I gave this presentation at the University of New Hampshire's Center for Coastal and Ocean Mapping on April 18, 2014 describing the marine geophysical data life cycle and a variety of resources available to help investigators navigate the world of data management, as well as efforts focused on optimizing high-quality publicly available data.

The Global Multi-Resolution Topography (GMRT) synthesis is a multi-resolutional compilation of edited multibeam sonar data collected by scientists and institutions worldwide, merged into a single continuously updated compilation of global elevation data. The GMRT Synthesis, which began in 1992, brings together a variety of elevation sources, which are delivered as multi-resolutional images and grids of land and ocean elevations.
Slides from a presentation I gave as an Invited Guest Speaker at the 2016 University National Oceanographic Laboratory System (UNOLS) Fleet Improvement Committee (FIC) Meeting. Describes the overall activities of the Multibeam Advisory Committee (MAC. http://mac.unols.org) and results from recent Shipboard Acceptance Tests (SATs) of multibeam systems on the newest ships in the fleet.

Evolving NASA’s Data and Information Systems for Earth Scienceinside-BigData.com
In this deck from the HPC User Forum, Rahul Ramachandran from NASA presents: Evolving NASA’s Data and Information Systems for Earth Science.
"NASA’s Earth Science Division (ESD) missions help us to understand our planet’s interconnected systems, from a global scale down to minute processes. Working in concert with a satellite network of international partners, ESD can measure precipitation around the world, and it can employ its own constellation of small satellites to look into the eye of a hurricane. ESD technology can track dust storms across continents and mosquito habitats across cities. ESD delivers the technology, expertise and global observations that help us to map the myriad connections between our planet’s vital processes and the effects of ongoing natural and human-caused changes."

2nd Microscopy Congress: Public archiving of bio-imaging data - perspectives,...Ardan Patwardhan
The open and public access to structural data is of utmost importance for validation, development, testing and training. The Electron Microscopy Data Bank (EMDB) archive is the authoritative source for 3DEM data. In 2014 PDBe started EMPIAR – the electron microscopy pilot image archive to store raw image data related to EMDB structures. The challenge here has been in dealing with the storage and transfer of large datasets. EMPIAR is now fully functional with routine uploads and downloads in the Terabyte range. The success of EMPIAR has spurred interest in wider bio-imaging circles as a working example of image archiving and possibly even a prototype for a broader bio-imaging archive. I will describe EMPIAR and discuss the prospects for public archiving of bio-imaging data.
After emerging from the resources wilderness thanks to its world-class geology and industry-friendly government policies, South Australia is now a leader in Australian mining and hydrocarbon developments over the last decade.
In little more than a decade the State has gone from four operating mines to more than 20 and is rated Australia’s second most popular exploration destination.
With a comprehensive review of the Mining Act under way, the State’s attractiveness as a place for resources and energy investment is expected to be strengthened.
South Australia is now a leader in the exploration for next generation energy sources with companies such as Santos and BP leading the charge, while initiatives such as the Government’s Copper Strategy – designed to treble annual copper production to 1 mtpa – is set to establish the State as one of the world’s premier producers of the red metal.
In the energy space, uranium and nuclear energy is another area of keen interest, with the South Australian Government initiating a Royal Commission into Participation in the Nuclear Fuel Cycle in 2016.
The State has become synonymous with innovation, cutting-edge development and a remarkable rate of discovery. From uranium prospects, to geothermal energy and the buoyant hydrocarbons sector, South Australia is now a leader in the exploration for next generation energy sources.
With full support from the Department of State Development, the South Australian Resources and Energy Investment Conference will continue to showcase this burgeoning sector in 2017. From copper plays in the Gawler Craton, to iron ore and graphite developments on the Eyre Peninsula and the emergence of the State as a new hydrocarbon frontier, South Australia’s resources potential is at last being fully recognised.
The conference will feature the success stories and emerging players in the State from both minerals and oil and gas and will also tackle thorny industry issues such as infrastructure, corporate social responsibility and the future of the Woomera Prohibited Area.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
