Science and Technology Log

You never know what you might see first thing in the morning! When I awoke and looked out my porthole I saw this in the distance.

The volcano has been active for the past few months, but I saw no smoke today.  You can check out volcanic activity at  http://www.avo.alaska.edu/activity/Veniaminof.php

We cast off yesterday morning at 1000 hrs, RST—Rainier Ship Time.  Although we are still in the Alaska Daylight Savings time zone, our time on the ship has been adjusted backwards 1 hour to give us more daylight during ‘working hours’.  Since the ship is its own floating universe, time that is referenced to a specific time zone is not as important as time that is referenced to our day and the work that needs to be completed.  Einstein would be pleased to see that time is, indeed, relative here aboard the Rainier!

There is science involved just to leave port and set forth on this cruise.  There’s data to be collected, such as a weather forecast—and decisions to be made based on that data.  Today’s weather report called for rain and high winds.  That data input resulted in a travel plan including taking a more protected route north of Kodiak Island instead of heading out to more open water right away.  We didn’t reach the wide-open spaces until evening, and I was lulled to sleep by the endless rocking and rolling of the boat.

Science can also include the protocols needed to keep everyone on board safe and healthy during a cruise.  With that in mind, I spent part of the day learning about the ship and the safety routines we need to follow.  Ensign Wall gave me my survival suit, aka Gumby Suit and showed me how to don that lifesaving apparel.  The suit is a foam-filled drysuit, providing insulation and floatation in one handy, non-form-fitting package.  They are, apparently, one size fits none, but when it’s a matter of survival, I doubt that style counts for too many points!

Each person aboard is assigned stations to report to in case of fire or in case it becomes necessary to abandon ship.  I found out that I go to the Boat Shop near the stern in case of fire, and that I head to Station 1 near the bridge.  We had a fire drill in the afternoon, followed by an abandon ship drill.  Much like fire drills at school, it’s a good time to practice and figure out the best way to get to where you need to go.  Since I’m still learning my way around the ship, it was especially important to figure out where I needed to go and how to get there.

Then there’s the ‘real’ science—the science of hydrography and the point of this entire venture.  The NOAA Ship Rainier has been tasked with charting (creating maps) of the Shumagin Islands and Cold Bay areas. It’s amazing to think that there are still some parts of our coastline that haven’t been charted.  I spent much of this afternoon talking with the scientists who are making these maps and came away with the overwhelming sense that this is, indeed, a complicated and multi-faceted process. I’ll be writing separate journals on all the science that goes into creating these detailed maps of the ocean floor.  If you just can’t wait and need to know more right now, check out the blogs from previous TAS teachers on the Ship Rainier.

Personal Log

Much of my first day at sea was spent getting used to being aboard a large floating object on a rather bumpy sea.   Our day was spent in transit, from Kodiak to the Shumagin Islands, around 28 hours away.

There’s a lot to learn about life on board the Rainier.  Most important has been orienting myself and figuring out where everything is located.  Decks are labeled from ‘A’, the lowest, to ‘G’, the uppermost deck area. My quarters are on the ‘E’ deck.  The Galley, where food is prepared and served, is on the ‘D’ deck below me, and the Bridge (steering and control of the ship) is above me on the ‘F’ deck.

I have my own room—kind of luxurious living!  There’s a bunk, the head (bathroom), a couple of closets, drawers, and even a small fold-down desk area so that I can write my journals.  Every drawer latches tightly to minimize the chance of unidentified flying objects if we hit some rough weather.

Home, sweet home.
Home, sweet home.

I took a short tour of some of the more esoteric parts of the ship, including a visit to the cofferdam, whose access was through a hatch and down a ladder hidden in one of the heads (bathrooms).  This is sort of like accessing the crawl space under your house through a small tunnel in your bathroom.  While we speculated on just what purpose this area served (storage, poor planning in designing the hull and layout, a random skinny place to hang out?), it turns out that it is a watertight compartment that separates the contact between liquids that might be in the bow area and those in the stern area of the ship.

There was also an escape hatch that was incredibly heavy to lift—but I am sure you could lift it if your life depended on it!  I don’t plan on having to test this thing out!!

