‘The Ocean We Need’ – Europe’s Leading Ocean Experts Launch Advice For Governments

The European Marine Board has recently launched a publication, titled ‘Navigating the Future V’, which will provide European governments with robust, independent scientific advice and expert opinion on future seas and ocean research to 2030 and beyond. To achieve this, leading ocean experts have identified the key areas of marine science where there are still gaps in knowledge.

 

The European Marine Board (EMB) is a leading European think tank in marine science policy. It is an independent non-governmental advisory network with a membership comprising more than 10,000 marine scientists from the major national marine/oceanographic institutes, research funding agencies and national networks of universities from countries across Europe. The Board provides a platform for its member organizations to develop common priorities, to advance marine research, and to bridge the gap between science and policy to meet future marine science challenges and opportunities.

Navigating the Future V

The knowledge gaps that Navigating the Future V (NFV) advises to prioritise in the research agenda is critical in understanding the four-dimensional ocean, to predict tsunamis and the impact of multiple stressors on biogeochemistry and biology, and to understand the impact of the future blue economy on our marine ecosystems. NFV shows that we need transdisciplinary science and sustainability science to address the management of a holistic four-dimensional ocean. It also highlights the technological advances and modelling needed for a possible future virtual ocean that would enhance public engagement and understanding of the ocean.

NFV proposes the science we need for the forthcoming United Nations Decade for Ocean Science for Sustainable Development (2021-2030), the next European Framework Programme, Horizon Europe, and its Mission on Healthy Oceans, Seas, Coastal and Inland Waters. The report was officially launched on 11 June 2019 in Paris, France, at the EurOCEAN 2019 Conference (High-level science-policy conference co-organised by European Marine Board, the European Commission and the Intergovernmental Oceanographic Commission of UNESCO).

Key Messages

Specifically, the report recommends a solutions-oriented marine research agenda, co-designed with all stakeholders, and with the governance of sustainability at its core. It should address the following key knowledge gaps:

  • The four-dimensional ocean (changes in the three-dimensional ocean over space and time) and functional links between the components of the marine system, i.e. physics, chemistry, biology, ecology and humans;
  • The impact of multiple stressors (e.g. climate change, pollution, overfishing) on the functioning of marine ecosystems, their interactions, evolution and adaptation over time, and the ecosystem services they provide;
  • The characteristics, probability and impacts of climate-related extreme events and geohazards (e.g. marine heat waves, meteotsunamis and submarine earthquakes, landslides, volcanic eruptions and their associated tsunamis) and how these might change under climate change; and
  • Ocean technologies, modelling, data and artificial intelligence needed for sustainable ocean observations to understand, predict and manage human impacts on the ocean.

Key actions include the development of a business model ensuring the long-term economic sustainability of ocean observations. We also need to develop a new generation of sustainability scientists and establish a sustainability forum within Europe bringing together all actors including industry and civil society.

The key messages and actions are also explained in a set of infographics (see below).

The report has been a collaborative effort starting in November 2017 with a planning meeting of 19 leading European experts in the field of marine science and related disciplines to decide on the high-level content. Larger collaborative working groups with representatives from 13 European countries then worked to identify knowledge gaps and draft the recommendations of the report.

The Belgian Federal Government is represented in the European Marine Board by the Belgian Science Policy Office (BELSPO). A scientific communicator from RBINS is delegated for communication aspects and membership of the European Marine Board Communications Panel (EMBCP).

Reanalysis of the first results

Sunday 13th of October 2019

After 10 busy days full of working and adjusting our work, we finally managed to make the temperatures measured at the port presentable and in a good format.

After ten days of hard work the team (Zacharie, Katrijn, Sylvain, Wilfried, Medard and field expert Victor) finally have the confidence to test there sensors in the field

After reanalysing the data of 3 and 4 October and comparing them with the GPS shield output we can come up with the following results:

Results of the sensor left at the port of Cotonou

The conclusion of these measurements is that the system is too unstable to produce good results and the gps module uses a lot of battery. After removing the GPS module and stabilizing the system we found the following results:

The conclusion of these measurements is that the addition of shock absorbers  proved very beneficial, there was one power cut that happened during the recollection of the system. The results can be positioned in time in a reliable manner.

On monday, when we will analyse the results gathered during the weekend, we will see if these conclusions can be hold in a real experimental set up.

Putting the system to the test

Friday, October 11th 2019

Report and pictures: Medard Honfo, Katrijn Baetens

After several days of preparation, a stable system was developed so we have the confidence to put the system to the test on the lake itself. After the last verifications our team (Zacharie Sohou, Katrijn Baetens, Medard Honfo, Sylvain Amoussou) and Mr Victor Okpeitcha,an oceanographic ingeneer of IRD/IRHOB took “une pirogue”, a local type of boat, to deposit three thermometers. The stations were next to existing stations of IRD/IRHOB, this will help the validation of our system and avoid double work.

Map of the positions were the sensors are released.
Station 1 (yellow) in the middle of the canal.
station 2 (orange) in the middle of the lake, this was not evident, luckily we got help from local fishermen
Station 3: A permanent station installed by IRD/IRHOB (blue)

Methodology used to install the sensors:

Step 1: fix a perforated pipe in the water

Step 2: Put the sensor inside, the sensor will float on the water

Step 3: close the system and put a lock on it

Fixing the sensors was not always straightforward

Production of more sensors and connection to the internet

Today the students working on this project have assembled and configured their sensors independently. They also tested other types of containers made of local materials.

