Availability of mean squared slope or wave spectra data for the sea surface

The mean squared slope is a property of the sea surface that is often sensed by microwave radars [1] [2]. While spatial data for sea surface salinity, sea surface height, and significant wave height ...

Are extratropical cyclones the same as baroclinic waves?

Are extratropical cyclones the same as baroclinic waves? I'm aware of the fact that extratropical cyclones form in 'baroclinic zones' and that they start of as waves. But are these what are referred ...

How does multiple layer seismic reflection work? How do we distinguish arrivals from different layers and their velocities?

Whenever we are investigating multiple layer interfaces in a seismic reflection survey the root-mean-squared velocity is often employed to deduce travel time to a certain n-th layer and also to deduce ...

Where can I find wave scatter tables (joint probability Hs vs T) for certain coastal regions?

I am struggling to find a database or free source of joint probability of significant wave height and period, i.e. wave scatter tables. Data for buoys are useful, however not available for regions ...
