All at sea

Check out the OSCAR Blog for all the latest updates on the oceanography data currently being collected by the science team onboard the James Cook research ship.

Synthetic tests

The focus in Durham over the last few weeks has been to check the configuration of the seismic experiment. Synthetic travel time data were produced by ray-tracing a 2D model of the oceanic crust. The data also provide a reference for arrival identification once the real data have been collected.

The next step is to produce synthetic seismic records using an approximation for the source wavelet, and to consider different ways of modelling energy propagation through the irregular structure of the extrusive basalts in crustal layer 2A.

OSCAR start-up meeting

A start-up meeting to review all aspects of the OSCAR project was held on 3 September 2014 at the National Oceanography Centre, Southampton. This was the first assembly of the whole project team since the start of the project, and included:

– introductions to PIs and research groups,
– an overview of the background and history of the project,
– a review of the hypotheses and questions driving the scientific objectives, and
– an outline of the expedition plans for oceanographic and seismic data acquisition.
