The play of light on water
can reveal overlooked details and nuances to photographers and artists
on Earth. The same thing can happen when looking from space.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra
satellite looked down on the Canary Islands on June 15, 2013. The
Atlantic Ocean has a silvery or milky color in much of the image, the
result of sunglint. Sunlight is being reflected off of the ocean surface
directly back at the satellite imager, revealing details about the
water surface or circulation that are otherwise invisible.
In the image above, wavy, windsock-like tails stretch to the
southwest from each of the islands. The patterns are likely the result
of winds roughening or smoothing the water surface in different places.
Prevailing winds in the area come from the northeast, and the rocky,
volcanic islands create a sort of wind shadow—blocking, slowing, and
redirecting the air flow. That wind, or lack of it, piles up waves and
choppy water in some places and calms the surface in others, changing
how light is reflected. Ocean currents, oil or pollution slicks, and internal waves can also alter surface patterns, though none are necessarily visible in this image.
According to sailors’ guides to the area, winds on the leeward side
of the Canary Islands often blow in the opposite direction of the
prevailing winds. The play of land and wind can also create a funnel
effect, speeding up air flow around the coasts. The swirling nature of
the leeward wind field is shown in a long, helical trail of clouds
stretching southwest from Tenerife (the second island from the right).
