A series of videos to highlight the diversity of the IMOS data collection, its use and its impact.
Professor Chari Pattiaratchi of University of Western Australia and leader of IMOS Ocean gliders facility, talks about the Challenger glider mission. This mission to guide an underwater glider from Fremantle, Western Australia to Galle in Sri Lanka will be the longest glider mission ever undertaken.
IMOS Director, Tim Moltmann, explains how IMOS is a unique collaboration of Australia’s leading research organisations, deploying a network of advanced technologies to deliver data about Australia’s oceans.
IMOS undertakes systematic, sustained, and scientifically-robust observations of Australia’s vast and valuable ocean estate and converts these observations into data, time series, products and analyses that can be used and reused for broad societal benefit.
IMOS OceanCurrent uses data from a range of sources to create visual representations of water movement, sea surface temperature, ocean colour and sea surface height.
This information is made publicly available and has practical applications including commercial shipping, fishing, search and rescue efforts and recreational activities like boating and even ocean swimming.
OceanCurrent maps inform research into areas such as the interaction between currents, sea-level and climate and the movement of nutrients, sediment and species.
Marine data and information are the main products of IMOS. The Australian Ocean Data Network (AODN) provides an online portal for accessing the large and diverse collection of IMOS data and ocean data from other sources. Scientists, managers and the public can access desired data collections for free – and it’s as easy as 1-2-3.
The East Antarctic ice sheet and shelves, once thought to be stable, are showing signs of thinning (melting).
Using data from IMOS funded moorings off the Totten and Mertz glaciers, Dr Steve Rintoul presents evidence that warm water beneath the ice shelf is causing this ice loss.
Obtaining good time-series data on ocean variables near these East Antarctic glaciers will improve our understanding of processes and time frames of glacial melting.
The second video in the 'IMOS in MOcean' series examines carbon and heat transfer between ocean and atmosphere. CSIRO scientist, Tom Trull, explains how these processes in the Southern Ocean play a key role in global climate change and how IMOS measures these variables.
In the first episode of IMOS in mOcean, Dr Michelle Heupel from the Australian Institute of Marine Science (AIMS) talks about her research tracking sharks. Michelle describes the surprising results that demonstrated the long-range migration of bull sharks from Sydney Harbour to the Great Barrier Reef.
Knowledge of marine animal movements can inform decisions about marine resource management, for example the merits of marine protected areas.
