On the Edge of the North Pacific High, aka The Great Garbage Patch



1579 nautical miles due west of Santa Cruz, CA

Typically, summer brings a large stable high pressure zone to the Eastern North Pacific Ocean.  Currents and winds swirl clockwise, circling up past Japan, eastward across the Aleutians, down the North American coast, and back along the equator.  At longitude 155 W, we are sailing the western edge of this high at a snail's pace of 3.2 kts. (3.7 mph).  We could walk that fast!  It isn't speedy, but as we go 24/7, we will make around 75 miles today.  It will be several days before we are back in the wind, but we hope not to use the motor.

This is the edge of the area known as The Great Garbage Patch.  When we traveled the South Pacific, we saw some bit of trash such as a grocery bag or a plastic bottle, almost daily and plastics were splattered on atoll beaches.  Here in the North Pacific, we see plastic almost at any time, even though we are only on the edge of the patch.  We look out and see fishing buoys, bottles, bags, pieces of rope (we had to pull one out of the water generator blades), packing peanuts, and smaller unidentifiable pieces floating just under the surface.  Very few people have actually traveled through the center of the patch, as there is almost never any wind there.  Motoring through an area that large and polluted would be problematic.  Catching a line in the prop could be a nightmare.  Imagine having to dive under the boat mid-ocean to cut lines!  With six five gallon fuel cans strapped to the side of the boat and a 35 gallon tank, we have a 65 gallon fuel capacity.  Motoring would cost precious fuel and possibly cause prop trouble, so, we sail ever so slowly as we edge by this high.  We are led by our parasailor spinnaker which billows gracefully before us.

Research tells us that China is the greatest contributor to the patch.  Americans produce far more trash per person than any nationality but we also have the best recycling and trash disposal system in the world.  However, we saw scant evidence of recycling in the towns and cities of the west coast as we traveled down it and almost none in Hawaii.  Most places had residential recycling, but opportunities for recycling for businesses and public areas was non-existent.  It reminds me to be more diligent about reduce, reuse, and recycle.

It is getting cooler as we travel north.  Ocean temperature was 86 in the Tuamotus, but is 76 here and getting cooler by the day.  We have started adding layers of clothing to night watch, but day is still hot.  Aside from the plastic, the sea is also scattered with thousands of small man of wars, their bulbous bodies blown along by their tiny sails with stinging tendrils trailing below.  A large school of fish are feeding on the surface.  We can't tell if they are striking the man of wars, the packing peanuts, or something unseen.

We drift quietly on at our snail's pace, saddened by the state of the sea.

 Portugese Man-o-War:
 The Portuguese Man o’ War, also known as the Bluebottle, is a jellyfish-like marine invertebrate of the family Physaliidae. Despite its outward appearance, the Man o’ War is not a jellyfish, but a siphonophore. Siphonophorae differ from jellyfish in that they are not actually single creatures, but colonial organisms made up of many minute individuals called zooids. Each of these zooids is highly specialized, and, although structurally similar to other solitary animals, they are attached to one another and physiologically integrated to the extent that they are incapable of independent survival.
