Science and Technology Log

Catching fish in hard bottom habitats is not without its risks. Sometimes, the traps can get caught on a ledge and the rope breaks when the ship tries to pull up the trap. This is what happened on Wednesday. When a trap is lost and stays in the water, it is sometimes called a “ghost trap.”

The first thing I thought about was the fish that were stuck in the trap. Oh no, how will they get out? The good news is that the trap was creatively designed. It has an escape door that is held shut by zinc clips. Zinc is a type of metal that deteriorates in salt water. In a few days, the zinc clip will break and the door will open so the fish can get in and out of the trap. Hooray for whomever thought of that design!

 

This clip is designed to deteriorate in salt water. It will break apart in a few days and an escape door will open so that fish may freely move in and out of the trap.

The second thing that I thought about was the two cameras. It would be sad if we could not use them again for future surveys. And, there could be some interesting observations to be made from the video footage.

 What Are The Next Steps?

The purpose of our mission was to collect data about fish populations for fish species that are important to humans, including grouper. Currently, there are limits in place for how many grouper can be caught each year.   These limits are in place so that there are grouper for future generations to enjoy.

We now have a lot of data from deploying over 200 traps, with each trap having video footage from two cameras. We caught 54 groupers. They included red grouper, scamp, gag, rock hind, and graysby.  In a quick glance at the video footage, we saw many grouper that decided not to go into the trap. It will take a lot of time to review all the video footage. But after all the video footage is analyzed and the MeanCount is determined, what happens next?

Take the poll below and vote on what type of grouper is in the middle of this photo.

The next step is for our data to be added to the other data from all the other Southeast Fishery- Independent Survey cruises. Scientists will look at this data, along with other data from commercial fishermen, and make some conclusions about what they think is happening to the populations of these fish.

Based on these findings, policymakers will decide whether the current limits should be changed or stay in place.

In the end, the goal of everyone should be the same: making sure that groupers are here for a long, long time so future generations of people can enjoy them.

Personal Log

I have gotten used to life on a ship. Some things are harder to do, like exercising. Have you ever tried to run on a treadmill on a ship while it is rocking back and forth and side to side?   I was never very good at running on a treadmill on land. It is twice as hard when you are at sea.

The food has been fabulous. We eat meals three times a day.   We eat a lot of good fish, like fried grouper and fish tacos. Some of my non-fish favorites have been flank steak, barbeque chicken, pizza, meatball subs, and black bean burgers. And, no matter how rough the boat is rocking, I am still able to get to the dessert table for cookies, or ice cream, or cupcakes, even if my path is not a straight one.

 

This is a photo of the "galley." It is the name of the place on board where we eat our meals.
This is a where we eat on the Pisces.

We have been lucky with the weather too. We have only had one day where it rained most of the day. The waves have only been in the 4-6 foot range during the rough times.

I feel very fortunate to have been chosen to be a NOAA Teacher at Sea. I have learned so much about fishery research and ocean floor mapping. I am happy to have played a small role in collecting this important data.   I can’t wait to share this knowledge with my students.

I can’t thank enough Nate Bacheler and the other scientists on board for letting me share this adventure with them. I would also like to thank the crew of the Pisces. They were very knowledgeable and helpful.   I hope our paths cross again. Goodbye Pisces.

You may be wondering about the trap that we lost.  I have good news.  Ensigns Jim Europe and Hollis Johnson saved the day.  They are NOAA divers.  They are also part of the NOAA Corps-one of the seven uniformed services of the U.S. and the officers that drive the ship. They retrieved the lost trap and the cameras very carefully.  Great job, Jim and Hollis!  You can learn more about the NOAA Corps here:http://www.noaacorps.noaa.gov/

Did you know?

The ocean and humans are inextricably interconnected.

Can you think of a few ways that the ocean affects humans? Can you think of a few ways that humans affect the ocean?

Personal Log

Hi, my name is Kevin McMahon. I am a sixth grade science teacher at Renfroe Middle School in Decatur, Georgia.  I am excited to be a part of the 2014 Teacher at Sea program.

