The first sail without engine
was not long. Saturday 16 April, Twister sailed from Elsesro Marina near the Bergen city center to Ebbesvik on Lille Sotra island (about 10 miles) with LT at the helm and Henriette as first mate and all-around fender-offer. The marina is being demolished to make room for luxury condos, so the boat gypsies who had made it their home are scattered to the four winds. The sail to Ebbesvik was very pleasant though chilly. We were becalmed for a short while under the Askøy Bridge (where the police responded to aspiring jumpers about 60 times last year). Aside from that I could hardly have asked for better conditions. Approaching Ebbesvik, I found the public concrete dock occupied. The private wooden dock nearby was empty. After one reconnaisance pass we charged into the narrow cove, came about and pointed the bow right at the dock as Twister lost her forward momentum. I stepped off with a dock line in hand very pleased with myself. The motorboat occuping the public dock kindly offered to move allowing me more practice docking under sail. As we neared the concrete wharf I furled the jib and tried out the new skulling oar which turned out to be worse than useless. It honestly seemed I managed to make the boat go backwards. Skulling with the rudder, the tried and true method with Twister, was sufficient to maneuver her alongside. So far I'm feeling good about engineless sailing.
Since Saturday I have been continuing the interior redecoration started when I removed the engine and fuel tank in October. The port side freshwater tank was removed using a drill, hand saw, crow bar, and liberal amounts of elbow grease. I also pulled out the old electrical panel and wiring (in retrospect I wish I had looked a little more carefully at how things were connected before I started yanking things out). The rough plan is to move the galley and chart table aft making room for two traditional settees (boatspeak for couch) in the middle of the cabin. The pilot berth will also be moved aft into the space formerly occupied by the fuel tank (I will not miss the smell of diesel).

Dispatch From A Drilling (Coring) Ship
It's easy to forget one is on a ship aboard The JOIDES Resolution (named after Captain Cook's ship, she has crisscrossed the world's oceans in a manner befitting the name). The accommodations are bordering on luxurious, and most days the motion of the ship is hardly noticeable. Launched in 1978 with a major refit in 2007-2008 she is 143 meters long. Currently
there are 125 people on board (now 124 after a medivac). It is like a floating city.
JOIDES Resolution, aka "JR" coming into Port Louis, Mauritius |
The rig can drill in a water depth of ca 8000 m and then another 2000 m below the seafloor. On this expedition we have drilled in around 3000 meters depth and collected cores down to ca 300 meters below the sea floor. Carrying, cutting, and archiving sections of cores all day (which is mostly what I do), one can lose sight of the bigger picture. The sediments we are collecting were deposited up to 7 million years ago and tell the story of past climates. Paleontologists identify fossilized remains of benthic and planktonic foraminefera, diatoms, and radiolaria. Other specialists measure the the magnetism in the cores (the polarity of the earth's magnetic field has flipped many times in the earth's history). Combined with gamma ray emission, gamma ray transmission (measuring density), and other techniques these data allow scientist to date each section of sediment. Once the cores' ages are determined more detailed measurements are used to reconstruct the climate. The purpose of this expedition is to study the past behavior of The Agulhas Current and its influence on the climate (see this BBC blurb). As I write this, we are steaming north in The Mozambique Channel (between Mozambique and Madagascar) towards our next coring site.

14/04/16--I just came across co-chief scientist Sidney Hemming's blog from the cruise. She obviously has a much better idea what's going on that me: http://www.ldeo.columbia.edu/research/blogs/when-oceans-leak
And this map shows the ship's circuitous track during the expedition (ask my why the track looks like it does):

Back in Punta Arenas
The ASRV Laurence M. Gould arrived Punta Arenas this morning after the smoothest crossing of The Drake Passage I have experienced. There was a good amount of ice in the vicinity of Anvers Island (the area where we were working) for this time of year. Some photos from the cruise here.

Project Blog
The sun came out today so I took some photos. We are in Andvord Bay
where most of our sampling is happening. It is a fjord of sorts and very
sheltered from the open ocean, so life aboard is very comfortable these
days. Several glaciers descend into the water and the bay is littered
with icebergs and bergy bits. If you want to read more about the project
I am a part of, check out the official blog:
