This post is part of a series about the 2018 STEM research cruise taking place this week on board the R/V Oceanus. For an introduction to the cruise, read yesterday’s post by the cruise’s Principal Investigator Tracy Crews. Today’s post is from a student’s perspective:

Today was the first full day at sea. Though much of the group spent yesterday in their bunks with seasickness, they all were present for today’s activities.

We woke and gathered in the dining area for breakfast before heading up to the flying bridge to observe marine mammals. There were patches of bait balls (groups of small fish) followed by flocks of gulls. Though we saw a few individual humpback whales, they were typically seen in pods of three or four.

During our whale observations, we witnessed a whale lunge feeding. This is when a whale lunges out of the water, exposing its enlarged buccal cavity which expands like an accordion to accommodate a large amount of water and the krill on which it feeds.

Seeing consistent whale activity led us to deploy the CTD to collect oceanographic data, and a plankton tow to observe the abundance of food available. Afterwards, we continued to observe the humpback whales. Though we saw many whales, not many flukes were visible, which made it difficult to photograph and identify the individual whales.

Styrofoam cups ready for deployment

Right before lunch we gave up due to increasing winds which made observations difficult, so we headed North to Astoria Canyon off the Columbia River to conduct a series of CTDs. During the deepest deployment, we attached bags of Styrofoam cups decorated by our group, as well as students from some of their classrooms. The cups were sent to over 700 meters depth causing them to shrink to half their original size due to the high pressure.

After recovering the CTD and cups, our group gathered to eat ice cream and enjoy the magnificent sunset in the West, mirrored by the full red moon to the East. Our last research effort for the night was another plankton tow which yielded more krill, lantern fish, a baby octopus, and many other cool critters.

Shipboard Experience on the Oceanus

Surveying the horizon for marine mammals and seabirds

This weekend, a science party of 13 researchers, students, and teachers gathered aboard Oregon State University’s research vessel, the Oceanus, to begin a four-day research cruise aimed at providing mentoring and career connections at sea. The team mission is to conduct marine mammal and sea bird surveys and correlate sightings with oceanographic data and prey distribution. Participants in this cruise include high school teachers and students from Bandon High School, Taft High School in Lincoln City, and Warrenton High School, as well as college students from Southwestern Oregon Community College, Oregon Coast Community College and Oregon State University.

Deploying the CTD

While adapting to life at sea, these teachers and students are learning to handle lines and deploy oceanographic equipment, how to identify marine mammals, seabirds, and plankton. They aren’t just observers but active participants in the science party, operating critical equipment, including hydraulics and data collection systems.

The first day we experienced sunshine and many successes. Participants mastered their seasickness, and went on to deploy and retrieve plankton nets and CTDs. The abundance and types of plankton (small floating plants and animals) captured in the fine-mesh nets, and the physical parameters of conductivity (salinity), temperature, and depth measured by the CTDs will help researchers characterize the water column.

In addition, we surveyed over a dozen humpback whales and numerous porpoises, and used a drone to capture video footage of a humpback whale from above. The video data will help researchers from OSU’s Marine Mammal Institute assess the whale’s body condition, an indicator of overall health.

Life on the water is often exhausting, and after a 14 hour day, we are all ready for some much needed sleep. Laying in our bunks as we are rocked to sleep, we dream of what tomorrow will bring.

Day Three on the R/V Oceanus

Posted on September 16, 2016 by Cait Goodwin

Internet access from the R/V Oceanus has been inconsistent, but education PI Tracy Crews has been able to send in some photos and observations via social media. Here are some of her observations, sprinkled with links to other blogs from other participants:

Our last day out at sea started with deploying the CTD in the Astoria Canyon in the dark. Our marine mammal surveys got off to a slow start but we were seeing a lot of jellyfish, juvenile sunfish, seabirds, and even some tuna. All of a sudden on the horizon emerged a large pod of Pacific white-sided Dolphins (40+) that started riding the bow of the research vessel. Before they had even departed, a large pod (30+) of finless Northern right whale Dolphins joined them. What a sight to behold!

***

The researchers from OSU’s Marine Mammal Institute estimated that we saw over 400 Pacific white-sided dolphins and Northern right whale dolphins today in addition to the numerous humpback whales we encountered. Another amazing day out at sea with Oregon coastal teachers and students!

What an amazing cruise it has been! Everyone soaked up the sun on the flying bridge as we made our way into the Columbia River where we dropped off our chief scientist and OSU graduate students before making our way to Portland where we will engage in two days of outreach activities. Our captain used a small boat to shuttle the researchers into Astoria so they can return to work tomorrow. Getting the science party and all their gear off the ship proved to be quite an ordeal involving a crane, step ladder, rope ladder and half the ship’s crew! We were sad to see them go and just a little jealous of their ride in the red rocket. We are grateful to them all for generously giving their time to share their knowledge and passion with us.

