Transatlantic: Day 15 [Day 36]

As an introvert, I like to be either alone or with a small group (preferably one person) of people. Large crowds and big to-do’s just aren’t my cup of tea!

This year, for my 31st birthday, I had an introverts dream birthday party! I was as far as possible from any other person or stranger, and the only person there to share my birthday with was my wife.

This is our second day of being becalmed, so there are no waves, no winds, and no direction. We have nothing to run into and no one around us to hit us. We are alone and immobilized, aimlessly drifting where the currents take us. We spent the whole day relaxing, reading, watching movies, and cooking. No effort was made to move us faster as there was nowhere to go!

The clouds around us spoke of isolated regions of slight winds, but nothing that would be far reaching enough to be appreciable, so we just sat back and relaxed. Getting frustrated or angry will not make the winds change, so why waste the energy on such feelings. Instead, moments like this are wonderful for teaching you to relax and appreciate what is around you.

As a kid, Man-O-War would wash into the southern part of Puerto Rico every year. It was always late fall when it became dangerous to swim. Thankfully, the reefs would cause these siphonophores to retract their tendrils instead of having them stretched out into a web of pain. I always feared them and became very VERY good at spotting them, but I never really got to appreciate them.

These creatures are so unique, intricate, and delicate. I have always avoided them like the plague because I was either windsurfing, kayaking, or swimming. We are both merely visitors on the surface of the water in the reefs around Puerto Rico, but out here, here is their world and we are merely tourists passing through.

We would use what little wind there was to sail over to them and get a really good look at them. The intricacies of their sail, and the way they flop it up or lay it down into the water. Once you have a safe vantage point to observe these killing machines, these creatures really are quite beautiful.

My birthday has come to a close. We are still about 800 nautical miles from the Azores and have no way of knowing when we will start moving again. Yes, we are bobbing around on the surface of the ocean, but we are also relaxing and enjoying the respite from all the speed we had leading up to this.

Sailing fast is nice, but it makes daily life difficult. The boat is heeled over and you are constantly riding up and down waves. Cooking, cleaning, eating, and sleeping become rather difficult when you are skimming the surface at hull speed! This loss of all wind and speed was a wonderful gift from nature on my birthday. It let us relax and actually enjoy ourselves on this day out in the middle of the ocean.

Transatlantic: Day 14 [Day 35]

July 21, 2018, the winds vanished. The approaching high pressure system has come over us and we were not able to escape its path. We have no wind and no motion. Our speed through the water is generated by the current of the water we are in, and not by the winds.

Since the winds disappeared, the sea calmed until it looked like glass! On the surface of the ocean is what appears to be a white snowy substance. It was uniformly covering the entire surface, from the boat all the way to the visible horizon. Maddie got a beautiful picture of this Portuguese Man-O-War and you can see the powder that it shares the surface of the water with.

I took up a sample of the water with a mason jar, and the top inch is filled with microplastics. They cover the entire surface of the Atlantic Ocean, as far as we can see, and penetrate down about an inch. It was really heartbreaking to see how much plastic is floating out in the ocean. Out in the middle of the ocean, where you would think humanity hasn’t been able to influence yet; but the reaches of humanity are far and apparently have enveloped the top inch of the worlds surface with plastics.

The day passes on and the Man-O-War are the only reminder that we are not in another world. These creatures, which belong to the Siphonophores family, litter the surface of the ocean with their death traps set. They stretch their tendrils out almost 100 feet from the float, into an almost invisible thread of pain and torment. When something brushes up against it, the surface of the tendril explodes with hundreds of harpoons that deliver a painful toxin to its prey.

Why didn’t we go swimming when the ocean turned into a magical ethereal plain? Because we didn’t want to die a horribly painful death right next to the safety of our boat.

Portuguese Man-O-War

These "jelly fish" are both beautiful and terrifying.  Siphonophores Colonial Organism or Complex Organism

While they were thought of as jelly fish for some time, their exact classification has been under serious scrutiny lately. Due to their deep ocean living situation, studying their lifecycle has proven difficult, making it really hard to asses exactly what they are.

Portuguese Man-O-War are named so not because they come from Portugal, but rather because they look like the Man-O-War tall ship that the Portuguese used back in the age of sail. The creature has tentacles like a jellyfish, but instead of a bell filled with fluids it has a balloon. Instead of undulating the bell for locomotion, it raises a sail to the wind.

As if these creatures weren't interesting enough, their very classification as an organism has come into question. Portuguese Man-O-War are Siphonophores, but that is kind of the best we can do when it comes to classifying them. It turns out that the creature is more akin to a colony than a single organism. Each major part of the Man-O-War seems to be its own creature, capable of living on their own without the direct need of the other organisms. At the same time, each organism that makes up the "colony" is so highly specialized that it resembles tissues in different organs, making this a complex organism instead of a colony.

Sadly, this creature is so confusing and interesting that scientists still don't fully know how to classify it. Should it be a colony made up of obligate mutualistic organisms or is it actually a complex organism made up of various organs, and not various organisms? It seems like a simple question to ask and answer, but the various parts of the Man-O-War exhibit both traits and therefore it continues to perplex scientists.
