Around the world, extreme wave heights and ocean winds are increasing. The greatest increase is happening in the Southern Ocean, according to recent research from the University of Melbourne , and Dr. Ian Young corresponded with EM about what inspired the work.
“Our main interest is ocean waves, and we are interested in wind because it generates waves,” explains Dr. Young. “Ocean waves are important for the design of coastal and offshore structures, the erosion of beaches and coastal flooding, and the safety of shipping.”
Waves also have a role in determining how much heat, energy and gas can be trapped in the ocean.
“The major reason why changes in wave height may be important is because of sea level rise,” details Dr. Young.Read More
All year long the US Geological Survey (USGS) in North Dakota and South Dakota monitors water levels, but during times of flooding, all eyes are on the team. EM spoke to USGS data chief Chris Laveau about the monitoring efforts.
“The US Geological Survey in North Dakota and South Dakota is one entity, so we monitor the flooding in both states,” explains Mr. Laveau. “The role is to provide continuous information on water level, we call that gauge height or stage, and we also provide continuous information at a lot of locations on stream flow, typically called discharge. We do that year round but, obviously, during a flood event it garners more attention.Read More
Say the word “tsunami” and images of tremendous waves engulfing homes or masses of debris might come to mind. Those tsunamis that are triggered by massive landslides and earthquakes are in fact at that scale.
But weather can trigger more localized “meteotsunamis” as well, and new research shows just how common these are along the East Coast of the United States. National Oceanic and Atmospheric Administration (NOAA) physical oceanographer Gregory Dusek of the National Ocean Service in Silver Spring, Maryland, spoke with us about the work.
“The public noticed the 2013 tsunami event, we did a report summarizing that event in our office, and we started wondering how frequently these actually occur,” explains Dr. Dusek.Read More
