Berkeley Lab researchers successfully use distributed acoustic sensing for seismic monitoring

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown for the first time that dark fiber – the vast network of unused fiber-optic cables installed throughout the country and the world – can be used as sensors for detecting earthquakes, the presence of groundwater, changes in permafrost conditions, and a variety of other subsurface activity.

Newly Discovered Juvenile Whale Shark Aggregation in Red Sea

Researchers Get Rare Glimpse into the Lives of Ocean’s Gentle Giants

Whale sharks (Rhincodon typus)—which grow more than 30 feet long—are the largest fish in the world’s ocean, but little is known about their movements on a daily basis or over years. A newly discovered juvenile whale shark aggregation off Saudi Arabia is giving researchers a rare glimpse into the lives of these gentle giants. (more…)
