Where in the world is Ms. Almasi and why on earth is she there?

AGH! There’s ocean all around me and I don’t know where I am!!  Well, sort of. I know I’m on the Pacific Ocean and that we’re heading south right now. Last night we spent the night around Heceta Bank, where we’d seen the humpback whales, so I believe by now we are probably south of Florence.

I want to introduce you to the projects on board, as well as a few of the scientists and ship’s crew. There are two types of projects on this trip: scientific and educational. Dr. Leigh Torres is the Principal Investigator (“The Boss”) for the science projects and Tracy Crews is the Principal Investigator for the educational research project.

Let’s start with the education research project, since that is why I’m here. Oregon Sea Grant and Oregon Coast STEM Hub secured funding to test the question of whether a unique, hands-on experience with “near peer mentors” stimulates enough interest for students to prevent them from dropping out of science in college. The teachers were invited to see if this kind of experience will help increase interest in STEM fields for both teachers and their students back at home. The “near peer mentors” term refers to the fact that we have several levels of academic students: high school students à undergraduate college studentsà graduate students à professor & high school teachers. This is also an opportunity to help grad students learn to communicate and teach others about their research.

OK, now for the Science research. We are out here primarily to collect data on the population abundance and behavior of marine mammals and pelagic birds. Pelagic means open ocean, so these are the birds that spend most of their lives on or above the ocean. Most of them raise their chicks on land, but that’s the only time we’ll see them on land. Except for those pesky and abundant gull species.


Ms. Almasi and Etasha work on the CTD

There are four scientists on board, if you don’t count Tracy, the high school teachers, or the high school students. As I mentioned before, the Principal Investigator is Dr. Leigh Torres, whose expertise and research area is marine mammal ecology (especially the distribution, abundance, and behavior). She has two graduate students on this cruise who are working on their Master of Science degrees: Amanda and Florence. Jane is another grad student who works with Dr. Rob Suryan on the ecology of pelagic birds, such as albatross, shearwaters, storm petrels, and fulmars. Amanda studies harbor porpoises and Florence works on the feeding ecology of gray whales. On this cruise, Florence is managing the data from a large, heavy contraption called the CTD.

The CTD collects data that is useful for a wide variety of projects.  CTD stands for Conductivity, Temperature, and Depth. A very heavy piece of equipment, the CTD has sensors for conductivity, temperature, elevation (an altimeter), pressure (helps measure depth), and a GPS. There are also about 12 water chambers for collecting water samples. Here’s one of the coolest parts – Florence and/or the ship’s Marine Technician, Croy, can program the sample collection from the Tech Lab. So they tell the CTD from the computer to close these chambers at different depths – and they can read what depth the CTD is at from the graphs generated on the computers. Once the CTD is pulled back up to the surface, the chambers are opened and water is removed and tested.

Why do they need the conductivity measurement? Turns out that electrical conductivity is determined by ions in the water. Many ions are salts, so the more ions in the water, the greater the conductivity, and the higher the salinity (salt content). This feature – salinity and/or conductivity – determines which species of organism can survive in the water. Pretty cool, huh?

So far the CTD has been deployed 4 times on this journey – and right now it’s about lunch time on Wednesday.  Our deepest spot will occur tomorrow when we head north to the Columbia river.

P.S. The Styrofoam cups and plastic bottles and containers just went down with the CTD and will be reaching a depth of 1,400 meters. This

Coming soon: spotlight on the researchers!

Also, if you are interested in having me interview someone on board about a particular career, please let me know. There are 25 of us on board – 13 students, teachers, and scientists plus 12 ship crewmen and women.  More soon!


Of Whale Poop and Shearwaters

Wifi is spotty and I didn’t have down time yesterday, so this morning I’m posting a short note I wrote last night. I have pictures, but with the wifi, I can’t connect them yet.

Did you know that Blue whale poop is RED?!


We did NOT see blue whales and their feces today, but we did have the once-in-a-lifetime (at least for me) experience of sitting next to a pod of more than 50 humpback whales, watching them feed.  Pink-footed shearwaters (with a few sooty shearwaters thrown in) loved the whales too; there must have been more than 200 shearwaters feeding on the krill and other plankton brought up by the whales.


Humpbacks, Gray whales, and blue whales belong to a group called the Balinadae, because they have a structure called baleen that helps them sift prey items. Watching them feed is incredibly – they drive their tiny plankton prey upward and into their mouths by starting below them. From the boat, we see their huge, open mouths swoop up and out of the water, then they turn their bodies sideways while sifting the water out and keeping the plankton in. Even our Chief Scientist, Dr. Leigh Torres, was astounded at the size and feeding behavior of these creatures. We collected a plankton sample at the same time and found krill! Krill are actually what makes the poop of blue whales (and probably other baleen whales) red because these little shrimp relatives are pink.


Just before that we saw the humpbacks, we spotted a small group of killer whales – about 4. Wow, incredible day.

“Chunking” takes on a whole new meaning…or…What REALLY causes motion sickness?

