Temperature - Salinity distributions / CTD data at sampling stations on a transect between Red Point and Creswell, Jervis Bay

This dataset is a component of the 'Jervis Bay Baseline Studies' project conducted by the Department of Defence, CSIRO and the Australian Defence Force Academy. 
Approximately once per month between 1988-1991, temperature-salinity surveys were conducted on various transects within Jervis Bay and out across the continental shelf. This record describes CTD data from a N-S transect, running from Red Point in the north, to Creswell in the south. Measurements were made using a Neil Brown 'Smart' CTD. On the day of sampling 9 stations were chosen on the transect, with the CTD recorder measuring salinity, temperature and sigma-T through the water column.
Two resources are provided: 1) An excel document providing details of sampling locations and the raw CTD data collected, and 2) A map showing the location of each sampling station.
This is one of nine child records that relate to the parent, 13391430-2ae8-11dd-a735-00188b4c0af8. A pdf outlining the structure and hierarchy of all metadata records relating to this project is available to download through this record. Also available is a pdf of a published working paper documenting this experiment and the results.

Phytoplankton concentration measurements in Sydney Harbour - 21st October 2004

A study of the response of phytoplankton to rainfall in Sydney Harbour on 21st October 2004 is reported here. 
Sydney Harbour is an important port and recreational region for the city of Sydney. Phytoplankton can be used as one of the indexes of water quality. The concentration of phytoplankton is influenced by the nutrients in the water and the amount of nutrients is thought to alter according to the urban and industrial wastes that drain from the city of Sydney.  
The amount of phytoplankton before and after rainfall at Pyrmont in Sydney Harbour was observed. The concentration of chlorophyll after a period of rainfall from the 15th October to the 4th of November 2004, as measured from the surface to 7m deep, was almost 5 times as much as that as before the rain event. The maximum chlorophyll concentration observed by fluorometer was 27 [ug/litre].

Datasets relating to samples collected from the Lagoon physiographic zone on Wistari Reef

Wistari Reef is a lagoonal platform reef, situated on the Tropic of Capricorn, within the Capricorn and Bunker region of the southern Great Barrier Reef. Surface samples were taken from the lagoon area to determine the mean grainsize and the sorting coefficient and also the proportion of aragonite to calcite within the samples. Within the lagoon area the average mean grainsize is ~1.25phi, with an average sorting coefficient of 1.04phi. Individual samples exhibited much variation in grainsize and sorting. The 'lagoon' physiographic zone needs to be sub-divided into 'deep-lagoon' samples (eg S16) and 'patch-reef dominated' samples (eg S11). The sediments of the 'deep-lagoon' are poorly sorted medium to fine sands, with little contribution from in situ patch reef growth. The 'patch-reef dominated' sediment is a poorly sorted medium sand, and contains a high proportion of coarser grains derived from patch reefs within the lagoon. There was a higher proportion of Aragonite in the samples compared to calcite.

Future Reef MAP - March 2013 (Southbound)

Data were collected as part of the FutureReef MAP project, a three-year project designed to monitor ocean chemistry along the entire length of the Great Barrier Reef. The Future Reef MAP project is funded by Rio Tinto Alcan and administered by the Great Barrier Reef Foundation, with an equal co-investment by CSIRO. The project is the first large-scale CO2 observing system established on the Great Barrier Reef using the Rio Tinto ship, RTM Wakmatha. The research is targeted at providing information on the CO2 uptake and the controls on ocean acidification change in the region. It is providing foundation data needed to assess the vulnerability of the GBR reefs to ocean acidification. This dataset contains quality controlled underway measurements of the fugacity of CO2, atmospheric pressure, and sea surface temperature and salinity. The data management and distribution of these data were supported by the CSIRO Carbon Collaboration Cluster and the Australian Coastal Ecosystem Facility.

Totten Glacier ocean & sediment DNA (IN2017_V01)

This record presents genetic data underlying the paper 'From the Surface Ocean to the Seafloor: Linking Modern and Paleo-genetics at the Sabrina Coast, East Antarctica (IN2017_V01)' by Armbrecht et al. In this study, we provide the first taxonomic overview of the modern and ancient marine bacterial and eukaryotic communities of the Totten Glacier region, East Antarctica, using a combination of 16S and 18S rRNA amplicon sequencing (modern DNA) and shotgun metagenomic (sedimentary ancient DNA, sedaDNA) analyses, respectively. We explore environmental and geochemical variables that drive these biodiversity patterns. Our data show considerable differences between eukaryote and bacterial signals detected via DNA analyses in the water column vs. the sediments. Organisms that are well represented in deeper waters appear are to have a higher likelihood of becoming preserved in the sediments. The study provides the first assessment of DNA transfer from ocean waters to sediments, while also providing a broad overview of the biological communities occurring in the climatically important Totten Glacier region.

