East Indian Ocean

More than 90% of the energy trapped on Earth by increasingly abundant greenhouse gases is absorbed by the ocean. Monitoring the resulting ocean warming remains a challenging sampling problem. To complement existing point measurements, we introduce a method that infers basin-scale deep-ocean temperature changes from the travel times of sound waves that are generated by repeating earthquakes. A first implementation of this seismic ocean thermometry constrains temperature anomalies averaged across a 3000-kilometer-long section in the equatorial East Indian Ocean with a standard error of 0.0060 kelvin. Between 2005 and 2016, we find temperature fluctuations on time scales of 12 months, 6 months, and ~10 days, and we infer a decadal warming trend that substantially exceeds previous estimates.

Oceanids is a 4-year programme for the technological development of innovative Maritime Autonomous System (MAS) platforms and associated sensors that will include next generation robotic AUVs, sensors and networks to undertake ambitious, long-range, long-endurance deployments in extreme and hazardous environments, such as the deep ocean or under-ice environments. This paper describes the design of two new types of robotic AUVs, the Autosub 2000 Under-Ice and the Autosub Long Range 1500 vehicles that are being developed under the programme. Two key components of the AUVs are described, the autonomy framework and the navigational system, which relies on a newly developed terrain-aided navigation (TAN) system. At-sea results of the TAN are also reported as obtained during long duration operational deployments done in 2017.
