Hi,
Just before Christmas twenty sesmic data buoys were dispatched to the bottom of the Kish Basin. They have all surfaced recently(as designed) but due to stronger than expected \'currents\' and I assume the prevailing easterlies of the last couple of weeks they have dispersed more quickly than anticipated, so they have not all been retrieved at sea as planned.
I retrieved one over the last few days form the North Beach in Rush, there is a \'finders\' fee, so keep your eyes open !
They can be towed from a kayak, allow lots of time !
Details of how they work and some photos at http://www.geopro.com/instrumentation/o ... e-obs.html
