Science and Technology Log 

The dredge caught a monster lobster today.  The scientists seemed to think it was more than twenty years old. When held up it was the size of an adult’s length from shoulders to knees, and two hands were needed to hold it!  A spiny dogfish (looks like a shark) was also caught. I held it to have my picture taken and I plan to hang it on my classroom door! Otherwise the catches were the usual—some with lots of rocks, some with sand, others with many star fish or skates.  All these fantastic sea creatures that I have only seen in books have become part of my life here on board the ALBATROSS IV.  The star fish and hermit crabs are my favorites, skates are cool to look at and pick up by the tail and put in the bucket, goosefish (known as monk fish in the grocery store) have a face that “only a mother could love”, and the scallops, even though I’ve seen thousands of them are each a little different.

Personal Log 

Sunset was beautiful again tonight and the moon is spectacular.  With my binoculars the craters were very clear. A lone seagull followed us for a while; his white body against the black sky would have inspired me to write a poem if I were a poet.  Hard to believe the adventure is coming to an end, and what an adventure it was.  The crew has been super, very kind, and willing to talk and answer questions.  The scientists have an important job collecting and recording data; they are an interesting group to work with.  Thanks to all for making my time on the ALBATROSS IV the adventure of a lifetime.

Date: August 8, 2006

Data: (collected very early morning, 3AM) 
Air temperature = 18 C0 (65 F0 )
Water temperature = 18.9 C0 (68 F0)
Weather = rain
Depth of trawl = 98 meters (remember, a meter and a yard are pretty close)
Water salinity = 31.28 ppm
Wind speed = 18 knots

Science and Technology Log 

We have been very busy collecting samples of scallops and fish.  We are weighing and measuring the scallops.  Some of the dredge amounts are huge so we collect all the scallops and take a sub-sample and weigh and measure those.  Another sample of scallops is cleaned, measured and frozen to determine the age of the scallops which is done at a lab on shore. We collect cancer crabs and starfish and count them as they eat scallops and we want to see the amount of predation. We are covering all 24 hours so there is a day watch from noon to midnight, and there is a night watch (mine) from midnight to noon.  When you eat a scallop, you are eating the abductor muscle.  This muscle can be quite large in a Sea Scallop which allows it to “swim” across the ocean floor and not creep along like a clam does.

Personal Log 

Two days ago the weather was warm and sunny.  I was lucky enough to see whales. I have never seen a whale out of captivity before and it was beautiful to see.  This morning there were very heavy rains and lightning. It didn’t take long for that weather front to move on. I am tired as my body is still adjusting to the work schedule. The work is also very physical as much of what we are sampling ends up back in the ocean.  We are collecting, shoveling, measuring and cleaning all the time. A few more day and we’ll be back to port at Woods Hole.  I will be returning to finish teaching summer school on Monday.  I can’t wait to be in the classroom and see my students again.

Answer to last log: The picture was the internal structures of a scallop, a two-shelled mollusk. The black dots were eyes. I read that the eyes are fairly complex structures with retinas, lenses, and a large nerve fiber.

It’s a small world here on the ALBATROSS IV.  Chad Meckley is a 1996 Wilson High School graduate. Wilson is in Berks County and I live in Lancaster County, less than forty minutes away.  If you want to talk to Chad, look on the bridge.

Chad earned a geography/environmental science degree from Shippensburg University and moved to Colorado to be near the mountains.  After working several years in sales, Chad happened to be talking to a friend who knew about the NOAA Corps.  He applied, was accepted, and began training in February 2006.

We are on Leg 2 of the Sea Scallop Cruise and it is Chad’s third cruise with NOAA.  He enjoys being on the ocean and plans to continue his NOAA career.  Chad has two goals: to become Officer of the Deck (so he can command the ship) and to experience his first winter at sea.

It is evident that Chad enjoys what he’s doing; you can see it in his smile.  Best Wishes, Chad!

Last watch was not quite as busy as the night before.  We had two stations that were mostly Brittle Stars, very interesting little starfish.  They are a tannish color about the diameter of a coffee mug, with long thin arms that visibly move. When they were shoveled into laundry size baskets each time we had two baskets full, and that’s a lot of Brittle Stars!

Personal Log 

Yesterday, Sunday, was an absolutely, drop dead gorgeous day on the ocean.  The sun was out and the water was calm.  Whales were sighted, but in the distance.  I did see them surfacing and took pictures. Imagine a 4×6 all bluish-green and a fourth-inch dot of black. Sunset was working on spectacular, but just as the sun reached the water it went behind a layer of clouds. We are almost at full moon and the night time was just as beautiful in its own way.

Science and Technology Log 

Yesterday was quite a day—many stations, lots of scallops, and BIG rocks.  I am amazed that the trawl net liner was not damaged.  Last night, though, a rock the size of a small car was hauled onto deck—that one did tear the liner.  It’s interesting to watch the winch drop it in the ocean.

My new special position (I’m still sorting, shoveling, and measuring) is taking the inclinometer, or bottom contact sensor, reading.  To you landlubbers, it’s a device attached to the trawl that gathers data and tells the scientists whether the net was parallel to the bottom of the ocean. So when the net comes up with very little the information from the inclinometer is helpful.

Here’s what I do. I have an optic shuttle (about the size of a hot dog) that I secure in the inclinometer located on the trawl.  Each part has sensors and when put together properly the inclinometer sends the data to the optic shuttle (like a zip) and when all information is received and a little green light flashed I take in into a computer and transfer the data onto the hard drive. It’s an important piece to the mission.

What I have been doing here is an example of how important hands-on learning really is for understanding and transfer. I could have read all about this experience (like you are with this journal), but until I held the fish, scrubbed the scallops, cut into a Monk fish to discover the ovaries, etc., I had no real understanding.  Amazing!

The weather remains beautiful, the people are great, and the food is delicious.

Science and Technology Log 

If you are observant you will notice that I’m on my second Friday in a row.  Time is a hard thing to keep track of here on the ocean.  Last watch, Thursday I think, we entered Canadian waters. I was looking for a sign the said “Welcome to Canada”, but I must have missed it.

I am a scallop scrubber!  With each haul five scallops are chosen at random to gather in-depth data on (all other scallops are weighed and measured only).  The shells are scrubbed clean so the scientists on shore can determine the age.  Scallop shells are a little like a tree trunk. Age is determined by growth rings.  The larger scallops can be five years and older. The scallop is measured for length and weighed individually then opened. The sex is entered into the computer next.  Male scallops have a white gonad and females have a pink gonad.  The gonad is weighed, and then the muscle (what we would call the “scallop”) is cut out and weighed.  The shell is dried and numbered to match the data, bagged, and frozen.  Some scallops are very clean, but others can have barnacles, “weeds”, sponges, and/or slime (don’t know the scientific term!) growing on their shells. As a shell scrubber you get to know these things and the best way to remove them!!  Finally the whole station is hosed down for the next haul.

Personal Log 

The noise of the engines and the rocking of the ship are becoming second nature.  The weather has been kind and swells small.  I am really, really hoping that is stays this way.  Laundry is my goal for the morning.  The washer and drier are behind a metal door called a hatch. There are six dogs (big metal latches) that must be closed when the ship is at sea. I have opened and closed those six dogs so many times I’ve given them names: King, Lassie, Rin Tin Tin, Lady, Spot, and ToTo!  So many things to learn.
