Behemoth waves are more than just folklore. Learn the science behind these deadly swells.
Read MoreHow do polynyas help feed emperor penguins?
When female emperor penguins—and later, males—return to the ocean to feed, they need a spot that gives them easy access to both the water and the ice. And, they also need places that are teeming with fish and other types of prey. Learn how polynyas provide a place where penguins can feast and build their energy reserves after breeding.
Read MoreOcean acidification is no big deal, right?
Some people argue that ocean acidification isn’t an issue of concern. After all, they say, the ocean isn’t actually acidic. There is some truth to that. On the pH scale,…

Read MoreSea level rises when land sinks
People around the world are worried about rising sea levels. Much of this increase comes from melting polar ice and ocean waters that expand as they warm. But along many coastlines, sea level rises much more than we might expect simply from changes in the ocean.
Read MoreWhy is glacier ice blue?
When sunlight shines on a field of snow, it reflects a bright-even blinding-white. But if you get a good look at the leading edge of a glacier, you’ll find that the ice inside is a brilliant blue.
Read MoreIs glacier ice actually rock?
In places where it gets cold and snowy in winter, many meters of snow can fall. In some the following winter, adding a new layer to what was already there. Over hundreds to thousands of years, this process creates big sheets of ice called glaciers.
Read MoreHow do corals form colonies?
If you stare at just one spot on a coral reef, your eyes could be seeing more than 1,000 animals per square foot. That’s because the thing that makes up most of these marine ecosystems are tiny living animals called coral polyps, which exist on the surface of reef formations.
Read MoreWhat makes the ocean salty?
The water flowing into the ocean comes from freshwater streams and rivers. These bodies of water do contain salt. It dissolves from rocks on land. That’s because rain is slightly acidic.
Read MoreHow do glaciers affect sea level rise?
Sea levels have risen and fallen throughout geologic history due to a myriad of natural processes, most notably the forming and melting of glaciers.
Read MoreHow does the ocean affect storms?
Under the right conditions, some of those storms can grow into large tropical storms. Or even monstrous hurricanes.
Read MoreAre corals plants, animals, or rocks?
The base of a coral reef is coral, but what is coral? If you look at a piece of coral that washed up on shore, it’s solid and tough with rough edges and little pits.

Read MoreWhy do corals bleach?
Corals have a symbiotic relationship with algae. The algae gives corals their color and provides them with food. In return, corals provide the algae with a place to live.

Bioluminescent blue-green “combs jellies” light up coastal shores at night, as well as the depths of the twilight zone, where a number of species have yet to be formally described.
Read MoreCreature Feature: Helmet Jellyfish
Due to their photo-sensitive red pigment, helmet jellies avoid sunlight like the plague, preferring the frigid depths of the twilight zone to the sun’s damaging rays.
Read MoreCreature Feature: Penguins
We might chuckle at the sight of penguins waddling over ice and belly-flopping into iceberg-studded waters, but these flightless birds would put Olympic swimmers to shame.

These enormous, blubbery marine mammals awkwardly belly-flop around on land, but are elegantly adapted for life in the twilight zone—where they spend 90% of their at-sea time.
