Seafloor environments of the eastern Timor Sea, Northern Australia: Sediment oxygen demand of seabed sediments.
No full textMaintenance and Update Frequency: asNeededStatement: Bulk sub-samples (6.5 ml) of surface sediment (0-2 cm) were incubated in BOD bottles for ~24 hrs in the dark at sea surface temperatures. Dissolved oxygen concentrations (and saturation values) were measured at the start and finish of each incubation. Results were expressed on a per g dwt basis utilising a separate sample to measure the water percentage. Analyses were corrected for blanks (filtered seawater).
The accuracies of the O2 measurements were +/- 1 mg/L. The accuracy of the scale used to measure wet/dry weights was better than 1%.The Timor Sea and its tropical marine environment support significant and growing economic activity including oil and gas exploration. To reduce uncertainty in decision making regarding the sustainable use and ongoing protection of these marine resources, environmental managers and resource users require sound scientific information on the composition and stability of seabed environments and their biological assemblages. Surveys SOL4934 and SOL5117 to the eastern Joseph Bonaparte Gulf were undertaken in August and September 2009 and July and August 2010 respectively, in collaboration with the Australian Institute of Marine Science, with research collaborations from the RAN Australian Hydrographic Office, the Geological Survey of Canada and the Museum and Art Gallery of the Northern Territory. The purpose of these surveys were to develop biophysical maps, and deliver data and information products pertaining to complex seabed environment of the Van Diemen Rise and identify potential geohazards and unique, sensitive environments that relate to offshore infrastructure. This dataset comprises sediment oxygen demand measurments made on the upper 2 cm of seabed sediments.<br/><br/><br/>Some relevant publications are listed below:<br/><br/>1.

Outer Darwin Harbour Shallow Water Sediment Survey 2016: Total sediment metabolism, carbonate, organic isotope and organic and inorganic element data on seabed sediments.
No full textMaintenance and Update Frequency: notPlannedStatement: Bottom sediments were collected using either a box core or a Shipek grab. The surface sediments (~0-2 cm) within each grab were spooned into falcon vials and the pore waters were removed by centrifugation. Pore waters were removed within 20 minutes of collection, and salinity, temperature and pH measurements were taken. The pore waters were then filtered (0.45 µm) into 3 ml gas-tight vials (that were pre-charged with 0.025 HgCl2). The procedure was repeated on pore waters from a second bulk sample that was incubated for ~24 hrs at sea surface temperatures. The residual sediment samples were then frozen for transport to the laboratories at Geoscience Australia (GA) where they were: (1) subsampled for specific surface area analysis; and (2) freeze-dried and ground in a tungsten carbide mill. The dried residue was divided into fractions for: (i) major and trace element analysis; (ii) bulk carbonate analyses; and (ii) total organic carbon and total nitrogen concentrations and isotopic ratios (after de-carbonation).
Dissolved inorganic carbon (DIC) concentrations were determined on pore water samples using a DIC analyser and infrared-based CO2 detector (Geoscience Australia). CO2 production rates were calculated by concentration differences over the incubation period, after correction for CaCO3 fluxes. The average %RSD of the precisions and accuracies of the dissolved inorganic carbon measurements were 0.2. The accuracy of the wet/dry weight used in the calculations were better than 1%.
Bulk carbonate was determined on dried ground sediment using the carbonate bomb method. The average precision (%RSD +/- s.d.) for 11 samples run in duplicate was 1.6 +/- 1.7%.
Specific surface areas were determined using a 5-point Brunauer-Emmett-Teller (BET) adsorption isotherm on a Quantachrome NOVA 2200e analyser, with nitrogen used as the adsorbate. The samples were first cleaned of organic matter by slow heating for 12 hours to 350oC.
Major and trace elements were determined in GA laboratories using X-Ray fluorescence (XRF; Phillips PW204 4kW sequential spectrometer) and ICP-MS (AGILENT 7500ce). Two Certified Reference Materials (CRMs) called CH-1 (Marine Sediment; Institute of Rock and Mineral Analysis, Beijing) and WG-1 (Woodstock Basalt; Australian National University, Canberra) were run in triplicate to calculate accuracy. Ten to twelve samples were also analysed in duplicate to measure precision. De-carbonated powders were sent to Environmental Isotopes Pty Ltd (Sydney) for isotopic analysis by mass spectrometry. Samples were back-corrected to account for the carbonate removal, using carbonate concentrations derived from the bomb method (this dataset). Quality control information is presented with the accompanying datasets.A benthic sediment sampling survey (GA0356) to the nearshore areas of outer Darwin Harbour was undertaken in the period from 03 July to 14 September 2016. Partners involved in the survey included Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Department of Environment and Natural Resources within the Northern Territory Government (NT DENR) (formerly the Department of Land and Resource Management (DLRM)). This survey forms part of a four year (2014-2018) science program aimed at improving knowledge about the marine environments in the regions around Darwin and Bynoe Harbour’s through the collection and collation of baseline data that will enable the creation of thematic habitat maps to underpin marine resource management decisions. This project is being led by the Northern Territory Government and is supported by the INPEX-led Ichthys LNG Project, in collaboration with - and co-investment from GA and AIMS. The program builds upon an NT Government project (2011-2011) which saw the collection of baseline data (multibeam echosounder data, sediment samples and video transects) from inner Darwin Harbour (Siwabessy et al. 2015). This dataset comprises Total sediment metabolism, %carbonate, organic isotope (C and N) and organic and inorganic element data from seabed sediments.<br/><br/>Radke, L., Smit, N., Li, J., Nicholas, T., Picard, K. 2017.

