Mission:
Microbial Stowaways: Exploring Shipwreck Microbiomes in the deep Gulf of Mexico

Geographic Area: Gulf of Mexico

Date: June 13, 2019

Introduction

In just two weeks I will be shipping out of Gulfport, Mississippi on the University of Southern Mississippi Research Vessel Point Sur.  As a NOAA Teacher at Sea, I will actually be a student again, learning all I can about ocean archaeology and deep-sea microbial biomes. I feel very lucky to have this opportunity to learn what it is like to live and work at sea! In particular, I am looking forward to seeing how archaeologists work at sea.  My undergraduate degree was in archaeology and I worked in the desert of New Mexico and southern Colorado where we mapped with pencil and paper, and took samples with a shovel. Ocean archaeology will require more sophisticated technology and a different approach!  

Let me give you a little background about myself.  My husband and I live in a tiny town called Husum on the White Salmon River in Washington State. My family enjoys outdoor activities including rafting and kayaking. This year my daughter is working as a raft guide on the White Salmon. I know when the commercial raft trips are passing by because I can hear the tourists scream as their boats go over Husum Falls!   My son is studying Engineering in college and is spending this summer in Spain learning Spanish and surfing. Unfortunately for my husband, summer is the busy time for construction. As a general contractor, he will be working hard.

During the regular school year, I teach fourth grade math and science at the local intermediate school.  One of our biggest science units each year is to raise salmon in the classroom and learn about the salmon life cycle, adaptations and the importance of protecting salmon habitat.  In addition, this year we tackled a big project around plastic pollution in the oceans and how we can make a difference in our own community through education and action. My students are rightfully indignant about the condition of our oceans, and I have also become an ocean advocate since initiating this project.

Student salmon drawings
Kids made scientific drawings of salmon, and then painted and stuffed them. They swam around the classroom ceiling all year!

Scientists on the Point Sur have several goals. First of all, they will map two shipwrecks that have never been explored.  Both are wooden-hulled historic shipwrecks that were identified during geophysical surveys related to oil and gas exploration.  Archaeologists hope to determine how old the ships are, what their purpose was, and their nationality, to determine if they are eligible for listing on the National Register of Historic Places (NRHP).   A third shipwreck we will visit is a steel-hulled, former luxury steam yacht that sank in 1944. It was previously mapped and some experiments were left there in 2014 which we will recover.

In addition to mapping, we will take samples of the sediments around the ships to see how shipwrecks shape the microbial environment.  The Gulf of Mexico is a perfect place for this work because it is rich in shipwrecks. Shipwrecks create unique reef habitats that are attractive to organisms both large and small. I wonder what kinds of sea life we will discover living around the shipwrecks we visit?

The first question my students asked me was if I was going to scuba dive. While that would be exciting, it’s not allowed for Teachers at Sea! To gather information about the shipwrecks, we will deploy a remotely operated vehicle (ROV) called Odysseus (Pelagic Research Services, Inc.) . Odysseus will have a camera, a manipulator arm to gather samples, a tray to carry all the sampling gear and SONAR and lights. I think I will be content to watch its progress on the ship’s video screens.

School is almost out, and my fourth graders are chomping at the bit to get out if the classroom and begin their own summer adventures, but I hope they will follow my blog and keep me company while I am on board ship!    Am I feeling a little intimidated? Absolutely! But also very excited to have the opportunity to participate in what is sure to be a great adventure.

Science and Technology Log

We have not started fishing yet because we are heading to our first transect off the western coast of the Haida Gwaii archipelago. I thought this would be a perfect time to introduce another research project that is gathering data on the Shimada. One of my roommates, Lynne Scamman, is on-board researching Hazardous Algal Blooms (HABs).

  1. What are Hazardous Algal Blooms?

They are large numbers of phytoplankton, either diatoms or dinoflagellates, who produce toxins. Phytoplankton are essential to the ecosystem because they produce half of the global oxygen. However under certain circumstances these organisms reproduce rapidly, skyrocketing the population, this is a bloom. Some of these phytoplankton produce toxins. When the populations are low the toxins aren’t a big deal. However, when a bloom of phytoplankton that produce toxins occurs there can be health concerns for organisms exposed to the toxins. We have to consider the marine food chain and something called bioaccumulation. Phytoplankton along with zooplankton create the base of the marine food web. Organisms who eat toxin producing phytoplankton retain the toxin in their body. Then any organism who eats them will also hold that toxin. You can see how the toxin would accumulate along the food chain and potentially hold serious side effects for organisms with high levels of toxin.

  1. Why is research being done on HABs?

HABs are becoming a problem for humans along the coasts and in the Great Lakes. Basically all of the factors that contribute to the increase in HABs are a product of human impact. Global climate change, increased nutrient pollution and global sea trade are all factors contributing to the rise in Hazardous Algal Blooms. We want to monitor so that eventually we will be able to predict when, where and why the HABs will occur.

  1. Why are YOU studying HABs?

One day I walked into my college biology lab and met a guest instructor who specializes in all things phytoplankton related. I was blown away by the complexity that some of these single celled organisms held. The professor shared a few species names and I started investigating. The species that grabbed my attention is called Nematadinium armatum. This organism has a rudimentary eye called a melanosome and nematocysts for hunting, again this is pretty impressive for an organism made of one cell. Once I learned about the variety in this microscopic world and how influential they were to the health of the entire ocean, I knew that I wanted to learn more.

Personal Log

I am still figuratively pinching myself every few hours at just how amazing this experience is to participate in first hand. Yesterday we left the dock of Port Angeles at 10am and the boat hasn’t slowed down since. We did drills to ensure that all aboard knew where to go in case of fire and if we needed to abandon ship. Part of the abandon ship drill is to make sure that everyone has and can get into their Immersion Suit aka “Gumby Suit.” This suit is amazing! This portion of the Pacific is quite cold and the Immersion suit would keep you warm and buoyant until a rescue can occur.

After our drills several of the science crew went up to the Flying Bridge to look for marine mammals. We were cruising between Cape Flattery, Washington and Vancouver Island, British Columbia with high hopes of seeing activity. WOW, we lucked out. We spotted 17 Humpback whales, 2 Harbor porpoise and 2 Dall’s porpoise. We are also seeing several types of sea birds but I am still brushing up with the Sibley to id birds from this area.

Did You Know?

The island cluster that we are heading to had a name change at the end of 2009. What was formerly called Queen Charlotte Islands is now called Haida Gwaii. This name change came as part of a historic reconciliation between British Columbia and Haida nation. Haida Gwaii translated means “island of the people.”
