The Coral Sea is a rare example of a marine environment that is thriving.

Is that why you became a marine biologist?

The Natufians made (and presumably wore) beads and pendants in many materials, including gemstones and marine shells that had to be imported, and it is possible that this ornamentation actually reflects a growing sense of ethnic identity and perhaps some differences in personal and group status.

Well, apparently petroleum is usually made from simple, one-celled marine animals and plants, algae, for example.

Although the Aegean had been the birthplace of marine biology, its depths are now known to be exceptionally lacking in animal diversity.

Raised beaches often consist of areas of sand, pebbles, or dunes, sometimes containing seashells or piles of debris comprising shells and bones of marine animals used by humans.

Analysis of the shells themselves has confirmed the changes in marine topography, for it is only during the maximum phase that subtropical species of mollusc are present, indicating a higher water temperature.

Indeed, they have been called the marine version of the tropical rain forest, rivaling their terrestrial counterparts in both richness of species and biological productivity.

Although the vast majority of marine fishes are carnivores, in near-surface regions of high productivity the concentrations of larger phytoplankton (the plant component of plankton) are sufficient to support huge populations of filter-feeding sardines and anchovies.

They are home to lots of birds, fish and other marine life.

Fish probably originated in the oceans, and our first records of them are in marine rocks.

Although marine botanist W. A. Setchell suggested early on that temperature was critical to the growth and reproduction of eelgrass, it has since been shown that this particularly widespread seagrass grows and reproduces at temperatures between 2 and 4 degrees Celsius in the Arctic and at temperatures up to 28 degrees Celsius on the northeastern coast of the United States.

Petroleum is nearly always found in marine sedimentary rocks.

Similarly, a creeping glacier may gradually divide a population, or a land bridge such as the Isthmus of Panama may form and separate the marine life in the ocean waters on either side.

It wiped out many kinds of plankton in the ocean and many marine organisms that lived on the plankton at the base of the food chain.

The K-T event marked the end of the marine reptiles, such as the mosasaurs and the plesiosaurs, which were the largest creatures that had ever lived in the seas and which ruled the seas long before whales evolved.

I mean, think of…say, tropical or temperate marine environments, which have incredibly diverse fish populations.

Overall, about 38 percent of the families of marine animals were lost, with percentages much higher in some groups Ammonoid mollusks went from being very diverse and abundant to being extinct.

An extremely abundant set of planktonic marine animals called foraminifera largely disappeared, although they rebounded later.

The Army and Marine Corps have 80 systems in theater.

He is a solicitor specializing in marine law.

In Lebanon he was forced to retreat after the loss of 241 marines.

Difficult as it may be to believe, I was a marine.

The big coastal marine by Clarkson Stanfield is amazing.

They use the merchant marine to convert products.