On September 13th I will board the Oceanus, the research vessel of Oregon State University. I feel honored to join this cruise, along with two other teachers and four high school seniors from up and down the Oregon Coast. (One of the students is the son of our own Mr. Wood – how cool!) While on the 3-day cruise, I will try to write daily blogs about the research we are conducting; then on Friday and Saturday of that week we will be helping OSU in Portland with tours of the ship and other educational ventures.

I’ve never spent this long on a ship (well, except for that time on the Alaska ferry a couple years ago) and I’m a little afraid I might get seasick. OK, I’ll be honest – I’m a lot afraid.  Once I did a day trip to see pelagic birds (they live mostly out on or above the open ocean) and I felt horrible the whole time.  Rumor has it (Kraft, 2015) that ⅓ of people on a boat or ship get sick with even just a little motion, but ⅔ of us get sick with heavy motion (whatever THAT means – isn’t it a matter of perspective?). Anyway, just in case I *do* get seasick, I decided to write a blog post about the science of motion sickness. I’m sure I won’t want to write about being seasick while I’m actually seasick (UGH! Imagine describing how you feel when you’re hugging the toilet!), so I’m doing this ahead of time. Even as I write I feel a little nauseous. Hmm.

To start off, I decided to look up slang phrases that describe how I might feel or what I might do if I get seasick. I found these colorful terms or phrases on Urban Dictionary.

The obvious synonyms:

  • Puke
  • Hurl
  • Barf
  • Upchuck

More colorful phrases:

  • Pray to the porcelain god
  • Toss a sidewalk pizza
  • Tango with the toilet
  • Make modern art in the toilet
  • Have a technicolor yawn
  • Revisit your breakfast
  • Vomit your victuals
  • Perform peristaltic pyrotechnics
  • Paint the town red… and green and orange and pink

These are my two favorites (today):

  1. Become a multicolored organic fountain
  2. Drive the porcelain bus

I tried to find a good picture of a real multicolored fountain, but I came across this picture of the fountain at the Seattle Center, and I used to LOVE going to this fountain when I was a kid, so I’m showing it instead of a multicolored fountain. This is because it’s my blog, and even though I’m trying to make it seriously about science, I keep getting distracted by fun stuff.

OK, but let’s get serious.  What actually causes this horrible affliction of Motion Sickness? This need to drive the porcelain bus? I’ve always heard that motion sickness is caused by your inner ears, but since I do teach Anatomy & Physiology, I really should try to understand exactly WHY this happens and WHAT it means.

 ear_anatomy_4*Photo from http://www.carolinaear.com/patient_resources/patient_education.shtml.

The ear is an amazing organ of the Nervous System. It’s pretty complex, so I can see why it would be nervous. Notice the nerves attached to the inner ear: the Vestibular nerve, Facial nerve, and Cochlear nerve (also called the Auditory nerve). The inner ear itself lies within the temporal bone (looks like spongy bone, for any of my A & P students reading this) and consists of the Cochlea and the Semicircular canals.

The brain senses motion from three sources in our bodies: the nerves of the ears, of the eyes, and proprioceptors, which are receptors found in muscles, joints, and their surrounding tissues (Medical Dictionary, 2016). The sensing of motion relies on all three inputs, but to different degrees. For example, if there is no input from the ears, motion sickness will not develop; likewise, visual input appears to be less important for the brain to sense motion than do the other two sources (Kraft, 2015). To send impulses to the brain, neurotransmitters (chemical messengers) are released by neurons (nerve cells); these neurotransmitters move either to an adjacent neuron or muscle cell, depending on the type of neuron and neurotransmitter that are involved in the message.

According to Kraft (2015), three neurotransmitters are involved in the sensing of motion by the brain: histamine, acetylcholine, and norepinephrine. Note that these neurotransmitters have other functions, as well, but that’s a whole ‘nother blog post. I always wondered why people take antihistamines for motion sickness — these drugs prevent the release of the neurotransmitter histamine, so your body does not attack allergens, which is the cause of allergies (yep, another blog post subject). I’d always thought antihistamines were just to treat allergy symptoms, so the practice of taking them for motion sickness didn’t make  sense to me, but now I know why! Pretty cool!

But I digress. The reason I brought up the neurotransmitters was to explain the sensations of motion sickness. These neurotransmitters are released from different types of neurons to tell your brain you are moving. Your brain takes complex information from three different sources and puts it all together to let you know you are, in fact, in motion. When the motion is caused by YOU – you’re swimming, riding your bicycle, or hiking to find a geocache, the brain handles the three conflicting inputs well. The problem arises when your body is not causing the motion: being in a vehicle, for example. When you are in a car, airplane, or on a ship, your brain is not coordinating the movements of your body. This messes with the balance of the neurotransmitters involved in motion. Thus medicines to treat motion sickness usually target the control and balance of the three neurotransmitters.

I think I’ll end this post here, as I really don’t want to discuss the symptoms of motion sickness. Thanks for reading and until next time!