Ever since I was a kid, I have been fascinated with the ocean.  I spent many summers in Ocean City, Maryland.  I loved watching blue crabs and horseshoe crabs scurry across the bottom of the bay. I loved skimboarding on the thin film of water left behind by a retreating wave. And, I was amazed at how rough the surf could become when a storm was heading toward us.

My favorite shows on T.V. also had water themes.  Marine Boy was a cartoon about a boy who could stay underwater and breathe by chewing a special gum.  How cool is that? I also liked The Undersea World of Jacques Cousteau.  He was one of the first people to take a camera underwater and share his discoveries of life under the sea.

I recently celebrated my birthday.  My daughter Becky made me a birthday cake shaped like the earth. The cake has four layers to match the four layers of the earth. If you look closely, you might be able to see a picture of the NOAA ship, Pisces, in the Atlantic Ocean.  The Pisces is the research vessel that will be my home for two weeks. Thank you, Becky!

I won’t tell you how old I am, but I will give you this hint.  I have travelled around the sun 50 times since I was born!  How many times have you revolved around the sun?

In a few weeks I will have the opportunity to learn more about the ocean and share it with you.  I will be helping Nate Bacheler, a scientist with NOAA (the National Oceanic and Atmospheric Administration), collect data on important fish species in the Atlantic Ocean, like snapper and grouper.

Why are these fish “important”?  These fish are fish that humans like to catch and eat.  Part of our mission is to learn about the health of these fish populations and to learn whether or not they are being overfished.  If people catch too many of them, there might not be enough of these fish to help feed humans in the future.

Our ship will be leaving from Morehead City, North Carolina.  As a college student, I spent a summer near Morehead City taking a marine biology class at Duke University’s marine lab in Beaufort, NC.  I have fond memories of my time on the coast of North Carolina and am looking forward to seeing how it has changed since I was there.

The next time that I write, I will be in the Atlantic Ocean. I am looking forward to sharing the science with you and sharing what I learn about the teamwork involved in making this scientific expedition safe and successful.

 

Kristy Weaver: Ms. Weaver Goes to Sea


NOAA Teacher at Sea
Kristy Weaver
Aboard R/V Savannah
May 23 – 31, 2012

Hello from Hillside, New Jersey! First, for any out-of-state readers, allow me to say that despite what you may have seen on “reality” television about this beautiful state, we do not all tease our hair and have VIP memberships to tanning salons.  (Okay, so I may tease it a little, but only for special occasions!  Yes, this is my attempt at humor; bear with me.)  All kidding aside,  thank you for visiting.  I am excited to tell you about the NOAA Teacher at Sea Program!

Perhaps I should introduce myself before I start making corny jokes.  I am Kristy Weaver and I am happy to say I have been a first grade teacher here at The A. P. Morris Early Childhood Center for the past 12 years.  Our building is home to every pre-k, kindergarten, and first grade classroom in the district, and we  are currently a community of 668 students.

Hillside is part of the Partnership for Systemic Change which is a collaboration between the Merck Institute for Science Education (MISE) and six other urban or semi-urban school districts.  Through this partnership I have been a part of the Academy for Leadership in Science Instruction, which is an intensive staff development series that takes place over the course of three years.  I have also been a Peer Teacher Workshop facilitator and have had the opportunity to discuss effective science instruction at length with my fellow science teachers and professionals from MISE and partner districts.

Here is a little video trailer my class helped make to tell everyone about my trip.  See if you can spot the cameo appearance from our beloved class pet, Jerry.  My students had the responsibility of casting him in this role and are all super excited that Jerry will now be “famous.”

