Fast Repetition Rate Fluorometry (FRRF) data collected on the RV L'Astrolabe from 22/01/2003 to 27/01/2003 (Dumont d'Urville - Hobart)

These data were collected on the RV L'Astrolabe (platform code: FHZI) from  22/01/2003 to 27/01/2003 on a trip from Dumont d'Urville to Hobart.
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).

Mortality of the gastropod Lepsiella vinosa on the West Head rocky shore in Victoria

This study investigated mortality of egg capsules, juveniles, and adult Lepsiella vinosa on the rocky shore at West Head, Victoria. Observations conducted between 1974 and 1979 indicated that polychaetes, nematodes, nemerteans, planarians and mollusks all prey on L.vinosa egg capsules. It was estimated that at least 43% of embryos found over the study period did not hatch.  
To estimate juvenile mortality, an area of about 0.5 m2 of shingle beach immediately above the rocky shore was excavated to a depth of 15 cm on 21 July 1978. The shingle was sieved through a series of sieves with the smallest size being 1.00 mm. There were 220 empty L.vinosa shells found in the sample and the majority was between 9.5 and 14.0 mm long. A size-frequency distribution of L.vinosa shells was used to estimate the age of death for each individual. The causes of juvenile and adult morality were probably predation by crabs (e.g. Carcinus maenus) and adverse environmental conditions associated with tide emersion periods and desiccation. The results indicated that juvenile mortality is generally low in the first 3 years after hatching and steadily increases throughout the remainder of the life span (up to 10 years). 
There was no L.vinosa found in the gut contents of the parrotfishes P.fucicola or P.tetricus. Observations of the study area during high tide periods suggested that no other species of fish or bird prey on L.vinosa at West Head.

RAN CTD Profile Data - HMAS SHEPPARTON ProjectID: HI558SHE_M From: 2014-10-17 To: 2014-11-28

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 224 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI558SHE_M from HMAS SHEPPARTON.
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.

Ocean temperatures over time estimated from planktonic foraminifera assemblages in core BAR9403 located off the coast of Sumatra. 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. The core obtained offshore from Sumatra (BAR9043, 104.0316E, 5.82S) highlights an upwelling signal at 14,000 yrs BP that disrupts the warm stratified water column, which was a feature between Marine Isotope Stage (MIS) 3 to present. This upwelling is timed to a regional pattern of an intensified Australasian Monsoon.

Derwent Estuary Ambient Water Quality monitoring program - Site NTB-5

Site NTB-5 is sampled monthly by Nyrstar Hobart as part of the  Derwent Ambient Water Quality monitoring program.
Since 2003, ambient water quality monitoring has been carried out on a monthly basis at up to 28 sites throughout the Derwent estuary by Norske Skog Boyer, Nyrstar Hobart and the State Government. Monitoring is carried out by three different boat-based sampling parties, but is co-ordinated to occur on the same day each month. 
At each site, in-situ field measurements are taken using calibrated sensors for temperature, salinity, pH, dissolved oxygen and turbidity. Water clarity is also measured using a secchi disk. Surface and bottom water samples are collected for analysis of true color, total suspended solids(TSS), total  and dissolved nutrients, organic carbon and zinc. at most sites, depth integrated samples are also collected for chlorophyll a using a plastic tube. Bottom samples in the Middle and Outer estuary are collected using a niskin bottle. Pumps are used in the upper estuary site to fill up the bottles. All water samples are analysed at Analytical Service Tasmania, a National Association of Testing Authorities-accredited laboratory. Monitoring site depth is 2 meters

SAIMOS - Biological and Flow Cytometry data collected from CTD stations in South Australia, in October 2008

Flow cytometry data was collected in October 2008, in waters off South Australia. 
The general purpose of the study is to be able to establish background knowledge on the ecosystem on the continental shelf of South Australia and the impact of upwelling/saline outflow events on microbial communities to ultimately develop a biogeochemical model of the region. Sampling was carried out during cruises conducted on board the RV Ngerin as part of the Southern Australian Integrated Marine System (SAIMOS). During each cruise, the physical, chemical and biological properties of the chlorophyll fluorescence maximum (FM) layer were investigated. Flow cytometry data has been collected for picophytoplankton, bacteria and viruses.
Six main stations have been sampled over the course of the study, five are located on the 100 m isobath, i.e. RS (35.508S, 136.278E), B2 (35.418S, 136.148E), B3 (35.258S, 136.048E), B4 (35.168S, 135.418E) and B5 (35.008S, 135.198E), and one from an offshore station (B1; 36.188S, 136.178E) located southwest of Kangaroo Island. Note that combining the distances between stations (14–25 nautical miles), the average component of the current velocity at middepth along the shelf (0.01 m s21) and the average speed of the vessel (i.e. 9 knots) indicate that different water masses were sampled at each station. Additional samples have on occasion been collected from the National Reference Station (NRS) at Kangaroo Island (35.832S, 136.447E) and the SA Spencer Gulf Mouth Mooring (SAM8SG, 35.25S, 136.690E), where the saline outflow occurs.

Southern Great Barrier Reef physical oceanography cruises (SGBR Project 1989-1990)

A series of three oceanographic cruises were made to the southern Great Barrier Reef between 1989 and 1990. The cruise dates were:SGBR1: 23/8/1989 to 2/9/1989SGBR2: 15/10/1989 to 29/10/1989SGBR3: 19/2/1990 to 28/2/1990The instruments deployed during these cruises were:1. An array of tide gauges at Heron Island, Karamea Bank, Lady Elliot Island, Middle Island, North Reef, Perforated (Peak) Island Saumarez Reef and Gannett Cay.2. An array of current meters at Lady Elliot Island, North Reef, Saumarez Reef and Karamea Bank. 3. A weather station on Wistari Reef4. Drogues5. CTD and XBT profiles along transects and at moorings.6. Horizontal profiles
 The purpose of the study is to investigate mesoscale flow dynamics by observing the current, sea level and frontal structures of the region and to relate the changes observed to the physical forcings at the surface and horizontal boundaries.
 Over a period of 3 years cold water upwelling and entrainment features have been observed in AVHRR thermal imagery in the Capricorn channel during spring-time (September to December). Cool, saline water which exists on the narrow shelf south of the Capricorn channel apparently is upwelled or advected seaward just north of Heron Island and becomes entrained in the EAC. A mushroom jet-like feature has also been observed emerging from the coast between Cape Clinton and Bustard head. These features tend to be associated with relaxation or reversal of the prevailing SE trades and with weakening or reversal of the southward flow of the Eastern Australian Current (EAC).