Day Two on the R/V Oceanus

Posted on September 16, 2016 by Cait Goodwin

By Tracy Crews

Day Two of our oceanographic cruise started with us once again surrounded by humpback whales feeding. In addition we have seen more seal lions and flocks of seabirds including some black footed albatross. Our teachers and students continue to shine as they deployed and retrieved another CTD (to measure Conductivity, Temperature and Depth) and collected and entered survey data into the computer on the fly bridge. Unfortunately, the weather turned overcast and chilly today forcing us all to bundle up.

Visit the GEMM lab blog to find out more about the marine mammals and birds encountered on Day Two.

Students and teachers have spent some of their downtime on the R/V Oceanus decorating styrofoam cups to send down to the bottom of the Pacific Ocean. Here are a couple of photos of the process.

Decorating the cups

The decorated cups were attached to the CTD that was about to be deployed.

Read Ms. Almasi’s blog about the science behind the styrofoam cup experiment

We used two sizes of cups. This photo shows the difference in size before (center) and after (sides) the cups were sent to the deep ocean.

Dr. Leigh Torres shows what the bag of cups looked like when they returned to the surface

The styrofoam cups made it back from their journey to deep, 1400 meters to the sea floor attached to the CTD.

The sunset was a glorious ending to a great day. Although we didn’t see as many whales today as yesterday, we did see numerous humpbacks, a couple of fin whales, some Dalls porpoises, and some Pacific white-sided dolphins, as well as some sea lions, albatross, and ocean sunfish (mola-mola). We have left the waters off Heceta Head and will be making our way towards Astoria Canyon overnight. Sweet dreams to everyone aboard and on land!

Huge pod of humpback whales put on quite a show for us lunge feeding and breaching. What a great way to end our first day at sea.

A huge group of humpback whales put on quite a show for us lunge feeding and breaching. What a great way to end our first day at sea!

What was Day One on the R/V Oceanus like for the students, teachers, and researchers on board?

Knot tying, safety at sea, deploying and retrieving scientific instruments, interpreting data, conducting effort surveys, and photo identification of whales….

…these are just a few things that teachers and students on board OSU’s research vessel Oceanus put into practice yesterday on the first day of a three day research cruise off the Oregon coast. Before even leaving the dock, participants started their training, learning about shipboard technology and donning survival suits during safety drills. Crossing the bar, we spotted the first marine mammals of the day: a few gray whales and California sea lions. During this cruise, teachers and students will get an in depth look at how researchers identify, track, and study marine mammals in Oregon waters and beyond, and how baththymetry and oceanographic conditions influence the distribution of these animals.

As the first day of the cruise progressed and we passed over Stonewall Bank, we spotted a small pod of humpback whales. As we transmitted south, we also encountered a pod of orcas. The grande finale of the day came early sunset when a large group of humpback whales (approximately 50) was spotted near Heceta Bank. They were lunge feeding, opening their huge mouths and taking in water and, presumably, lots of food. A plankton tow confirmed the presence of krill, which is a favorite prey item for humpbacks.

When we came across a huge group of humpback whales, we decided to take a plankton tow and found it chocked with krill.

With a final debriefing at 8:30 pm, teachers and students wandered off to their shared quarters excited but exhausted with a greater understanding of marine mammals and an appreciation for how hard researchers work. It was a great start to what we hope will be a successful experience for everyone!

Shipboard experience on the R/V Oceanus

Posted on September 14, 2016 by Cait Goodwin

Three Oregon high school teachers are among the participants working on the R/V Oceanus this week.

This week, students and teachers from the Oregon Coast STEM Hub are joining Oregon State University scientists aboard the research vessel Oceanus to gain at-sea research experience. The project, “Building the STEM Pipeline through Oceangoing Research and Near-Peer Mentoring” is a collaborative effort that aims to enhance critical STEM skills among coastal learners.

Read the OSU press release

The R/V Oceanus departed this morning from Newport and is headed for Astoria and Portland. Tracy Crews gives this report of their departure:

We couldn’t have asked for better weather as we departed Newport on our cruise offshore to conduct marine mammal and seabird surveys and collect oceanographic data. My first cruise as PI (Principal Investigator), we have 3 high school teachers, 4 high school students, an undergraduate student and 3 graduate students working with our chief scientist from OSU’s Marine Mammal Institute. We got our first glimpse of marine mammals (sea lions and gray whales) crossing the bar and have successfully completed our first CTD. A few seasick folks but otherwise we are off to a fantastic start!

Through this blog and the Oregon Coast STEM Hub Facebook page, you can keep track of the vessel’s progress, the STEM activities taking place on board, and even occasionally hear from the participants themselves. The following teachers and students are on board, representing several different regions within the Oregon Coast STEM Hub:

Josh Jannusch – teacher, Warrenton High School
Charlotte Watkins – student, Warrenton High School

Teacher Kama Almasi has a blog that she is using to connect back with her students at Waldport High School. Her first entry focuses on the colorful science of seasickness, but we hope no one will be collecting THAT kind of data on this trip!

RESEARCH
On their first day at sea, the students and teachers have been working with researchers and crew members to deploy and retrieve CTDs. These instruments collect conductivity, temperature and depth data to provide a profile of the water column.