The purpose of the NOAA Teacher at Sea program is to provide teachers with real life experiences with scientific research and for us to then share that knowledge with the community upon our return.  This will strengthen my own content knowledge and expose our students to scientific research and science careers while increasing environmental awareness.  I am passionate about the pedagogy behind effective science instruction and while I hope that this experience will be shared with many classes, it will definitely be utilized to its fullest potential in my district.  This opportunity already inspired an impromptu math lesson when I showed my class my ship,  the R/V Savannah.  In order to grasp how big the 92 foot vessel is, we used 60 inch measuring tapes and counted by fives until we got to 90 feet.  Then we estimated two feet to help us get a sense of the size of the R/V Savannah.

This is my class, 92 feet down the hall! Wow! The R/V Savannah is larger than we thought!

I love being a teacher, and it is definitely where my passion lies.   However,  when I was a child I never  felt that being a scientist was an option for me because I didn’t know where to begin.  I had an innate curiosity about the water, but didn’t know that I could have built a career around it.   It’s my job to make sure that my students are afforded every opportunity, know that their dreams are within their reach,  and feel as if the world is at their fingertips- because it is!

How Did I Hear About Teacher at Sea?

Two years ago I attended the National Science Teachers Association Convention in Philadelphia, PA.  One of the booths at the exhibition center was for NOAA‘s (National Oceanic and Atmospheric Administration) Teacher at Sea Program.  It was fascinating to talk with teachers who had gone out to sea with NOAA in the past, and I immediately knew it was something I would pursue.  My whole life I had lived vicariously through scientists on various nature shows, and I was thrilled to learn that I even had the possibility to experience something like this first hand.

What the Research Says

So how is this going to help first graders?  In 2011 Microsoft Corp. commissioned two national surveys with Harris Interactive for parent and student opinions on how to motivate the next generation of STEM (Science, Technology, Engineering and Mathematics) professionals.

For most, the decision to study STEM started before college.

  • Nearly four in five STEM college students said they decided to study STEM in high school or earlier (78 percent). One in five (21 percent) decided in middle school or earlier.
  • More than half (57 percent) of STEM college students said that before going to college, a teacher or class got them interested in STEM.

This gives me, a first grade teacher, the opportunity to plant the seed early and expose children to STEM careers before they even reach the second grade.  If I can motivate just one child with this experience, or prove to them that they too should chase their dreams, then any amount of seasickness will be worthwhile.

Speaking of Motivation…Here is Mine:

I have always been fascinated by the ocean and how something could be equally tranquil and ferocious.  As a child I never “sat still” and my boundless energy had me bouncing from one activity to the next with less than a heart beat in-between.  Yet, even as early as three years old, I can remember sitting on my grandfather’s lap in Long Beach Island and just staring out at the water for what seemed like hours.  In retrospect it may have only been 15 minutes, but regardless, just looking at the ocean had me calm, captivated, and thoroughly entertained in the silence of my own thoughts.

Feeding Sea Turtles at the Camden Aquarium

When I was young I always loved the underwater pieces in my parents’ National Geographic magazines, but it never crossed my mind that I could someday be a diver.  When I grew up a little I decided that it was something I would definitely do “someday.”  I finally realized that someday never comes unless you make your “someday” today.  I became a certified diver three years ago, and up until this point, it is one of the best things I have ever done.  As an adult, I have always watched nature shows, but never in my wildest dreams did I believe that I would someday have the opportunity to experience something like Teacher at Sea.  I think this helps send an important message to my students: You should always  go out and experience everything you want in life.  I did a shipwreck dive to 109 feet, have fed sea turtles, swam with sharks, flew a helicopter, , and have been on a trapeze in two different countries.  Yet somehow, I have a feeling that all of these things will pale in comparison to the adventure I am about to have.

So What’s Next?

I am getting ready to head out to sea and my students and I are so excited.  The next time I write I will most likely be somewhere near Savannah, GA where I will be setting sail on the R/V Savannah for an 8 day reef fish survey.  While the first grade students are my target audience for my blogs while I am at sea, I encourage people of all ages to follow me along my journey.  I hope that everyone will be able to get something out of it, and that secondary teachers will be able to use this experience as a starting point for some of their lessons as well.

Please feel free to post your comments or questions, and I will do my best to bring back the information you are most curious about!
