Hydrothermal springs

Hydrothermal springs that you can visit without a deep-sea submersible. When teaching about hydrothermal springs, I usually use a video a friend of mine took of hydrothermal vents on the mid-Atlantic ridge on the WHOI submersible Alvin. But being on Iceland now, there is much better material available which students can even go and experience […]

Interference of waves.

Movie on wave interference – two wave fields arriving perpendicular to each other, interacting and leaving. When talking about waves, it is often difficult to explain that wave heights of different components of a wave field can be added to each other to give a resulting wave field, but that each of those components continues […]

Internal waves in the atmosphere

A photo of internal waves in the atmosphere. Internal waves exist on the interface between fluids of different densities. In the ocean they are mostly observed through their surface imprint. In the tank, we could also observe them by looking in from the side, but this is hardly feasible in the ocean. But luckily vision […]

Ice in the ocean – my historical photos

mglessmer — Mon, 16 Sep 2013 04:38:40 +0000

Ice formation in the ocean – using my own photos to tell the story. Recently I talked about using my own photo to explain the generation of wind-generated waves to students. And then I realized that there is another set of photos that I have been using for teaching purposes for years that I could […]

A fetching title for a fetching photo post

Using a photo from one of my research cruises to explain the formation of wind waves. Wind waves are (surprise coming up!) waves generated by wind that blows over the ocean’s surface. The size of those waves depends on several factors: The strength of the wind, the length of time the wind has been blowing […]
