The Marine Science Institute's monthly column, Science and the SeaTM, is an informative and entertaining article that explains many interesting features of the marine environment and the creatures that live there.  Science and the SeaTM articles appear monthly in one of Texas' most widely read fishing magazines, Texas Saltwater Fishing, the Port Aransas South Jetty newspaper, the newsletter of the Texas Chapter of the American Shore & Beach Preservation Association , and the Heartland Of America online newspaper. Our article archive is available also on our website.

Wind and gravity aren’t the only forces that move the ocean’s water — there’s also a conveyor belt at work.

The Great Ocean Conveyor works by thermohaline circulation — water movement caused by density differences. The oceans are layered in water masses that differ in temperature and salt content. Lower temperatures and higher salinity translate to greater density.

Bluefin tuna migrate thousands of miles, but exactly how they find their way through the vast blue is a mystery. One answer may lie with the tuna’s “third eye.”

Imagine a Komodo dragon the size of a large whale and you've got a rough picture of the mosasaur, one of the most fearsome predators in the oceans' history.

Top ocean predators of their time, mosasaurs were a group of carnivorous marine reptiles that lived during the Cretaceous period, roughly 90 million to 65 million years ago. Mosasaurs are thought to be related to present-day monitor lizards, and their fossilized remains have been found in many parts of the world.

With shells covered in algae and barnacles, decorator crabs are experts at blending in with their environments. But for one species of crab, it’s not just camouflage that keeps the hungry fish away.

When it comes to finding food and shelter on the vast open ocean, some petrels and related seabirds simply follow their noses.

Petrels are pelagic birds, which means they spend most of their time flying over open water, only venturing
onto land to raise young. Along with albatrosses and shearwaters, petrels come from an order of birds known
as “tubenoses” because of their prominent, tube-shaped nostrils. Birds in this order have some of the largest
olfactory bulbs − the portion of the brain involved in smelling − in the avian world.

With its streamlined shape, the blue shark is built for efficient swimming. But more impressive than its streamlined efficiency are the distances this shark covers in ocean-crossing migrations.

The blue shark is found throughout the world’s temperate and tropical oceans. As a pelagic species, it spends most of its time roaming open water.

In the ocean’s dim depths, it’s not easy being green; that’s why some plant-like organisms use different pigments to survive.

Think about locations of coral reefs around the world, and the last place you might list is Norway. But northern Norway is precisely where the largest known cold-water coral reef lies.

Cold-water corals are just that − coral species found in cold, deep water throughout the globe, on continental
shelves, ocean banks and seamounts. Living at depths of more than 3,000 feet in temperatures of 39 to 55 degrees Farenheit, cold-water corals form small patches or thickets as well as larger reef structures.

Comb through a heap of sargassum − that familiar brown seaweed that piles up on Atlantic and Gulf Coast beaches − and you may find a fish that is a true master of disguise.