Fast Repetition Rate Fluorometry (FRRF) data collected on the RV L'Astrolabe from 18/02/2007 to 23/02/2007 (Hobart - Dumont d'Urville)

These data were collected on the RV L'Astrolabe (platform code: FHZI) from 18/02/2007 to 23/02/2007 on a trip from Hobar 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).

Water current readings from the North East mooring in Jervis Bay (off Green Point): 11/07/90 - 29/08/90

A current meter mooring was deployed in the NE section of Jervis Bay (35.0305S, 150.756E) between 11/07/90 and 29/08/90. This mooring held two S4 Interocean current meters at depths of 11.5m and 5.5m. 
Each of these current meters provided two datasets. In the first, the meter integrates the signals over 2 minutes every 10 minutes, providing 10 min sample readings. The second decimated the samples using a running mean to provide hourly intervals. 
The data provided includes the eastern and northern tidal components, speed, direction and temperature. The datasets providing the 10 minute sample values also give depth and salinity readings. 
Users should be aware that there appears to be some data corruption in the later stages of the datasets collected from 11.5m. In addition to this corruption, the decimated hourly dataset relating to the meter at 5.5m is unfortunately missing

Habitat Map for Lizard Island reef, Australia derived from a photo-transect survey field data collected in December 2011 and September/October 2012

An object based image analysis approach (OBIA) was used to create a habitat map of Lizard Island reef, Queensland.
Georeferenced dive and snorkel photo-transect surveys were conducted at different locations surrounding Lizard Island. Dominant benthic or substrate cover type was assigned to each photo by placing 24 points random over each image. Each point was then assigned a dominant cover type using a benthic cover type classification scheme containing nine first-level categories - seagrass high (&gt;=70%), seagrass moderate (40-70%), seagrass low (&lt;= 30%), coral, reef matrix, algae, rubble, rock and sand.
The OBIA class assignment followed a hierarchical assignment based on membership rules with levels for "reef", "geomorphic zone" and "benthic community" (above).
This record contains a snapshot of the data taken for use in Seamap Australia (a national benthic habitat map; https://seamapaustralia.org). View the original record at: https://doi.pangaea.de/10.1594/PANGAEA.864209

Survey data collected from Core E53-10, located on the edge of the South Tasman rise

Most globally linked climatic records dealing with continuous longterm change are derived from the ocean sea-floors where sedimentation of microplankton is accumulated on a time scale of several centimetres per 1000 years. Variations in microfossil records over time are used as proxies for changes in the oceans.
Core E53-10 was sampled in April 1993 while visiting the Antarctic Research Facility at Florida State University. Preliminary diatom analysis of prepared slides indicate that the core contains REWORKED species. The presence of Actinocyclus ingens, Hemidiscus karstenii, Stephanopyxis spp, Denticulopsis spp and other non-Holocene/late Quaternary species were encountered throughout all the samples examined in the first two meters of the core. Upon this observation, the core was abandoned for further study. Independent results of the zinc-silica ratio analysis performed on sub-samples also indicates an anomalous response, which is interpreted to be resultant of the reworked material incorporated in the core.
This region appears to be under a sedimentary reworked environment imposed by the drop off to the north of the South Tasman Rise.

AIMS Marine Bioresources Library Database

The AIMS Bioresources Library contained almost 20,000 entities, including extracts from over 7,600 samples of marine micro-organisms, frozen material and over 9,000 cryopreserved marine-derived micro-organisms. Biodiscovery is the sourcing of native biological material including plants, animals, fungi and microorganisms to identify bioactive compounds genes, enzymes and other proteins that may be used for commercial purposes such as pharmaceuticals and insecticides. AIMS has been involved in biodiscovery for 15 years and has explored Australia&#39;s mega-marine biodiversity for attributes with commercial application. The cornerstone of AIMS&#39; biodiscovery effort is its substantial marine Bioresources Library. This collection has been sourced from over 1,500 sites across Australia.
An Oracle database for the AIMS Bioresources Library was developed to contain information of taxonomy, housekeeping (location and nature of samples including taxonomic vouchers, extracts, fractions, pure compounds, frozen cultures), and biodiscovery research history (e.g. screening and structure elucidation results, dispatches to various external parties, etc).
The database includes images most organisms and records the results of an array of bioassay tests which have varied over time with different programs and collaborators, and include anti-cancer, AIDS, anti-biotic and enzyme inhibition assays.
The taxonomic data is available for release as long as the master sample numbers are not used as unique sample identifiers, e.g. OBIS. Requests for selected data release will be considered on a case by case basis as some information is commercial in confidence and may be subject to contract conditions.
The database aimed to:
-collate taxonomic and biogeographic details
-link taxonomy and biogeography with bioactivity, and facilitate data mining
-track the use of samples in their various forms
-ensure compliance with contracts and access/benefit sharing agreements and permits
-generate reports to regulatory authorities and jurisdictions of origin, on the use of material
A subset of the data has been provided to the Ocean Biogeographic Information System (OBIS, http://iobis.org/explore/#/dataset/123l).

