Six Weeks in the Southern Ocean

Hello! This is Bethany; I am a post doctoral researcher at Yokoyama lab. I recently spent six weeks on a research vessel in the Southern Ocean near the coast of East Antarctica. While there, we took water samples and sediment samples, mapped the seafloor of the area, and deployed various instruments for the purpose of learning more about the production of Antarctic Bottom Water in this region. 

During this voyage, we had two successful Kasten core deployments off the coast of Antarctica. Both cores were around 3.5 m long and were sampled for a variety of analyses. We also deployed a piston core which recovered about 15 m of sediment. These core sections will be split and sampled later onshore. 

Efficient sampling of the Kasten core 

Preparing for the piston core arrival on deck
- the core needs to be cut to 1m lengths

In addition to the sediment sampling, we took water samples from more than a dozen different water depths at five different sites using the CTD (conductivity, temperature, density) rosette with 36 niskin water bottles attached to it. These water samples will be analyzed for carbon, oxygen, various metals, diatoms, and radiolarians in an effort to learn more about ocean currents and the interaction of different water masses.

Neatly packed water samples

A new experience for me was using the CPR – not cardiopulmonary resuscitation, but rather the Continuous Plankton Recorder. This is an invention of Sir Alister Hardy and Sir Cyril Lucas which is still in use today with not much change in design over the past 100 years. The CPR is deployed off the stern of the ship, and as it is pulled through the water plankton is caught between two long silk sheets which are then spooled together around a pin. In this way, plankton caught between the silk sheets can be analyzed later after retrieval of the CPR. 

Loosening the bolts of the CPR to switch out the silk spools 

The transit south from Australia took 11 days. On the way, we encountered a bit of a storm and saw 8-10 m swells. The biggest wave during the storm was 23 m! 



Big wave a few days after the storm.
Imagine how big they were during the storm!

Also on the way, we saw many, many types of birds including a variety of albatross and petrels. It was very exciting to see our first iceberg as it meant we were getting closer to the study site. Experiencing the lengthening of days was also quite interesting. 

Iceberg!

One highlight of the trip was being able to see the Aurora Australis one night as we were on our way back to Australia. Beautiful green ribbons filled the sky against a backdrop of the Milky Way while the light of the full moon reflected off the ocean.

As often happens, the plan for science did not go as expected. Due to extenuating circumstances, it was necessary to turn back after three days at site. We made the most of the transit back to Western Australia with deploying the CPR and Argo floats on the way. Argo floats make continuous measurements of temperature, salinity, pressure, and other biogeochemical measurements while drifting at depth, and the data is occasionally transmitted back to the data center. We were also able to recover one more Kasten core and more water samples on the way from Western Australia to Hobart, where we disembarked.

A view of our parking space :)

Looking forward to more voyages and collaboration with the amazing people on board!

Glacial Sedimentation School at Oregon State University

At the end of May, 2022, I was afforded the opportunity to attend Glacial Sedimentation School (GLASS) hosted at the marine core repository at Oregon State University. The core repository was finished in 2020, and this workshop was the first event to be hosted at the new facility. There are over 35 km of marine sediment core from thousands of sites in the world’s oceans stored here, all available upon request.

One aisle of the refrigerated room at the core repository

The refrigerated core repository at Oregon State University

There were 26 students from multiple countries in attendance, and we were split into four groups, each group in charge of analyzing a set of cores. My group had the privilege of analyzing four sections of the ANDRILL 1B site extracted from the Ross Sea, Antarctica. The ANDRILL 1B core, drilled in 2006, broke a record at 1284.87 m long, the longest drilled core at that time. It was first necessary to drill through ~85 m of ice and 900 m of water before reaching the seafloor sediment. 

Two sections of the ANDRILL 1B core

We started with core descriptions, detailing the visual aspects of each section: laminations, bioturbation, whether or not there were clasts, etc. The next day we made smear slides, focusing on areas of the cores we found to be particularly interesting. Looking at the smear slides through microscopes, it was possible to assess the abundance of silt, clay, and biogenic sedimentation in different deposits in the core. On day three we took our cores to the physical properties lab and analyzed density and magnetic susceptibility. The final lab day we determined the chronology of our cores using magnetostratigraphic and biostratigraphic data. We presented our results on the fifth and final day of the workshop.

Drying the sediment on slides
After they were dry, we applied glue to a cover slide and placed it on the dry sediment

Glue drying under UV light

Physical properties analyzer for density and magnetic susceptibility

In addition to the above lab work, each day, our instructors and mentors would give lectures pertinent to our analyses. Some lectures were on different types of corers, using seismic data to select drilling sites, and how to construct an age model, among many other topics. This workshop was an excellent introduction to practical skills needed for physical core analysis. It was also a wonderful opportunity to meet peers from around the world working on projects similar to mine; one of my team members and I had actually worked on samples from the same core. I also met in-person someone I had previously only known through online meetings. It was so interesting to hear about the various research everyone was doing, and I look forward to meeting again, and perhaps collaborating with, those I met at this workshop in the future.

GSA 2021, Portland, USA

At the Geological Society of America 2021 meeting in Portland, Oregon

One of Washington's mountains, perhaps Mt.Adams

From October 10-13, 2021, the Geological Society of America held its annual meeting in Portland, Oregon, USA, and I was given the opportunity to attend and present my results on beryllium ratios in Antarctica during the past 10,000 years. With correct/complete preparation measures for traveling during a pandemic (vaccinations, coronavirus tests, coronavirus passport/certificate, packing plenty of masks), traveling from Japan to the USA went smoothly.


A view of Portland's autumn colors


After arriving on Saturday, I joined the evening Meet and Greet at the conference center and talked with Matt who had attended a geomorphology conference in Chiba, Japan some 20 years ago – a bit of a coincidence since I live in Chiba. 

The main events and sessions started on Sunday morning and ran through Wednesday evening. Presentation topics ranged from mass extinctions to medical geology, Mars Rover analyses to the effects of specific micronutrients on the growth of squash. The presentation (and poster) I found most interesting discussed the results of Antarctic sub-fossil Adamussium Colbecki (shells) used as a proxy for sea ice during the past ~ 10,000 years. 

The Oregon Convention Center

Due to the coronavirus, attendance was about 30 % what it usually is, but still an excellent opportunity to learn about others’ interesting research. Looking forward to the next GSA in Colorado – my home state!
