The last three and a half days of the experience were the transit back to Kodiak. This gave me a lot of time up on the bridge and in the surveyors’ work areas.

So many things impressed me about the crew on this trip.  I think most of all, seeing that a group of young scientists between 22 and 38 (I believe) were ultimately responsible for all of the ship operations and were doing a phenomenal job! Fairweather has the largest number of junior officers on board and the atmosphere is of constant training. I kept thinking about the ages of most of the junior officers and how my own students could be in this position in a few years. The opportunity to grow as a member of a uniformed service and receive all of the training while still being able to pursue the sciences is incredible to me and I intend to make sure that my students know about the opportunity. I can’t tell you how many times I thought, “If I had just known this existed when I graduated college…”

 

On the long trip back, we were traveling through dense fog, narrow rocky passes in the middle of the night, and areas of high and sometimes unpredictable currents. We even managed a rendezvous with another NOAA vessel in order to pass of some medical supplies. Throughout all of it, I watched the NOAA Commissioned Corps officers handle everything with tremendous grace under pressure. But on Fairweather, I found out their work does not stop with the ship operations. Each of the officers are also directly involved with the hydrographic science, and have responsibility for a specific survey area.

The Survey team are also responsible for specific survey areas.

Drew & Bekah

Survey techs Bekah and Drew at their computers. If they’re not eating, sleeping, working out, or on a survey boat – this is probably what they’re doing!

For each area owner, this culminates in a final report (called a Division Report, or DR) giving details of the survey and talking through all anomalies. Survey work does not stop. These folks are working 7 days a week and often 14+ hour days when they are out at sea.

In some cases the owner of a survey area will have very intimate knowledge of a survey area because they had the opportunity to be out on the survey boats. But in many cases, this will not be true. Ultimately their responsibility is making absolutely certain that every piece of necessary information has been gathered and that the data is clean. I was told that in most cases, writing the final report will take a couple months.

These reports will eventually become mapped data that is accessible to anyone through the National Centers for Environmental Information (NCEI). But it will also be sent in various forms to be housed for shipping navigation and other industries.

Sleepy Surveyors

If you’re working long hours 7 days a week, you learn to take advantage of any opportunity you get to rest. A couple members of the survey team, catching a nap on the transit back from the Yukon Delta to Fairweather.

With all of the work they do at sea, ports can become very welcome places. The Fairweather crew had gone into port at Nome, Alaska several time through July and August and were excited to pull into Kodiak. Even on our transit south, I watched the crew get more excited as they left the desolation of the tundra and we began to see cliffs and trees again.

I am so glad that I saw the tundra finally, and that I will now be able to explain it more fully to my students, but I can also completely understand how the sheer vastness of the northern parts of Alaska could make you long for more varied terrain.

I only got to spend one day in Kodiak, but it is a breathtaking place. I didn’t get to do any serious hiking, but I did see the salmon running and ended up on an old nature trail. And the best part was that I got to see a bunch of amazing people relax and enjoy their time away from work.

Would I do this again if I had the opportunity? Unequivocally YES!! I would jump at the chance!

Would I recommend this to other teachers? Absolutely! It is an amazing experience. Granted, I think I had the best ship with the best crew…

Geographic Area of Cruise: Gulf of Mexico

Date: October 4, 2017

Science and Technology Log:

Well, I’m back on dry land, with lots of great memories of sharks, big and small, and all the interesting people who I spent two weeks with on the Oregon II.  And let’s not forget the red snappers either.

Cuban dogfish: The smallest species we caught

On our last day, we fished at a couple of sites right off the coast of Alabama and caught lots of sharks, plus a new species of grouper for the trip.  The scamp grouper (Mycteroperca phenax) is apparently not frequently found on the longlines along the coast of Texas but becomes more common along the coasts of Mississippi and Alabama and up the Eastern Atlantic coast as well.

The groupers are mostly protogynous, meaning that when they become sexually mature, they are always females.  Only later in life, when they have grown bigger (and have the right environmental influences), do they transition to males.  This species can live for more than 30 years, but that’s actually relatively short for a lot of the grouper species, some of which can live to 60 years or more. Scamp grouper come together in groups to reproduce, so this makes them vulnerable to overfishing.  The management councils take this into consideration when making a management plan and will close off areas known to be spawning grounds during the reproductive season.  These are also great areas to target as Marine Protected Areas.

All of this knowledge about the scamp grouper (and other species we encountered on this survey) was gained through careful scientific research.  As mentioned before, the long line survey was started in 1995 and has been conducted using the same methods every year since then.  These data are used by fisheries managers to set catch limits and detect changes that might indicate problems for the species living in these areas.  In other words, the science forms the basis for decision making and planning.

This is true for the various surveys that NOAA conducts in the Gulf each year.  The Groundfish Survey, for example, provides vital information about the extent of the Dead Zone off the coast of Louisiana, by measuring dissolved oxygen levels on the sea floor as part of the survey.  This data tells us that we need to continue to work on controlling nutrient inputs into the Mississippi River from agriculture lands and cities that span much of the eastern United States.  Scientific research also tells us that we need to be planning for and mitigating the effects of the looming problem of climate change.

Climate change will certainly bring about significant change to the Gulf.  As ocean temperatures rise, water becomes less dense and therefore takes up more space.  Along with continued melting of land-supported ice in the polar regions, this is contributing to a cumulative increase in sea level of 3.2 mm per year (https://oceanservice.noaa.gov/facts/sealevel.html).  In the Gulf, this increase will particularly impact estuarine ecosystems that are rich nurseries for many fish species and are extremely productive habitats.

One of the predictions of many climate models is that increased global temperatures are likely to bring about more frequent and more intense hurricanes.  This 2017 hurricane season is a stark reminder of the devastating impacts that hurricanes can have, even when we have the scientific tools to predict approximately where and when the storm will make landfall.

Finally, the increase in global temperatures will make the regions surrounding the Gulf less pleasant places for people to live.  The summers are already very hot and humid, and a degree or two hotter will make a lot of difference in the livability of the region.

We know all of this through careful scientific research, and there is a consensus amongst scientists that this is happening.  To prepare for the effects of climate change and to know how to best minimize those effects, we must continue to collect data and do science.  After all, what is the point of scientific research if we don’t use the results to make better choices and to address the problems that are facing us?

At the end of my time on the Oregon II

Personal Log:  I am so grateful for the opportunity to go on this research survey and for the Teacher at Sea program as a whole.  I strongly encourage any teacher thinking of applying to the program to do so.  Thanks to NOAA and everyone at the TAS office for all your help and support.
