Bioluminescence


Bioluminescence

Fireflies light up due to bioluminescence: the ability of living organisms to convert chemical energy to light energy. Bioluminescence is also exhibited by some fungi, mollusks, and worms, and bioluminescent fish are common in the ocean’s depths, likely because the light aids in species recognition in the darkness. Other animals use luminescence in courtship and mating, to divert predators, or to attract prey. Why is most marine bioluminescence in the blue and green part of the spectrum? More… Discuss

news-nature: Fish Filmed at Record Depth


Fish Filmed at Record Depth

Researchers exploring the depths of the Mariana Trench recently set the record for deepest fish ever filmed—and then broke the record during the same study. The two newly discovered species of snailfish were filmed by a team from the University of Aberdeen in Scotland using several remotely controlled submersibles. The second fish was filmed more than five miles below the surface—a depth of 8,145 meters. Researchers say the fish is very fragile and does not like look like any known species. More… Discuss

Edward Flanders Robb Ricketts (May 14, 1897 — May 11, 1948) commonly known as Ed Ricketts, was an American marine biologist, ecologist, and philosopher. He is best known for Between Pacific Tides (1939), a pioneering study of intertidal ecology, and for his influence on writer John Steinbeck, which resulted in their collaboration on the Sea of Cortez, later republished as The Log from the Sea of Cortez (1951).

today’s birthday: Rachel Carson (1907)


Rachel Carson (1907)

Carson was an American writer and marine biologist. Her book Silent Spring, a provocative study of the dangers of certain insecticides, is generally acknowledged as the impetus for the modern environmental movement. In other well-known books on sea life, such as Under the Sea Wind, she combines keen scientific observation with rich poetic description. What did Carson’s marital status lead former Secretary of Agriculture Ezra Taft Benson to conclude about her political leanings? More… Discuss

MOLASSES SPILL CHOKES HAWAII HARBOR


Molasses Spill Chokes Hawaii Harbor

Unfortunately, we know all too well the damage an oil spill can do to an ecosystem, but how about molasses? The sweet, sticky stuff used in cookies, candies, and other tasty treats has caused an environmental disaster in Honolulu Harbor. A massive spill from a molasses pipeline earlier this month sent hundreds of thousands of gallons of the heavy syrup into the harbor’s waters, killing thousands of fish. Unlike oil, molasses sinks in water, and experts have no way of removing molasses once it has been spilled. The full impact of the spill on marine life will not be known for some time. More… Discuss
