First, A blog-reader texted me to say that it looked like I was having fun! Yes, while NOTHING could be more fun than your birthday party, Teacher-At-Sea is at the top of the list of fun teacher-things to do! I hope that ALL teachers, especially those from North Carolina, will apply to be a NOAA Teacher at Sea as we continue to grow strong STEM ecosystems while helping our communities make informed decisions.  Thanks for reading Elaine!

Second, an answer to last BLOG’s math problem: If 1 knot = 1.15 mph, and the ship is traveling 8 knots, a stop 15 miles away will take us a little over 1 and a half hours (about 1.6 hours) to reach.

Science at Sea

Animal monitoring is an active part of our floating weather station. A dolphin sighting texted through WhatsApp brings lots of off duty folks up to see. The NOAA Corps on the bridge keep a constant vigil to make sure we don’t hit a whale. But the “Seabird and Marine Mammal Observers” are a functional part of our Science team. They spend their daylight hours on the Flying Bridge scanning the horizon and recording their findings. The species, group size, and photos are catalogued and stored for long term monitoring. This data can be used to estimate bird and mammal abundance in the Northwest Atlantic Ocean now as well as set baseline data through AMAPPS (Atlantic Marine Assessment Program for Protected Species). NOAA Scientists are conducting surveys and developing abundance and distribution models to better understand how protected species such as whales, dolphins, and sea turtles use our waters.

Career Spotlight

Cameron Cox has been able to turn his love of birdwatching into a career. As a Seabird and Marine Mammal Observer Scientist on NOAA Ship Pisces, he can be found on the Flying Bridge during the daylight hours.

Cameron’s passion for birding kinda snuck up on him. He remembers hiking with a neighborhood friend who had started birdwatching for a hobby. At age 13, Cameron was hooked. Since he was homeschooled, Cameron was able to carve out time to pursue this new interest. He spent his 20’s traveling around the United States looking at birds. He had a 2-thousand-dollar car and 6-thousand dollars worth of optics – binoculars, camera, and spotting scope.  

Cameron explained to me that the long term monitoring projects are hard for Universities and non government organization (NGOs) to fund, which is why our NOAA work is so valuable. The data sets are free and readily available to everyone. Unfortunately, when the BP Deepwater Horizon oil spill decimated the Gulf Coast, there wasn’t baseline data available for recovery and accountability. He was able to assist in creating possible baseline data by performing Seabird and Marine Observations off the coast of Florida, a similar ecosystem.

These days, Cameron leads birdwatching tours in what he calls “Environmental Entertainment.” He loves watching others connect with the importance of the natural world, and hopes to help them become conservationists. Cameron has also published two books, Terns of North American: a Photographic Guide, and a Peterson Reference Guide to Seawatching: Eastern Waterbirds in Flight, co-written with Ken Behrens. Writing at the rate of one book a decade, his ongoing projects will ensure he has a long life! This is Cameron’s first time being a Seabird and Marine Mammal observer with NOAA. We hope it is not his last!

Interesting Things: The Seabird and Marine Mammal Scientist Observers onboard are monitoring lots of animals specifically, but there are other animals we are studying or just find in our nets.

Engineer Drew found this crab in our sea strainers (they strain the water used around the engines). ET Alex named her Crustacina (spelt like crustacean, but pronounced like Cristina). We will keep her on-board until we can get to more shallow waters for release.

NOAA Scientists are collaborating with a group in Miami to study ocean acidification on pteropods’ shells. The phronima amphipod (see video below) inspired the movie alien. They commandeer a salp, eat the flesh, and then lay eggs in the empty pouch.

Personal Log

Have you heard of or participated in the Christmas Bird Count (CBC)? Started in 1900 by 27 dedicated birders, this GOAT Citizen Science Project provides long term data sets that help conservation biologists of all forms study long term bird health and guide conservation actions. The CBC is one example of how good can win (Side Hunt, no link will be provided). Consider joining a Christmas Bird Count this year to learn more about Citizen Science and the importance of long term data sets (see CBC ).

You do the Math: The First Christmas Bird Count was held December 25, 1900. If 18,500 individual birds representing 89 different species were logged by the 27 participants, how many different birds were seen (on average) by each person? Check in the next blog post for the answer.

These styrofoam birdies are going to be a science experiment of their own…. stay tuned!

  1. What will you miss most when you are finished with your time onboard? Do you have WiFi? If not, has it been difficult to live without? Are you hopeful for the future of our oceans after seeing all the work that is done?

  2. I will definitely miss the fabulous people who have patiently taught me the science of ecosystem monitoring! The entire team works so well together, it makes my heart happy, and in that way hopeful, to see “science” be taken so seriously!

    I’m also going to miss the coffee maker that steams the milk.

    And yes…. I have WiFi.
