Carolina on board AMT29AMT29 is the longest oceanographic campaign I have ever participated and it has been very interesting in many ways.

Scientifically, it crosses different oceanographic regions which allows us to see in situ the characteristics of the various water masses and the changes occurring along the Atlantic. We have sailed in the North and South Atlantic productive waters, the oligotrophic gyres and crossed the equatorial region. While analysing the water samples we have the chance to observe those variations in the parameters we are measuring, in my case the Particle Size Distribution (PSD), and best of all, to discuss them with the multidisciplinary team onboard by comparing with their observations.

In the beginning of the campaign the Coulter Counter gave us a few headaches, but with the support of all, this was quickly solved, and I was able to make daily PSD measurements of samples collected at two depths during the CTD noon-cast.

During this campaign I had also the chance to contribute for the NASA’s AERONET Maritime aerosol network by taking measurements with a Microtops Sunphotometer sensor during clear skies conditions.

At a personal level, it was also very enriching to share my days with people from several different cultures (more than 10 different nationalities on board!) and understand that the ocean can also contribute to a world with no “walls”.

Guilia on board AMT29Participating in the Atlantic Meridional Transect has been so far one of the most enriching experiences I have ever had.

As a masters student in Marine Science, being in a research vessel across the Atlantic Ocean for more than a month surrounded by experienced scientists has been like a full immersion in everything I’ve been studying in books. A team of 20 scientists from 11 different nationalities were on board the RRS Discovery with the aim of studying the Atlantic ecosystem, being also an unique networking opportunity.

For me, the cruise has been a 24/7 intensive course in different fields (e.g. optics, phytoplankton ecology, oceanography) and I found particularly useful the weekly science meetings, where the various researchers could present and discuss their observations. The complementarity and multi-disciplinarity of the team allowed me to have a broader perspective and understanding of all the oceanographic processes occurring in the Atlantic.

Throughout this experience, I’ve been surrounded by great scientists who were always ready to help me and to give useful advice that will be very beneficial for my work back home. I’m feeling even more motivated to continue my career with a PhD in the field, perhaps with a possible collaboration with them.

Furthermore, at a personal level this experience allowed me to grow under different aspects. I found myself really comfortable with the demanding work schedule at sea, which also motivates me to participate in more oceanographic campaigns in the future. I am really thankful to the PORTWIMS project for giving me the opportunity to take part in this unforgettable experience.

I never thought I would have the opportunity to embark again on this Atlantic expedition, and I am very grateful I have been given this chance as in the first time (AMT28) I was quite nervous and took me a while to adapt to life on board, but now I'm more at ease and enjoying a lot the overall experience, despite the bad weather we have been through.

In this AMT29 I'm responsible for the pH analysis of all water samples collected from the CTD and for filtering plankton samples to study the coccolithophore communities in the framework of DUSTCO project.

The good team spirit and interdisciplinary knowledge of the scientific team results in cooperation and complementarity between some of the projects being conducted on this cruise. Each week there is a scientific meeting where we present what we are doing and discuss preliminary results. As a young researcher, participating in these meetings is helping me to broaden my perspectives and have a better understating of the oceanographic processes occurring in the Atlantic.

This experience is making me grow as a scientist and as a person, I hope to have similar opportunities in the future and for now I will try to make the most of it!
 


Alice Santos visits PML to learn about valuing ecosystem services

Alice Santos looking down a microscope at PMLFor three weeks, between October and November, I had the opportunity to join Plymouth Marine Laboratory (PML) within the PORTWIMS framework.

As a student from Lisbon University, doing my Masters in Ecology and Environmental Management, my dissertation thesis (integrated in the COBIO-NET project) aims to evaluate coastal ecosystem services (ES), particularly those provided by marine invertebrates in mangroves, seagrasses and corals along the coasts of Mozambique and São Tomé and Principe – detecting knowledge gaps and assessing the state, trends and key vulnerabilities, covering interactions with traditional practices.

The focus of this exchange relied on a collaboration with Dr Melanie Austen and Dr Stefanie Broszeit, both involved in the Blue Communities project. In this context, the main purpose of this partnership was to strengthen scientific knowledge and exchange ideas about methodologies of evaluation and quantification on the above-mentioned ES.

The experience of the exchange was extremely positive and successful, since both Dr Austen and Dr Broszeit are very dedicated and approachable, helping me to acquire useful skills and introducing me to new perspectives and approaches for my dissertation. Being so, I was able to make a lot of progress and return home even more enthusiastic and aware of the work I must keep developing.

I also had the opportunity to participate in the ACCORD training course, which had the holistic aim to help partner countries to build a resilient marine and coastal socio-ecological system and support their growing Blue Economies - doing so, I’m very thankful for having attended this course, since it helped me understand how a big project can work, besides giving me the opportunity to learn more than what I was ever expecting.

My stay at PML exceeded my expectations and I am very happy to have the opportunity to keep in touch with my hosts in the future.


Caroline Sá visits Plymouth Marine Laboratory

Last May, in the framework of PORTWIMS, I had the opportunity to work for three weeks at PML under the guidance of Dr. Giorgio Dall’Olmo. The objective was to start working with particle size distribution (PSD) and flow-cytometry data from past AMT campaigns in order to investigate the contribution of phytoplankton to the total particle size distribution throughout the Atlantic Ocean.

Until now I had mostly worked with HPLC pigment datasets for ocean colour applications and product validation focusing on the phytoplankton component (i.e. Chl-a and size-classes) off the Portuguese coast. This exchange program is allowing me to explore other types of data which can be complementary and understand the particle size distribution patterns at a different spatial scale: the Atlantic Ocean basin.

