Coral at Kealakekua Bay

Here’s the promised one-minute drone video from yesterday’s visit to the Captain Cook memorial.

If you think that that Fair Wind tour looks like a lot of fun, you’re right. (No, they are not paying me for the plug. In fact, the crew were not altogether happy to see the drone hovering nearby.) A couple of things are worth noting, notably the proliferation of coral and the stunning clarity of the water. The imagery is not enhanced: it really looks like that. But I have already noticed in increase in the amount of coral bleaching over the years; it is due to both rising water ocean temperatures and some of the ingredients in many sunscreen lotions. Those would be oxybenzone and octinoxate, which interfere with coral reproduction and cause bleaching, and butylparaben, a preservative that may also  cause bleaching. Hawaii has banned the first two, starting in 2021. Interestingly, a lot of dermatologists were opposed to the ban, fearing that it would discourage people from using any sunscreen at all. But in fact the transition has already begun, and the stores are full of reef-safe sunscreens. Their active ingredients are those old standbys, zinc and titanium oxides.

I would also like to bring to your attention one other Captain Cook-related fact that I forgot to mention in yesterday’s post, namely that in addition to his human crew Cook had on board what may be the most well-traveled goat in history.  In 1766, two years before Cook’s first voyage (he reached Hawaii on his second), the HMS Dolphin circumnavigated the globe under the command of Capt. Samuel Wallis. On board was the biologist Joseph Banks, who had brought along his goat to provide milk for the crew. If this were to happen today, Banks would have to pay a $25 Goat Surcharge and store the beast underneath the seat in front of him. But in this case no surcharge was applied and the goat became the first caprine to sail around the world. (It is also the reason that you are now looking up the word “caprine” in the dictionary.)

Two years later, Cook invited Banks on his voyage as well. Banks accepted… and brought along the same goat, which consequently circumnavigated the globe again, this time on the HMS Endeavour. Cook brought the animal home to his farm in England after this voyage, where she lived out her days in unheralded peace. According to Cook’s diary she died on March 28, 1772. Nobody knows the goat’s name. Today she would have an Instagram account.

The Movable Border

We all know that national borders can be fluid things, influenced by political events, wars in particular. But the border between Italy and Austria is the only one that I know of that has to be recalculated on a daily basis due to climate change. Yep, it’s true. The border between the two countries is agreed to be determined by a line across the watershed, but because the glaciers are retreating the watershed is moving. This actually became an issue in September of 1991 when Ice Man Ötzi was discovered very, very close to the border, and it was not clear which country actually owned him.

A careful survey revealed that as of the time of the discovery Ötzi was on the Italian side of the border, but only barely: he’s an Italian citizen by 97 meters (318 ft). (But in a masterstroke of international diplomacy, the Italians agreed that the forensic analysis on Ötzi would be done in Innsbruck, Austria.)

Today, the border is tracked by a network of sensors and GPS receivers and is recalculated essentially continuously. If you go upstairs from Ötzi’s body in the South Tyrol Archaeological Museum you can even let a computer draw you your very own map of the border du jour that you can take home as a souvenir. Here is the drawing end of the apparatus (a Google image; photos were not allowed):

border drawerThere is a pile of local topographic maps next to the table. You pick one up, lay it on the table, and as soon as the device senses that it is there it activates the drawing armature and draws that instant’s calculated border on it in a red marker, labeling it with the current date and time (which you can see at lower right).

Remember this the next time you have a property line dispute with your next door neighbor.
