Superlatives of the sea
This past Friday I had a particularly curious and enthusiastic fifth block Oceanography class. All of their questions were marine science related so I broke out some notecards and asked them to write all of their burning inquiries down. I wanted to tackle them thoughtfully … here I am!

Why does it feel like the ocean is pulling on you when your just standing in the water?
The “pull” of the water that you feel as you stand in the shallows near the shoreline is just moving water rubbing against your skin. So, why is the water moving out to sea near the beach? Several different forces push – or pull – an excess of water up onto the beach, and then […]

The flight of swallows
