Barium in the Arctic Ocean

Barium? Why would you want to measure barium in seawater?

Barium is a metal, and is dissolved in seawater in very low concentrations – for every litre of seawater there’s only about 0.00001g of barium. This amount isn’t fixed and varies around the ocean. Scientists have noticed that barium seems to correlate with other things in the ocean, for example the nutrient silicic acid (dissolved silicon) and alkalinity (which is basically the amount of ions in the water). Linked to this, barium has been thought to be useful in the Arctic as a tracer of river input (especially in winter when there’s not much biological activity that can also take up barium). However, this use of dissolved barium hasn’t been explored fully, and there haven’t been any studies to look at how dissolved barium behaves from one season to the next.

In a new paper, published in the Journal of Geophysical Research Oceans, we investigated barium in seawater and sea-ice from the Arctic. We collected samples during the Norwegian funded N-ICE2015 project, which was set up to study the physics, chemistry and biology of sea-ice in a changing Arctic. The Norwegian Polar Institute led the expedition, freezing their ship – the R/V Lance – into sea-ice north of Svalbard and taking a lot of measurements and samples as it drifted through the Arctic.

The barium measurements showed that there was no simple relationship with freshwater input, even in winter when biological activity was very low. This points towards an important process – likely within sea-ice – that is controlling barium distribution. Whilst this observation puts a question mark over using barium as a river tracer, our results do highlight the importance of understanding the chemical reactions that go on within sea-ice: in a changing world where sea-ice is diminishing, not only are we fundamentally changing the physics of the ocean but also the chemistry, with knock-on effects on marine biological production.

IsoGlace: Novel isotopes in glaciated environments!

On March 23rd, the University of Bristol hosted the IsoGlace workshop about novel isotope systems in glaciated environments. The workshop was organised by ICY-LAB’s Kate Hendry to coincide with a visit from UoB Benjamin-Meaker fellows Ellen and Jon Martin, from the University of Florida Gainsville, and featured talks from glaciologists and geochemists about how we can use isotopic measurements to understand glacial processes today and in the past, with a view to how these systems might change in the future. The talks (which included some exciting new ICY-LAB results!) were followed by discussions on the key questions, and how we might be able to address them through future innovations and collaborations. The university welcomed visitors from all around the UK, including colleagues from Southampton, UCL, Imperial, Nottingham and Cambridge. The day was a great success, and everyone left brimming with ideas!

Many thanks to the Jean Golding Institute and the Cabot Institute at the University of Bristol for funding, and to the School of Geographical Sciences for the use of their lecture theatre and facilities.

New from Old, Maybe

by Timothy Culwick

A new method of identifying old sponge specimens using DNA mini-barcoding.

Sponges are some of the most diverse and varied of the aquatic invertebrates with about 7,000 species described so far (Hooper 2002). Their success and morphological variability results in major problems with specimen identification. Due to similarities in hand specimen features a microscope is often needed to apply the appropriate Order let alone species separation. This difficulty is compounded in deep marine environments where much of the data come from camera drop images or broken fragments from trawling.

In Marine Biodiversity, Cardenas and Moore (2017) describe a new Geodia location on New England sea mounts and test a new way of specimen identification using mini-barcodes.

In the North Atlantic there are large sponge grounds on the slopes and shelves with most of the biomass stemming from the Geodiidea and Ancorinidae families. The grounds are both potentially ecological and environmentally important due to their size and extent. Geodiidea form the largest of the sponges in these grounds with single sponges getting up to 1m in diameter. Whilst comparatively easy to identify from large undamaged specimens due to its external morphology, broken or small specimens are much harder to separate. The damaged and diminutive species currently rely on spicule morphology which is difficult for non-specialise.

Molecular phylogeny of the Geodia genus, from Cárdenas et al. (2013: figure 2). Maximum-likelihood tree made from concatenated sequences of COI (Folmer fragment) and 28S (C1-D2 domains). Bootstrap nodal support values are given above the nodes: *, ≥ 75%; +, ≥99% (2000 replicates).

DNA Barcodes for Geodia species in the North Atlantic have been studied before (Cardenas 2013). They looked at the Folmer cytochrome oxidase subunit I (COI), 28S and 18S. of which both 28S and COI were unique for each species. Although due to slow evolution, identification of close species is limited (Schuster 2017). 18S was reported to be unique for four species but identical for two others. 18S has been previously noted to be conservative and therefore not useful for barcoding. However, this study relies on material to have no degradation of the DNA. Here we run into a problem with whole barcode sequencing. There is a limited number of specimens due to the challenge of collection at the depth and many were collected before DNA sequencing was possible. This is particularly true for most holotypes. These specimens were, and most still are, preserved using methods that degrade DNA making this type of analysis impossible.

The new specimens described by Carden and Moore (2017) were fixed in formalin which breaks down DNA so were unable to obtain a full-length barcode. They tried extracting two mini-barcodes the universal mini-barcode (=first 130bp of the Folmer barcode) and the Depressio-mini-barcode (= last 296bp of the Folmer barcode). Both barcodes hold the advantage of using an established barcoding database, so time and effort is not required to create one. The universal mini-barcode was obtained for five out of eight specimens. As with the full barcode it could not distinguish close species but importantly they all unambiguously identified the Geodia genus. This level of identification although superficially arbitrary for an organism within this phylum this is very helpful. The Depressio-mini-barcode was as sensitive as the full-length barcode with these specimens. However, it has not been used as a tool for identification on other sponges so should be treated cautiously. The potential sensitively suggested from this study is very striking and would be of great interest to look at further.
The most interesting part of this paper is what they went on to do next: they tried this mini-barcoding approach on two old specimens which would usually be considered unusable for DNA analysis. The first was a 11-14yr formalin fixed specimen from which they retrieved 100-300bp sequences. The second was a 161yr old dry holotype where two mini-barcodes were obtained. These hints of a method to open up the large proportion of collections to potential analysis which would otherwise be unusable. However, only two old specimens were tested and only one of the mini-barcodes can be considered reliable at this time. I don’t think the authors when far enough with this avenue of the paper to extrapolate the value of this technique as far as they have. There is great potential to increase the reliability of the sponge barcoding data and to look at many phylogenetic and taxonomic questions (Erpenbeck 2016). It would have been interesting to have tried with multiple samples to give an idea of the reliability and frequency of which results can be obtained. This is an interesting new avenue of DNA sequencing and could yield valuable results, but it needs further work to become the staple tool that is suggested.

Wrapping up!

And so, we’re nearly there!  We’ve sailed across the Atlantic, from our final station on the southern tip of Greenland all the way back home. We’re currently sailing through Irish Waters, due to pass by the Lizard sometime in the early hours of tomorrow.


We’ve had an incredibly busy, and successful, expedition (and I think that we’re all in need of some rest!).


We have collected or filtered approximately 28,000 litres of seawater; over 50 metres of marine sediments; and 1551 biological specimens (across 10 Phyla). The ROV dived for over 186 hours (over a week!) and we surveyed an area over twice the size of Wales…


During that time, we ate 1000 kg of carrots, 400 kg of potatoes, 280 l of fruit juice, 52 kg of baked beans, and went through 2000 tea bags. We also ate one whole bag of frozen broad beans.


But aside from all the science we meticulously planned, what are some of the concluding thoughts of the scientists onboard?

The day I learned how to de-goo a Bamboo Coral

Hello Everyone!


My name is Rebecca and I am a 3rd year PhD student from the Dauphin Island Sea Laboratory and the University of South Alabama in the USA. I call myself an aqueous geochemist by training, and I mean this is the truest way possible. I was invited on this cruise to work with radioactive silica and help with all things water chemistry- or so I thought…


I have spent the last 9 years of my educational career with my head in the sediments and water column, and avoided at all costs all things gooey, slimy, sticky or smelly. Yes, I work with algae, diatoms and sediments, but deep-sea biology is a world that I am completely lost and uncomfortable in. I have been on multiple research cruises, but they mostly focus on CTD cast after CTD cast, with samples coming from the water column and the sediments we collect along the way. But an ROV?! This is a whole new world full of spikey, spongey, living things that unfortunately must be cleaned, sorted and labeled when they arrive back on deck. As we hadn’t collected any new water samples for me to occupy my time with, I decided to help the biology team with its newest arrivals (this involved wearing as many layers as I could possibly manage, so I didn’t freeze in the cold room). I showed up to my new position and our fearless leader, Michelle, asked “How do you feel about goo?”. I guess my face said enough, because I was blessed with the task of de-gooing the meter-long bamboo coral (Isididae) that had just surfaced. Now this is not a task for the faint at heart, or those with a weak stomach…


The coral presented to me looked like a tree branch, roughly 4 feet long, but covered in a bumpy, slimy coating that had the consistency of something you would cough up when you are sick and a smell that I’m not sure I will ever forget. As I spent the next 20 minutes scraping off the goo and carefully collecting the gelatinous skin that this creature carefully created over its lifetime, I couldn’t help but laugh at myself. Here I was, a lifelong marine scientist squirming at coral goo, but nevertheless taking the task in full stride. When it was all said and done I earned a passing grade with my de-gooing skills, but I also learned more than I ever thought I would about the creatures living at the bottom of the seafloor. As each new bucket was brought into the cold lab there were ooohs and ahhs of excitement. How do these sponges make such amazing structures? Where do these bright colors come from?  How do the marriage shrimp get trapped inside the sponge together- do they love each other??


As we all scurried around sorting the samples I also realized something else, perhaps the most important thing about research cruises is collaboration. As sediment geologists, water chemists, radioisotope chemists, physical oceanographers and biologists all huddled around these samples I realized that oceanographic discovery would not be possible if we did not work together. Science can become compartmentalized very quickly and often if you go into the lab next door, you don’t really know what’s going on. But on the open ocean you become a family of misfit skills and everyone lends a hand.


For now I’ll go back to my water samples but if anyone needs some epic de-gooing skills, let me know!

Nature’s great Ice Temple

“…the limits of the unknown had to recede step by step before the ever-increasing yearning after light and knowledge of the human mind, till they made a stand in the north at the threshold of Nature’s great Ice Temple…”

–Dr. Fridjof Nansen, Farthest North


This morning we awoke to the news that we had spent much of the night being chased off station by floating icebergs. As the sun rose, it glinted off of more than a dozen icebergs within easy reach and later, as we scanned the seafloor for good sites to take sediment cores, we had to stray from our search lines to avoid colliding with the floating giants.


Despite the fact that they are literally putting kinks in our plans, I have to admit to being thrilled by the sight of these gleaming sculptures of ice. Not only do they make for spectacular photographs, they’re also the modern analogue of the phenomenon I’m studying aboard the Royal Research Ship Discovery.


My name is Allison Jacobel and I’m a postdoctoral research scientist from Columbia University’s Lamont-Doherty Earth Observatory. Together with Grace Cushman, an undergraduate at Barnard College, I am studying the record of Earth’s past climate preserved in marine sediments. They may not look like much, but these layers of sediment, from deep below the waves, tell us about the ocean’s past temperature, salinity, productivity and how it moved heat around the planet.


Grace and I are particularly interested in the record of rocks and other terrestrial debris deposited by icebergs. These pieces of ice rafted debris were picked up by glaciers on land and as the icebergs melted at sea they deposited their load of pebbles (and sometimes even boulders) in the sediments below. Just as the icebergs floating outside our portholes are a consequence of ice melt from Greenland, the record of icebergs in the marine sediments indicates past melt.


Twenty thousand years ago, Long Island sat at the foot of an enormous glacier fed by an ice sheet that covered the greater part of North America. This was the Last Glacial Maximum, the most recent ice age. Our transition from the LGM, when Boston was covered by almost a mile of ice, to the warm climate of the present was not a smooth one. Research has shown that the transition was punctuated by catastrophic floods of icebergs that disrupted ocean circulation. Studying the history of iceberg melt is thus a valuable way to help us understand abrupt changes in climate and to shed light on the sensitivity of the climate system to additions of freshwater.


Today the Arctic is experiencing a rate of warming faster than any other place on Earth. Dramatic ice loss is occurring from the Greenland Ice Sheet and from the mountain glaciers that surround the Arctic. Although our work on the RRS Discovery is focused on past changes, our results are also important for modern climate prediction efforts. Models are currently equivocal about the future of the ocean’s overturning circulation and understanding how past inputs of meltwater affected circulation is critical to improving these models and climate forecasts.


The early 20th century polar expeditions of Nansen and other famous explorers were dedicated to expanding our geographic knowledge of the poles. Today, we know the shape of the coastlines and the safest routes for travel, but we are still working to push back the limits of the unknown. Not only are we learning the details of modern productivity regimes and deep-sea habitats, we are also using Earth’s own records to uncover its history, in the hope that we might help protect what remains of Nature’s great Ice Temple.

Coprolite and HSB

Two gliders; Coprolite and HSB, have joined us back onboard the Discovery, having been successfully recovered today. These are Slocum Gliders, which are bright yellow, 5 feet long, 50-something kilos with a trim waist. They manipulate Archimedes’ law to steer to different depths in the water and are remotely directed by pilots operating from Southampton.

During their week-long mission, Coprolite and HSB accumulated observations of the water column, ranging from temperature and saltiness to dissolved oxygen and chlorophyll concentration. They were released in the north-eastern Labrador Sea, where they weaved in and out of a strong boundary current not far from the Greenland capital; Nuuk.

This boundary current, known as the West Greenland Current, exchanges water between both Greenland’s large continental shelf and the central Labrador Sea. This includes large-scale eddies, created by the instability of the current structure, that export water westward to the Labrador Sea’s interior. These eddies influence the formation region of a globally important deep water mass in the Labrador Sea. Recently, observations have pointed to an increased Artic freshwater presence from elevated ice melt. This trend, carried by the West Greenland Current, may restrict the extent of deep water formation.

Moreover, biologically essential nutrients, like silica, are associated with meltwater delivered from Greenland’s glacial network. Their pathways into ecosystems are controlled by circulation features dependent on the West Greenland Current, but these important circulation features often happen on small scales in space and time. It is the sampling agility of the gliders that may provide a new perspective on the circulation features initiated by this immense current.

On recovery, a hushed atmosphere swept the ship’s bridge as we squinted through a band of fog and idle seabirds for the yellow fins of the gliders. The sea surface was calm and glossy. It had the texture of jelly, with corduroy-like ripples and the gliders seemed to gloop out of it as they were whisked up into the air.

Still wet from their journey, Coprolite and HSB rest with tired batteries back on the Discovery. The mountains around Nuuk fade away into mist as the ship steams south, and it scores the surface of the Atlantic waters as it does so. We are heading towards the Southern tip of Greenland where the orange sunrise and marmalade seas will shine the toes of different mountains and, our science investigation will continue.

Shannon a’Hoy!

Today I managed to catch our resident seafloor mapper aboard the ship, Shannon Hoy, coding extraordinaire and all-round lovely person for a quick-fire Q&A. Here she put up with my inane questions and shed some light on what she’s learning from generating maps of the ocean, from reef environments to the wider-scale abyssal geology under the waves of the Labrador Sea. Initially reading for a degree in Marine Biology, Shannon has been lucky enough to have worked on 10 expeditions at sea- spanning both Poles, as well as the international date line. She is currently working towards a Master’s degree in Ocean Mapping at the University of New Hampshire- Centre for Coastal and Ocean Mapping.

How did you get involved in cruise ICY-LAB?

I first met Laura Robinson and Kate Hendry (Chief Scientist) in 2011 during a research cruise to the Drake Passage in the Southern Ocean, and since then have taken up any opportunity to go to sea with them again!

What’s your role on the ship, and what motivates you to work in this field?

I run acoustic sonar systems to find out the bathymetry and geological features of the seafloor, as well as to find out locations of open-ocean populations and to look at physical parameters of the water column. Currently we are trying to map the boundaries between water masses based on their physical characteristics, which is really exciting! The physical oceanographers on the Discovery find this sort of information useful, as it ties in with how water masses mix and flow in the sea. A large aspect of my job is to add a spatial context to data that other scientists are collecting- this is important to support accurate interpretations of oceanic processes, by the addition of visual elements.

How does it work?

Transducers that are dotted along the outside of the ship send pulses of sound down to the seafloor. These bursts of sound get reflected back, and are heard by hydrophones also located along the ship. By calculating how fast these sound pulses travel through water, we can see how long it takes them to reach the seafloor. By repeatedly firing down pulses of sound we can work out the depth of the seafloor changes along a given trail, and therefore build a picture of what the seafloor topography looks like. For this cruise, we’ve been using this technology to locate seamounts and other places where we might be able to find seafloor communities for sampling!

What does your typical day at sea look like?

After getting up, I correspond with the previous watch about what happened over the last 12 hours. Then I make sure the multitude of screens are ticking over nicely and aren’t throwing up warning messages, and generally make sure things run smoothly. When they don’t, like when the sonars cut out, it’s a case of quick thinking and troubleshooting for my part! Taking data and presenting it in a visually stimulating way takes up a large portion of my time, and this is all fuelled by copious amounts of coffee and biscuits.

What’s been the biggest learning curve of this experience?

Typically, I’m the only one making decisions about how to properly set up this equipment and where to sample, so learning the systems to a sufficient level and relying on my own expertise to keep everything going has been the most frightening and beneficial aspect.

What’s your favourite bit of the job?

There’s nothing quite like uncovering and exploring swaths of the seafloor that no one’s seen before, as well as everything that comes with being at sea! I’ve done 3 cruises with the Bristol team, so learning about fossil corals as windows into past oceanic conditions has been really cool. As my undergraduate degree was in marine biology, having the opportunity to play with squishy things again has been great.

What’s your favourite part of living on the Disco?

The views, the food and the people. And that it’s so loud that no-one can hear me snore!

 What are you most glad you brought, and anything you wish you had?

I’m glad I brought my iPad and headphones to sate my desire for constant One Direction hits. I wish I brought slippers and a warm jacket!

Any advice for people who want to go down a similar route?

I think many people find ocean mapping via other avenues, so there’s no direct route to take. The ocean sciences incorporate a lot of disciplines, so for me dabbling in many fields has lead me to what I do today! Being at sea has been great for getting exposure to many aspects of scientific research and computer technology, so there’s a lot to learn and be enthused by.