Flotsam and Jetsam “Never bring anything onto a boat that you can’t afford to lose.” (Nancy Church – Cape Cod Museum of Natural History)

Except for the anchor, there are very few items that go overboard intentionally on a ship. A hat blown off your head by the wind becomes flotsam, but something deliberately discarded is jetsamARGO  is the international program that deploys and monitors a global network of autonomous floats that monitor ocean conditions (“Taking the pulse of the oceans.”). The buoys are deployed from a variety of vessels and one of the main advantages is that a vessel does not have to slow down or stop to launch them. Because of this, a vessel dedicated to research is not required, and commercial and even cruise ships have participated in this world-ocean study.

Drifter currents

Drifters have been distributed since 1999 and continuously monitor temperature, salinity and currents. They will provide a global network spread out on a 3º by 3º ocean grid (180-miles by 180miles). Data transmitted automatically to satellites is broadcast to the Global Drifter Program and available continuously to researchers.

Teachers and students also are involved through the Adopt-a-Drifter Program and we deployed drifters marked with decals from two schools partnered through it: Universite Nancy (France) and Grandview Elementary School – Grades K, 1, 2, 3, 4, 5. Drifters actively transmit data for over a year, but like anything in the sea, can become the home for bio-fouling organisms that can interfere with their operation. We deployed several of them. The simplest are blue-andwhite basket ball-sized floats with a drogue (a large sock-like bag) that acts as a sea anchor or drift sock so that the movement of the drifter is by current, not wind. Once in the water, the packing materials dissolve, the drogue sinks to about 15 meters, and the currents, satellites, scientists and students do the rest. All researchers have to do to explore the oceans is log-on to the drifter website with a computer.  

“After the sea-ship, after the whistling winds… Toward that whirling current, laughing and buoyant, with curves… (After the Sea-Ship – Walt Whitman)

Other larger drifters are shipped in sturdy but degradable cardboard cartons. These too are launched off the stern and the shipping boxes rapidly fall apart after the water dissolves the glue. They are rather mysterious since we did not actually see what they look like, but I’ve seen others in the repair shop at WHOI (Woods Hole Oceanographic Institution). They are tube-shaped and designed to automatically sink to as deep as 1000-meters, and then rise periodically to broadcast their data. What a wonderful journey they will have to share with the world when they start reporting their data in dark and stormy seas and on sunny days. Falling away astern of us, floating high and looking coffin-like, I was reminded of Queequeg’s casket and some of the most memorable lines from Moby Dick:  “These are times of dreamy solitude, when beholding the tranquil beauty and brilliancy of the ocean’s skin; one forgets the tiger heart that pants beneath it…”

Drifter in the water on its way!
Drifter in the water on its way!

We have had a great string of days. I have settled into an interesting work routine with  helpful and interesting scientists and crew. Weather balloons and sondes are released every four hours and the readouts from their fights are very informative. Along with the evening lectures, the week has been like a short semester on meteorology. Hourly water sampling has gone well too, and we are learning more about these peculiar eddies of warm and cold water each day.

My roommate (RW) is very nice and accommodating, and since we work different hours and find the best way to relax is with headphones and a book, the room does not seem crowded at all. There are a few items I am glad I brought, and I suggest they be added to the TAS list: coveralls, ski cap, knee pads and eye drops. The coveralls are great for cool mornings on deck and to quickly pull on for the weekly “abandon ship” drills, since you are required to report to your muster station in long pants and sleeves, and with a hat. My light-weight volleyball knee-pads are good if I have to kneel on the metal deck for a while to take pictures. And eye drops are a relief since we do get wind almost every day, and some very bright days since we are headed into the Austral Summer, and the sun’s position is moving south every day.

I have been checking my Almanac, and perhaps as early as tomorrow, our course will cross paths with the sun’s southern movement, and it will be directly overhead at Noon. This can only occur at locations in the “Tropics” (Between the Tropic of Cancer and Tropic of Capricorn) and I have heard sailors refer to it as a “Lahaina Noon.” This term comes from the old sailing days when whalers made port stops at Lahaina on Maui. When it occurs there, fence posts, and for that matter, people, do not cast a shadow. Hopefully the clouds will clear around midday and we will be able to see the phenomenon.

“Thus drifting afar to the dim-vaulted caves Where life and it ventures are laid, The dreamers who gaze while we battle the waves May see us in sunshine and shade.” (Sun and Shadow by Oliver Wendell Holmes – 1857)