The new container type indeed was waterproof
The students working together to get the configuration of their sensor right.

Today we finally managed to attach the module system to our sensor, unfortunately we did not arrive to make it reliable enough to attach it to the operational system.

The first succesfull messages sent by the sensor

We ended the day by recollecting the second testtype we deposited at the port yesterday.

Adding a shock absorber to the system

Today we kept improving the system, we noticed the data gaps originated from small shocks that the batterie containers were not able to absorb, hence we searched for different methods to add a shock absorber to the system. The pictures show some of the ideas we had, in the end we kept it simple and just added some padding to the box. In the evening we put the box back to the port for a second test.

First data gave insights in how to improve the sensor

Monday 7th of October 2019

Report and figure: Sylvain Amoussou

We analyzed the data of the first prototype. The prototype has been activated at 5 pm on Friday, October 2019 as Wilfried described in the last report.
The figure shows the temperature measured by the prototype from 5 pm local time on Friday. The figure1 (a) shows that the temperature is almost constant from 5 pm to around 7 pm, the temperature decreases and oscillates overnight. The figure 1 (b) show the temperature from 12 am to 8am UTM time. The temperature still oscillated from 12 am to 5 am UTM. But after that, the temperature is almost constan, the oscillations started  when the sun went down and stopped when it went under.

Data gathered with the prototype during 3 October (a) and 4 October (b)at the port of Cotonou.

Today we also further improved our model:

  • The prototype has stopped for during the night, luckily it started back independently.
  • We verified the voltage on the batteries. We noticed that the remaining voltage was 6,28 V which is half of the 12V of the fully charged battery pack. We still need to further investigate if this is acceptable.
  • In the future we would like to use a gsm module in stead of a gps module, this will allow to transfer data without having to open the box. We found a solution to charge the lithion/ion battery that charges this module.

Production of more sensors and retrieval of thermometer at the port of Cotonou

Friday the 4th of October 2019,

Today we prepared the composition of a different type of sensor containing a GSM system in stead of a GPS. We collected the thermometer we left at the port yesterday, the thermometer was still switched on, a promising sign. On monday we will retrieve and analyse the data inside.

In order to reach the goal of today (composing a new sensor) different chores had to be executed:
Buying SIM cards

Buying SIM cards with a good formula, not so easy as it seems

We discussed several options for new thermometer containers and went of to the market in search of the ultimate box.

Making sure the boxes are suitable for our sensor system

Trying to find battery chargers.

Négotiations at the market for finding good chargers

Collecting the thermometer at the port of Cotonou, the light was still on, so at least the batteries were still working. After the weekend we will analyze and evaluate what we have done so far. We keep you posted.

After 24 hours the thermometer was still switched on

The first session started at 9:00 in the morning in the presence of Katrijn Baetens of RBINS, dr. Zacharie Sohou, the director of IRHOB, dr George Degbé et mr. Médard Honfo of IRHOB. There is also an important participation of students selected for this project: Mr Sylvain Amoussou and Mr  Wilfried Sintondji.

After an introduction to the project Katrijn Baetens présented all the parts and materials that are needed to develop the thermometers. During this occasion she used the prototype developed in Belgium to demonstrate how everything works. After this each student was trusted with a task to copy the prototype and get the hang of the system.  Some of the tasks needed are:

  • Constructing and testing if the box containing the electronics is waterproof

    The box remained waterproof during lab testing
  • Checking the voltage of the system
  • Test the wiring of the new thermometer system on a breadboard
  • Double check if the prototype is working

    The prototype works independently and the GPS receives a signal
  • Programming the thermometer with the desirable time parameters
The students working hard on their assigned tasks. Médard on the left is wiring the new thermometers, Sylvain in the middle is preparing a new waterproof box and Wilfried on the right is isolating the electronic wires.

At the end of the day we were able to test our first prototype in the waters of the port of Cotonou.

Development of a Methodology to Acquire a Spatiotemporal Series of Physicochemical Parameters of the Coastal Marine Environment of Benin

IRHOB and RBINS developed a first prototype of an arduino based temperature  sensor that is waterproof. This is done in the framework of a CEBioS/BBI project. The cost of this model was 56 euro, which is 16 euro more than initially expected, this was mainly because of the inclusion of an expensive GPS module of 18 euro. The next step is to investigate where future  budget cuts can be made. It is difficult to compare the price of our prototype with market prices as a gps and storage of data on an SD card is included in this model. The coming weeks the prototype will be improved and tested in the field, we will keep you posted.

The overall objective of this Project is to foster long-term cooperation between IRHOB, the University of Abomey-Calavi (UAC) in Benin, and the Royal Belgian Institute of Natural Sciences (RBINS) on the development of a methodology to acquire reliable scientific data for rational management and the conservation of aquatic resources in Benin, using sound scientific, technical, and socioeconomic advice. BBI funding enables cooperation in manufacturing Arduino sensors in order to measure physicochemical water quality parameters, such as temperature, salinity, acidity and dissolved oxygen, of the marine and lacustrine environment around Cotonou in Benin. This data collection will constitute the first step towards constructing habitat suitability maps.

The project is mainly sponsored by the Bio-Bridge initiative and co-sponsored by the CEBioS programme of RBINS.

The concept of the methodology is explained in this short movie:
