Return to Sea: Seabirds, Seamounts, and Science

By Jessie Bolin (2019 student alumni)

I’m Jessie, a first year PhD student at USC, and I was lucky enough to be a student participant on this year’s CAPSTAN voyage aboard RV Investigator from Hobart to Fremantle. The focus of the program was to train Australia’s next generation of interdisciplinary marine scientists, and we were exposed to field and lab techniques in sedimentology, geophysics, plankton, hydrochemistry, physical oceanography, and fauna identification. This was my first introduction to life at sea aboard a scientific research vessel, and I was hooked.

I have just returned from my second voyage on RV Investigator, where we spent 28 days cruising around the Coral Sea. The primary voyage goal, led by Chief Scientist Associate Professor Jo Whittaker, was to further understand the spatiotemporal extent of mantle plume activity in the Coral Sea, and to investigate how features in the region formed, like the Tasmantid and Lorde Howe seamount chains, and the Louisiade Plateau. This was done by using dredges (think of a massive net with teeth) to gather rock samples from seamounts and ridges, and using the multibeam echosounders to map the seafloor.

In addition to the primary project, the voyage had other supplementary projects:

  • Understanding spatial links between geomorphology and biodiversity in the Coral Sea Australian Marine Park
  • Spatial and temporal variability in the distribution and abundance of seabirds
  • Collection of dead invertebrates dredged with geological samples
  • Transit over the likely wreck sites of the USS Lexington and USS Neosho
  • Educator on Board program

I was involved with the “Seabirds at Sea” project, and my role was a seabird and marine mammal observer for Birdlife Australia. A typical day for our team would involve starting observations at Monkey Island (the top level of the ship) just before sunrise, and recording the number, species, and behaviour of any observed seabirds and marine mammals through to sunset, using a standard survey protocol used since the 1980s. At the end of our journey through the Australian, Papuan, Solomon and New Caledonian EEZ’s, we recorded over 14,000 seabirds and 27 species.

Out of the 27 species, my favourite was the red-footed booby. They’re quite the comical bird, and at one point, we had over 50 red-footed boobies perched on the mast (…and scientific equipment), which broke a record for RV Investigator. Boobies feast on flying fish, and it was beyond exciting watching the boobies chase and catch flying fish that were disturbed by the ship. Flying fish can glide up to 70 km/hr to escape predators, which makes the boobies even more remarkable! Also, I witnessed my first instance of kleptoparasitism by a frigatebird. Instead of catching their own food, frigatebirds incessantly harass other birds – usually boobies – causing the victim to regurgitate their own food, which the frigatebird then steals in mid-air.

The Investigator is a ship for all scientists, which meant I was exposed to a diversity of perspectives and scientific research from completely different research areas to my own. Each day we’d have a ‘science talk’, where someone volunteered to give a talk about something they’re working on. Talks were diverse, and ranged from intraplate volcanism in Eastern Australia (Ben Mather, USyd), to using AUVs and ROVs to measure the spatial variability of algae under Antarctic sea ice (Vanessa Lucieer, UTAS), to methods of Ancient Egyptian mummy preservation (Quinn Anderson, USyd). Never in my life would I have thought I’d get to learn about Ancient Egyptian mythology on a research ship in the middle of the Coral Sea, yet there I was. We also celebrated international pet rock day, which was a real hit – particularly for the geology team!

A special moment for me (and many of the other scientists) was our final evening on the ship. The sun was setting, and we had just crossed into the East Australian Current on our way home to Brisbane. Seemingly out of nowhere, multiple pods of 50+ pilot whales and common dolphins appeared, and some of the dolphins started riding the bow waves! I’ll never forget the screams of excitement and complete joy that the marine mammals’ presence brought to the scientists and crew. They stayed with the ship for what felt like ages – it was a perfect end to a truly wonderful voyage.

For any budding marine scientist, I’d highly recommend going on RV Investigator. My background is in marine ecology and data science, yet going on this voyage meant I got to learn about marine geology and geophysics, and I even discovered a newfound interest for all things basalt and deep-sea volcanism. Being at sea for a month has taught me loads about the value of interdisciplinary marine science and working in a small, tight-knit community, and the experience has forged friendships for life. Thank you to the CSIRO Marine National Facility for a generous grant of sea time that made this voyage possible – I can’t wait to go back!

A day in the life of a sedimentologist

By Jin-Sol Lee, University of Melbourne

Although it would be hard to imagine, you couldn’t have seen a more excited group of adults than when a three-metre rectangular block of muddy sediment was pulled onto the ship. This surreal moment is when you realise you’ve fallen into the rabbit hole and entered a whole new world; the world of a sedimentologist.

This image of the stern (back) deck of RV Investigator shows the A-frame almost at its uppermost position as the 4 members of the crew and support staff work to deploy the kasten core off its track from the back of RV Investigator in a submarine canyon off Portland Victoria as part of hands-on marine science training for students on CAPSTAN's 2019 voyage.
Kasten core being pulled up from the depths of the Southern Ocean

This block of muddy sediment is a sediment core taken from the bottom of the ocean and reveals a whole plethora of wonderful and strange stories from Earth’s history. These stories relate to how our planet’s environment, climate, and ocean currents have changed over time. What is truly amazing is that we know so much about the long and dramatic history of our planet despite the fact that we have not been part of that history for very long. This amazement is humbling and is a reminder of the capabilities of the human race, and the responsibilities we have as stewards of the planet.

Once the core is brought into the lab there is a flurry of activity to open the metal casing, which holds the sediment core, and to see what strange and mysterious tales from the ocean depths have been brought to the surface. With the casing removed heads are bent over to observe the colour, structure and composition of the sediments. Quick, sharp remarks are exchanged between the various parties involved before the processing of the core is started without delay. First, the core is logged which involves documenting the major characteristics of the core. This is important because these observations will underpin the majority of the interpretations which brings the whole story together. From here smear slides and small sediment samples are taken along the core to examine the changes which occur from top to bottom.

The sediment lab is full of students and trainers as the kasten core (3 m long steel pipe) is opened on one side and imaged using a DSLR camera.  Students and trainers described the sediments, sampled plankton, and measured seawater properties as part of hands-on marine science training during CAPSTAN's 2019 voyage on RV Investigator.
The big reveal! A hub of activity as the core is brought into the lab and the task of processing and sampling the sediments begins!

Hours will be spent analysing these slides and samples, with more sampling done along areas of interest until the sediment core looks less than pristine. Not to worry however since before the sediment core was scooped, poked and prodded an archive core was taken and stored in the fridge. This archive core is kept with all its structures and features intact as an original record for safekeeping.

Hard at work! Sediment core being logged to describe the major characteristics and sediments being analysed under the microscope.

There is a certain amount of chaos and untidiness in the lab which may be disconcerting to the casual viewer, but there is a method to the madness with great care being taken to systematically record and sample the sediment core. Furthermore, there are efforts to limit contamination across the core (i.e. avoid mixing sediment from one area of the core to another). In fact, it is quite liberating to be able to conduct science in a lab where things are more practical, and improvisation is encouraged. A day in a life of a sedimentologist will surely shake up the perception of the typical scientist in a lab coat conducting experiments in a clean and well organised laboratory.

An unprecedented life experience in the middle of the ocean

By Umair Mumtaz, University of Western Australia

Today is the last day of the CAPSTAN research voyage IN2019_T01. My excitement is palpable as CAPSTAN has surpassed my expectations. The training provided in multidisciplines ranging from geology, geophysics, oceanography and microbiology will definitely act as a milestone for stepping into a future marine scientist. Time passes so quickly, I spent almost 12 days in the ocean and during these days I observed nature very closely, clear water, blue sky, sea birds and micro organisms with in the ocean.

This year’s training cruise was targeted on the canyon system on the eastern edge of the Bight Basin, near the outer continental shelf just southeast of Portland, Victoria. This region is unique due to the presence of cool water carbonate turbidite deposits. Such carbonate systems can only be formed with minimal terrestrial input. I was enthusiastic to see these carbonate systems as my masters research project is also related to the carbonates but they are formed in warm and temperate environment.

A bathymetric map of the canyon off Portland Victoria studied as part of hands-on marine science training on RV Investigator during CAPSTAN 2019.  Overlaid on the bathymetric map is color depicting the steepness of the slope with warm colors showing the steepest regions and cool colors showing the less steep regions.

Carbonate involves limestone and dolomite (rocks) that consists of mineral calcium carbonate (CaCo3) and dolomite CaMg(Co3)2 respectively. The organisms that live with in the water are zooplanktons (animals) and phytoplanktons (plants). They are made up of calcium carbonate and after their death they accumulated with in the water and after cementation and compaction, limestone is formed. It is important to understand carbonates because they can tell us about sea level changes, paleoceanography, paleoclimates, and marine ecosystems. They also holds around 50% of the oil and gas reserves.

