AMOS ICTMO IMOS Data workshop 2019

How to access and use IMOS data for your Research

Workshop Monday June 10th,1430 – 1730 at the Charles Darwin University Waterfront Campus

IMOS is looking forward to hosting this workshop in Darwin on the fringe of the 2019 AMOS-ICTMO Conference.

Since 2006, IMOS has been routinely operating a wide range of observing equipment throughout Australia’s coastal and open oceans, making all of its data accessible to the marine and climate science community, other stakeholders and users, and international collaborators. This workshop is to assist the scientific community to discover, access, download, use and understand the potential of the data.

Presentations will be made by key leaders and responsible for the collection and dissemination of the data and science users with examples of how they have used the data sets to further their research. Hands on guided tutorials will be show how the AODN portal can be used and a summary of tools that are available to analyse the data. Short abstracts can be found further down this document.

Preparation

WiFi                 Bring your own device

Eduroam is available at CDU and is the preferred method to access to the internet.  Anyone using it will need to set it up at their University/organisation, test it works, then they will be able to log in at CDU with their setup login and password. https://www.eduroam.org/

For general visitor/attendee use, there will be CDU public wifi as well. The access details will be supplied on the day.

Data Portal Your main access to marine and climate data is through the AODN Portal.

Data Tools

http://imos.org.au/data/data/imosdatatools/ from here you can download Gliderscope and other tools.

IMOS OceanCurrent                              http://oceancurrent.imos.org.au/

Ocean Data View 
Ocean Data View (ODV) is a program designed for the interactive graphical display of oceanographic data. The software is freely available for Windows, Mac OS X, Linux, and UNIX systems. To download ODV you must register for free on the website http://odv.awi.de (go to the ‘Software’ tab). 

Download the Ocean Data View Manual v1.3.
The Manual was prepared by the Coastal and Regional Oceanography Lab at UNSW.

Python example scripts will alsobe provided and will conform to the requirements of the software carpentry course that will be held in the morning.

Abstracts

Introduction to the AODN Data Portal

Clothilde Langlais & Guillaume Galibert, Australian Ocean Data Network, Hobart, Tas

email:guillaume.galibert(at)utas.edu.au

The Australian Ocean Data Network (AODN) Portal provides access to all available Australian marine and climate science data including Integrated Marine Observing System (IMOS) data. These marine data collections are made freely available to the public. Data covers a wide range of parameters in different ocean environments collected from ocean-going ships, autonomous vehicles, moorings and other platforms. The scope of observations, geographically spanning ocean to coast, and across disciplines (physical, biogeochemical, biological), provides a challenge to deliver an intuitive easy-to-use robust information infrastructure enabling users to efficiently obtain the data they need. This presentation will be a live demonstration highlighting the main features and services the AODN Portal can offer in order to discover, visualize and access datasets. An afternoon tutorial will follow.


Observational data from across our tropical northern seas

Craig Steinberg, Australian Institute of Marine Science, Townsville, QLD

email: c.steinberg(at)aims.gov.au

AIMS operates a number of IMOS platforms across the tropical north of Australia. There a mooring arrays on the northwest shelf and along the Great Barrier Reef, National Reference Stations in Darwin and at the Yongala wreck near Townsville, a reef based sensor network and underway shipborne observations on two Research Vessels.  Beyond that AIMS has also operated reef based weather stations for over 30 years and manages a temperature logger programme in the region.  This presentation will show how you can access descriptions of all the mooring deployments, and near real time observational pages from a variety of sources.


Tools for exploring and using Ocean Glider Data

Yasha Hetzel, University of WA, Perth, WA &

Michael Hemming, University of New South Wales, Sydney, NSW

email:  Yasha.hetzel(at)uwa.com.au  m.hemming(at)unsw.edu.au

Software introduced includes Gliderscope, an elegant visualisation and analysis software developed specifically for ocean glider data and the near real time portals for current glider missions. Python & ODV will also reveal how to visualise the data. Using these tools, the workshop exercises will familiarise users with the types of data collected by ocean gliders, the ways data can be analysed and interpreted, as well as help them explore key principles of physical and biological oceanography.


Which SST Product Should I Use?

Helen Beggs, Bureau of Meteorology, Docklands, Vic

email: helen.beggs(at)bom.gov.au

There are a large number and range of remotely sensed sea surface temperature (SST) products available from the Integrated Marine Observing System (IMOS) that cover the Australian region at varying ocean depths, spatial and temporal resolutions (http://imos.org.au/sstproducts.html).  This presentation will guide users through selecting the most appropriate IMOS satellite SST product for their application, and how to benefit from the additional attributes in the Group for High Resolution SST (GHRSST) format files, such as quality level and Sensor Specific Error Statistics.  Some examples will be briefly shown of applications that use IMOS GHRSST products, and how one might find and extract the appropriate level of SST data for an application.


Monitoring Australian Seas with IMOS OceanCurrent

Craig Steinberg, AIMS, Townsville, QLD & Madeleine Cahill, CSIRO, Hobart, TAS

email: madeleine.cahill(at)csiro.au

OceanCurrent brings together the latest ocean observations from around Australia to provide context for marine studies and help you find IMOS data to support your work.

The satellite observations include sea surface temperature (SST), ocean colour (as a proxy for Chlorophyll), sea level anomaly and geostrophic surface currents. Different types of sea surface temperature are provided at a range of scales to cater for different requirements:

  • snapshots that give instantaneous images,
  • 4-hour composites,
  • 6-day SST composites with percentiles,
  • monthly SST and
  • SSTAARS climatology.

IMOS in-water data, including glider profiles, current meter data, Argo profiles, SealCTDs, HF radar velocities and research vessel underway data are plotted on all images and also in more much more detail on additional pages. OceanCurrent have begun making images clickable to make the IMOS data easier to view and to find on the AODN. In this workshop we’ll demonstrate how the website can work for you and would appreciate any feedback users may have.


Visualising IMOS data with python and ODV

Thanks to IMOS and the AODN portal, accessing vast numbers of high quality oceanographic datasets is now easier than ever. The second step to advance your research project is to visualize and analyse relevant IMOS data. While NetCDF format is very powerful and size-efficient for large datasets (gridded in time, latitude, longitude and depth), it can be hard to manipulate for those of us without strong programming skills (Matlab, R, Python, ets…). As an alternative for visualization, we will present how to use a freely available software, Ocean Data View (ODV, https://odv.awi.de), designed for the interactive graphical display of oceanographic data. We will show examples of how to plot a range of IMOS datasets from different observation platforms including: coastal moorings, HF radars, ARGO floats, ocean gliders, satellite sea surface temperature, ocean colour, and altimetry. Different types of graphs can be produced, includes: time series, depth profiles, hovmuller plots and maps. ODV also enables you to estimate derived variables such as potential density, Brunt-Vaisala frequency etc… and basic statistics. No more excuses not to do great science!
