Our favorite sea monsters – Scylla and Charybdis (#2)

September 9, 2010September 2, 2010 Bluegrass Blue Crab

Scylla and Charybdis team up to make passing through the Straight of Messina impossible – to be a safe distance from one meant being too close to the other. They were one of Odysseus’ many challenges during his epic journey. Scylla is a six-headed monster storied to have become that way after poisoning by the jealous wife of Poseidon who captured sailors off their boats and ate them. Charybdis is best described as a whirlpool bringing ships to the bottom of the sea. She was the daughter of Poseidon and converted by Zeus.

There is a place in the Atlantic where ships vanish, where planes fall from the sky, where vast, inexplicable mysteries haunt the sea. The Bermuda Triangle, darling of mysterious disappearance buffs. What causes all these weird disappearances? Numerous hypotheses have been put forward, from aliens to methane bubbles, to magnetic anomalies. Unfortunately, the real answer … Read More “Ocean of Pseudoscience Shorty – The Bermuda Triangle” »

Reader mail: Shark Fin propaganda

September 9, 2010August 31, 2010 David Shiffman 1 Comment

Science

Last weekend, longtime SFS reader Suzy sent me an interesting question. Suzy is Asian, and though she is a committed conservationist, several members of her family regularly eat shark fin soup. One relative just sent her a copy of a news article entitled “Shark Fin Soup: Eat it without guilt” (available here). Suzy asked me if the information in this article is correct, and how she should respond to her family members.

Though it is a few years old, I had never seen this article, and it’s a little shocking. I don’t know if I’ve ever seen a better example of distorting or ignoring science to promote a political agenda outside of Fox News. In short, Suzy, most of the information in here is either false or intentionally misleading.

Ocean of Pseudoscience Shorty – Pickles for Seasickness

Uncategorized

My grandfather, who was on board Marine ships from 1928 through the Korean War, used to suggest eating pickles for seasickness. During my recent cruise in the Sargasso Sea, I finally had a chance to test his theory and it worked. Was it just a placebo effect, was it the vitamin C, or something else … Read More “Ocean of Pseudoscience Shorty – Pickles for Seasickness” »

Our favorite sea monsters – The Giant Manta Special Edition

Conservation, Science

Sea Monsters, mythical beasts of legend and lore that ply the world’s oceans, sinking ships, terrifying sailors, swallowing entire crews whole. Sea monsters occupy a special place in our imagination. The ocean is huge, unfathomable. Of course mighty beast could dwell within, undetected.

Every once in a long while, the myths, the legends, the stories, turn out to be true. This is one of those times.

Our favorite sea monsters – Aspidochelone (#3)

Though the Aspidochelone is not as well known as some other sea monsters, the story surrounding it is so awesome that we had to include it on our list of favorites.

According to legend, this crafty turtle/whale/fish (the story varies between cultures on this point) is so big that sailors think it is an island. Excited to see land after so much time out on the water, sailors make landfall on the Aspidochelone. The beast then submerges, taking the unsuspecting sailors with it to the depths.

Maximum (un)Sustainable Yield

September 8, 2010December 20, 2011 Bluegrass Blue Crab 10 Comments

Science

In 1954 and 1957 Gordon and Schaefer respectively described the idea of maximum sustainable yield (MSY) – that is, the amount of fish that could be taken by commercial fishing operations to maximize reproduction by the system year after year. Since then, it has been heralded as the mathematical panacea to fisheries management.

Gordon and Schaefer also described the maximum economic yield which threw price relations into the mix. It describes the point at which the fishers will make the most money, accounting for revenue and their expenses. Note in the graph below the fold that the maximum economic yield (MEY) is below the MSY in terms of effort. Gordon and Schaefer imagined a private manager or government overseer that could calculate the MEY and regulate fisher behavior in order to meet it. The idea was meant to be win-win for the fishers and the fish.