A submarine canyon is a steep sided valley that extends from continental shelf to the sea bed. The turbidity currents carry material from the continental shelf passes through the canyon with an immense speed and may deposited with in the canyon and deep ocean floor. There can be many driving forces behind these turbidity deposits. These can be triggered by earthquake, gravity flows and tectonic forces. Due to density contrast between the sediments, the coarser ones will deposit first and finer will remain in suspension and deposited at the end.

Our chief scientist, Dr. Leah Moore selected specific depths for coring after looking at the bathymetry (geophysical) data. The bathymetry data uses acoustic (sound) waves to determine the geomorphological features of the ocean floor. The RV Investigator is equipped with the Kongsberg EM122 multibeam echosounders to retrieve high quality bathymetry maps. The cores were retrieved at 1700m, 2200m, 3700m and 4700m depths. I was working in the sedimentology lab to find out the variations in percentage of the fossils present in the top and bottom of each core. I was exposed to using the microscope to identify different foraminifera.

Another exciting thing was CTD as it was new for me. CTD stands for conductivity, temperature and depth. It consists of a carousel that has 36 niskin bottles with sensors at the bottom. In the operations room, a fluorescence curve that shows the chlorophyll activity with in the ocean and helps to decide the locations for samples. These bottles were closed at designated depths while coming back to surface. The polystyrene cups that were decorated by the students were sent down with the CTD to demonstrate the pressure affect. These polystyrene cups became very small in size after coming back from the ocean. Due to this small experiment, it is very easy to understand that pressure increases with depth.

Styrafoam cups shrunken to about the size of a shot glass can be seen in a pile in an onion bag.  These cups were sent kilometers below ocean and the pressure shrunk them from their original size.

On the very last day, we had a lot of fun. Our CAPSTAN director, Dr. April Abbott arranged a quiz to entertain all the participants and crew members. Everyone was in a different costume except me to relish those last moments. Our trainer, Stephen is a great geologist but his sense of humour was also amazing. I am obliged to be a part of this exciting opportunity as it not only increased my knowledge related to marine science but also helped me to thick critically, improved my confidence and science communication skills.

Sampling Seawater 101

By Jessica Bolin, University of the Sunshine Coast

Time is flying by – it’s day six of CAPSTAN Voyage #2, and we’ve now had the chance to explore different fields of oceanographic research during our group rotations: hydrochemistry, birds and mammals, plankton, geophysics, and sedimentology. Because we all have diverse backgrounds and areas of research, we’ve started to decide what our favourite stations are. My favourite, so far, is hydrochemistry, because we get to work with the CTD!

The CTD (conductivity, temperature, depth) rosette containing the CTD sensors and surrounded by 36 niskin bottles for discrete water sampling is deployed over the side of RV Investigator as part of the hands-on marine science training on RV Investigator through the CAPSTAN program
The CTD being lowered over the side

CTD stands for conductivity, temperature, and depth, and is one of the main pieces of scientific equipment that oceanographers use, because it measures changes in water properties throughout the water column. The CTD we’re using on board the RV Investigator holds 36 ‘Niskin’ bottles in a circular rosette frame, which is lowered from a huge boom on the starboard side of the ship, into the depths below. Upon deployment, each bottle’s plug is held open under tension by a spring-loaded metal hook. It’s an impressive piece of gear – the frame is taller than me (1.8 m), and each bottle can hold up to 12 L of seawater.

Bathymetric map showing the submarine shelf break canyons near Portland, Victoria in the Great Australian Bight.  Four major canyons are visible, one shaped like a Y is the main focus of our study.  The image shows shallower depths in red and greater depths in blue.  Bathymetric data was collected along with sediment and water sampling as part of the hands-on marine science training on RV Investigator through the CAPSTAN program.
Bathymetric map of our study area. Our site is the Y shaped canyon (third from the left). We’ve deployed the CTD at various depths along the canyon.

Our target site is a submarine canyon near Portland, Victoria, and we’re dropping the CTD at various sections along the canyon to further understand the circulation and other physical processes occurring within. As the CTD descends through the water column, sensors attached to the bottom of the frame sample the water’s properties, including temperature, oxygen, and conductivity; the latter which is used to calculate salinity. The data are pinged back to the ship’s operations room, where we all watch the vertical profiles of these parameters developing in real-time.