Accidental hypothermia in the household environment
No full textIn emergency medicine accidental hypothermia in non-traumatized patients is a rare situation. To emphasize the need for a precise preclinical temperature measurement, two cases of accidental hypothermia (28.2 degrees C and 29.3 degrees C core temperature) are presented which occurred under conditions that did not give a direct suspicion of hypothermia. In one case the immediate diagnosis lead to complete convalescence, the other patient died of multiple organ failure. The primary diagnosis, diagnostic methods and therapy as well as the primary treatment are discussed

Hemodynamic effects of spontaneous breathing in the post-operative period
No full textBackround: During mechanical ventilatory support, spontaneous breathing has been linked to improved hemodynamics. These findings may be explained by a decrease in intrathoracic pressure which may improve venous return to the heart. Such a mechanism should result in a dose-response relation between the amount of spontaneous breathing and an increase in the global end-diastolic volume (GEDV) and cardiac output (Q(t)). Methods: To test this hypothesis, 15 patients were studied after major elective surgery during weaning from mechanical ventilation using bilevel positive airway pressure (BIPAP). BIPAP allows unrestricted spontaneous breathing during every phase of the respiratory cycle. Thus, ventilatory support was modified by changing the mechanical respiratory rate only, whereas inspiratory airway pressure and PEEP were kept constant. GEDV and Q(t) were measured by transpulmonary thermodilution. Results: GEDV (P = 0.055), stroke volume (P = 0.027) and subsequently also Q(t) (P < 0.001) increased when spontaneous breathing increased. In contrast, no difference was observed for central venous pressure (P = 0.19). Conclusion: The beneficial hemodynamic effects of spontaneous breathing during mechanical ventilatory support can partially be explained by improved venous return to the heart which increases stroke volume and Q(t)
Seafloor environments of the northern Lord Howe Rise, Eastern Australia: Inorganic elements in seabed sediments.

Thanks to the crew of the RV Tangaroa for help with sample collection.Geoscience Australia marine reconnaissance survey TAN0713 to the Lord Howe Rise offshore eastern Australia was completed as part of the Federal Government's Offshore Energy Security Program between 7 October and 22 November 2007 using the New Zealand Government's research vessel Tangaroa. The survey was designed to sample key, deep-sea environments on the east Australian margin (a relatively poorly-studied shelf region in terms of sedimentology and benthic habitats) to better define the Capel and Faust basins, which are two major sedimentary basins beneath the Lord Howe Rise. Samples recovered on the survey contribute to a better understanding of the geology of the basins and assist with an appraisal of their petroleum potential. They also add to the inventory of baseline data on deep-sea sediments in Australia. The principal scientific objectives of the survey were to: (1) characterise the physical properties of the seabed associated with the Capel and Faust basins and Gifford Guyot; (2) investigate the geological history of the Capel and Faust basins from a geophysical and geological perspective; and (3) characterise the abiotic and biotic relationships on an offshore submerged plateau, a seamount, and locations where fluid escape features were evident. This dataset comprises inorganic element concentrations in seabed sediments.<br/><br/>Some relevant publications which pertain to these datasets include:<br/><br/>1.
