Science and Technology Log:

When one hears that there is an ET aboard NOAA Ship Oregon II, they might imagine E.T., the extra terrestrial, wearing a sailor hat and driving the boat.  Fortunately for everyone aboard, E.T. is not driving the boat and the ET aboard the Oregon II is Lester S. Andreasen.  Lester, known as Les, is a rotational Electronic Technician (ET).  Les is responsible for the network and communication while out at sea.  He also provides support to the NOAA scientists by assisting them in maintaining shipboard scientific data collection.

Les Andreason, Electronics Technician

Prior to his career aboard NOAA Ship Oregon II, Les was in the Navy for 23 years.  His first station right out of boot camp was Key West, FL.  That is where he learned about navigational radar, and preformed corrective and preventative maintenance on electronics on the unique squadron of Patrol Hydrofoil Missiles (PHMs).  Les started in the Navy as an electronic technician seaman (E3), and worked his way to a command master chief (E9).  When he left the Navy he began his career aboard dynamic positioning ships.  When the oil field began to struggle, Les was hired by NOAA.

Les describes NOAA Ship Oregon II as a “fun ship”, as he really enjoys the people.  He finds it fascinating to see how the crew interacts with the scientists while completing the shark surveys.  Les’s advice to anyone who wants to pursue a career as an ET would be to study computer science, mathematics, or computer engineering.  I guess he is a little like E.T. the extra terrestrial, because without Les we wouldn’t be able to ‘Phone Home’ and talk to our families or anyone on shore.

Personal Log:

We have been cruising for two days now, and won’t start fishing until tonight.  Since I have had some extra time on my hands, I got to try out the nifty workout equipment.  I did a circuit of 2 minutes on the bike, 20 kettle bell swings, and 10 dumbbell squats.  I completed 10 rounds.  Then I proceeded to the stern where I did planks, sit-ups, and stretched.  It was very relaxing to be able to look out over the water.  I didn’t even feel like I was working out because it was so peaceful.

abandon ship
This is what I will be wearing in case an emergency situation occurs and I have to abandon NOAA Ship Oregon II.

 

We also ran ship drills so everyone is prepared on where to go in an emergency situation.  Aboard any ship, safety is the number one goal.  I feel more comfortable knowing that I will have a suit and life jacket on if I need to abandon the ship.

 

 

 

 

 

 

 

 

Did You Know?:

The NOAA fishermen stated that they have seen killer whales (Orcinus orca) in the Gulf of Mexico.  Normally this species is found in colder water, but according the NOAA Marine Mammal Stock Assessment Report (2012) there were approximately 28 killer whales reported in the Gulf of Mexico in 2009.

Animals seen:

Royal Tern (Thalasseus maximus)

Flying Fish (Exocoetus peruvianus)

Science and Technology Log

Today, John Pohl, one of the fish biologists showed me the VPR (video plankton recorder). The camera is attached to the CTD (Conductivity, Temperature, and Depth), which is operated by Steve Pierce, a physical oceanographer, and Phil White, chief survey technician, who work the night shift. The CTD is a large apparatus which has room for many additional sensors and attachments. The CTD onboard the Miller Freeman has a dissolved oxygen sensor in addition to the VPR.

Each night Steve sends the CTD down to the seafloor (about 7 times) to collect data. He is most interested in determining the differing densities of water at different depths (depth is based on pressure, which the CTD measures). He then calculates the densities using conductivity and temperature. By measuring conductivity (how easily electric currents pass through the water sample being tested), Steve can get a measurement of that water sample’s salinity.  Density of water is then calculated from measurements of salinity, and temperature. An equation is used which relates the measurements so that density can be found if these other two values are known. Steve records all the data each night, and will use this information to study currents and their movements.

The VPR is a camera which records video as well as still pictures as it descends to the sea floor. The data are recorded, then uploaded to an external hard drive. The file is very large, as it takes about ten minutes to transfer all the data. The pictures and video will be used by biologists (not on board presently) to identify and determine the percentage of plankton (plankton consist of any drifting organisms) floating throughout the water column. Each time before we set out the fish nets, two people go to the bridge to look for marine mammals. If any are present the nets won’t be put into the water. A few tows have been cancelled due to the presence of marine mammals. This is a great step in keeping them safe. It is always special when I see dolphins or whales.

The only fish tow of the day (no marine mammals present) consisted of mainly Humboldt Squid and some Pacific Hake. Today we used a load cell to get a total mass; this is a device which hooks up to the net and crane. The load cell gives a mass of the entire haul. The majority of the load was released back into the water while a smaller sample was retained. The weights of the Hake and squid were then determined using bins and a balance. The scientists can use the subsample data to determine the data for the entire load.  Bycatch, defined as living creatures that are caught unintentionally by fishing gear, are occasionally found in the net. Today a rougheye rockfish was caught, and yesterday a sleeper shark were accidently caught. The scientists do a very good job of limiting bycatch using their acoustic data.

Personal Log 

A rougheye rockfish – what a pretty fish
A rougheye rockfish – what a pretty fish

I am enjoying the long hours of work, and have gotten into quite a rhythm. I also enjoy spending time with the hardworking and intelligent staff here on board. We work together as a team, and everyone enjoys their jobs. NOAA has chosen a great group of officers who set a very positive tone and make the ship a great workplace. I would love to take a sabbatical from teaching and work on a NOAA ship. I’m having a lot of fun and learning a bunch. I will take back a lot of positive experience to share with my students, family, and friends.

I have also learned to appreciate the smells of a load of fish. As we move the fish from the holding cell, to small baskets for weighing we are constantly splashed in the arms, face, mouth, eyes, etc. I find it pretty amusing every time I get splashed, or even better, when I splash John, Melanie, or Jake. It never grows old. The hardest portion of my day is determining what movie to watch while running on the treadmill (I finally mastered the art of the treadmill on a rocking boat and can leave the elliptical trainer alone). The boat has close to 800 movies to choose from.

Animals Seen Today 
Pacific White-Sided Dolphins, Rougheye rockfish, Humboldt Squid, Pacific Hake, Albatross, Sheerwaters, and Murres.

Poem of the Day 
Squid ink, squid ink!
O! How you make me stink!
You stain my face, you stain my clothes;
I must wash you off with a fire hose!

You make me scratch, you make me itch,
You even turn Melanie into a wicked witch!
(which is a horribly difficult thing to do—
She’s as gentle as a lamb in a petting zoo!)

Why not John, allergic to your ink!
Torment HIM with your venomous stink!
But no–not ME! All I want are Hake.
So torment instead “almost” graduate Jake!

But once again, though our dinner hour,
Because of you I must shower!

So I beg you, O squid, to hear my plea:
In the future, stay away from me!
Does that sound good?
Do we have a deal?
If not, well then—you’re my next meal.