Fellow CAPSTAN student Sian sites in the operations room on board RV Investigator in front of several computer monitors to operate the CTD deployment.  She is watching the CTD parameters (temperature, depth, conductivity, oxygen, and chlorophyll) read out in real time to determine the depths at which to fire the niskin bottles and communicating with the winch operators as part of hands-on marine science training through the CAPSTAN program.
Sian sits in the operation room viewing the different CTD parameters in real time, and getting ready to fire the niskin bottles as the CTD ascends through the water column.

Once the CTD has nearly reached the bottom and starts ascending to the surface, each bottle is remotely ‘fired’ by an observer in the operations room at regular depth intervals. ‘Firing’ a bottle relays a signal to the CTD to release the hook on the target bottle’s plug, closing the bottle and trapping the water at that depth inside. After we have fired every bottle, the CTD is carefully retrieved by the crew and prepped for subsampling on deck… and the real fun begins!

CAPSTAN trainer Veronica Tamsitt samples a niskin bottle on the CTD rosette on board RV Investigator as part of the 2019 CAPSTAN voyage

From each bottle, we’ll take three subsamples of water for further testing: one to test for nutrients, one for salinity, and one for dissolved oxygen, whilst also recording water temperature. From these subsamples, we can calculate the density of the seawater, which is a primary driving force for major ocean currents. It blows my mind to think that the water we’re working with has come from up to 2200 m within a submarine canyon, which in turn, has travelled along ocean currents all over the world!

It is safe to say that I’ve developed a new-found love for physical oceanography and all things ocean currents. The ocean is inherently dynamic, and constantly changes in real-time. Teasing apart the mechanisms underpinning the circulation within our site is both challenging and fascinating. Once we start processing and analysing our data, we’ll hopefully be able to pick up the signature of the Flinders Current that flows west along the Great Australian Bight, and perhaps internal waves from within the canyon. Also, with a bit of luck, *fingers crossed* we can pick up the signature of a deep-water ocean current, that Veronica Tamsitt – our token physical oceanographer on board – recently discovered in the Bight, and collect some much needed data to ground-truth the current’s existence. In short, we are discovering SUPER exciting stuff this voyage, so stay tuned!

Welcome to CAPSTAN voyage 2

By Maddie Brown, University of Melbourne

How many scientists does it take to play a board game? Enough to break the ice.

image4.jpeg

Welcome to CAPSTAN Voyage 2, a collaborative program to give young scientists an opportunity to experience marine research and life at sea. Step one of our journey required an introduction to each other and to the various disciplines that fit under the marine research umbrella. Geology, Chemistry, Biology, Oceanography and Geophysics just to name a few. One of the best ways we found to get to know each other was by playing board games at our accommodation in Hobart prior to boarding the RV Investigator. Teams were created and friendships born through rummy-cube, Monopoly and Settlers of Catan. It’s amazing how easily the group connected with their common logical minds and strategic thinking, qualities that are often associated with great scientists.

The CTD rosette goes into the water.

Our target stations are located just off Portland, so we spent a few days adjusting to shift work and familiarising ourselves with the ship. Geophysical data was collected continuously throughout our journey to help understand the bathymetry around Tasmania and Victoria, this will be continued right through to Fremantle. Day one at our first station and it was all systems go, the CTD rosette was loaded and ready to be winched off the ship to collect hydrochemistry data through the water column down to 1700 metres. The CTD collects samples at intervals through the column, directed by the Operations Room which we had the privilege of viewing and assisting the direction.

In addition to the CTD, coloured polystyrene cups were placed in an onion bag and sent with it, to showcase the increase of pressure with depth. After the CTD returned to the ship, the bongo net was put over the edge to collect plankton samples in shallow water depths (40 metres and 100 metres).

The last collection at this station was a Kasten Core, which is used to collect 3 metres of sediment below the sea floor. On top of all of this, bird and marine mammal counts were being conducted from the viewing point on the ship. We have been lucky enough to see several species of albatross, petrels, shearwaters and prions. We even saw six seals having the time of their lives hanging around the ship. Speaking of wildlife, the team of young scientists had some spare time at night to wind down. Naturally, we bonded over watching appropriate films, such as Finding Dory.

We are only at the beginning of our journey through to Fremantle and I know there is so much more to learn. I’m already so grateful for what I have experienced and I can’t wait to wake up tomorrow to see what new knowledge lies ahead.

