Marine Geophysics in 2020: Two Voyages on the R/V Tangaroa

Ingo Uncategorised , ,

The second half of 2020, luckily, was very busy for our Marine Geophysicists with two successful, major cruises.

CSEM for gas hydrates on the Hikurangi Margin, R/V Tangaroa TAN 2012, 1 – 13 Nov. 2020

R/V Tangaroa voyage TAN 2012 aimed at controlled-source electromagnetic (CSEM) survey of gas-hydrate bearing sediment on the southern Hikurangi Margin using Scripps’ system.  Gas hydrate, as an insulator, is known to increase sediment resistivity.  Beyond CSEM, we collected TOPAS sub-bottom profile, water-column echosounder, and multibeam data.

From our group, Ingo Pecher and Laurenz Boettger took part.  The voyage was led by Peter Kannberg at the Scripps Institution of Oceanography, with Karsten Kroeger (GNS Science) and Ingo Pecher as co-leaders.  It was funded by the Ministry of Business, Innovation, and Employment (MBIE; Tangaroa Reference Group), the US National Science Foundation and the MBIE Endeavour grant “Economic Opportunities and Environmental Implications of Energy Extraction from Gas Hydrates”.

 

Chatham Rise pockmarks, R/V Tangaroa TAN 2006, 26 June – 17 July 2020:

R/V Tangaroa voyage TAN 2006 aimed at investigating pockmarks on the Chatham Rise and their potential link to the release of geologic CO2.  We hypothesize that CO2 originating from the subducted Hikurangi Plateau is released episodically during glacial-stage maxima forming pockmarks.

Despite adverse weather, we acquired pseudo-3D seismic data in a 6×2 km2 block (densely spaced 2-D seismic data) and 300 km of 2-D seismic lines using NIWA’s high-resolution seismic system.  Seismic data quality is excellent (see image).  We also acquired almost 3000 km of TOPAS sub-bottom profiler lines and multibeam bathymetry.

Ingo Pecher, Michael Macnaughtan, Laurenz Boettger, and Declan Andrew took part from our group.  The voyage was led by Ingo Pecher and Jess Hillman (GNS Science) and funded by MBIE (Tangaroa Reference Group), the Marsden Fund grant “Geologic champagne: What controls sudden release of CO2 at glacial terminations on the Chatham Rise?” and a GNS Science Large Project Investment Fund.

Deadline 24 July 2020: ANZIC IODP Legacy Analytical Funding

Ingo Uncategorised

ANZIC IODP Legacy Analytical Funding (AILAF)

Members of the Australian and New Zealand International Ocean Discovery Program Consortium (ANZIC) have the opportunity to apply for grants of up to $20,000 (or $30,000 if leveraged) to support studies of legacy scientific ocean drilling (DSDP, ODP, IODP) material and/or data, through the ANZIC IODP Legacy Analytical Funding (AILAF) program. This successful program has supported many legacy grant projects centred on the analysis of previously collected DSDP/ODP/IODP samples and has facilitated the rapid production of high-quality publications, conference presentations and/or outreach activities.

Current Call:

In 2020, ANZIC will provide a pool of up to AUD$200K worth of funding (and a separate pool of NZD$50K for New Zealand applicants), to be distributed to appropriate projects that can be completed by 15th November 2021. Applications should be proposed that seek analytical fund support of up to $20K, whether these are for sample or data projects. Proposals focussed specifically on data and data product projects that can demonstrate additional leverage towards a project, can apply for up to $30K. In 2020, the AILAF program is being expanded to also include a call for projects that are specifically designed to utilise the wealth of data and data products that have been generated through 50+ years of ocean drilling. Projects with a clear scientific focus, but that require support to make use of these datasets and translate the data into knowledge, are being sought. We expect this will open the call to sections of the scientific community (i.e. data analysts/mathematicians/visual data scientists/ molecular/ genetic analysts) who may not traditionally work in or with the geosciences and therefore not normally apply for ANZIC support. Expected outputs are high-quality publications and/or products, adhering to the FAIR data principles (https:// www.ands.org.au/working-with-data/fairdata).

For further information, proposal templates, etc., please contact Ingo (i.pecher@auckland.ac.nz).

Call to Sail!

Special call for scientists with expertise in radiolarian micropaleontology, preferably with experience in the northwest Pacific region, to apply for Expedition 386. The deadline to apply for this special call is October 11, 2019 at 11:59 PM EDT.

IODP is now accepting applications for scientific participants on Expedition 386 Japan Trench Paleoseismology, aboard a Mission-Specific Platform (MSP) organised by the ECORD Science Operator (ESO) and jointly implemented with the Institute for Marine-Earth Exploration and Engineering (MarE3) within the Japan Agency for Marine-Earth Science and Technology (JAMSTEC). At this time, it is envisaged that the offshore phase of Exp. 386 will take place on the R/V Kaimei for up to 50 days in spring and/or summer of 2020 (Apr-Aug).

To learn more about the scientific objectives of this expedition please watch this informational webinar held on 20 June 2019 here. More detailed expedition information: http://www.ecord.org/expedition386/

ANZIC MASTERCLASS 2019, SYDNEY 2- 10 December, 2019.

ANZIC is pleased to announce its 2019 Masterclass in Sydney, hosted by University of Sydney (USYD) and Macquarie University (MQ), 2-10 December 2019.

DESIGN: This course will introduce students to the exciting world of marine geosciences through a combination of practical workshops, geological fieldwork and marine activities. Based around the Sydney Institute of Marine Science (SIMS) the course will cover the background of the International Ocean Discovery Program (IODP) and marine geoscience – delivered by marine geoscientists from Macquarie University, the University of Sydney, and CSIRO.

OPEN TO: The Masterclass is open to one excellent student from each Australian and New Zealand IODP member university who is completing 2nd or 3rd year. Students must provide a short written statement to their University leadership (up to 250 words) stating why they would like to participate in the Masterclass. Selection will be based on academic achievement and perceived benefit to a student’s course of study.
