTD" model. This CTD type is referred to operationally as the MVP200_CTD. This CTD is fitted with a 4 electrode platinized conductivity cell, thermistor temperature sensor and a semiconductor strain gauge pressure sensor.
The CTD sensors are calibrated at the manufacturer Applied Microsystems Limited on a 12-18 month schedule. The CTD temperature sensor is calibrated against 'Hart' temperature standards. The pressure sensor is calibrated using 'Budenburg Deadweight' standards. The conductivity sensor is calibrated using 'Hart' temperature standards and seawater samples of known conductivity.
The CTD sensors are mounted to a fish-shape probe. The probe is controlled by an electric winch (MVP200 type). For downcasts the fish is allowed to free-fall (winch is in 'free-wheel' mode) under its own weight at about 2-3 ms-1 and then is winched back. Data is recorded in downcast and usually in upcast direction at a sampling rate of 25 Hz. The downcast data is of higher quality because sensors encounter undisturbed seawater that flows through the nose of the fish. On the upcast the fish is flipped around (tail first) and the sensors in the nose encounter disturbed flow from the fish tail.
This type of CTD is prone to a phenomenon called 'salinity spiking' caused by a mismatch between the response times of the temperature and conductivity sensor. Data undergoes a salinity de-spiking routine to correct for this. See the history metadata for further details on the salinity de-spiking process.
Raw CTD pressure data is not always monotonic due to transient up/down motion of winch/ship. Raw pressure data is subsetted to give a monotonic (increasing) sequence and then linearly interpolated to 1 decibar pressure intervals. Data is then flagged with quality control flags after visual inspection and comparison to average climatology and historical CTD casts.

Significance of Halimeda bioherms to the global carbonate budget based on a geological sediment budget for the Northern Great Barrier Reef, Australia

Since the correlation between carbon dioxide levels and global temperatures was established in the ice core records, quantifying the components of the global carbon cycle has become a priority with a view to constraining models of the climate system. The link between the marine carbonate budget and atmospheric CO2 levels draws attention to the fact that this budget is still not adequately quantified. 
It is widely accepted that the calcareous green alga Halimeda is a prominent contributor of carbonate to reef sediment facies in the tropics, however, Halimeda bioherms remain one of the main reservoirs of unaccounted for carbonate. In fact, it has been suggested that Halimeda bioherms on the shelf of the Northern Great Barrier Reef may contain an equal or greater volume of carbonate than the reefs themselves.
Here we attempt to determine the quantitative relationship between Halimeda bioherm and coral reef derived carbonate accumulated during the Holocene on the outer shelf of the Northern Great Barrier Reef Province using data from seismic profiles, reef drill cores and Halimeda bioherm piston and vibrocore cores from the published literature. 
The methodology used is detailed in the document availble for download through this record.
Calculations reveal that the ribbon reefs of the Lizard Island and Cooktown regions cover areas of approximately 18.5 and 20.5 km2 and comprise approximately 0.52 and 0.92 Gt CaCO3 respectively. The Halimeda bioherms of the Lizard Island and Cooktown regions cover areas of approximately 184 and 118 km2 and comprise approximately 2.06 and 0.86 Gt CaCO3 respectively. 
Thus, that ratio of ribbon reef to Halimeda bioherm CaCO3 is approximately 1:4 and 1:1 for the Lizard Island and Cooktown regions respectively. If we assume that the carbonate content of the Lizard Island region bioherms ranges from 20 to 90 %, we estimate that the mass balance of Halimeda bioherm CaCO3 is between 0.55 and 2.5 Gt. The ratio of ribbon reef to Halimeda bioherms CaCO3 may vary between 1:1 to 1:5 depending on the carbonate content of the Lizard Island bioherms.

Ocean temperatures over time estimated from planktonic foraminifera assemblages in core MD002361 located on the shelf edge off Western Australia. Estimates are provided for the sea-surface, 50m, 100m, and 150m

In recent years the term 'enhanced greenhouse effect' has become well known in modern society and yet aspects of this possible 'future climate' are poorly understood. The characteristics of the geological record provide a basis to understand this possible future climate through the examination of alternating glacial (cold) and interglacial (warm) stages. Understanding the variability of sea-surface temperature and biological processes in the water column provides insight into general circulation of present and paleo-ocean currents. At a core site off Western Australia (MD002361, 113.477166 E, 22.082 S) the highest annual SST estimate (Tmean) of 29.1oC ± 0.84oC was recorded during MIS 5, 1.6oC warmer than the modern recorded Tmean. Most interglacial periods were equivalent or warmer than present apart from Marine Isotope Stage (MIS) 7. The most extreme glacial to interglacial transition was from the penultimate glacial period (MIS 6) to the last interglacial (MIS 5) with a temperature range of 8.7oC ± 0.84oC. The mixed layer is also thinner during interglacial periods compared to the glacial periods.

Temperate Australian quantitative spatial and temporal abundance data for rocky reef biota (biodiversity): Esperence to Albany (WA)

The data is quantitative abundance of fish and megafaunal invertebrates and algal % cover derived from transect based counts at a wide range of locations across Temperate Australia. The methods are described in detail in Edgar and Barrett (1997). Primarily the data are derived from transects at 5 m depth and/or 10 m depth at each site surveyed. Methods were initially developed for research on temporal changes following protection in Tasmanian MPAs (Maria Is, Tinderbox, Ninepin Point, Governor Island). The data represented by this record was collected in MPA studies and surveys interstate, and was collected from Esperence to Albany (WA). In many cases the dataset involved temporal replication (year scale).

Fast Repetition Rate Fluorometry (FRRF) data collected on the RV L'Astrolabe from 19/02/2003 to 24/02/2003 (Hobart - Dumont d'Urville)

These data were collected on the RV L'Astrolabe (platform code: FHZI) from 19/02/2003 to 24/02/2003 on a trip from Hobart to Dumont d'Urville.
Maximum photochemical efficiency of photosystem II (PSII), also called maximum quantum yield of PSII (Fv/Fm), has become one of the most widely utilized fluorescence parameters in phytoplankton research. It represents the potential photochemical efficiency, which is the probability that the light energy captured by the photosynthetic apparatus is being utilized as photochemistry. Fv/Fm has been shown to have an instant response to variations in physical and chemical properties and is interpreted as a diagnostic of the overall health or competence of phytoplankton. Together with the absorption cross section area of PSII and chlorophyll concentration, it can be used to measure primary production (Cheah et al. 2011, Deep Sea Research).
Seawater from 3 m depth was supplied continuously from the ship’s clean seawater line. FRR fluorescence yields were measured continuously at 1 minute intervals in dark-adapted state (! 15 minutes dark-adaptation) using a flash sequence consisting of a series of 100 subsaturation flashlets (1.1 μs flash duration and 2.8 μs interflash period) and a series of 20 relaxation flashlets (1.1 μs flash duration and 51.6 μs interflash period).

Seeps of Heywood Shoals

Using a towed camera we assessed the substrata around seeps identified by Geoscience Australia. Five towed video transects were undertaken between 0900 and 1200hrs on 8/11/2004, in water depths of between 77 and 92m. While the RV Cape Ferguson?s echo sounder showed the potential seeps, there appeared to be little of interest on any of the video tows. There was no noticeable change in the substratum (sediment type, hardness etc) or the visible biological community around the identified seeps. Potentially our video tow gear could have missed the seeps as they are only 5-10 metres across. However the echo sounder did suggest we towed directly over several seeps. Video footage of each tow is held by AIMS WA.