What a trip!

With an incredible crew, wonderful trainers, enthusiastic students, and favourable seas we couldn’t have asked for a more successful CAPSTAN pilot voyage!

The last full day at sea was an appropriate end to an epic 13 days crossing the Great Australian Bight. Students recapped the research results, our sea bird counts soared (# of total individuals increased 4x over the last day), we had regular marine mammals checking us out, and flat seas allowed the drone back into the air! The day was split between observations, presentations, writing, cleaning, and some celebrating!

DSC_0775A seal was snoozing peacefully until we came along!

The morning was busy as students finalised their presentations, trainers cleaned the laboratories, and everyone took some time to enjoy our surroundings! Student groups presented their findings to the science team after lunch- each team a demonstration of the importance of interdisciplinary collaboration! The research completed in a short 4 days on station is incredible, especially considering over-the-side deployments ceased at night.

Not only did the students’ ability to relate data across disciplines show, but their science communication skills also got a chance at the spotlight. Elise even broke down the importance of interdisciplinary approaches by relating the benthic ecosystem to by far the most popular board game of the trip, Settlers of Catan (one night after dinner 20% of the people on board were all playing at the same time!) – assigning each resource (wheat, wood, brick, etc) to an important ecosystem component (phytoplankton, benthic organism, sediment composition, etc).

It is hard to believe we’re back on shore already- we’ll miss our ship family! Who knows, we may even see some of our students back as trainers in the years to come!

FullSizeRender.jpg

The bow of the ship was busy most of the day, as calm seas and our proximity to Tasmania made for a beautiful sight and lots of marine visitors!

Stay tuned to the CAPSTAN website and this page as we start to look ahead to voyage 2019!

Real Work Experience as a Petroleum Geoscientist

Muhammad Rashid Saleem, University of Western Australia

I Muhammad Rashid Salem, from University of Western Australia, express my feelings during Collaborative Australian Postgraduate Sea Training Alliance Network (CAPSTAN) 2017 program and my significant learning and achievement in different aspect such as geophysics, sedimentary geology, paleontology, and oceanography that helped me to get better understanding of marine geoscience processes.

Screen Shot 2017-12-04 at 4.25.14 PM.pngI characterise sediments through the microscope in one of the labs on board

Working on offshore as a petroleum geoscientist was my dream and this dream comes true just because of this uniquely tailored scientific research program. Working as a petroleum geoscientist student from the University of Western Australia in CAPSTAN program gives me an opportunity to work hands on in professional environment and gain actual work experience in the field. This scientific research program gave me an opportunity to interact with researchers from different universities and CSIRO professional staff; and helped me to improve my communication skills in professional environment. Personally, this research has introduced me to a lot of useful resources in my field. I hope the skills, which I achieved during research will be a tool to improve my chances as a job applicant and assist me to become a better employee in my area of interest.

Screen Shot 2017-12-04 at 4.25.21 PMOur chief scientist takes a phone call in the operations room

What’s fun?

Visiting the sites! It is very interesting to get on the back deck with other teaching staff and ship members to collect the cores and rock dredge material that come out of the sea floor surface. The study of deep ocean sediments under the microscopes in wet laboratory helped me to recognize different facies and their fossils. Other interesting studies include geophysical data to map the sea floor surface and to know about sub bottom profile and hydrochemistry to know about temperature and salinity of ocean.

Screen Shot 2017-12-04 at 4.25.43 PM.pngCAPSTAN students and trainers recover a gravity core

Entirely, I learnt about geoscience in depth and realize how important the data is, which we collected during over fieldwork for petroleum prospective. My favorite times are when everyone including staff gets together during free time and discuss the things in friendly way. Last but not least, I want to say thanks to chefs and kitchen staff for their delicious dishes and their care about my food will always be remembered.

 

What’s challenging?

Life in the field is always hard especially when you are working offshore for the very first time, but I am very fortunate to have cooperative teaching staff and student from different universities worked as a team and make this scientific research very easy. Keeping up everyday routine to perform different task are challenging, but in a good way – it pushes me and make me stronger to learn and improve my skills.

Screen Shot 2017-12-04 at 4.25.57 PM.pngA sediment grab is brought on deck

My advice to upcoming CAPSTAN group is that working on this scientific program is very interesting and rewarding but make sure that be prepared to work hard in challenging environmental conditions. If you are adventurous, though this opportunity will be right up you alley!
