SEA Currents: celestial navigation

The Beginning of the End

Marcia Campbell, C-Watch, Eckerd College
Ocean Exploration

Hello world! To you, it’s Day 26 of our ocean voyage…but our watch rotations make for 18-hour days, so today feels more like Day 35 for us. It’s been one crazy rollercoaster ride having weathered out the effects of two cyclones but thankfully, the weather has finally steadied up a bit and both air and water temperatures are on the rise as we go farther north. Also, we broke 3000 nm today and are currently within 150 nm to the island of Raivavae!!!

Lost and Found at Sea

Anna Cerf, A Watch, Middlebury College
The Global Ocean

Growing up, I prided myself on having a decent sense of direction. I generally played the role of “navigator” with whomever I hiked, drove, or ran with.  I figured that coming into SEA Semester I would be able to transfer this ability and that hopefully it would help compensate for my complete lack of knowledge re: anything having to do with boats.

Almost Land Ho!

Stefani Johnson, B Watch, St. John’s University
Oceans & Climate

Hello to those reading this!

We are currently sailing under a beautiful waxing gibbous moon. It is shining just bright enough that most stars are not as visible as they usually are. Tonight is an interesting one; I can feel many mixed emotions - stress to meet the deadline of our final research paper and excitement to reach Dominica in the next two days. A bet has been made for when we expect to see land and the winner gets to shout “Land ho!” As you can see, these are some pretty high stakes we’re betting for.

Sailing by the Stars, Wind and Seas

Robin Kim, C Watch, Boston College
Oceans & Climate

We are more than 24 hours into our non-instrument run, and hence the unavailable current position. Hopefully the stars, wind, and seas have been guiding us correctly to our port stop in Dominica, soon to appear in a few short days! Just a month ago, most of us had never even set foot on a sailing ship; tonight, we are the ones steering the helm and calling the sail plans, all without the help of a compass or GPS. Of course, then there is the slim chance of making landfall on a different island or continent altogether.

Turning West with New Challenges Ahead and the Stars Above

Arthur Davis, C Watch, Sailing Intern, SEA Alumni, S-258
Oceans & Climate

We have turned to the west! Since leaving the Canaries, we have been working our way generally to the south and west, plowing our way through the Canary Current that flows down the northwest coast of Africa, crossing through the corner of the North Atlantic Subtropical Gyre that lies in the center of North Atlantic, and now we find ourselves in a new “general locale” (as we call it in lab!): the North Equatorial Current. This current, along with the easterly to northeasterly trade winds will (knock on wood) take us across the 15th parallel of northern latitude on our way to the Caribbean.

Exam Day

Anna von Brandis, A Watch, Christian-Albrechts-Universität zu Kiel
Oceans & Climate

Can a day end any better than by sitting on the spreaders, watching flying fish and enjoying the endless blue? After two days and nights with squalls and lightning, the sun finally found her way back to us! The wind is blowing constantly but from the wrong direction for us, so we spend another day motor-sailing. Strategies of how to get the wind to be more cooperative are frequently discussed - so far without success. As a sailor from the Baltic Sea, I am used to tacking a lot and frequently getting the wind on the nose…but I wasn’t expecting to have this problem in the tropics!

Shooting the moon! And sun! And stars! And even some planets!

David “Rocky” Bonner III, C Watch, 3rd Mate
Ocean Exploration

Today those of us on C watch had the morning watch. It was a comfortable 19°C as we took the deck with beautiful clear skies. For me, and for most of the rest of the watch, the theme of the day has been celestial navigation.

We were fortunate to have a lovely crescent moon high in the clear sky upon taking the watch, not to mention the sun itself. This gave us an excellent opportunity to get a two-body celestial fix. Fairly shortly after getting settled in, Yen and Kate grabbed some sextants and shot the sun and the moon. Hearts players beware, they both shoot the moon like pros.

Auckland or Bust

Ben Eliason, C-Watch, Villanova University
SPICE

We’ve spent around four weeks aboard the Seamans now and it finally feels like we are getting used to living here. We have 11 more days until Auckland and I think we are more than ready for the challenge of sailing there. There is still so much to learn but we have mastered the daily routine of life at sea. Things that were hard at the start have become second nature for us now. It’s nice to be able to talk like a sailor and handle some of the sails without having to stop and think about it first.

It happens every day…

Sara Martin, A Watch, Chief Mate
SPICE

Since departing Tonga we’ve seen some beautifully clear skies, and therefore had opportunity for the first few star frenzies of the trip.  You—dear reader—might well ask, “What the heck is a star frenzy?” and you would not be alone; many students were asking the same question mere hours ago here aboard Seamans.  Some of those students are now veterans of two star frenzies, and already eager for more.

3 Things I’ve Learned Aboard Seamans

Madelyn Cook, A Watch, Kenyon College
Ocean Exploration

Hello again from the SSV Robert C. Seamans, and happy May Day! Time sure has flown while at sea, and we are all excited to reach the many milestones of our cruise track which the month of May has in store. Knowing that we will soon be able to cast our eyes on the wonders of Raiatea, Moorea, and Tahiti (which I’ve heard are just lovely) has the ship in good spirits, and the students have been walking around with a palpable sense of pride and excitement as rotations through the JWO and JLO responsibilities continue, giving everyone a chance to have control of the deck in 6 hour increments, which means giving the necessary commands and always abiding by the ship’s standing orders to get ourselves where we need to go safely, happily, and responsibly.