During these three weeks I have specifically analysed PSD data and developed a method to automatically extract the diameters of each identified size class using the Octave programming language. Staying at PML was essential as it permitted discussion of results and progress work on a daily basis as well as to plan and define sampling strategies for the AMT29 campaign.

I had also the chance to participate in the AMT29 preparation workshop and meet the colleagues and projects that will be conducted during the cruise; and I have jumped from a 3m height diving board to get my Sea Survival course diploma, which was required for participating in the campaign!

Overall this has been a great learning experience not only in terms of data processing but also in data analysis, interpretation and experiment planning. The work will now continue remotely until the AMT29 departure on the 13th October, where I will be responsible for making measurements of PSD in order to characterize its horizontal and vertical patterns throughout the Atlantic transect.
 


Mara Gomes, Polarstern, July 2019

mara_polarstern2.jpgPORTWIMS enabled Mara Gomes from Lisbon University to participate in the Polarstern cruise where she conducted research on radiometric properties for validation and taught the students about phytoplankton. Mara said "the participation of experts in different science and technology fields and curious young scientists made the expedition a life-changing experience".

On the South North Atlantic Transect (SoNoAT) of R/V Polarstern, Mara was responsible for teaching phytoplankton topics within the biology and microplastics module of the POGO (Partnership for the Observation of the Global Ocean) floating summer school. The focus was to give the opportunity to POGO scholars from all over the world to join a marine sciences expedition providing hands-on onboard research and laboratory training.

In her blog Mara said "The teaching experience on R/V Polarstern has been by far the one from which I learned the most, not only scientifically but from a social perspective. The participation of experts in different science and technology fields and curious young scientists was made this expedition a life-changing experience, both for teachers and students, and especially for me! Motivated by the same need to protect our blue planet, we will never stop exploring the oceans. For further information read Mara's blog post.

 

First PORTWIMS on-site training of FCUL young staff at AWI

Maria Gomes at AWI in front of the model of the RV PolarsternIn June 2019 the German RV Polarstern will be crossing the Atlantic Ocean from Port Stanley (Falkland Islands) to Bremerhaven (Germany) as part of the expedition PS120 programme. Within a wide range of research topics that will be covered during this cruise Mara Gomes, a masters student from FCUL, will be studying the ecology and distribution of phytoplankton communities living in different biogeochemical provinces of the Atlantic Ocean.

Scenery outside the AWI buildingIn collaboration with AWI, Mara will be running inline the AWI hyperspectral in situ spectrophotometer (AC-S) instrument to obtain continuous measurements of phytoplankton absorption spectra at the surface ocean along the cruise transect. The data will be further processed and analysed in conjunction with pigment concentration measurements (performed back home in the FCUL lab) when she is back from the cruise in order to derive a high temporally resolved data set on the overall and major phytoplankton groups’ abundance (indicated as chlorophyll concentration) in this ocean surface waters.

In order to gain the knowledge to run her measurements successfully, Mara spend one week in February in the Phytooptics Group (lead by Prof. Dr. Astrid Bracher) at AWI. Here she received hands-on training by the group’s technician Sonja Wiegmann on operating and calibrating the AC-S instrument and an introduction by the group’s PhD student Yangyang Liu into python analysis tools to further process the data. The AWI (Phytooptics Group) was happy to host Mara for the training, as she brought the sun from Portugal to northern Germany!
 


First PORTWIMS exchanges

Andreia Tracana and Afonso Ferreira preparing to leave for AMTAndreia Tracana and Afonso Ferreira had the 'experience of a lifetime' (Andreia) as the first participants to benefit from a PORTWIMS exchange. They set sail on-board RRS Discovery on the Atlantic Meridonial Transect (AMT) research cruise in September.

Afonso Ferreira said:
"AMT28 was a special opportunity all-round. I had the chance to work under two great scientists and professionals in Giorgio Dall'Olmo and Bob Brewin, from the Plymouth Marine Laboratory, who were not only always ready to help me out during work, but also made sure I had everything I needed during the cruise. As my first long research cruise, AMT28 was a challenge at several levels. The long working hours, the unusual work schedule and the fact that you're at sea for over a month can be quite stressful at times. In hindsight, however, I can say that our work was successful and my time during the AMT28 undoubtedly improved my ability to adapt and find a way to overcome difficulties during work. Plus, it was a privilege to be able to integrate such a helpful, large multi-disciplinary and diverse team. All in all, having the opportunity to participate in the AMT28 cruise was unique, and I hope to be fortunate enough to repeat the experience in the future."

Andreia described her experience onboard AMT:
"My participation in AMT28 was the experience of a lifetime. As a marine biologist, going on a oceanographic research cruise across the Atlantic Ocean, from Plymouth to the Falkland Islands, was one of my goals and the high point of my career so far. Being able to work on a ship with a scientific team from different countries and backgrounds inspired me to pursue to a PhD. My tasks aboard the cruise where demanding, but constituted a different and exciting experience. I have learned more than I could have ever expect, both professionally and personally and I’m quite excited to proceed my career with the knowledge obtained during AMT. I’ve also discovered that I’m able to work long hard hours and that I don’t suffer from sea sickness! I hope that more opportunities like this one appear in my path because this experience was indeed enriching in all aspects of my life and seeing icebergs and penguins for the first time was unspeakable, a memory that I will forever keep in my heart."
