But let’s start from the beginning and talk ocean temperatures. Depending on where you live and surf, the temperature of the ocean can range a lot from tropical warm water temps (countries on the equator), to freezing cold water temps (think Arctic surfer with icicles in his beard). In...
Summer near‐surface seawater sampling in the Canadian Arctic revealed potential for significant errors (nearly 0.1 μmol·(m‐2 s‐1)) in CO2 fluxes calculated from measured air‐sea CO2 gradients. River runoff and sea ice melt strongly stratify these waters, often resulting in surface mixed ...
How in the world would you know which way to go unless you had a compass to tell you which way is "up"? Long before GPS satellites and other high-tech navigational aids, the compass gave humans an easy and inexpensive way to orient themselves. But what makes a compass work the way ...
