Is there a known correction for the striped pattern in Landsat 8 TIRS data?

Landsat provides beautiful data of ocean SST at 100 m resolution ... still there is an annoying stripe pattern in the images in the channel 10 (thermal infrared). Does any one has a correction for...

How to model sea ice creep effects on ocean wave dissipation?

I'm working on modelling the propagation and dissipation of waves in both the marginal ice zone and also in the ice pack. My understanding is that in the ice pack we may get both scattering (from...

What is the appropriate seismic attenuation (Q) for surface Rayleigh waves for periods from 10 to 300 s?

I'm trying to model propagation of these waves from oceanic sources. Webb (Nature 2007) suggests a low Q for periods between 20 and 40 s, or something like this. Is there any new knowledge on this...

What is the measured or expected effect of the ocean floor in wave-generated acoustic noise at very low frequencies?

I have been working for the last 3 years on noise generated by waves in the ocean. Firstly I was looking at seismic noise (measured by seismometers on land) but a recent paper by Duennebier et al....

Looking for a database of shoreface slopes...regional or global.

I've played with proxies from bathymetry at large scales or lidar data where available, but this is not very satisfactory. My goal is to compute wave reflection from shorelines (see Ardhuin &...
