The Posts on this page are the summaries for the courses developed by Marine Archaeologist Yvonne-Cher Skye while living aboard the Mary and Bill of Rights in Chula Vista, California, U.S.A.. It consists of 21 aspects of Marine Anthropology which can be taught in a seminar single-day format or over an 18-week semester. The supplemental materials will be available for purchase via paypal or credit card on her webpage located at the YGFI- Your Girl Friday International Website. Links to individual modules and their introductions will be posted on this page, as well as on the Skye Research Page on YGFI's website. To gain a better understanding of the courses that are offered, please read the introduction page here. Follow the links to the other posts which will provide links to the specific page on the website to purchase that module. At the present time, they are provided as an entire package, which includes:
- Course Outline
- References available
- Summary of course to promote to students and the public
- Video list of related topics
told Al Jazeera. “There is no life out there.” Many of Louisiana’s oyster harvest areas are “dead or mostly dead,” he says. In Mississippi, fishing boats that used to catch 30 sacks of oysters a day are returning to docks in the evenings with fewer than half a dozen sacks aboard. It’s not just oysters. The entire fishing industry is being hit, with catches down and shrimp and shellfish being discovered with disgusting deformities. One seafood business owner told Al Jazeera that his revenue was down 85 percent compared with the period before the spill. From the article:If it’s true that oysters are aphrodisiacs, then BP has killed the mood. Louisiana’s oyster season opened last week, but thanks to the mess that still lingers after the 2010 Deepwater Horizon disaster, there aren’t many oysters around. “We can’t find any production out there yet,” Brad Robin, a commercial fisherman and Louisiana Oyster Task Force member,
“I’ve seen a lot of change since the spill,” [Hernando Beach Seafood co-owner Kathy] Birren told Al Jazeera. “Our stone crab harvest has dropped off and not come back; the numbers are way lower. Typically you’ll see some good crabbing somewhere along the west coast of Florida, but this last year we’ve had problems everywhere.” Birren said the problems are not just with the crabs. “We’ve also had our grouper fishing down since the spill,” she added. “We’ve seen fish with tar balls in their stomachs from as far down as the Florida Keys. We had a grouper with tar balls in its stomach last month. Overall, everything is down.” According to Birren, many fishermen in her area are giving up. “People are dropping out of the fishing business, and selling out cheap because they have to. I’m in west-central Florida, but fishermen all the way down to Key West are struggling to make it. I look at my son’s future, as he’s just getting into the business, and we’re worried.”Ecosystem recovery is a slow process. Ed Cake, an oceanographer and marine biologist, points out that oysters still have not returned to some of the areas affected by a 1979 oil well blowout in the Gulf. He thinks recovery from the BP disaster will take decades.

The Pacific Ocean is a pretty darned big place. The hull of the 72â€™ former racing yacht, Sea Dragon, not so much, especially when crammed full of research equipment and 14 full-sized human-type people not necessarily accustomed to the rigors of the open ocean. But thatâ€™s just what the intrepid team of oceanic avengers from the 5Gyres Institute are up against as they race across the Pacific on a collision course with the great field of debris washed away from Japan by last yearâ€™s devastating Tohoku earthquake and tsunami.
Imagine cramming into an RV and driving from Nome, Alaska to Tierra Del Fuego with the cast of Road Rules Season 9. (That would be the Maximum Velocity Tour, but Iâ€™m sure you knew that, gentle reader.) Now try to imagine that the I-5 is heaving 30 to 40 feet into the air, is full of sharks, and generally wants you dead. Add to that, Theo wonâ€™t stop spraying you with the super soaker he brought for some reason, and youâ€™ve got a pretty good idea of the potential horror involved here.
Scientist, adventurer, and Gulf War veteran Marcus Eriksen previously floated the length of the Mississippi on a raft made of plastic bottles and sailed from California to Hawaii on a boat made of trash to raise awareness of the pollution problem facing us all. What he saw changed his life. â€œI couldnâ€™t believe how much waste was littering our coast lines,â€ he says.
Eriksen and his wife, Anna Cummins, co-founded the 5Gyres Institute in 2009 to study the Earthâ€™s 5 great subtropical gyres â€“ enormous, slow-moving whirlpools on the oceanâ€™s surface â€“ and raise awareness of the horrifying levels of garbage floating within. These great pelagic depressions (I think I just named Jimmy Buffetâ€™s next album) serve as the Earthâ€™s mighty bellybuttons, collecting all sorts of unwanted refuse, the vast bulk of it, plastic.
The most infamous of these gyres holds The Great Pacific Garbage Patch, and while the notion of an island of garbage a thousand miles across is an exaggeration, what is actually out there might be far more insidious. â€œThose 5 gyres make up about 21 percent of the planetâ€™s surface, and they are covered in this thin confetti of plastic,â€ says Eriksen, who has trolled for trash across the high seas.
This confetti, made of particles the size of fish-food, is often coated with a thin layer of industrial chemicals and petroleum, creating little poison pills that fish in turn eat and absorb. But very little is known about how this stuff travels, and thatâ€™s where the tsunami debris comes in.
Some of the debris has already made landfall in North America, most notably a Harley Davidson discovered on a Canadian beach earlier this year (perhaps the first time a Harley has made it over 4,000 miles without breaking down) and shockingly, a 66 foot-long concrete dock covered in millions of invasive organisms that washed up on the Oregon coast.
But according to Eriksen, this debris is only the vanguard. â€œThe stuff washing up in British Columbia right now, that is the stuff affected by wind,â€ he says, speaking via satellite phone, noting that anything peeking above the surface of the Ocean acts as a sail, speeding its journey east. â€œBut whatâ€™s subsurface, whatâ€™s beneath the waves, hasnâ€™t made its way across yet.â€
For an organization dedicated to studying the effects of plastic pollution in the sea, last yearâ€™s catastrophe provided a unique opportunity. â€œYou donâ€™t often get a chance to take an entire city, put it in the ocean, and see what happens to all the stuff,â€ Eriksen says. â€œThatâ€™s what happened here.â€
Eriksen and his team of scientists, journalists, and environmentalists sailed from Yokahama Japan on June 10. They sailed half way across the ocean until finding their first piece of tsunami debris on June 17, then turned south to travel the length of the debris field. â€œWhatâ€™s left behind is going to be plastics and anything thatâ€™s trapping air, say lightbulbs, car tires still on the rim, insulated refrigerators, boat hulls,â€ Eriksen says.
Eriksen says the stuff should help answer some questions: â€œWhatâ€™s the impact on marine life? How much is out there, and what kind of pollutants are sticking to the materials that are left behind? Are there going to be mountains of trash washing up along the Hawaiian beaches a year from now?â€
In the meantime, Dr. Eriksen and his shipmates are bunking a foot from their boat-mates, spending a goodly portion of their days heaving along with their storm-tossed decks, and all in the name of a cleaner, plastic-free sea.