IMOS - Southern Ocean Time Series (SOTS) - Annual Reports

The Southern Ocean Time Series (SOTS) Observatory is a Sub-Facility of the Australian Integrated Marine Observing System (IMOS), funded by the National Collaborative Research Infrastructure Strategy (NCRIS).  It is operated under collaborative arrangements by the CSIRO Oceans and Atmosphere, Bureau of Meteorology, and University of Tasmania (via the Antarctic Climate and Ecosystems Cooperative Research Centre).  The primary focus is sustained observing of ocean properties and processes important to climate, carbon cycling, and ocean productivity. 
SOTS consists of deep ocean moorings deployed in Subantarctic waters southwest of Tasmania, equipped with autonomous sensors and sample collectors.  SOTS moorings are serviced annually - the existing moorings are recovered and new moorings are deployed.  Some sensor data is transmitted from the moorings via satellite in near real time.  Other sensor data and samples are recovered during the annual service visit.
For each year, three reports are issued:
Report 1. Overview of mooring voyages, dates, locations, designs, instruments 
Report 2. Samples from moored and shipboard sample collections 
Report 3. Sensors mounted on the moorings moored and shipboard
These reports focus on metadata, i.e. descriptions of the moorings, sensors, samplers, and their deployment, recovery, processing, analysis and curation.  Pointers are provided to supporting information from voyage reports and to on-line sources of the data. Shipboard sensor and sample measurements made during the service visits are also described. 
Report 1. Overview - describes the deployment and recovery of the moorings. It provides their locations, drawings of their designs, and lists of each instrument deployed and the variables measured.  It also summarizes ancillary measurements and sample collections made during the deployment and recovery voyages. 
Report 2. Samples - describes 3 main types of samples and associated composition measurements:
1.  Sediment trap samples collected by the Subantarctic Zone (SAZ) mooring.
2.  Water samples collected by the RAS water sampler deployed on either the Pulse or Southern Ocean Flux Station (SOFS) mooring, and collected by the TM sampler deployed on the SOFS mooring.
3.  Samples collected with other devices during the SOTS service voyages, e.g. from CTD Niskin bottles, in-situ pumps, continuous plankton recorders, and nets.
Note that not all these sample types were collected in any given year.
Report 3.

OZCAM: Online Zoological Collection of Australian Museums

OZCAM stands for the Online Zoological Collections of Australian Museums. The site provides a "proof of concept" that it is possible to provide access to datasets around Australia via a single portal. Currently, queries can be made on five groups of animals: mammals, reptiles and amphibians, fishes, dung beetles and molluscs. An extensive query screen allows the user to query by taxon name, by place, by time or by a combination of these. The user can also nominate which museums are to be queried. Data returned from sites around Australia can be displayed either as dots on a map or as a list. From either of these displays it is possible to mine the data further and view the raw dataset for any single specimen.

Loggerhead turtle tagging program: Turtle Bay, Dirk Hartog Is - Jan 2007

To determine the long-term population levels and trends of the loggerhead turtle population nesting at Turtle Bay, Dirk Hartog Is.
Volunteers were used to assist with observations of turtle nesting and egg laying, and assist with tagging of loggerhead turtles each night for six nights.
The sandy beaches of Turtle Bay, at the northern end of Dirk Hartog Island, are among the few key WA nesting sites for the loggerhead turtle (Caretta caretta). (The nesting sites are very close to Cape Inscription). The species is considered the most endangered turtle that nests in the Australian region and is declared threatened under the WA Wildlife Conservation Act.

Determining the grainsize of sediment with increasing depth in core GC10, located in the Capricorn Channel

A gravity core (GC10) was collected from a depth of 335 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). Samples were separated into different size fractions to determine the % of each grainsize at each sample depth. Although not overly accurate, the information is correlated with analyses of other parameters to impart clues to the environmental changes within the core. This assembly of information suggests that the core reaches the Last Glacial Maximum (LGM) at ~130cm depth. The smallest size fraction (&lt;100µm) dominates at all depths, with the shallowest sample (5cm) exhibiting 93% of material within this size range.
